The construction of any structure or part thereof,whatever one may say, requires a preliminary calculation. As a rule, sketches of the future building are made on paper or in a specialized computer program, but the essence of this whole process remains the same - it is true to calculate the load and endurance, and also competently combine the used building materials. In this article, we will consider such a section of construction as the calculation of the roof, we learn some nuances that may arise in such a process, and we will understand whether it is really difficult to do this.
Mainly it is necessary to determine the material,which will form the basis of the overlap. Most often, as in the old days, and in our days, slate is used. However, materials such as tile, metal profile and ondulin are very popular. Also do not forget about the metal tile - this is the most durable of all the above options. It can last for a very long time, can not be influenced by both low and high temperatures and reliably protects against rain and snow. However, after calculating the roof of the metal, you will see that this is a rather costly option, and whether to use it or not is a private matter for everyone.
Often in order to make correct measurementsand decide on further work, people call professionals. In fact, each of us can do this. Calculation of the roof begins with the fact that it is necessary to determine what the structure of the roof: gable or a four-slope. If the structure of your roof is four-pitch, then when you decompose it into geometric shapes, you will get 2 or 4 triangles and 2 trapezoids. Now we remember the school mathematics and by the necessary formulas and sizes we set the area of each individual part of the roof. After the final calculations, it is worth adding "extra centimeters" to them, which will go to eliminate gaps and cracks.
The calculation of the roof area of the gable roof is doneeven easier. This structure consists of two rectangles, so it is only necessary to calculate the area of each of them and add the results. Do not forget also that it is worth buying material with a margin. If you build a house from scratch, then before you do the calculation of the roof, you need to determine the angle of the slope of the rays. For people living in rainy or cold regions, steep roofs are ideal, which will not allow moisture or snow to linger. If the house is built in the south, then you can afford to build a sloping roof with minimal costs for building materials.
Let's return now to that aspect which wasmarked earlier - overlap. In order to calculate the roof, which you do previously, did not disappoint you, consider that allowances should be at least 10 centimeters for each element of the ceiling. Otherwise, you can not avoid leaks and wind blowing.
Now it is much clearer how to do the calculationroofing. It remains only to not lose with the material and rafters, on which the entire system will hold. Good luck with your construction endeavors.
