This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.
Pitched roof slope calculator.
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.
You need to supply the following information.
Various roof pitches need to be edited used and changed with a calculator to make sure that they are a logistical fit.
Total height of building.
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.
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.
After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
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.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
To accurately calculate the area of your roof you must first determine its slope or pitch.
Enter any pitch or fraction of pitch to find angle.
Rise run rise run slope.
Now you re ready to price out the materials.
Enter any angle or fraction of angle to find pitch.
To calculate the weight of snow on a roof use the first two sections of our snow load calculator.
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.
Measure the rise of your 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.
Let s assume it is equal to 6 m.
Length and width of your roof.
To do this simply convert the rise and run as a fraction to a decimal form eg.
First convert the pitch to a slope.
You can enter these values in any units you d like including meters and feet.
If your roof is pitched enter the length and width of the flat area covered by the roof.
This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.
