Construction of an exact science, so during the construction of a building is particularly important to correctly calculate the area of the roof.In our time, in order to facilitate this work, you can resort to the help of special electronic calculators, which are on some websites.But for the calculation in this case it turned out quite accurate, you need more and to have some idea of how to calculate the area of the roof.
This figure is important both from a practical and a theoretical point of view, if only because that the correct calculation of the area of the roof helps to understand how the roofing material to do this.And as a result, you do not have to buy the excess amount of a particular type of material.Also, if you know the exact area of the roof of his building can be optimally approach the selection of roofing material, taking into account its features.
To learn how to calculate the surface area of the roof, you will need to remember the course of high school mathematics.The first step is to take the form of a roof top, i.e. its projection.However, it must be remembered that such a projection is constructed at an angle, so at this stage would have further to remember the formulas of geometry.
If the roof of your building is not exactly a simple form, in this case, experts advise to divide it into simple geometric shapes.Most often in such a case the roof is broken into trapezoids, and triangles or rectangles.How to calculate the surface area of the roof in the event of a difficult shape it?
To do this, calculate the area of simple shapes, which you pitched roof, and these estimates are adjusted to reflect the angle of each such figure.Simply put, all the values are multiplied by the cosine of the space angle to the ground.All the values obtained are added, resulting in the whole area of the roof of your building.
How to calculate the area of the roof of his building and still get the most accurate results?To do this, the calculation must be remembered that the desired area is not in the parameters of the building, and on the eaves of simple shapes that are broken roof.If this does not take into account that in the end you can get the value of the area, which is not true, as a result of the material for the roof may not be enough.
also need to know that the various roofing materials have their own peculiarities of installation.Therefore, after the calculation of the area of the roof to the figures need to add another 20% in case of possible waste and some of the complexity of the roof structure.
Experience shows that approximately 7% of the roofing material goes to waste.And since most of the roof mounted lap, then that figure is added about 10%.To verify the correctness of its calculations, you can resort to the help of the electronic calculator.However, his services should apply only to verify the results, how to calculate the surface area of the roof alone can be more accurate.
