How is the roof calculated?

The construction of any structure or part of it, 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.

The main thing is to determine the material that will form the basis of overlap. Most often, as in the old days, and nowadays, 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 roofing from the metal, you will see that this is a rather costly option, and to use it or not is a private matter for everyone.

Often, in order to make the right measurements and determine the future 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 the same four-slope. If the structure of your roof is four-pitch, then when you decompose it into geometric figures, you will get 2 or 4 triangles and 2 trapezoids. Now we remember the school mathematics and set the area of each individual part of the roof according to the necessary formulas and quantities. After the final calculation, it is worth adding "extra centimeters" to them, which will go to eliminate gaps and cracks.

Calculating the roof area of a gable roof is made even 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 slopes. For people living in rainy or cold regions, steep roofs will be 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 has been noted earlier - an overlap. In order for the calculation of the roof, which you do previously, did not fail you, consider that allowances should be at least 10 centimeters for each floor element. Otherwise, you can not avoid leaks and wind blowing.

Now it is much clearer how to calculate the roof. It remains only to not lose with the material and rafters, on which the entire system will hold. Good luck with your construction endeavors.
