Pitched Roof Slope Calculator

First convert the pitch to a slope.

Pitched roof slope calculator.

Given pitch and a horizontal area measurement multiply the horizontal area by a correction factor corresponding to pitch provided in the table below to determine the actual area of the roof to be used in the roofing material calculator. If your roof is pitched enter the length and width of the flat area covered by the roof. Enter any angle or fraction of angle to find pitch. You need to supply the following information.

Take your area result and multiply it by the pitch multiplier or slope correction factor found in the table above to arrive at the roof s surface area. Roof pitch calculator results explained slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run. To do this simply convert the rise and run as a fraction to a decimal form eg. Total height of building.

Various roof pitches need to be edited used and changed with a calculator to make sure that they are a logistical fit. To calculate the weight of snow on a roof use the first two sections of our snow load calculator. Now you re ready to price out the materials. Roof pitch calculator roof slope calculator 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.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Enter any pitch or fraction of pitch to find angle. Length and width of your roof. Rise run rise run slope.

You can enter these values in any units you d like including meters and feet. This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. To accurately calculate the area of your roof you must first determine its slope or pitch. For multi pitched roofs simply add the areas of all common pitches together by toggling layer visibility from the summed layer identified by the eye symbol at the left of the layers control.

Roof slope calculator example of use measure the run length it is the horizontal distance between the roof ridge and the wall of the building. This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Let s assume it is equal to 6 m.

Measure the rise 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.
