How to correctly calculate the bias of the roof?

The purpose of the roof is to protect against natural phenomena - wind, rain, snow, heat or frost. The roof can be both with a minimal inclination and have a great value of the slope. In order that the roof is harmoniously combined with the construction and at the same time with this perfectly performed its functions to know how correctly.

The calculations take into account the following factors.

The first thing that takes into account is the region where the house was built. Each region has its own characteristics. The amount of precipitation and wind power can be very different and, accordingly, influence the optimal one. For example, the larger the snow falls in the region, the more lowered the roof should be.

On such roofs, the snow does not accumulate in large quantities and does not waste all the roofing system, and the water goes quickly, not causing and without destroying the roofing material, therefore, the load on the waterproofing will be less. For regions where strong winds are often blowing, it makes sense to install a roof with a minimum angle of inclination.

Thus, the impact of wind will be smaller compared to the type of roof described above. The whole design will be more reliable and less likely to break the roofing coating with a strong impact rush.

Factor: type of material

Each type of material has its own technical characteristics and features of both the installation and operational moments. Therefore, it is necessary to specify to what angle in degrees or percentages is calculated by this material.

With a small roof slope to 10 o or in percent, up to 15%, rolled cocelers are used, such as rubberoid, etc., but you need to know - the less the slope, the more coating layers need to be laid (from 2 to 4 layers). With a bias of more than 20% (12 o) use metal tiles and ceramic tiles, professional flooring, slate.

What is affected by the angle of the roof?

With an increase in the angle of the roof of the roof, the following questions and nuances may arise:

• The greater the bias, the greater the area of \u200b\u200bthe roof and the more it is necessary for the roof materials. Therefore, the calculation of the declaration of the roof is economic, it can be regulated with it and calculate the necessary costs, selecting the optimal version of the final type of roof depending on the material possibilities.
• The load on large scope roofs with severe wind gusts is enhanced several times. For example, if you compare the roof with an angle of 11 o and 45 o, the effect on the second will be about 5 times more. If nevertheless, in the wind regions, install such a roof, then it is necessary to strengthen the entire design - the soling and the crate system. At the same time use the beams of a larger cross section and do less step. This design may be unprofitable from a material point of view and from the increasing weight of the construction, which can negatively affect the foundation and carrier walls. Therefore, better depending on natural conditions.
• With a sufficiently large angle of inclination of the roof of more than 60 o, you can even not consider the weight of snow, the effects of melt water and rain - the sediments will immediately roll from the surface of roofing materials, without leading to the stagnation. But here too, there is a feature. Firstly, the material must correspond to such a large corner. Secondly, the shap must be with a smaller step for a more reliable fixation of the roofing material.

Small slope: pros and cons

The roofs with a small percentage of slope also have its advantages and cons:

• In winter, it is necessary to organize regular cleaning from snow. Otherwise, with a large accumulation of snow and ice, the roof can be saved under the total weight or from it will go "avalanches".
• We necessarily require the envisaged and installed water removal systems.
• Even if the thawed and rainwater are installed and operate in normal mode, all the slots and joints of the roofing sheets must be processed by a sealant, the waterproofing layer should be more denser with a decrease in the angle of inclination.

Determination of the angle of inclination of the roof

With the development of IT technologies, computer programs have appeared that help in carrying out calculations and determining the optimal angle of inclination. To do this, you must enter the necessary data and you will automatically get the ready-made result.

Another way to contact a professional builder engineer. He will be able not only to make all the necessary counts, but also consult on building materials and organizational moments. By the way, this is the best option from all possible. But the services of the masters imply payment for their work.

Calculate the angle of the slope can be independently, but it requires attention and certain knowledge. For calculations, there is a formula for which one can determine either the height of the skate with the already installed corner of the slope, or the angle of the skate, knowing the height of the skate.

We will analyze on the example and calculate the required height of the skate. To do this, it is necessary to measure the width of the wall at home. The resulting value is reduced by 2 times and multiplied by the coefficient taken from the brady's coefficients table defined for each slope angle.

Thus, it is possible to calculate the height of the skate, knowing the angle of the slope, and on the contrary, knowing the height of the skate - find out the angle of the slope.

We conclude

In principle, there is nothing complicated here, but once again we remind you that specialist services include not only the necessary calculations of the geometric size of the building, calculations of the consumption of materials, but also professional advice on any issues that lie in the field of a particular specialist. Therefore, it is not worth neglecting their services.

In any activity, practical skills had an important role. So with the type of roofing and corners of its slope. You can always pay attention to neighboring houses, and then in the image and likeness to do in the same way. Of course, if the next roof reliably protects from all weather phenomena and at the same time has a flawless look - in this case it can serve as a good example.
