How To Measure The Pitch Of A Roof In Degrees

It can also be written down as 25 or 14.

How to measure the pitch of a roof in degrees.

This is why it is normally wise to use an online pitch converter. Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Move the tape measure along the the roof until it hits the level at exactly the 12 inch mark.

So use the 12 inch level as a constant run and 18 inch ruler as a variable rise. Hold the 0 mark of the tape measure against the roof. You will need to possess a knowledge of trigonometry in order to obtain accurate results. The 12 inch run is considered standard in roof pitch or angle terminologies.

Angle arctan pitch arctan 0 25 14 finally you can find the roof pitch in the form of x 12. Measure the vertical distance from roof to level. This drawing demonstrates how many degrees rise for each pitch of a typical roof. Unfortunately translating the pitch of a roof into a degree format is actually much more difficult than it may initially appear.

The pitch of your roof is 3 12. First find the slope by finding the tangent of the degrees eg. Calculate the roof pitch as the proportion of rise and run. Roof pitch degree table.

Then multiply the slope by 12 to get the rise. Extend it upward so it is perpendicular to the level. 8 12 pitch 33 75 degrees. If you know the angle of the roof in degrees you can find the roof pitch by converting the angle in degrees to a slope then finding the rise by multiplying the slope by 12.

Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. To see roof pitch visual examples. X pitch 12 0 25 12 3. Recalculate this value into an angle.

Pitch rise run 1 5 6 25. Pitch tan angle use this when you express the angle of the roof pitch in degrees what is the standard pitch of a roof. Locate its tangent or tan and follow the left row for you to read its corresponding degree.
