Roof Pitch Estimator

Roof pitch roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.

Roof pitch estimator.

The roof pitch calculator calculates slope pitch angle and rafter lengths based on input of rise m and run r. This online truss calculator will determine the all in cost of your truss based on key inputs related to the pitch width and overhang of your roof. In the usa the range of standard pitches is anywhere between 4 12 and 9 12. Roof pitch varies depending on culture climate style and available materials.

This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12. In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches. It is often compared to slope but is not exactly the same.

The pitch of the roof is the rise over a 12 inch run. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. Use our roof pitch calculator to find the pitch of your roof. It will use the current cost of wooden rafters based on the average price found at home improvement stores.

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. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. This gives us a 3d roof area of 1 625 sq ft. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.

Use the diagrams on this page as a reference when inputting rise and run and while interpreting the calculated results. Enter any pitch or fraction of pitch to find angle. Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area. Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25.

Enter any angle or fraction of angle to find pitch. How roof pitch is calculated to accurately calculate the area of your roof you must first determine its slope or pitch. After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.

There is no standard universal roof pitch.
