Pitched Roof Slope Calculator

After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually.

Pitched roof slope calculator.

Let s assume it is equal to 6 m. To find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the slope. First convert the pitch to a slope. This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.

Rise run rise run slope. Calculators will give you the right verdict back so that whatever you decide you are left with a roof pitch that you feel happy with. 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. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

Depending whether the roof area is measured horizontally possibly from a drawing or photograph a correction factor is necessary to determine the actual area of the roof. To do this simply convert the rise and run as a fraction to a decimal form eg. Various roof pitches need to be edited used and changed with a calculator to make sure that they are a logistical fit. You need to supply the following information.

This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. 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. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. If your roof is pitched enter the length and width of the flat area covered by the roof.

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. Enter any angle or fraction of angle to find pitch. Length and width of your roof. 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.

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. 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. Measure the rise of your roof. To accurately calculate the area of your roof you must first determine its slope or pitch.

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.
