Minum Pitch On A Steel Roof

Corrugated metal roofing has the same minimum pitch.

Minum pitch on a steel roof.

The standard of lower pitch actually ranges between 1 12 to 5 12. To get the minimum pitch for a metal roof the vertical rise per foot is divided by the horizontal slope. Panels joined with an applied lap sealant can go as low as 12. Run in degrees and as percentage the minimum roof slope allowed by code for any type of roof is in 12 applicable only to coal tar pitch roof systems.

The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12. That means there is at least 3 of vertical rise to the roof slope for every 12 it goes back horizontally. Most residential metal roofs require at least a 3 12 roof pitch and have no maximum roof pitch. For low slope metal roofs under 12 that are nearly flat modified bitumen roofing thermoset and.

Roof slope equivalents as rise. The following table provides the minimum required. After that the miimum pitch for metal panels depending on the methods used to join the panels. That is a 14 degree angle.

Anything above that will require you to put out higher cost because they are already considered as higher pitch.
