Pitched Roof Slope Calculator

Total height of building.

Pitched roof slope calculator.

Now you re ready to price out the materials. First convert the pitch to a slope. 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. After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually.

Enter any pitch or fraction of pitch to find angle. To accurately calculate the area of your roof you must first determine its slope or pitch. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. You can enter these values in any units you d like including meters and feet.

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. 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. 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.

This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. Enter any angle or fraction of angle to find pitch. If your roof is pitched enter the length and width of the flat area covered by the roof. 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 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. 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. 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.

To do this simply convert the rise and run as a fraction to a decimal form eg. 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. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. To calculate the weight of snow on a roof use the first two sections of our snow load calculator.

This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. You need to supply the following information.
