At construction there is always question of calculation of material. Building materials today not cheap and if you are going to get roofing material then it is important not to lose. Roof - business expensive. If roof broken, then it is necessary to consider all subtleties of its architecture and not to forget about skates and eaves. Therefore, it is better to use services of professionals.
It is required to you
- - tape measure;
- - project of roof;
- - calculator;
- - BRAAS program;
- - services of the professional.
Instruction
1. If you have decided to calculate amount of necessary material independently, then for a start decide on the choice of specific roofing material and learn its sizes. To calculate the area of the roof you need project roofs (if it is), tape measure, the calculator, to remember geometry course. Usually for calculation of the area the roof is divided into geometrical figures (for example, into rectangles, triangles or trapezes). Then make calculation of the area of each element separately.
2. For example, if you have conditionally separated roof into triangles, then calculation approximately such. Remember Pythagorean theorem. In advance make measurements of all necessary parameters by means of tape measure. Draw the approximate drawing. Let's say that the party and is the length of slope of your roof projections. The party is its height from the top point of slope of roof to the lower point. The party with is the length of slope of roof (real). Then we will calculate coefficient on formula - r/a (it is your coefficient). Further calculate the area of projection of roof (for this purpose increase length by width). Then increase the received digit by your coefficient (r/a). Here to you the approximate area because here slopes and possible windows are not considered. On the same formula you will be able to check approximately correctness of calculation of the area of roof if ask for the help professionals.
3. There is still way of calculation of roof area. For this purpose you need Internet access. You can download the special BRAAS program. With its help it is possible to calculate the area taking into account chimney, mansard and roof windows, slopes and skates. It is possible to choose any suitable geometry of roof in options. It is possible to calculate complete set for roof from tile and spare parts to it.
4. If you cannot independently make calculation, then address the professional (the company or the private trader). In case of the appeal to the company which is engaged in roof of roofs you will be able to use complex of services (calculation, delivery and mounting of roof).
