I have never been keen on such a shallow pitch especially with velux in.

10 degree roof pitch options. Some sources consider low slope to include 3 12 pitch roofs. 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. What degree angle is a 12 12 pitch roof. This means for every 12 horizontal units the roof must rise a minimum of one eighth vertical unit.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.
