House of red brick with a roof poluvalmovaya
Advantages and disadvantages of poluvalmovaya roof: photos of beautiful homes
What distinguishes poluvalmovaya gambrel roof on? In gambrel roof, two large slope have a trapezoid shape, but smaller stingrays - triangle shape. The roof poluvalmovaya things work a little differently, and the slope becomes a broken line shape.
The design of a sloping roof is largely dependent on the shape of the house, the presence or absence of residential premises attic type roofing material, which is covered with the surface and even climate peculiarities region.
And the crucial role it plays in creating a climate of construction, because in regions with snowy winters rainfall will be particularly hard to build up on the ramp surface, forming a kind of "snow cap". Therefore, for such a locality more relevant roof with a steep slope and minimal overhangs. If snow drifts - irrelevant problem, then it is valid and the minimum angle of inclination.

Among the advantages of the roof poluvalmovaya release:
- availability of additional space, which can be used as residential or loft;
- aesthetic appearance, with an unusual design house by creating a design of the original form;
- reliable protection at home from the effects of weather: snow, rain, strong wind.
Useful advice!In order to increase the usable area of the attic, you can use a design with different angles of inclination of the ramp.
Among the shortcomings poluvalmovaya crumbles worth noting:
- the presence of certain difficulties in the construction: a plurality of ribs, struts and stops erection truss system makes a long and laborious process;
Residential house, the roof is covered keramocherepitsey
- in the process of building a fairly complex design is used not only to a greater amount of force, but also materials;
- process is laying the roof covering acquires also some difficulty.
But despite its shortcomings, the house with the roof poluvalmovaya look unique. Difficulties and costs are worth it to make the roof of the original and memorable appearance. If you are not afraid of complicated installation of roof system, you can safely get to work. Among the photos of private houses, poluvalmovaya roofs are fairly common, so choose the desired option will be easy.
Roof poluvalmovaya roof
Under mansard roof is meant a structure which has two peaks in the form of truncated triangles. If the house has a square shape, the pyramidal roof will. This type of roof has increased strength. On rectangular houses mansard roof has two triangular sides and two trapezoidal. Ramps are arranged under the same angle, allowing them to be mounted symmetrically axial beams.
For poluvalmovaya roofs with attic used roof of metal
How does the roof truss system poluvalmovaya: diagram and photo examples
Like any other roof structures, roof poluvalmovaya consists of a plurality of layers, which one after the other are superposed on each other. Among these components are:
- truss system, which serves as a base to hold all the elements;
- mauerlat - lower support beam for rafters;
- materials that provide thermal, hydro and vapor barrier of the roof;
- roofing, which provides mechanical protection.
Truss system itself also has a few constituent elements: skate, rafters, pillars, struts, lathing, and more. Each of these elements performs its function, providing additional roof rigidity and strength. This is especially important when creating poluvalmovaya mansard roof.
Driving device poluvalmovaya and roof truss system
Installation poluvalmovaya roof should start with laying mauerlat on the load-bearing walls of the house. For brick buildings set reinforced belt, which provides additional strength and evenly distributes the load. In step concreting inserted therein vertical studs, made of galvanized metal. Mauerlat secured to reinforcement by pushed on.

The length of the pins must be sufficient to provide a projection beam of 2-3 cm. fixing step at the same time should be 120 cm. The minimum diameter of reinforcement used for fixing bars is 10 mm.
Useful advice!Positioning studs worth so that they are between the rafters and not further complicate the work.
Mounting roof system on the supporting walls of the house
To protect the reinforced belt, it is covered by at least two layers of roofing felt and only then skewer beams on the studs. How to do this can be found in the drawings. Poluvalmovaya roof thanks to this stage, the more durable.
Select and install mauerlat - one of the most important stages of the preparatory work. The cross section of timber used for this purpose must have 150 × 150 mm, or at least 100 × 150 mm. All necessary holes drilled in the ground, after which the wood is treated by specialized antiseptic to protect from moisture and fungus development.
Roof truss system poluvalmovaya: mounting bases
Poluvalmovaya roof apparatus includes a mounting ridge trusses (as nakosnyh and diagonal) and fasteners, such as metal staples and special vrubok.
Scheme truss system using double boards for better fixation
Ideally, diagonal rafters should be a continuation of the ridge, which is at the top, as it were divided into two parts and is coming down to the corners of the house. By the diagonal rafters are attached and narozhniki that causes these elements to take care of all the main load and weight of the structure. That is why the use for the manufacture of double boards 50 × 150 mm, thereby providing a reinforced framework.
Due to this, the bearing capacity of rafters nakosnyh increases, which allows you to use long integers beams for very large roof. Further, for the diagonal and common rafters can be used the same board, which makes it possible to facilitate the operation.
Useful advice!Remaining space of the apex is better not to fill with foam. It will not be disrupted air circulation, and the probability of the ridge prognivaniya wooden significantly reduced.
Compound trusses with metal clips provides additional rigidity
When the phase of installation nakosnyh rafters finished, and all the elements securely fastened to mauerlat and a ridge, it's time to start the installation of ordinary rafters. The upper part, they will abut the skate and the bottom in mauerlat. Before you start, be sure to check out the available projects with poluvalmovaya rooftops.
Useful advice!The distance between the rafters must take into account the width of the heat-insulating material, which you will use.
In order to gain a sustainable design, at both ends of the rafters make cuttings. This makes it possible to fix the elements. As an additional fastening using metal staples and patch-corners. If the roof of the house very long, you definitely need to create additional stops in the form of braces. For backup diagonal truss trusses used farm.
Compound with methods mauerlat rafter foot
If the floor slab is made of reinforced concrete, all the props and racks we can rely directly on it. Otherwise, you must install the additional tightening joists, or roof structure will poluvalmovaya unreliable.
Useful advice!All wooden elements of the roof before installation necessarily be treated not only an antiseptic, protects the wood from moisture, but also liquid fire.
How do poluvalmovaya roof with his hands: the calculation of the number of rafters and step between them
In order to obtain reliable truss system, and over the years fully operational, before the beginning of work necessary to carry out calculations which will form the basis for assembly. As an example, you can use the photo poluvalmovaya gable roof with a width of 9 meters at home.
For trusses used size boards 50 to 150 mm
Step is called the distance between the rafter, and usually the rate for residential town houses varies the range of 0.6-1 m. It depends on many factors, so you need to make calculations based on your own individual indicators. To calculate the required amount of trusses using the following algorithm:
- Measure the length of the roof and divide the desired pitch coefficient between the elements.
- Then add to the result unit, resulting number rounded to the higher value. This will be the number of rafters, which is necessary for finishing a given length of the roof.
- If the entire length of the slope divided by the resulting integer, the result you will get the distance you need to adhere to the axes of rafters (this is a step rafters).
It is useful to know that although the ideal axis, and passing through the center of the rafters, practice tolerance, depending on the slope angle changes the surface of the roof of the future. This is clearly seen in the photo poluvalmovaya gable roof.
Before you begin, you need to calculate the exact number of beams used on the basis of the project
Consider as an example of such a calculation is: the length of the roof slope is 16 m In this case the pitch between the rafters will be 0.6 m From the above algorithm 16 ÷ 0,6 + 1 = 28 = 27.66... This means that for the slope length of 16 m, we need the 28 rafters.
Useful advice! Rafter pitch width depends on the angle of inclination of the roof. Thus, the greater the slope of the roof, the greater the pitch rafters should be kept. This is due to the fact that the load distribution on the steep slope is uneven and increasingly falls on the load-bearing walls.
Alternatively you can use to calculate a special online calculator, although much better if you there is a plan or drawing poluvalmovaya roof with his hands, because having a clear example of a lot easier to make calculations and work.
Drawing poluvalmovaya roof according to individual requirements
Installation poluvalmovaya roof: the final stages of construction
When all the wooden elements are stacked and secured, we can only worry about the heat, steam and waterproofing the roof. To do this, lathing is done, and the top is rolled out, the material selected.
It is difficult to say what material is best to give preference to, but definitely good vapor barrier issue fulfill its function aluminum foil. With the help of construction stapler foil is attached to the rafters so that the glossy side facing inwards, that is, into the attic space.
For thermal insulation is most often used synthetic wool (mineral or stone), which is sold in rolls or mats. Insulation laid in the spaces between the rafters and covered with a layer of waterproofing. Previously we used for this purpose roofing material, but today it was superseded by the diffusion membrane.
Fit between rafters insulation, most commonly used mineral wool
If the space under the roof ridge has not been patched, the natural ventilation will prevent mold and mildew to grow inside the "pie".
Of course, in matters assembly poluvalmovaya gable roof is hipped far superior due to a simple structure and lower costs for installation. But if we talk about the end result, then nothing can be compared with the complex beauty of a hipped roof. Photo poluvalmovaya hipped roof well show the whole beauty of this solution.
And with all this, the second option gives much more space to the attic equipment which will help build instructions, photos and video of the roof truss system poluvalmovaya provided in Internet.
The final stage will be the installation of waterproofing and roofing
The choice of roofing material for roofs poluvalmovaya
Considerable importance in the creation of beautiful and reliable roof is the choice of roofing material. Consider some of the most popular solutions, and how they meet the requirements.
The installation and operation of the process, the roof covering have to deal with a number of external factors, which have different effects on it. Among them: rain, strong wind, "snow cap", the impact of ultraviolet radiation and large temperature. To carry out the selection of a suitable material to be guided by these data.
asbestos-cement sheetsOr slate - an inexpensive and fairly durable roofing material. It has a number of advantages, such as fire safety, high resistance to temperature variations, corrosion resistance and the development of mold and fungi. Slate never rot and does not lose its appearance in the sun. For giving a more aesthetic appearance and improve Performance asbestos sheets can be painted.
Slate is sufficiently resistant roofing material
For poluvalmovaya roof, this material is not well suited for two reasons:
- It is an inexpensive coating will not look advantageous on such a complex structure;
- slate fairly brittle material and its precise cutting takes a lot of time and effort.
metal - it is also quite affordable material, but it is much more attractive. Long service life (up to 30 years with regard to the service) and excellent technical characteristics have made it a leader in its cover price category. The material is not afraid temperature changes or mechanical stress. A wide range of colors available on the market, allows you to choose a shade to suit all tastes.
The main plus metal - is its light weight and, accordingly, a small load on the truss system poluvalmovaya roof.
Metal - the best option in terms of price and quality
Among the shortcomings of this material can be isolated integrity of sheets for which the cutoff roof poluvalmovaya requires some skill and dexterity. And, of course, very low sound insulation. After all, we all know the sound of raindrops hitting the metal coating.
composite tiles - one of the types of metal, which is widely found on the market. It is worth a covering expensive, however, and has better technical characteristics. Among the shortcomings noted only heavy weight material.
flexible roof - ideal for poluvalmovaya roof. Shingles are sold in rolls and is easy enough to cut pieces to size. This makes it easy to make out areas with high architectural complexity. Among the technical characteristics can be identified:
- low weight material;
A convenient embodiment for roofing roof can assume poluvalmovaya flexible shingles
- fire resistance and water resistance;
- a huge range of color and style decisions;
- emergence of resistance to mildew and rot.
KeramocherepitsaIt is perhaps the most ancient of the proposed materials. The roof is laid from individual elements, which have been fired at very high temperature. This is an environmentally friendly material which is resistant to both high and low temperatures. Undoubtedly, this material has a very long life - up to 150 years.
Such coverage is excellent for the roof poluvalmovaya provided high strength and reliability truss system, as keramocherepitsa differs quite considerable weight.
Another feature of this material - the fragility of the individual elements. However, this is offset by ease of maintenance and the ability to replace every single detail.
The most durable roofing embodiment is keramocherepitsa
A wooden shingle coating or. Eco-friendly and a very nice option. Component elements - small plates of all sorts of wood - oak, beech, aspen and coniferous sorts.
Decking. Its popularity, this material is required a good performance, combined with an affordable price. The main advantage of such a roof - cost, but there are other advantages:
- low weight;
- ease of transport and stacking;
- long service life;
- resistance to corrosive damage;
- large selection of colors.
Galvanized profiled an affordable price and a good strength characteristics
However, as the metal, this material is quite noisy during rain and hail. Also, it can resist corrosion provided that mechanical damage due to improper transport and installation. Besides laying on poluvalmovaya roof sheeting as other sheet materials, it is complicated by the need to cut out the individual elements.
As we can see, creating poluvalmovaya roof with his hands, though not easy, but quite feasible task. Thinking through all the stages and gradually following the algorithm, you can give your home an original look, making it more comfortable and beautiful.
