Feb 10, 2021 · Calculate the roof pitch as the proportion of rise and run:pitch = rise / run = 1.5 / 6 = 25%. Recalculate this value into an angle:angle = arctan(pitch) = arctan(0.25) = 14° Finally, you can find the roof pitch in the form of x:12. x = pitch * 12 = 0.25 * 12 = 3. The pitch of your roof is 3:12. It can also be written down as 25% or 14°.
