## How does this roofing calculator work?

This is a useful home calculator that determines the roof pitch, the area of your house cover and the materials needed for the roof construction together with the total cost of the roofing materials.

The roofing calculator comprises of 2 tabs for the two measurements systems English (US) and Metric (SI). All you have to do is choose the desired tab, input the roof base, rise, length and the assumed cost per square feet of roof then the tool will do the work.

## Example calculation

Roof pitch data:

Width = 25 m

Rise = 6 m

Area and cost data:

Length = 40 m

Cost per square meter = 124 monetary units
