Hip roof with bay window is very popular today, but during installation works there may be some difficulties with the design. The roof must be in harmony with the overall design style buildings. Depending on which type of bay window was chosen during installation, the shape of the roof depends. Hip roof is the most common option.

Advantages and disadvantages of hipped roofs with a bay window

Four-pitched roofs of houses with a bay window have a large number of advantages, among which the following points can be highlighted:

• attractive appearance of the roof structure, original design, thanks to which the structure turns out to be unusual;
• hip roof with bay window is different high level resistance to strong gusts of wind, which is facilitated by the absence of a roofing pediment; the smaller the angle of the roof slope will ultimately be, the less strong wind will affect the rafter system;
• due to the fact that the hip roof with a bay window has a streamlined shape, the structure is highly resistant to various types of natural precipitation;
• since the cake is located inside the structure, this greatly facilitates the insulation process;
• depending on what height and slope will be made hip roof with a bay window, in the future you can use the under-roof space as a living space;
• during the design of the house, the overhang of the roof is made quite large, so that additional protection for the walls of the building can be obtained;
• since the hip structure with a bay window does not have a pediment, this contributes to an even distribution of weight over the foundation, in addition, the load on the foundation is significantly reduced.

Despite the large number of advantages, do not forget about the disadvantages, among which are:

• complex installation process - if during the work a mistake is made, even the smallest, then the level of reliability is immediately called into question;
• for the construction of a hip roof requires a large investment.

Types of hip roofs with a bay window

When deciding to install a hip roof with a bay window in a residential building, it is worth considering the overall shape of the roof.

Attention! Thanks to the bay window with a sloping frame, a large area of ​​the roof space can be saved.

Diagrams of rafter systems of a hip roof with a bay window

After all the features have been taken into account, you can start drawing up drawings for a hip roof with a bay window rafter system. This will require:

• measure the height, length and width of the building;
• on paper, adhering to a certain scale, schematically sketch the facade and ends of the building;
• choose the version of the hip roof, taking into account design features buildings;
• taking into account all the characteristics, draw several options for a roof with a bay window on one of the sketches, and then choose the most suitable one; the angle of inclination must be marked on the drawing;
• the location of the rafters is marked on the drawing (highlighted with dots), the length of the wall is divided into equal segments, due to which a step is obtained for the rafter system;
• it is important to understand that the step for the rafter system largely depends on the section and characteristics of the wood used in the work;
• since insulation is required for a hip roof with a bay window, then during the installation of rafters it is worth taking this moment into account;
• on the drawing mark the location of the rafters for the bay window.

After the sketches are ready, they are combined into one large drawing, which is used later during installation work.

Important! Thanks to a previously prepared drawing, it is possible to calculate the required amount of building material.

Calculation of the area of ​​a hipped roof with a bay window

To perform the calculation, the following data is required:

• the presence of chimneys and dormers - their presence significantly increases consumption building materials;
• length of the slope (measurement is carried out from the ridge to the edge of the eaves);
• parameters of overhangs, parapets.

If the decision is made to carry out all the work independently, then it is recommended to first divide the roof visually into equal sections, which will make it possible to calculate the area much faster.

The more accurate the calculation is, the less likely it is that excess building material will be purchased.

Advice! You can get a reliable roofing structure with a long operational life only if you purchase a high-quality dried timber for the rafter system.

How to make a do-it-yourself hip roof with a bay window

It is possible to carry out installation work yourself if you adhere to the rafter system diagram four pitched roof with a bay window. Initially, it is recommended to take into account all the design features, make the appropriate calculations, and calculate the area. Only after that you can purchase building material in the required quantity.

Installation work is carried out in several stages:

1. Installing the Mauerlat. It is necessary to install a bar on the waterproofing using studs for this purpose. If necessary, the mounted sections are connected with nails. The hood is installed at the same time.
   
   
2. With the help of special latches, the corners of the Mauerlat must be strengthened.
   
3. Fastening the bed. Depending on which project was chosen, 1 or 2 beds are attached to the waterproofing layer. Then, racks are mounted on the roof surface, on which the girders are attached. This will create the skeleton of the roof truss system.
   
   
4. Mounting rafter legs horizontally. Depending on the chosen length, struts or struts are attached. According to the drawn up project, the rafters are installed. At the same time, it is worth adjusting the length and corners of the beads. If necessary, all elements can be additionally reinforced with struts.
   
   
5. In the place where the rafters are adjacent to the base and the purlin, additional reinforcement is required. For these purposes, staples are used.

Must be at hand construction tool, which will be needed during work. You should also not neglect the advice and recommendations from experts.

Photo of hip roofs with a bay window

It is often difficult to choose suitable option... To do this, it is recommended to see a photo of hip roofs with a bay window.

During installation work, you should adhere to the following tips:

• the wood used is treated with special protective compounds;
• during the arrangement of the rafter system, the first step is to lay the vertical racks;
• short rafters are fixed on the frame elements;
• the slope of the intermediate and short rafters must be the same;
• for the rafter system and the ridge run, beams with the same section are used;
• if the roof height is small, then additional supports are installed;
• to obtain the desired level of strength, it is best to use coniferous wood.

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

A hip roof with a bay window has a number of features that must be taken into account when erecting it.

• The design has high strength characteristics, durability and unusual appearance.
• During its construction, it is possible to arrange a living attic room, since the process of creating roof windows very simple.
• The hip roof has four slopes that are inclined on all sides. Two of them are considered main, and two side ones, located between the first two. Depending on the types of construction, there may be more slopes.
• The classic model of a hip roof has two inclined pairs of sides, two of which are in the shape of a triangle, and two in the shape of a trapezoid. A roof structure has two peaks connected by a ridge.
• The most time-consuming and demanding process is the erection of a hip roof with a bay window. The admission of the slightest errors in the calculations and drawing up the drawing will lead to possible deformation of the roofing 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 rafter beams have a smaller section than that of the main rafter legs of the main roof frame, due to the fact that these elements are affected by the least load.

Advantages and disadvantages

Hip roof with 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 rafter frame.
• The streamlined shape of all sides has good resistance to a wide variety of precipitation.
• The process of insulating such a roof is simplified by the fact that the pie is inside the structure.
• Depending on the height and slope of the sides of the roof, it is possible to use the interior to decorate the living room.
• Roof decoration 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 evenly distributed, and it also becomes much less.

Disadvantages:

• The disadvantage of such structures is the complexity of their construction. With the admission of even the slightest error, the reliability of the design will be in question.
• Building such a roof is expensive.

Varieties

Hip roof is divided into several types, depending on the shape of its structure.

Classic look

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

Hipped roof

Does not have a ridge girder. All the edges of the structure converge to one point. For the design of buildings with a bay window, this type of roof is not suitable, since the shape of the house box must be square.

Half-baked view

It differs from the classic look 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.

Sloping roof

This view consists of a complex structure, since all sides are of different sizes, with divergence at different slopes. This look gives the house a spectacular and original look and is great for decorating 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 the 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:

Choosing 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 structure located, as well as the wind load. Under heavy loads, the roof slope should be as flat as possible. 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 down in time without affecting the roof surface.
• Variety roofing material, since each type has its own requirements for the crate, and also have different weights. For each species, there are some restrictions on the slope of the slope:

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 calculating building materials. This requires:

• Measure the parameters of the house and the ledge: height, width and length.
• Sketch the facade and end of the building on paper using a specific scale.
• Depending on the characteristics 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 indicate the angle of inclination of the sides of the structure. To do this, you must use a protractor.
• Further, 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 spacing between the slings 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 bay window rafters.
• If the type of roof provides for a ridge girder, it must be taken into account that it must connect a pair of beams of the rafter system. In one of their drawings, you need to designate equal sections from each edge of the wall.
• From the sketches obtained, one large drawing is compiled, which in the future will also be useful for calculating materials.

Important! The presence of the project and the schematic reflection of the structure 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 made 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 dormers 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 cornice.
• The parameters of the walls of the firewall, overhangs, parapets, and other parts are calculated.

To obtain accurate data when calculating, it is recommended to seek professional help 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 which all values ​​are summed up.

The more accurately the area of ​​the roofing surface is calculated, the less will be the expense for the purchase of excess building materials.

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

Construction tools

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

• level;
• pencil;
• roulette;
• lace for marking;
• hacksaw;
• stapler;
• hammer;
• electric drill;
• slitting shears;
• riveter.

The preparation of materials and tools is carried out before the installation process, so as not to be distracted by their search during the work.

To simplify the measurement and for their accuracy, it is recommended to replace the tape measure with a measuring rod, which can be made of plywood, 5 cm wide, by applying basic measurements to 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 to treat all lumber with an antiseptic.
• To make and secure the rafter frame, it is necessary to prepare a Mauerlat, which is laid on top of the walls, along the entire perimeter of the structure. It performs the function of binding the rafter system to the walls of the building.
• Since the intermediate rafter beams have a steep slope, unlike nipple rafters, boards with parameters of at least 5 * 15 cm are used for their manufacture.
• When erecting a rafter frame, first, vertical posts are installed that support the ridge girder. The racks are fixed to the central beam using a mowing system.
• The fastening of short rafters is carried out not to the ridge bar, but to the frame elements. The slope angles of the intermediate and short rafters must match.
• Rafter system bay windows, the photos of the schemes of which are presented above, should be in harmony with overall design, but at the same time it can have a smaller cross-section of the beams, since the imposed load from external climatic factors is much lower.
• The beams used for the construction of the rafter system and the ridge run must have the same cross section. If this requirement is met, the structure will be strong and will not deform as soon as possible.
• Fastening of intermediate rafters is carried out to the ridge girder and the upper part of the strapping.
• When erecting a roof of low height, it is necessary to install additional supports.
• To obtain a solid roofing structure, it is recommended to use sawn timber from softwood, without defects and knots.
• For high wind loads, the diagonal and center beams should be thick.
• After the construction of the frame, its hydro and thermal insulation is made, on a pre-fabricated crate.

To summarize, we can say that a hip roof is often used to equip a building with a bay window, which has several varieties and, depending on the shape of the protrusion, the most suitable type is chosen.

Before the construction of the rafter system, it is necessary to draw up a project that provides for the drawing up of a drawing and the calculation of building materials. To obtain a strong and durable structure, it is better to entrust the creation of a project to professionals.

A bay window is a part of the room that extends beyond the plane of the facade. The fashion for such architectural solutions has not disappeared since the Middle Ages. Making a bay window on a roof is not easy even for experienced builder... The main secret of construction is experience and knowledge about the features and types of construction, methods of its construction.

Advantages and disadvantages of a roof with a bay window

Externally, the bay window looks like a terrace or balcony. But structurally, it is part of a house with solid walls. Depending on the project, it can occupy several floors, have a semicircle, trapezoid, rectangle or other polyhedron at the base.

Bay window roofs have many advantages:

• aesthetically pleasing appearance;
• good resistance to strong gusts of wind - provided by the absence of a roof gable;
• streamlined shape that makes the roof structure over the bay window reliably protected from different types precipitation;
• facilitated warming process;
• the ability to exploit the under-roof space as a living room or for domestic needs;
• the ability to apply unusual design solutions when arranging the under-roof space;
• a lot of natural light in the rooms;
• additional protection of the load-bearing walls above the bay window due to the large overhang of the roof;
• reduction of the load on the foundation and its more even distribution due to the absence of a roof gable.

There are many advantages to the bay window roof structure, but there are also a number of disadvantages:

• the complexity of installation work - the mistakes made are difficult to correct, and they significantly reduce the reliability of the architectural element and level its merits;
• the erection of a bay window roof requires large financial investments - design and construction work is quite complex and expensive;
• increased heat loss.

Varieties and types of bay window designs

Bay window designs can be of various sizes and shapes. They can also vary in area:

In height, in the form of a bay window, it can be decorated:

Designers and builders can give the bay window almost any shape. The most common are:

1. Trapezium. The sides adjoin the facade at different angles, except for the straight one. The center window is usually larger than the side windows.
   
   
2. Semicircle, or Venetian type of bay window. Gives appearance houses smooth lines. Looks good both from the street and from the inside. TO this type include turrets located at the corners of buildings.
   
   
3. Rectangle. Formed when the sides adjoin the facade at right angles. The interior has the usual parameters, but it does not look so interesting.
   
   
4. Triangle. Not as common as previous designs. However, it looks original.
   
   

There are also more complex geometric shapes. It is they who determine not only the appearance of the building, but also the interior of the premises.

Roof truss system of a house with a bay window

The device of the bay window rafter system consists of a ridge bar, as well as rafters for various purposes. Since the slopes of the roof can have different angles of inclination, there are several types of rafters, the main of which are:

• central intermediate- they are attached to each end of the ridge bar, three pieces;
• angular, or oblique, rafters- serve as the main bearing parts of the structure, are located in the corners of the frame, have the smallest slope in comparison with intermediate rafters;
• intermediate - located from the harness to the ridge, between the central rafters.

When installing the roof truss system, they also install:

• ridge girders - crossbars, directed horizontally and creating support for central and corner rafters;
• outdoor, or short, rafters a - parts of the structure fixed to the corner rafters and strapping and having the same slope;
• Mauerlat - a bar that is attached to the top of the outer walls and evenly distributes the load of the rafters, serving as a base, a connecting link of the roof frame and walls;
• brace - a support for the rafter legs of large spans, allows you to overlap large spans and save the sections of the main beams.

How to calculate the area of ​​a bay window

To measure the area of ​​the bay window, the following tools are used:

• a ruler is the least accurate measuring device that gives large errors;
• tape measure - suitable for measuring small areas;
• laser rangefinder is a tool that shows the most accurate measurement result and makes it possible to carry out work without the help of a partner.

The main problem when calculating the area of ​​a bay window is its complex shape, beveled or rounded. If it is not a rectangle or triangle, but a more complex polygon, it should be divided into several simple shapes.

Further actions are as follows:

1. Measure all sides.
2. Execute a drawing, mark the received data on it.
3. Using the formulas for calculating areas, make calculations for simple shapes.

How to make a bay window with your own hands

The initial stage of building a bay window is drawing up a project, planning a form. In some cases, additional documents have to be drawn up. If the construction of the structure goes in parallel with the construction of the house, then there is no need for them. If the extension of the bay window is carried out to a building that has been in operation for some time, it is required to amend the project and obtain permission for the extension.

Laying the foundation

The structure of the foundation for the bay window structure is similar to the foundation of the building. Monolithic tape is suitable. Stages of its construction:

• digging a trench;
  
  
• formwork creation;
  
  
• insulation;
  
  
• reinforcement;
  
  
• pouring with concrete.
  
  

The foundation needs shrinkage, after which treatment with waterproofing materials is performed.

Erection of a bay window

If a bay window is being erected with your own hands, then without appropriate experience it is not recommended to build it above one floor. Most suitable materials- brick or aerated concrete. Masonry has a number of features that are important to consider:

1. For internal walls, gas silicate blocks or aerated concrete can be used.
2. For external masonry, it is better to take high-quality facing bricks.
3. When using both brick and aerated concrete, it is necessary to correctly calculate the load on the foundation.
4. Thermal insulation should be in the middle layer. It could be mineral wool or more modern spray materials.
5. It is important to provide for waterproofing - membrane film or similar solutions.
6. The bay window and the walls of the building must be of a monolithic structure. This avoids operational problems.

Roof above the bay window

The main rule during its construction is that the roof must harmoniously fit into the overall style of the roof.

In practice, there are several types of roofs above the bay window:

The simplest version of the roof over the bay window is the continuation of the roof of the main building. Its shape depends on the shape of the bay window (semicircular, trapezoidal, rectangular, triangular).

Types of roofs above the bay window

There are the following common types of roofs over bay windows:

1. Hip - performed in buildings of an oblong shape, has a ridge and four slopes, two of which are triangles in shape, two are trapeziums.
   
   
2. Hip - used for small bay windows, makes the building look like a tower, has a large number of edges.
   
   
3. Multi-gable - the most complex structure of the bay window roof with gables and valleys, a type of pitched roof with two or more gables, gable elements with ridge.
   
   
4. Decorative - equipped with additional structures, for example, turrets.
   
   

The main criterion when choosing the type of roof over the bay window is the performance of its functions. The most common hip roof one-storey house with a bay window, the most simple in terms of design. It does not require significant labor and material costs.

Diagram of the roof truss system above the bay window

The rafter system diagram provides for the dimensions, section and exact location of each frame element. In addition, the drawings of rafter systems include the following parameters:

• roof height;
• the angle of inclination of each of the slopes;
• ridge run size;
• span width;
• ways to strengthen the structure;
• features of fastening structural elements.

In the photo, a diagram of the rafter system on the bay window of the hip roof

How to make a roof on a bay window with your own hands

When installing the bay window and roof truss system, as a rule, the same materials are used as for the main roof:

• soft roof;
  
  
• metal tile;
  
  
• corrugated board;
  
  
• slate.
  
  

In addition, the following materials are needed for construction:

• screws, screws and nails;
• roof beams;
• galvanized iron:
• beams for lathing.

Stages of work:

1. The initial stage of work is the preparation of a reinforcing belt. This is a support for the beams, which also makes the masonry more durable. Belt material - concrete and reinforced mesh.
   
   
2. Next, proceed to the installation of the rafter beams. Planks and beams are used, connected with self-tapping screws and screws. They are cut with small gaps, which are removed after the beams are secured.
   
   
3. Before proceeding with the installation of rafters, the angle of inclination of the roof is specified. The rafters are adjusted on the ground, after lifting, they are sewn on the ridge of the roof using metal plates and self-tapping screws, and attached to the rafter beams.
   
   
4. Then the rafter system is covered with a waterproofing material and a crate is built.
   
   
5. They proceed to the most difficult stage of installation, install valleys using various gutters. The lower planks are necessary for the drainage of water and snow. The upper bar serves as a decorative function, hides imperfections. They are attached to the end board, the joints are treated with a sealant.
   
   
6. At the final stage, the roof above the bay window is insulated and hemmed.
   
   

Experienced builders are advised to pay attention to the following points:

1. Before finally choosing the size and type of the roof over the bay window, it is worth making a reduced three-dimensional model.
2. Any lumber that is used in the construction of a roof must be treated with antiseptics.
3. The waterproofing foam must have at least two layers so that the insulation can be placed close to it.
4. The waterproofing film must be well permeable to water vapor.
5. The valleys must be galvanized, since the requirements for their moisture resistance and corrosion resistance are the highest.

Conclusion

The construction of a bay window and a beautiful, reliable roof with skillful hands gives the whole building a respectable look. Making a bay window on the roof means increasing the internal area, transforming the premises into lighter and more spacious ones. Bay window structures create wonderful areas for relaxation and winter gardens, comfortable children's rooms.

Modern projects of cottages and country houses include a large number of a wide variety of structural elements necessary to solve all sorts of functional tasks. Often construction companies options for a house with a bay window are offered for construction - a small space inside the building, extending 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 should be paid to the roof.

Usually, 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 structure depends on the design solution, but in most cases it is semicircular, multifaceted, trapezoidal. In addition, one can distinguish types of roof forms, usually installed in private houses above the bay window:

• Multi-pliers;
• Hip;
• Decorative;
• In the form of a hemisphere.

Important! A hip roof with a bay window is more often preferred, because it is the easiest to perform in the opinion of professionals.

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

Preparation process

You need to decide on the choice of a roof over the 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 sediment and debris.

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

At the initial stage of preparing the roof device above the bay window, you need to make a reinforced belt. It is made from cement mortar and rods of reinforcement or metal mesh. This belt performs the following functions:

• It acts as a support for the beams that support the rafter system. It simply cannot function without such beams.
• It also enhances brickwork and relieves the bulkheads of window structures.
• In addition, the belt is required to strengthen the walls of the bay window, which is achieved by tying them to the walls of the house.

Important! When choosing a material for a roof, 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 would be to choose one of the types of modern tiles (natural, bituminous, metal, and so on). This type of roof can be in perfect harmony with the structure of the bay window.

The device of the rafter system

A rafter frame is a must for most types of roofs, and bay window roofs are no exception. A bay window rafter system can be built 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 the right sizes, it is worth choosing sizes with a margin in order to cut off the excess directly during the installation process. The principles of performing work on creating a frame of rafters in the case of a bay window are not much different from ordinary work when installing a rafter system of a hip roof. The Mauerlat is laid along the reinforced belt, and the rafter legs are attached to it.

The 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 eaves overhangs, which will not allow moisture flowing down the roof to have a negative effect on the material of the walls. To fix various wooden roof elements, traditional self-tapping screws or special fasteners that are resistant to corrosion and covered with a layer of galvanized steel are usually used.

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

An option is possible in which some of the individual elements of the rafter system will be assembled on the ground. It depends on the constructive solution and the project - is the roof with a bay window enough independent design, or it acts as a continuation of the roof of the house. In situations where the rafter frame for the end roof is assembled by separate trusses, then after lifting them to the roof, they need to be attached not only to the Mauerlat, but also to the ridge. They are usually attached to the latter using steel plates.

Now you can find on the Internet many photos of various hip roofs with a bay window, get detailed information about the rafters for any of them and read a large number 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 box of the house (11x13.5 m) must be covered with a gable hip roof and the bay window overlap is provided with a hipped roof. A bay window is located on the side of the end wall.

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

Installing Mauerlat

First, you need to install the Mauerlat and the bed. It is made from a bar with a section of 200x200 mm.

Installing the Mauerlat and the bed

Mauerlat is installed along the perimeter of the box, and lay along interior walls... Between the armopoyas 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 rigidly fix the Mauerlat and lie to the armored belt.

Installation of the main beams of the hip roof

The main roof beams are installed with a section of 100x200 mm. On the side of the bay window, a beam from a bar of 200x200 mm is installed. It is necessary to support the hips from the side of the bay window.

Installation of bay window beams

Bay window beams are installed.

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

Roof eaves filing

Eaves filing

Installation of support frames and hip roof truss system

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

Installing the base frame

At the top there is a ridge run made of a board with a section of 50x200 mm. It must be said that the roof can be installed both elementwise and complex installation.

When a truss is assembled, which is then installed in a 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.

There is also a ridge girder and strut on the bay window side, and the center post of the bay window has a centering core on which all the bay window rafters will converge.

Ridge run from the bay window

This centering element has a width of 30 cm and a height of approximately 50 cm. It is very important to provide this element as part of the roof, as it greatly facilitates installation.

In the next step, the 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 least effort.

The next step is to install corner rafters - two on one and two on the other side. Further, the wives are installed. Rafters and rafters on the main slopes have a cross section of 50x200 mm. Section of the hip cuffs 50x150 mm. These slopes are steep snow will not be here therefore there is no need to provide for particularly massive structures.

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

Setting hip roof stiffness ties

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

Setting Roof Stiffness Bracing

Roof stiffness ties

Inside this farm there is an opening measuring about 2.2x5.5 m and this is quite enough for 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 processed with fire 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 battened, then a valley bar is installed to mate the main roof and the bay window roof.
