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