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