construction of various types (with a bay window, with windows, with a balcony, with a cuckoo), photo

The sloping roof is a practical and effective design that gives the building a stylish look. Exist various options broken roofs, each of which has its own characteristics and typical construction methods. All this must be taken into account when building broken roof with your own hands.

Design features of broken roofs

The sloping roof got its name due to the design, suggesting an unusual shape and a large number of broken lines. At the same time, a rather spacious room is formed in the attic area, ideal for arranging an attic. Thus, the sloping roof is original decoration, a practical element of a residential building and does not require particularly complex maintenance during operation.

The four-pitched version of the sloping roof allows you to equip a spacious attic on the second floor of the house

The design of the sloping roof is unusual in appearance and has certain internal features. One of the main rules for arranging such a roof is that the width of the house must be at least 6 m. This allows you to create a comfortable attic space and ensure the reliability of the roof. For this purpose, four-sided options are most in demand, having one upper and two additional lateral ribs. In any case, the broken type design includes the following main elements:

A feature of a broken roof is the presence of a fracture of two side slopes. A roof of this type can also have a larger number of planes, then the truss system becomes more complicated and additional ribs are formed at the intersection of adjacent slopes. With a span width of more than 6 m, reinforcement beams and rafter elements are supported by an internal load-bearing partition. In the lower slopes they often equip window openings for loft space.

Attic windows are usually located at the end of the roof

The sloping roof allows you to equip the upper residential floor without the significant costs required in the construction of a full-fledged two-story building. In addition to four-slope options, there are more complex types, for example, a tent-shaped roof. In any case, the greater the number of ribs in the area of ​​plane fractures, the more difficult the design and calculation of the structure parameters.

Types of broken roofs

The general form of sloping roofs suggests the presence of more than two slopes. At the same time, additional elements may be present in the structure, which significantly complicate the process of its construction. One of the spectacular options is a sloping roof with a bay window. Such a design often has 4 slopes, and at the ends there is a protrusion for the window.

The bay window fits well into the design of a sloping hip or gable type roof

Bay window is a small ledge, equipped on the roof. An attic window can be installed in it. The rafter system may provide for certain features of the device of this element, for example, a reinforced frame in the bay window area. Sometimes the ledge is arranged as part of the top of the wall, and the roof of the bay window is given a broken shape. In this case, the frame of the ledge can be made of the same material as the walls of the main structure.

In the place where the bay window is arranged, the roof has a broken shape

A sloping roof for an attic may have windows. They are equipped from the end of the roof or on the surface of the slopes. In the first case, the construction involves the preparation of the crate of gables with openings for windows. In the second option, holes for windows are prepared in the rafter system, and the arrangement of the roof is carried out taking into account these areas. The size of the windows is determined depending on the area of ​​\u200b\u200bthe slopes.

Windows in the attic under a sloping roof can be located on the gables or on the surfaces of the slopes

The arrangement of a sloping roof with a balcony is a popular option, because this design is practical and increases the functionality and comfort of the attic. Most often, the balcony is located at the end, because it is easier to mount it on a straight wall. When a small balcony is located on the pitched part of the roof, it is required exact calculation and thoughtful design of the base. In any case, the load on the wall, which is the basis for the balcony, increases and the use of lightweight materials is required.

Above the balcony, you need to build a separate part of the roof, the shape of which depends on the developer's imagination

On pitched or sloping roofs various types you can create a cuckoo. This part is a small ledge in which the window is mounted. Such an element allows not to make the windows inclined, but to create openings vertically and protect them from above with a roofing. But the construction of the cuckoo leads to a decrease in the bearing capacity of the truss system. This increases the risk of leaks in the area where the ledge roof adjoins the main roof. Therefore, before erecting the cuckoo, it is necessary to choose the optimal shape of the roof over the ledge and the method of its installation.

Before the construction of a broken roof with a cuckoo, a project is necessarily developed load-bearing structure roofing

The main stages of installation

Before starting construction, it is necessary to determine the type of roof, taking into account the dimensions of the building, and calculate the load on the walls. All these operations are carried out in the design process. Then a drawing is drawn up, which indicates the features of the connection of the truss elements and their dimensions.

Installation is carried out according to the drawing, which reflects the dimensions and design features

The truss system is built from wooden beam section 150x150 mm. All wooden parts are pre-treated with a special fire impregnation, which makes the structure safer. The main stages of work are as follows:

A roof with broken slopes makes it easy to make the building unusual, and the attic functional. To achieve these goals, it is worth choosing the appropriate variant of the sloping roof and carry out the installation, taking into account the technology and calculating all the parameters.

truss system and rafters of a four-pitched roof with a bay window + photos of drawings and diagrams

A hip (four-pitched, hipped) roof is one of the design options when additional slopes are built in place of the gables.

However, hip structures are widespread, especially in areas with frequent changes in wind direction.

It turns out a roof that has inclined planes on all sides, which creates a lot of advantageous positions:

• The absence of gables makes the load on the foundation less, in addition, it is distributed absolutely evenly.
• The wind load on the slope is much lower than on the vertical plane.
• The cost of finishing the gables is excluded from the total repair estimate.
• In decorative terms, the hip roof looks more solid, assembled.

The disadvantages of this design are:

• Increased complexity of the design of the truss system.
• Greater consumption of roofing material, which creates additional dangerous areas of possible leaks.
• The presence of bursting loads on load-bearing walls, necessitating ligaments of the lower bases of the slopes.

Hip roof: truss system

The main design feature of the tent-type truss system is the presence of diagonal ribs connecting the corner points of the roof with the ridge beam, which is shorter than the entire roof (the classic hipped roof does not have a ridge at all, the ribs converge at one point).

In the rafter system, these ribs are called angular, or diagonal. Their presence requires the installation of both full-fledged rafters going from the ridge to the base - the Mauerlat, and shortened elements - sprigs connecting the base and diagonal rafters.

hipped roof scheme

Four-pitched roof: elements of the truss system

The elements of the hip-type truss system have a more numerous composition than with a gable design. The truss system of a hipped roof consists of the following parts:

• Mauerlat. Beam laid around the perimeter bearing walls and which is the basis for the entire truss system.
• Sill. A horizontal beam of the same section as the Mauerlat, located along longitudinal axis roof and serving as a support for the racks of the run. A layer of waterproofing is required between the ceiling and the bed.
• Sprengel. An element that binds and reinforces the corner joints of the Mauerlat bars. It is made from the same beam as the Mauerlat and is installed diagonally to it.
• Puff. Connecting elements connecting the parallel bars of the Mauerlat along the long side. Remove the bursting load from the load-bearing walls.
• Rack. A vertical element supported by a puff and supporting a ridge beam.
• Run. Skate beam.
• Diagonal (angular, oblique) rafter. It connects the corners of the mauerlat with the ends of the run, forming ribs - the junction of the roof planes.
• Rafter. Inclined elements based on the Mauerlat from below and on the run from above.
• Narozhniki. These are the elements that rest on top of the diagonal edges. Essentially, these are rafters cut to the length required at a given point.
• Struts. Reinforcing elements, spacers located perpendicular to the rafters and resting at an angle on the puffs.

The designs of all elements may deviate from the generally accepted scheme due to the need caused by the design features of this building, but the scheme as a whole almost always consists of the named details and does not have any radical changes.

Diagonal rafter legs

The elements of the rafter system, which form the ribs connecting the planes of the slopes, are called diagonal (sloping, angular) rafter legs.

Strictly speaking, diagonal and oblique are not quite identical elements, since the former are attached outside the corners of the Mauerlat, and the latter from the inside.

Otherwise, all properties are the same.

Corner elements have certain features:

• Diagonal length rafter legs significantly exceeds the length of straight rafters.
• Diagonal rafter legs serve as a support for the sprigs on both sides of the connected planes.

The presence of such features creates an increased - about one and a half times - load on the rafters compared to conventional ones. Their length exceeds the usual length of the boards from which the rafters are made, therefore, for the manufacture of sloping boards, they are rallied - they are joined along the face in two layers.

This solves several problems at once:

• You can make beams of any desired length.
• Possibility to use one modular material size.

Under the diagonal rafter, it is necessary to install one or two supports (depending on the length), and the location of the support is not in the middle, as it would seem at first glance, but at a distance of one third or a quarter of the entire length of the rafter, counting from the top point, since it is in this area is the place of greatest stress.

CAREFULLY!

Roof rafters located in the valleys have the opposite location of the point of maximum effort - about one third to a quarter of the length from below.

Diagonal rafter legs

As a support for diagonal rafters, either struts or vertical posts made of timber or paired boards can be used. The post can rest directly on the ceiling, through a layer of waterproofing and a wooden lining.

This requires sufficient rigidity and strength of the overlap. If there are no such conditions, then a strut is used, based on the bed and supporting the rafter in given point.

The angle of inclination of the strut in this case does not play a role, the main thing is the connection point, i.e. place of load concentration. With a rafter length of up to 7.5 m, a brace from the upper point of maximum load is sufficient, and with a length of more than 9 m, an additional stand at the bottom is required.

This can be either a support on the ceiling, if it allows, or a support on a sprengel - the so-called. trussed truss - a stand reinforced with struts on the sides.

Supports for diagonal rafters

The device of the conjurers

In the lower part, the sprigs are the same rafters, they have a completely similar method of attachment to the Mauerlat, the same installation step. Mounted strictly at right angles to the base, the upper part - to the corner rafter leg.

Fastening is carried out with at least two nails or other elements. The upper part of the box is cut at the right angle to the horizontal and to the diagonal rafter, to provide a tighter fit and guarantee resistance to stress.

Hip roof over bay window

A bay window is a solid-looking and decorating building, which is a small extension, a ledge in the wall, which performs mainly decorative functions. The section of the roof above the bay window can be any type of structure, but most often the option most suitable for the shape and section of the bay window is used.

The hip roof above the bay window may have an adjoining shape, i.e. be a half of a hip roof, a complex of three planes. Alternatively, there may be a dominant dome over the bay window, towering above the main roof.

In any case, the construction of such a structure is a difficult task, and the complexity is not in the technical sense, but in the design and calculation work. The combination of several planes into one ensemble is a complex problem that requires accurate calculations and careful thoughtful work.

ATTENTION!

Lack of experience, combined with haste, can lead to inconsistencies or miscalculations leading to violations of the tightness of the roof and a decrease in structural strength.

There are important points that play a significant role - for example, the angle of inclination of the bay window slopes should correspond to the angle of inclination of the main roof, the length of the fillies should also be in harmony with all roof overhangs.

The main feature is the combination of hip and valley elements, therefore the construction of the main truss system should be carried out in parallel or before the bay window in order to avoid undesirable discrepancies in the geometry of the system.

Hip roof over bay window

Step-by-step instructions for installing a hip truss system

The description will begin from the moment the mauerlat is laid, all previous operations are considered completed, the floor is completely ready.

Also completed all the calculation and design work.

There is prepared (dried) material - timber and edged board from conifers, as the most suitable for the construction of a truss system in all respects.

For correct installation elements of the truss system, it is necessary to stock up with connecting elements that allow some movement of parts in relation to each other.

This is necessary to compensate for the shrinkage processes of the walls, foundation and the system itself. This is especially important for some load-bearing elements based on the Mauerlat.

Movement of the base with fixed connections of the main components can lead to loosening of the connections and the formation of leaks.

Consider the stages of construction of the hip truss system:

1. Mauerlat installation. The beam is laid on a waterproofed base, fixed with studs. If necessary, the segments are connected along the length of the "half-tree", with reinforcement of the joints with nails. Fasteners are installed immediately.
2. Mauerlat corners are reinforced with sprengels.
3. Bed installation. One or two (depending on the project) beds are laid on a waterproofed base.
4. Racks are installed on which the run is attached. Thus, the supporting skeleton of the truss system is created.
5. Diagonal rafter legs are being installed. Immediately, depending on the length, struts and (or) racks are mounted.
6. Rafters are mounted according to design data. They are immediately adjusted in length / angle and sprigs are installed. All elements, if necessary, are reinforced with struts.
7. The rafters at the points of attachment to the base and to the run are additionally reinforced with brackets, wooden blocks and other fasteners.

Actually, the installation of the truss system at this stage is completed. Further work consists in creating a roofing pie, constructing a batten, roofing, etc.

It should be taken into account the impossibility of full and detailed coverage of all the nuances and trifles on which the high-quality and reliable construction of the truss system depends, since there are many of them and all of them are worthy of separate consideration. However, the general sequence is reflected in sufficient detail.

The creation of a hip truss system is not so much a complicated process as a responsible and dangerous one in that the mistakes made on early stages become noticeable much later.

Therefore, it is very important before starting work to draw up detailed plan work, ensure full compliance with the project and do everything as neatly as possible. The whole structure rests on the joints wooden parts Therefore, it is desirable to have experience and skills in working with wood.

Without the possession of this knowledge, it is better to seek help from specialists, since the responsibility of the truss system for the preservation of the functional qualities of the entire building is too great.

Balcony roof options above the bay window

Houses with a bay window are aristocratic buildings that have become known since the construction of fortresses. Previously, this detail was used purely for practical purposes - for convenience, to protect the fortress and better view. Now bay windows perform primarily a decorative function. These buildings are distinguished by the complex structure of not only the building itself, but also its roof. That is why we will consider roof options for a balcony above a bay window.

Bay window characteristic

A bay window is a structure protruding beyond the bearing walls, which is similar in appearance to a balcony, but has main walls. It is possible to carry out such a structure not only during the construction of the building, but also to attach the bay window structure to an already finished building.

Thanks to the presence of a bay window, the facade of the house looks amazing, and inside the situation changes, thanks to the unique design of the walls. A maximum of natural light will enter such a room due to the presence of a large number of windows on the bay window. There are also often projects where windows are arranged from floor to ceiling, which allows you to observe the landscape without any restrictions. Due to the implementation of the bay window, the useful area of ​​​​the house increases, and it can be used as an office, dining room, children's room, or in some other way, depending on the owner's desire.

The most difficult thing in the design of a bay window is the design and construction of a roof over it, so this issue should be discussed in more detail.

Bay window roof options

The main rule when making a bay roof is its combination with the main roof of the building. The construction of such a roof is quite a difficult task. Even not all professionals undertake such a thing, not to mention beginners. Any mistake or defect in the design of the bay window roof can affect it not in the best way and lead to disastrous consequences.

The bay window in its shape can be rounded, rectangular or multifaceted. Based on the shape of its design, one or another version of the roof is being built. Roof configurations above the bay window can be as follows:

The first two options are distinguished by the complexity of the design, so for their construction you will definitely need a person who has sufficient qualifications and experience in such work. The latter can be done independently, but, again, by those who know the basics construction works for the construction of roofs on bay windows. But in any case, it is better to entrust the work to a professional so as not to worry about the possibility of improper installation and the problems that may arise during operation.

Roof device

First of all, it is worth noting that the rafters for such a roof are made of timber with a smaller section, since the load on the bay window will be much less than on the main roof. As already mentioned, the design of the roof for the bay window can be different, but it is either separate or connected to the main building. In any case, the roof is pre-designed and calculated.

So, the construction of a roof for a bay window follows the following algorithm with strict adherence to the process technology:

Conclusion

A bay roof created using technology will delight its owners with an original appearance and reliable protection from external influences. If there is no self-confidence, then it is better to invite professional builders who will create a solid structure that can last for many years.

Today they are considered very fashionable, but when erecting such, difficulties arise in the process of decorating a roof over them. The arrangement of roofs should be in harmony with the design of the general structure and the design of the main roof, complementing and improving the style. Depending on the form used different types roofs, but the hip is considered the most common.

A hip roof with a bay window has a number of features that must be considered when building it.

• The design has high strength characteristics, durability and unusual appearance.
• During its construction, it is possible to equip a residential attic room, since the process of creating skylights is very simple.
• The hip roof has four slopes, which are tilted on all sides. Two of them are considered the main ones, and two are lateral, located between the first two. Depending on the type of design, there may be more slopes.
• The classic hip roof model has two inclined pairs of sides, two of which are in the shape of a triangle, and two are in the shape of a trapezoid. BUT roof structure has two vertices connected by a ridge.
• The most time-consuming and responsible process is the construction of a hip roof with a bay window. The slightest error in the calculations and drawing up the drawing will lead to possible deformation roof structure.
• A hip roof with a bay window can be independent, or it can be combined with the roof frame of the entire structure.

Important! The rafters have a smaller section than the main rafter legs of the main roof frame, this is due to the fact that these elements are affected by the least load.

Advantages and disadvantages

A hip roof with a bay window has the following advantages:

• The roof structure has an attractive and original design, which makes the structure unusual.
• The hip roof is resistant to wind loads, due to the lack of gables. The smaller the angle of the slopes of the structure, the less the wind affects the truss frame.
• The streamlined shape of all sides has good resistance to a variety of precipitation.
• The process of warming such a roof is simplified by the fact that the cake is inside the structure.
• Depending on the height and slope of the sides of the roof, it is possible to use the interior space for decorating a living room.
• The design of the roof can be with a large overhang, thereby providing additional protection for the walls of the house.
• Due to the absence of gables at the hip roof, the load on the foundation of the house is distributed evenly, and it also becomes much less.

Flaws:

• The disadvantage of such structures is the complexity of their construction. If even the slightest error is allowed, the reliability of the design will be in question.
• The construction of such a roof requires a lot of money.

Varieties

The hip roof is divided into several types, depending on the shape of its design.

classic look

The diagonal ribs of the structure rest on the ridge run, and the overhangs are at the same height.

hipped roof

Has no skate run. All edges of the structure are reduced to one point. This type of roof is not suitable for decorating buildings with a bay window, since the shape of the house box should be square.

Semi-shaft view

It differs from the classical view by the presence of gables in which windows are installed for arranging a living attic room. This type is divided into subspecies, and some of them can be used to equip buildings with a bay window.

broken roof

This type consists of complex design, since all sides have a different size, with a discrepancy under different biases. This type gives the house a spectacular and original look and is great for arranging bay windows. A roof with a bay window, the rafter system of which has a broken frame, allows you to save a maximum of free space for decorating an attic space.

Roof drawing and calculation of its area

Before erecting a roof with a bay window, it is necessary to draw up a project that provides for the preparation of a diagram of the future structure, as well as the calculation of the necessary building materials. The calculation and drawing up of the scheme is carried out in the following sequence:

The choice of the angle of inclination of the sides

The choice of the angle of inclination of the roof slopes is made taking into account the following criteria:

• In what climatic conditions is the building located, as well as wind load. With a heavy load, the roof slope should be the most gentle. The lower the slope, the stronger the structure.
• With a large amount of precipitation, the roof slope should, on the contrary, be as high as possible so that they roll off in a timely manner, thereby not affecting the roof surface.
• A variety of roofing material, since each type has its own requirements for the crate, and also have different weights. For each type, there are some restrictions on the slope of the ramp:

Important! The higher the angle of inclination, the larger the roof area, which entails the purchase of additional building materials. This nuance must be taken into account when drawing up a drawing.

Drafting a project

Taking into account all the features, you can proceed to the design of the roof structure with drawing up a drawing and calculation building materials. For this you need:

• Measure the parameters of the house and ledge: height, width and length.
• Schematically display the facade and end of the building on paper, using a certain scale.
• Depending on the features of the house, choose the type of hip roof.
• Having decided on the height of the roof, according to the above criteria, draw several models of the roof frame on one of the sketches. Having chosen the most suitable option, it is necessary to designate the angle of inclination of the sides of the structure. To do this, you need to use a protractor.
• Next, the location of the rafters is applied to the drawing, marking them with dots. To do this, the length of the wall is divided into equal segments, which will be the step between the lines.
• The step between the lines also depends on the section and characteristics of the wood used.
• The need for roof insulation. In this case, the location of the rafters must correspond to the width of the insulation.
• The drawing should also indicate the rafters of the bay window.
• If the type of roof provides for a ridge run, it must be taken into account that it must connect a pair of beams of the truss system. On one of the drawings, you need to designate equal sections from each edge of the wall.
• From the received sketches, one large drawing is compiled, which will also be useful in the future for calculating materials.

Important! The presence of the project and the schematic representation of the design is a good help in the procurement of materials, the manufacture of blanks and in the process of installation work.

How is the area calculated?

The calculation of building materials is carried out according to certain formulas, taking into account the slope of the roof and the area of ​​​​the roofing surface.

For the calculation, you will also need the following data:

• The presence of chimneys and dormer windows in the roof. Their presence increases the consumption of building materials.
• The length of the slope, its calculation is made from the ridge to the edge of the eaves.
• The parameters of the firewall walls, overhangs, parapets, and other parts are calculated.

To obtain accurate data during the calculation, it is recommended to seek help from professionals or use a special program on the Internet. When deciding to perform the calculation on your own, it is recommended to divide the roof surface into separate sections, which will make it easy to calculate their area. After that, all values ​​are summed up.

The more accurately the area of ​​\u200b\u200bthe roofing surface is calculated, the less will be the cost of purchasing excess building materials.

Advice! To obtain a reliable and durable roof structure for its construction, it is necessary to purchase well-dried beams.

Construction tools

To build a hip roof with a bay window, you will need the following tool:

• level;
• pencil;
• roulette;
• lace for marking;
• hacksaw;
• stapler;
• a hammer;
• electric drill;
• cutting scissors;
• riveter.

Preparation of materials and tools is carried out before the installation process, so that in the process of work not to be distracted by their search.

To simplify measurements and for their accuracy, it is recommended to replace the tape measure with a measuring rail, which can be made of plywood, 5 cm wide, applying the main measurements on it.

Features of the installation process

Any construction process has its own characteristics, and the construction of a hip roof with a bay window is no exception.

• Before starting the installation of the frame, it is recommended that all lumber be treated with an antiseptic.
• To make and fix the truss frame, it is necessary to prepare a Mauerlat, which is laid on top of the walls, around the entire perimeter of the building. It performs the function of binding the truss system to the walls of the building.
• Since the intermediate rafters have a steep slope, unlike rafters, boards with parameters of at least 5 * 15 cm are used for their manufacture.
• When erecting a rafter frame, vertical racks are first installed that support the ridge run. The racks are fixed to the central beam using a system of slopes.
• Fastening of short rafters is carried out not to the ridge bar, but to the sloping elements of the frame. The slope angles of the intermediate and short rafters must match.
• The bay window truss system, the photo diagrams of which are presented above, should be in harmony with the overall design, but at the same time it may have a smaller section of the beams, since the load imposed by external climatic factors is much lower.
• The bars used to build the rafter system and run the ridge must have the same cross section. If this requirement is met, the structure will be strong and its early deformation will not occur.
• The intermediate rafters are fastened to the ridge run and the upper part of the harness.
• When erecting a roof of low height, it is necessary to install additional racks-supports.
• To obtain a solid roof structure, it is recommended to use lumber of their softwood, without defects and knots.
• For high wind loads, the diagonal and center bars should be thick.
• After the construction of the frame, its hydro- and thermal insulation is made, on a pre-made crate.

Summing up, we can say that for the arrangement of a building with a bay window, a hip roof is often used, which has several varieties and, depending on the shape of the protrusion, the most suitable type is selected.

Before the construction of the truss system, it is necessary to draw up a project that involves drawing up a drawing and calculating building materials. To obtain a strong and durable design, it is better to entrust the creation of a project to professionals.

Modern projects of cottages and country houses include a large number of a wide variety of structural elements necessary to solve various functional problems. Often, construction companies offer for construction options for a house with a bay window - a small space inside the building that extends beyond the facade of the structure. From the point of view of technology, a device of this design does not cause problems, but here Special attention it is worth giving the roof.

Typically, a bay window is presented in suburban housing construction as a covered balcony. At the same time, its walls are integral parts of the floors of the house. The shape of the bay window design depends on the design solution, but in most cases it is semicircular, multifaceted, trapezoidal. In addition, it is possible to distinguish types of roof shapes, usually installed in private houses above the bay window:

• Multi-forceps;
• hip;
• decorative;
• In the form of a hemisphere.

Important! Preference is often given to a hip roof with a bay window, because it is the simplest in execution, according to professionals.

Such a design does not require serious financial and labor costs, and it is also quite technologically advanced and reliably protects the room inside from various negative influences.

Preparation process

You need to decide on the choice of a roof over a bay window at the design stage of planning a house. The roof is mostly multi-pitched, so you will definitely have to make various skates, grooves and other related structural elements designed to remove rain and debris.

Initially, it is worth noting that the construction of a valley roof is a rather complicated process, it requires a lot of labor, so it is best to entrust this task to highly qualified specialists. It is not recommended to do this work on your own. As with any modern roof, a reliable truss system will definitely be required here, and it is quite difficult to do it yourself without proper experience and skills.

On the initial stage preparation of the roof device over the bay window needs to be done reinforced belt. It is made from cement mortar and bars of reinforcement or metal mesh. This belt performs the following functions:

• It acts as a support for the beams that support the truss system. Without such beams, it simply cannot function.
• It also enhances brickwork and unloads the lintels of window structures.
• In addition, the belt is required to reinforce the walls of the bay window, which is achieved by tying them to the walls of the house.

Important! When choosing a roofing material, it is worth starting from economic opportunities and personal preferences, while not forgetting about its functional qualities.

According to experts, in the role of roofing for bay windows of private houses, the most optimal solution there will be a choice of one of the types of modern tiles (natural, bituminous, metal tiles, and so on). This type of roof is able to perfectly harmonize with the design of the bay window.

The device of the truss system

A rafter frame is a must for most types of roofs, and bay window roofs are no exception. A bay window truss system has been built, it can be from wooden planks and beams. They are connected to each other and to all other structural elements by means of self-tapping screws, screws and other fasteners. The rafter system should consist of beams of the required sizes, it is worth choosing sizes with a margin in order to cut off the excess directly during the installation process. The principles for performing work on creating a rafter frame in the case of a bay window are not much different from the usual work when installing a hip roof truss system. A power plate is laid along the reinforced belt, and rafter legs are attached to it.

Installation of rafter legs should be carried out at the initial stage. They need to be brought out of the plane of the walls. So further it will be possible to easily form cornice overhangs, which will prevent moisture flowing down the roof from having a negative effect on the material of the walls. To fix various wooden elements of the roof, traditional self-tapping screws or special fasteners that are resistant to corrosion and coated with a layer of galvanized steel are usually used.

Important! The rafter system can be assembled directly on the roof itself, regardless of its device.

A variant is possible in which some individual elements of the truss system will be assembled on the ground. It depends on the constructive solution and the project - whether the roof with a bay window is a sufficiently independent structure, or whether it acts as a continuation of the roof of the house. In those situations when the truss frame for the valley roof is assembled by separate trusses, then after raising them to the roof, they must be attached not only to the Mauerlat, but also to the ridge. They are usually attached to the latter with steel plates.

Now you can find on the Internet a lot of photos of various hip roofs with a bay window, get detailed information about the construction of rafters for any of them and read a lot of tips on the process of their construction. But before starting work, it is still worth consulting with knowledgeable people to avoid unnecessary waste of money, time and nerves.

This house box (11x13.5 m) should be covered with a gable hip roof and the bay window is covered with a hipped roof. A bay window is located on the side of the end wall.

An armored belt is arranged along the upper level of the wall of the 2nd floor, to which the Mauerlat will be attached.

Mauerlat installation

First you need to install the Mauerlat and the beds. This is done from a bar with a section of 200x200 mm.

Installation of Mauerlat and beds

Mauerlat is installed around the perimeter of the box, and the beds along interior walls. Between the armored belt and the Mauerlat, it is necessary to install waterproofing in the form of two layers of roofing material or other waterproofing material.

After that, it is necessary to firmly fix the Mauerlat and the beds to the armored belt.

Installation of the main beams of the hip roof

Beams of the main roof with a section of 100x200 mm are installed. From the side of the bay window, a beam of 200x200 mm timber is installed. It is necessary to support the hip sprigs from the side of the bay window.

Installing Bay Bay Beams

Bay window beams are installed.

At this stage of work, it is necessary to ensure the same overhang of the eaves from the side of the bay window and from the side of the main house, which should be equal to 0.5 m.

Installation of support frames and hip roof truss system

Then you need to install the base frame. The height of the support frame corresponds to the height of the roof.

Base frame installation

At the top there is a ridge run from a board with a section of 50x200 mm. It must be said that the roof can be mounted both element by element and complex installation.

roof truss

When the truss truss is assembled, which is then installed in the design position in a rotary way. But for this it is necessary to have a sufficient number of workers (min - 4 people), and with element-by-element installation, 2 people are enough.

On the side of the bay window there is also a ridge run and a strut, and on the central pillar of the bay window there is a centering core on which all the rafters of the bay window will converge.

Ridge run from the side of the bay window

This centering element has a width of 30 cm and a height of approximately 50 cm.

On the next step rafters of the main roof are installed.

If the rafters are more than 6 m ( standard size lumber) then they will have to be spliced. This is done at the top where there will be the least effort.

The next step is the installation of corner rafters - two on one side and two on the other side. Next, the guards are installed. Rafters and rafters on the main slopes have a section of 50x200 mm. The cross section of the hip joint is 50x150 mm. There will be no snow here, so there is no need to provide for particularly massive structures.

Then the bay window rafters are installed. Their upper edge converges on the centering core.

Installation of hip roof stiffeners

At the next stage, stiffening ties are installed - struts, supports, puffs. These are all kinds of roof elements that provide rigidity and stability of the roof.

Roof Stiffness Ties

Inside this farm there is an opening about 2.2 x 5.5 m in size and this is quite enough for a comfortable attic. At this stage, the roof frame can be considered complete.

All roof elements must be rigidly connected to each other, and all wooden structures treated with flame retardants and antiseptics to increase their fire resistance and durability, i.e. their resistance to decay.

roof lathing

The next step is to install the crate. First, the main roof is sheathed, then a valley bar is installed to mate the main roof and the bay window roof.

For owners of houses with a bay window important point is the installation of the roof. Which version of the roof over the ledge to choose and how to mount it correctly - these are the questions that arise in the first place.

Briefly about the main thing. What is a bay window?

Bay window- this is the protruding part of the building, having the shape of a half circle or polygon. Equipped with several openings for windows or made glazed around the entire perimeter. As a rule, a separate roof is made for it. This design differs from a closed balcony by the presence of main walls, such as those of the rest of the building. It can be decorated with additional decorative turrets.

Among the main functions of such niches are the following:

• aesthetic. Makes more attractive appearance individual premises or the building as a whole. It is possible to ennoble housing in this way not only outside, but also inside. Such solutions make stylish and original interior premises.
• Increase in usable area. Extensions, whether they are bay windows, balconies or loggias, are erected in order to increase the functional space of the dwelling. Such solutions are especially relevant in small houses. In such premises, an office, a tea corner, a small library, a creative workshop can be equipped. Niches located under the windows are perfect for storing various seasonal clothes or things.
• Additional source of natural light. Since bay windows are made fully or partially glazed, they can be used as one large additional window.

Options for roofing over a bay window

The roof of any building should not only protect the interior from precipitation, wind and dust, but also decorate the house.

There are several main types:

• dome;
• Rectangular;
• Multifaceted.

The roof over the ledge may or may not be structurally connected to the main one. In the second option, timber for the manufacture of rafters can be taken with a smaller section. This is due to the fact that the rafters of the "decorative roof" do not need to withstand heavy loads. Manufactured independent roof from the same materials that were used for the top of the main structure. Now often used for roofing: metal tile, profiled sheet, flexible roof or ordinary slate.

Here is an example of the options for roofs over the ledge:

Roof Construction Instructions

First of all, it is important to determine the design of the future roof, the materials and fasteners necessary for its construction, as well as their number. You can calculate the approximate budget of the work.
The installation of the structure itself begins with erecting a foundation for rafters. This is the so-called reinforced belt. It is made of concrete reinforced with a metal mesh and follows the contours of the walls. Its task is not only to create an additional basis for the rafters, but also to remove excess load from fragile window openings and strengthen the entire structure as a whole.

Next stage - rafter system installation. As a rule, they are collected on the ground and already ready to be lifted up. The lower ends of the beams should protrude beyond the outer edge of the wall for some distance. This is done to organize cornice overhangs. You should carefully observe the proportions when assembling the structure. Not only the appearance of your building depends on this, but also the stability.

This is followed by the installation of the crate, which will subsequently be attached waterproofing and roofing materials. As a waterproofing, ordinary roofing bitumen can be used. The crate is of two types: solid and sparse. The choice of one of them depends on what kind of roofing for the bay window roof you need. For flexible materials, it is better to make a continuous crate. Whereas for a metal tile or profiled sheet, a sparse (cellular) one is also suitable. Lastly, the end plates are installed. They connect the roof of the bay roof with the main one. Thanks to them, reliable insulation of joints is ensured. Water will not flow under them and dirt will not get in, which will allow the layer of hydro and sound insulation to last you much longer. A rectangular or hip roof of a house is made according to approximately the same algorithm. The difference will only be in the shape of the rafters and their number.
