In this article you will learn about what a roof gable is and how it is constructed correctly. Below is a detailed description of the installation technologies of various finishing materials and load-bearing structures, the choice of components and the features of their use are described in detail. In addition to all this, you will be able to familiarize yourself with the requirements for the gable walls of residential buildings. After reading the text, you will not have any difficulties ordering construction work to erect the gable of your house.

Pediment design options
The pediment is a section of the wall that is limited from below by the ceiling, and from above by the planes of the roof slopes. Any gable, broken or single-pitch structure has it. Also, the presence of such a component is typical for a Danish roof. Pediments are used as the final element of many architectural structures. So any portico or portal is simply unthinkable without it. This design is also needed to decorate window and door frames. Since antiquity, the pediments have been covered with projections of the cornice slab.
Depending on the presence of different components, pediments can be simple or complex. The second option, unlike the first, involves the use of vertical braces as supports. In addition, in a complex structure, the cornices and rods end before reaching the central part of the wall.

The pediment is erected only in the vertical direction and can be either triangular or trapezoidal in shape, and sometimes even round and polygonal.
The gable wall limits the attic or attic space. The difference between them is that the first is residential, and the second is technical. The type of structure is designed based on the characteristics of its operation. For example, in the case of constructing a cold roof, a layer of thermal insulation must be laid between the outer and inner walls. To build an attic, the insulation must be located under the sheathing units.
By the way, in professional terminology, pediments are understood as the upper parts of load-bearing walls, made of stone, brick or other block materials. Wooden structures are called gables, and roofs using them are called gables.

Low-rise private construction combines both categories into one class of pediments. Despite the differences in design, largely similar technologies and materials are used for their construction.
There are two types of arrangement of gables:
- The first involves the construction of a frame consisting of racks, struts and braces , which is then sheathed with various coatings. This method is distinguished by its simplicity and lower cost. Due to the optimal price-quality ratio, this is the most common method of gable design in civil engineering. Using this technology, lightweight roofs are often erected for technical buildings.
- The second option for arranging a pediment is to cover a vertical wall from foam block, brick or any other building material. This method is characterized by increased complexity of execution and requires an increase in the budget for construction work. This technology is most often used during repairs or reconstruction. This method is distinguished by its external sophistication and high aesthetic qualities, so it is often used for decorative decoration of the walls of buildings. At the same time, houses are mostly sheathed from cheap materials.
The most common way to cover gables is to use vinyl siding. Source saw-wood.ru
Moisture-resistant plywood and plasterboard for exterior use are often used to decorate walls. But these materials must be painted and varnished after installation. In addition to them, polymer panels, corrugated sheets and polycarbonate sheets are also used. But the most common and profitable options are edged boards and polyvinyl chloride siding.
Insulation of gable wall
Insulating a gable wall is important when planning to use the attic for housing or for long-term stays for other purposes - a workshop, an office, etc.
The wooden and frame types themselves are good heat insulators, and the frame type already has a layer of insulation inside the sandwich.
Two methods of insulation are used - from the inside and from the outside . From the point of view of convenience and safety of work, insulation from the inside is preferable.
But from the point of view of physics, it will be more effective to carry out insulation from the outside , since in this case the dew point is moved outside the wall and moisture has the opportunity to evaporate into the atmosphere, and not inside the house or the insulating layer.
There are a lot of insulation materials that work well in such conditions:
- Glass wool;
- Minvata;
- Styrofoam;
- Penoplex.
These and similar materials successfully perform their task. Siding or other sheathing materials can be used for exterior cladding.
ATTENTION!
The pediment of the building, being a support for the rafter system , at the same time partially increases the load on it due to the influence of wind. Therefore, its construction must be carried out with an understanding of all loads and ways to compensate for them , otherwise there will be excessive pressure on the rafter system, which can lead to deformations of the roof.
You can read in detail about the calculation of the rafter system here.
All work must be carried out after consultation with experienced builders, and structural elements must have a safety margin.
Frame gable wall cladding
If the masonry of the triangular end of the wall consists of brick or other block materials, then the sheathing of timber or boards is erected quickly, is easy to implement and does not require significant costs. This is due to the ease with which wood is processed, which has a positive effect on the payment for the services of a construction company. A timber frame also weighs quite little compared to brickwork. Thanks to this, it does not create additional load on the floors. And in general, the pediment allows you to reduce the weight of the rafter system, while increasing its support area.
This is what the wooden frame of a gable roof looks like Source orchardo.ru
Any pediment made of wood is constructed using frame technology. This means that first a frame is erected, and after that timber, edged or tongue-and-groove boards, and also shingles or any other finishing material are sewn onto it. Designers also often calculate the structure so that the gable racks serve as a support for the sheathing for roofing made of corrugated sheets, metal tiles or other sheet materials.
Lumber gable walls can be built over brick or block walls, over log slings or wood frames. The pitch between the support beams is calculated based on the wind strength characteristic of the area. The load-bearing capacity of the floors is also taken into account. Most often, the distance between the posts is in the range from 0.6 to 1 m. The frame elements should be placed directly above the wall studs themselves.
It is necessary to pay attention that the cornice slab must protrude sufficiently. Source delabuga.ru
Roofs with a frame covered with boards or timber are most typical for buildings of the Canadian type. They quite effectively complement any masonry or log house. In addition, the rafter system receives additional support, and the lightness of the entire structure makes it possible not to strengthen the load-bearing walls. Therefore, finishing the pediment of a private house in this way is the most popular in our country.

What rules should you follow when arranging a pediment?
A beautiful and correct pediment is the key to successful construction and good appearance Source masterles-ekb.ru
First, let's understand some construction terms:
A cantilever beam is a type of structural truss designed to support any protruding parts. In our case, this is a cornice overhang.
The gable support is a vertical post on which the sheathing is attached for further cladding with lumber.
The top frame of a building is a beam or board connecting the protruding ends of beams and rafters. It is needed in order to give the structure rigidity and additional area for attaching the sheathing.
The support for the gable wall can be made in the form of a mauerlat, top trim or floor beam. The type of this element depends on the material from which the load-bearing walls of the building are made. If the overhangs of the structure protrude by more than 30 cm, then they are strengthened by installing additional short beams.
Here the gable wall rests on the mauerlat and has overhangs with cantilever beams Source supersadovnik.ru
If the offset is less than 300 mm, then its design includes a board with a cross-section of more than 19 cm, which is attached to the beams with nails or self-tapping screws. Also, such an overhang includes a frontal board, fixed on the outlets of the end beams and on the cornice trim, as well as beams connecting these two boards. When the release is less than 30 cm, you can use the outer rafter as the top wall trim.
Another very important point: when arranging an extension of less than 300 mm, the sheathing must reach the upper edge of the rafters, and when installing more than 300 mm, it must reach the lower end of the cantilever beams. Moreover, in the second case, a strapping beam of the same cross-section as the gable posts is used. But it must be lower than the rafters, because the cantilever beams rest on it.
This is what cantilever beams look like without strapping beams Source tvoya-banya.ru

During the design and construction of the pediment, the following rules included in the list of SP 31-105-2002 must be observed:
- The installation step of the gable racks must be selected so that it is equal to the distance between the supports of the load-bearing wall. And they should be located one above the other. They must be attached to the top trim of the frame structure.
- The spacing of gable posts on a brick or block stack must meet wind resistance requirements for the region. It can be located in the range of values from 1 meter to 60 centimeters.
- The distance between supports for warm roofs is determined based on the width of the slab or layer of thermal insulation, which must be laid between the gable posts.
- If insulation is used to create a pediment, then its outer side should be covered with a layer of waterproofing , and the inside should definitely be covered with a vapor barrier film or membrane.
- To create the top trim of the eaves overhang, protruding less than 30 cm, extreme rafters are used . To increase the reliability of the roof, they should be made double.
- If the gables are connected to wide overhangs, then their framing should consist of a special beam . It is installed slightly below the rafter legs. It is moved down so that it is at the level of the bottom edge of the row of cantilever rafters.
- Pediments with an overhang, the width of which is less than 300 mm, are sheathed close to the outer edge of the rafter legs.
- The cladding of a pediment with a wide overhang is made close to the surface of the outer outline of the bar intended for fastening the cladding .
This is what a correct gable frame with a wide overhang looks like. Source wahonev.hirupeza.ru.net
To fix all the finishing elements of the roof and gables, nails and screws are most often used. To strengthen the components and critical parts of the structure, staples or metal plates, as well as building corners, are used.
It is very important that the arrangement of the pediment complies with all the rules of frame construction. Thus, the first requirement for these structures is the presence of a layer of vapor barrier material on the side of the roof space. After this there should be insulation, the outer side of which requires the presence of waterproofing.
According to the technology, thermal insulation boards should be placed between the sheathing, sheathing or frame elements that play the role of enclosing structures. But it is important that the layer of insulation fills the entire allotted space in length and width. Otherwise, air gaps will appear between adjacent structural elements. This will significantly worsen the characteristics of the attic and attic and make them ventilated.

Technology of work on the arrangement of the pediment
The gable of a building can be erected both before and after installing the sheathing and roofing. Most often this is done before work on the roof is carried out. This option has its advantages:
- It is more convenient to install all the elements and components of the rafter system on rigid gable walls.
- This solution also allows you to reduce the windage of the entire roofing pie, so as not to allow the wind to undermine it from below.
- In addition, timely construction of gables allows you to give geometric parameters to the entire roof.
- Creating a gable wall before starting roofing work makes it possible to use the component parts without first trying on the trim. All excess parts are simply sawed off after the wall frame is completely sewn up.
But there is one more plus: the equipped pediment increases the safety of roofing work.
Arrangement of the gable before roofing work has a lot of advantages Source drevcenter.ru
Proper construction of a pediment involves complete cladding of the structure frame. But in order for the structure to be reliable and stable, it is necessary to have sheathing. It can be made of a metal profile or angle, but most often a beam with a section of 50*50 or 40*50 is used. Its ease of processing and affordable price speak in its favor. The timber is also well compatible with any lumber for wall cladding.
If metal parts are used to arrange the sheathing, then you should definitely take into account the differences in the thermal conductivity of the materials. Between the steel sheathing and the wooden upholstery, some kind of waterproofing layer, like roofing felt or burlap, will simply be necessary. This is due to the fact that the difference in the thermal engineering of materials leads to the obligatory appearance of condensation.

How to calculate area and dimensions
The need to calculate the area of the pediment may arise when determining the amount of building or finishing materials for its construction.
The calculation of the area and size of the pediment is based on geometry and is based on the house design data.
We can find out how to calculate the area of the pediment using the formula for the area of a triangle - the product of the base and the height divided in half , where the base is the width of the end wall of the house, the height is the height of the roof from the ceiling to the ridge.
If the height is unknown, but the width of the wall and the angle of inclination of the slopes are available, then the height can be determined by multiplying the width of the end (gable) wall by the tangent of the inclination angle, determined from the Bradis tables. Most often, the height of the future roof is known in advance, so complex calculations are rarely necessary.
IMPORTANT!
When designing a house, it is important to calculate the load on the foundation , since the weight of brick or cinder block gables makes serious adjustments to the distribution of the load. Therefore, all dimensions are most often calculated at the project development stage.

If you are planning to build a house with a pediment, then you will be interested in this video about the features of siding:
When arranging the pediment of an attic roof, the board is not drawn out with an accuracy of millimeters: the excess section should simply be sawed off after installation in its place. Any openings and openings in the wall can be cut after the structure has been arranged. But still, most craftsmen are confident that it is better to do this first, before installing the sheathing. If the roof structure is of an insulated type, then the door frames should be inserted before the pediment frame is sealed.
To prevent atmospheric moisture from getting into the joints of the sheathing boards, they are spiked on both sides. In this case, the outer tenon should be turned down. The best protection from rain is provided by the horizontal direction of the cladding. If lining or tongue and groove boards are used, the middle tenon should be turned upward.

How to make a canopy on a pediment yourself: a quick guide
In order to provide complete protection against water ingress, the best option would be to organize a canopy with a slope width of at least 60 cm. It is desirable that the design of the product is not too conspicuous and does not spoil the overall appearance of the building.
As for the overall roof slopes, it makes no sense to make a cantilever canopy structure for them. A much more rational solution would be to install a canopy with outriggers. Often they try to ensure that the width of the canopy is no less than the width of the foundation blind area.
You can finish the cornice using corrugated sheets
The easiest option is to form a canopy on miniature wooden rafter supports, which in their structure resemble fillies. In this case, it is necessary to make and secure the supporting structure of the canopy before the pediment is closed with lathing or siding.
As for the design of the pediment canopy, it should be characterized by rigidity and at the same time lightness. To do this, you need to sew several sheathing bars onto the rafter mini-supports. Ideally, you can design a canopy with a continuous lining of the slope with a lath or clapboard. In such a case, it is recommended to form the slope from the remains of soft roofing material and sew it up with metal tiles or slate.
After the flooring has been laid, care should be taken to protect the area where the roofing material of the canopy meets the wall.
Helpful advice! The area where the canopy adjoins can be easily designed in the form of gutters of the drainage system. Thanks to this, it is possible to minimize the amount of water that flows onto the canopy along the surface of the gable.
The width of the ramp must be at least 60 cm
The simplest solution is to seal the joint between the metal and the wall material using sealant or by gluing roofing felt tape. Then you need to form and sew a narrow strip of metal cornice over the sealed layer.
Covering the gable using siding
PVC siding was originally designed specifically for arranging gable walls and lightening the load on them. The material is characterized by high resistance to any weather conditions and precipitation. Siding is installed quite quickly and easily.
There is a huge selection of different options for finishing siding for gables. It can be made in the form of planks, logs, bricks and stone tiles. The panels are very firmly and conveniently joined together, which contributes to an even pattern without tears or displacements. Also, finishing a gable wall with siding does not take much time and does not require a large amount of labor.
Many professionals believe that polyvinyl chloride siding combines all the best technical and technological qualities of finishing materials. After all, it is light and at the same time durable, fits perfectly, is not expensive, and its service life can be up to 40 years. Another plus is that siding can be used for reconstruction and renovation of old buildings. In addition, vinyl siding is often used to completely finish a house, not just the gable.

The panels are connected to each other with strong latches, which are located on the long sides of the segments. The siding is fixed to the frame with nails or self-tapping screws.
In order to connect all the components at the corners, additional fittings are used in the form of connecting, starting or finishing profiles, moldings, corner locks and near-window strips. When purchasing connectors, you should definitely pay attention to the fact that they are compatible with this type of siding.
A special flange with elongated holes for attachment to the sheathing is used as a starting strip for vinyl sheathing. Sometimes it has an additional bend on top, which is needed in order to give rigidity to the entire system.
Thanks to special locks, seams on the surface of the PVC sheathing are completely invisible Source grandline.ru
The front part of the siding panel is called the form factor. It imitates some material. There are also models of this material that have a look characteristic of several coatings at once. Most often, their components are wider.
Briefly about the main thing
The finishing of the pediment largely depends on its shape, whether it needs to be insulated, and what its frame is made of. Sheathing is always required for frame gables, while permanent gables made of brick, blocks or timber can be left in their original form. A variety of materials are used for cladding - boards, wooden lining, all types of siding, corrugated sheets, plywood and even plastic panels and polycarbonate. It is attached to the sheathing, the design of which is selected taking into account the selected finishing material. To get a beautiful result, it is advisable to use various additional elements - profiles that allow you to neatly connect the panels and hide their sections under the slopes.

This video was shot specifically so that you have an idea about installing the panels on the frame:
Two ways to install PVC panels
In order to cut slabs of the desired shape, special templates are used, which are made based on the angles of inclination of the roof and its shape. The material for them can be thick paper or cardboard.
This picture shows the most convenient way to cut siding panels Source yandex.kz
When cutting panels according to templates, always maintain the temperature reserve, and do not adjust them flush with the edges of the pediment. At the very top row of panels, the entire nail strip is cut off, and holes are drilled at the top of the slab for installation.
The point for drilling is determined after applying the segment to the seat. But the hole should be located no closer than 3cm from the cut edge of the plate.
The installation of the panels itself proceeds in a vertical direction from bottom to top. Installation begins with fixing the starting profile and continues with the systematic fixation of slabs and connecting elements.
Preliminary calculations ↑
When constructing the pediment of a house made of timber, first of all, it is taken into account that it is constantly exposed to loads created by the wind. Any mistake made in the calculations can have serious consequences, including the collapse of the roof and even walls. To calculate the amount of material, the area of the structure plays an important role. In addition to those already noted, the following factors must be taken into account:
- features of the region,
- type of construction,
- resistance of the house to intense wind currents,
- sheathing,
- location height.
A pediment made of profiled timber has its own characteristic features, which play an important role in the calculation and construction.
For example, it should be taken into account that this material is far from perfectly smooth, so gaps of different sizes form on the surface of the structure. They are filled with tow. In a similar way, the cracks in the pediment made of laminated veneer lumber are also caulked. Gaps are filled regardless of the type of cladding chosen.
Important!
When performing a preliminary calculation of such a gable wall, one more very important point must also be taken into account - the shrinkage of its triangle and the frame, which occurs during at least the first two years.
In one-and-a-half-story houses, gables are cut from 150x150 timber. As for internal partitions, others are used for them - 100 by 150. Their height can reach 2.5 m. However, many builders adhere to the so-called gold standard for how to make a roof: the pediment for buildings optimally has a height of 150 cm, otherwise speaking, has 10 crowns.
Video description
The video contains a detailed description of the features of finishing work using vinyl siding:
Installing vertical siding on the roof gable requires additional labor costs, because with this installation method it is more difficult to achieve an ideal result.
Vertical installation of vinyl siding should be done in the following order:
- Corner strips are fixed along the edges of the gable wall .
- A plumb line is lowered from the top of the rafter system, necessary to indicate the central axis .
- is installed along this line .
- With a predetermined step other plates are attached parallel to the central one.
- the installation of panels begins , with the first segments installed in the corners of the structure.
The end result should be a vertical cladding like this Source bg.decoratex.biz
conclusions
As you can see, every home craftsman can build a high-quality pediment, provided that the instructions are followed. Professional assistance will be required when performing the end part of the roof from logs and beams. If all installation conditions are met, you can build a high-quality and durable structure.

Architectural forms
Most of us are more familiar with triangular or pentagonal pediments, but these are not all the forms inherent in the under-roof part of the wall. Architects also create structures of the following type:
- keeled. Created in the likeness of a ship's keel. Despite all the beauty and grace, they are practically not used in modern construction, but belong to ancient architecture and in some places have still been preserved to this day;
- semicircular. These pediments are also practically never found in modern construction, since their installation is very complicated;
- trapezoidal. As the name implies, they are shaped like a trapezoid and are installed during the construction of half-hip roofs;
- triangular. The most common gables. In the case of a symmetrical roof, they will be equilateral;
- interrupted. The cornice of such sections of the wall is interrupted by a window opening;
- archery The shape resembles a semi-oval of a stretched bow. If the steepness of the bend is increased, they become semicircular;
- stepped. There are steps on the sides of such gables, and the roof is installed here without installing front overhangs.
What does a gable roof truss system consist of?
In appearance, the design of such a roof is not complicated, but in fact, under the roof lies a rather complex system of timber and boards. It consists of main components:
- Mauerlat. It is responsible for distributing the load on the load-bearing walls of the house. During its construction, timber is used (its cross-section should be square and dimensions 100x100 or 150x150 mm). The mauerlat is placed around the perimeter of the building, and it is best to choose lumber from coniferous wood for it. The latter does not deform over time.
- The rafter leg is a board that is located at an angle to the Mauerlat and helps to evenly transfer the load to it. The heavier the roofing material, the more often it is necessary to place rafters (usually their spacing is from 60 to 120 cm).
- The ridge is the connection point between the roof slopes. The rafter legs converge on it.
- On the continuation of the rafters, if they are short, fillies are installed. This structural element is used only if the rafters cannot form an overhang. At the same time, the use of fillies greatly facilitates the installation of rafters.
- Overhangs are responsible for removing precipitation from the walls (so that they do not get wet during rain and do not collapse prematurely). According to the standards, the overhang should protrude 40 cm from the wall.
- Beam - a beam laid to distribute the load from the racks. The slopes converge above the bed, forming an angle.
- The posts connect the skate and the bench. Thanks to them, the load from the erected roof is evenly distributed on the internal walls of the building.
- An additional structural element for distributing loads over large spans is struts. For strength, they are connected with puffs. A structure made of struts and tie rods is called a truss.
- The final element of any roof is the sheathing. It is performed perpendicular to the rafters and is necessary in order to hold the roofing pie on itself (this is the name given to layers of insulation materials and tiles).
In order to build a rafter system and not make mistakes, before performing work you need to watch a detailed video about installing a gable roof. You will also need to draw up a detailed drawing, which will take into account the dimensions of your building and the selected roof parameters, for example, the angle of inclination.
Gable roof rafter system: device, do-it-yourself installation
The gable roof is very popular due to its simple installation, high strength and versatility. It is suitable for installing any type of roof and fits into almost any home design. In this article we will talk about how to assemble a rafter system for a gable roof. This information will be useful both for those who are going to work with their own hands and for those who want to supervise the work of a team of roofers.
The main elements of a gable rafter system
- Mauerlat. Distributes the load from the roof to the walls of the building. Made from durable and rot-resistant wood: pine, larch, oak. The standard section is 100*100 or 150*150 mm.
- Rafter legs. Installed on a mauerlat or ceiling crown. Hanging rafter legs are mounted on additional beams.
- Puffs. Used to connect rafter legs and enhance their rigidity.
- Ridge purlins are supports for the future ridge. They are installed at the junction of the upper part of the rafters.
- Side purlins (optional). They provide additional rigidity to trusses and strengthen large spans.
- Rafter posts are vertical beams. The installation location depends on the width of the span (in the center or in the center and on the sides).
- Longitudinal and diagonal struts are supports for racks. Necessary for proper distribution of wind and snow loads.
- Beds - supports for racks and fixation of struts.
- The sheathing is the basis for installing the roofing covering. It is installed perpendicular to the rafters.
The photo shows the main types of gable roof rafter systems. Some of them can be assembled with your own hands, while others will require professional calculations and installation.
Installation stages
When installing the truss structure, you can be guided by the following diagram:
Mauerlat installation
The Mauerlat beam is laid along the wall to which the rafters will be attached. In houses made of porous materials (foam concrete, brick), the Mauerlat must be installed along its entire length. In other cases, it is enough to lay the timber between the rafter legs. Anchor bolts, wooden dowels, metal brackets, studs or reinforcement, hinge fasteners or wire are used as fastenings.
Installation of rafter legs
Typically, rafter pairs are assembled on the ground and then raised to the roof. If the rafters are heavy, installation is carried out at the top. Before starting work, it is better to draw a diagram and make markings on wooden blanks - this way the rafter pairs will be absolutely identical.
Installation of the ridge unit
Depending on the complexity of the scheme, different fastening technologies can be used here: with or without rafter beams, overlay or notch method, fixation with special fasteners. The choice depends on the expected load and type of roofing.
When to build a gable - before or after building a roof?
For materials like brick, cinder block, etc. the most successful option is to build a gable wall before erecting the roof. Working with such materials in a cramped attic is difficult and causes a lot of inconvenience.
This situation may arise if it is necessary to quickly protect the building from rain, or in the absence of a clear plan for constructing the roof: sometimes the angle of inclination of the slopes is determined by eye and the selection criteria become purely aesthetic preferences of the owner.
This option has its advantages: the pediment is immediately connected to the rafter system and has support, while the pediment, which is erected first, is a section of the wall that is not reinforced by any means and needs support in case of strong winds.
Most of the decorations on the pediments play the role of an additional reinforcing element, which, along with the decorative function, performs mechanical reinforcement. The final choice of the order of construction of the rafter system and the pediment is determined mainly by the materials used for the pediment and the circumstances of construction - weather conditions, the urgent need for interior decoration, etc.
The opinions of experts on this issue differ diametrically - some argue that a finished pediment is needed first, others clearly advise building the roof first. Therefore, we can definitely consider both options to be equivalent.

The procedure for installing gables
Additional recommendations
If there is an attic under the roof, then the roof and gables will need to be insulated. There is no need to carry out any thermal insulation measures with brickwork and logs (beams). These are full-fledged walls that will perfectly withstand outdoor temperatures. But the frame variety will have to be insulated. To do this, insulation must be laid between two skins (inner and outer). You can use any, the main thing is to take protective measures to install vapor and waterproofing using special membranes.
What is a gable roof?
People choose such structures because of the savings on materials and ease of construction. A gable roof consists of two rectangles that are inclined towards each other (connected to each other on one side). The opposite sides of the joint are adjacent to the supporting walls of the building.
The advantages of gable structures are undeniable:
- ease of construction;
- saving materials;
- rare cases of leaks (the structure is monolithic and they can only occur if the joints are installed incorrectly or if the gable cladding is partially missing);
- their repairs are carried out on their own;
- high strength and resistance to normal wear;
- the possibility of using the attic as additional living space (if you choose a roof angle that will allow you to stand under it at full height, taking into account thermal insulation and ventilation).
When preparing for the construction of this type of roof, it is necessary to understand what parts the rafter system consists of, and also to provide for the laying of insulation and insulation from moisture and steam.
