How To Measure The Pitch Of A Roof In Degrees

Hold the 0 mark of the tape measure against the roof.

How to measure the pitch of a roof in degrees.

Extend it upward so it is perpendicular to the level. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. 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. 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.

So use the 12 inch level as a constant run and 18 inch ruler as a variable rise. First find the slope by finding the tangent of the degrees eg. Recalculate this value into an angle. Pitch rise run 1 5 6 25.

Move the tape measure along the the roof until it hits the level at exactly the 12 inch mark. The pitch of your roof is 3 12. Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. Unfortunately translating the pitch of a roof into a degree format is actually much more difficult than it may initially appear.

How to convert angle in degrees to roof pitch. You will need to possess a knowledge of trigonometry in order to obtain accurate results. It can also be written down as 25 or 14. Measure the vertical distance from roof to level.

This is why it is normally wise to use an online pitch converter. Roof pitch degree table. Then multiply the slope by 12 to get the rise. 8 12 pitch 33 75 degrees.

Pitch tan angle use this when you express the angle of the roof pitch in degrees what is the standard pitch of a roof. Calculate the roof pitch as the proportion of rise and run. X pitch 12 0 25 12 3. To see roof pitch visual examples.

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. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
