Corrugated metal roofing has the same minimum pitch.

Minimum pitch for corrugated metal roof. For low slope metal roofs under 12 that are nearly flat modified bitumen roofing thermoset and. Panels joined with an applied lap sealant can go as low as 12. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12.

The most common disregard for engineering logic is the rule of minimum pitch for corrugated iron roofing. The overlaps ends and sides depends upon the sloop of the roof. In most occasions a pitch of three in twelve is preferred but this should also take into consideration the manufacturer s recommendations as well the unique condition of the. The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12.

Corrugated sheet roofing.
