Roofing Calculator
The following tools estimate the area of a roof, as well as the amount of materials necessary to construct a roof of a given area. The "House Base Area" is the area of land that the house covers, and for more complex shapes, it can be estimated using the Area Calculator.

The estimated roof area is 260.8 square meters or 2,808 square feet or 311.9 square yards.
To have 10% buffer would require 31 roof squares.
Estimated price: $1,304.
By United States standard, the roof will need:
- 85 bundles of composition shingles (each bundle will cover ~33 ft²)
- 29 rolls of roll roofing (~36 in x 36 ft for each roll)
- 8 rolls of #15 felt (~36 in x 144 ft for each roll)
- 15 rolls of #30 felt (~36 in x 72 ft for each roll)
Roofing ceramic tiles do not have a standard size. Consult contractors to determine the amount needed.

The calculated area is only an estimation. In cases where a roof has a complex shape, measuring the dimensions and areas of each part of the roof will result in a more accurate measurement. The Area Calculator can be used to calculate the area of a variety of simple shapes.
