Pitched Roof Slope Calculator

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

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. To do this simply convert the rise and run as a fraction to a decimal form eg. This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. First convert the pitch to a slope.

You need to supply the following information. Enter any angle or fraction of angle to find pitch. 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. Measure the rise of your roof.

Total height of building. After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually. 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. Enter any pitch or fraction of pitch to find angle.

If your roof is pitched enter the length and width of the flat area covered by the roof. To calculate the weight of snow on a roof use the first two sections of our snow load calculator. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Length and width of your roof.

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. This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. Now you re ready to price out the materials. 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 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. Let s assume it is equal to 6 m. 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.

Various roof pitches need to be edited used and changed with a calculator to make sure that they are a logistical fit. Rise run rise run slope.
