Roof Pitch Estimator

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. Use our roof pitch calculator to find the pitch of your roof. Enter any angle or fraction of angle to find pitch. Roof pitch roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.

In the uk the typical house has a pitch between 40 50 although 45 should be avoided. The pitch of the roof is the rise over a 12 inch run. 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.

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. This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. The roof pitch calculator is a convenient online tool you can use to quickly assess the pitch of your roof to determine the length of rafters you need. In the usa the range of standard pitches is anywhere between 4 12 and 9 12.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. It will use the current cost of wooden rafters based on the average price found at home improvement stores. Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25. There is no standard universal roof pitch.

A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. How roof pitch is calculated to accurately calculate the area of your roof you must first determine its slope or pitch. The roof pitch calculator calculates slope pitch angle and rafter lengths based on input of rise m and run r. Use the diagrams on this page as a reference when inputting rise and run and while interpreting the calculated results.

It is often compared to slope but is not exactly the same. For example a 4 12 pitch roof that is 100 square feet. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Roof pitch varies depending on culture climate style and available materials.

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.
