Roof Pitch Estimator

Roof pitch varies depending on culture climate style and available materials.

Roof pitch estimator.

It is often compared to slope but is not exactly the same. This gives us a 3d roof area of 1 625 sq ft. For example a 4 12 pitch roof that is 100 square feet. 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 uk the typical house has a pitch between 40 50 although 45 should be avoided. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Use our roof pitch calculator to find the pitch of your roof. After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually.

It will use the current cost of wooden rafters based on the average price found at home improvement stores. 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. The roof pitch calculator calculates slope pitch angle and rafter lengths based on input of rise m and run r. 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.

The pitch of the roof is the rise over a 12 inch run. In the usa the range of standard pitches is anywhere between 4 12 and 9 12. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area.

Enter any pitch or fraction of pitch to find angle. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Enter any angle or fraction of angle to find pitch. Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25.

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. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. There is no standard universal roof pitch. This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.

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