30 Degree Roof Pitch Chart

A roof pitch of 6 12 26 5 or less is considered easily walkable and no extra precautions are required.

Common roof pitches and equivalent grade degree and radian angles. Pitches between 8 12 and 10 12 33 40 are also considered walkable but it is not advisable and if you have to walk on these roofs extreme caution should be. A roof of pitch 7 12 30 is manageable but caution should be taken. Therefore it s important to understand the roof pitch chart process completely.
