Profile in the context of metal roofing means the shape that the sheet of metal is bent into to form the panels. Corrugated roofing is a great material on traditional pitched roofs but it has severe limitations when the pitch gets below 5 degrees.

Minimum required slope x in 12 minimum required slope degrees asphalt shingles. The corrugated metal roof minimum slope is 5 degrees. Roofing material or system. Pitch angle incline slope they all can be used to refer to the steepness of a roof.

It is the recommended slope as there is no guarantee if you opt for flatter pitch than this. Most residential metal roofs require at least a 3 12 roof pitch and have no maximum roof pitch. The minimum pitch for a lapped non sealed metal roof is 3 12. Lapped metal roofs with sealant between the laps can go as low as 12 which equals around 2 5 degrees.

That means there is at least 3 of vertical rise to the roof slope for every 12 it goes back horizontally. The pitch is measured in inches of vertical rise per foot of horizontal run and the 5v crimp profile shown above requires a minimum slope of three in. That is a 14 degree angle. The minimum slope for standing seam of roof systems shall be one quarter unit vertical in 12 units horizontal 2 percent slope.

Minimum pitch for corrugated metal roof corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch. 18 43 asphalt shingles with special underlayment requirements 2 in 12. In the roofing trade the go to term is pitch and it is expressed in terms of 12 inches so the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally. 9 46 built up roof asphalt.

That is why all roofing manufacturers recommend the 5 degree pitch as the minimum slope and they will not provide any guarantees if it is installed flatter than this.
