Assuming this is a hip roof we multiply this by 1 1 which gives us roughly 18 squares or 1 800 square feet of the roof surface. The roof pitch calculator calculates slope pitch angle and rafter lengths based on input of rise m and run r.

It will use the current cost of wooden rafters based on the average price found at home improvement stores. The pitch of the roof is the rise over a 12 inch run. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. In the uk the typical house has a pitch between 40 50 although 45 should be avoided.

Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area. Use the diagrams on this page as a reference when inputting rise and run and while interpreting the calculated results.

Enter any angle or fraction of angle to find pitch.
