If the pitch of your roof is 6 inches per 2 inches the angle would be 26 5 degrees. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12.

Since most building codes require a pitch of at least one quarter inch per 12 inches you should anticipate that the angle of your roof will be at least 4 degrees. The minimum pitch for roll roofing is 2 12 or 2 inches rise to 12 inches run. Be sure the larger edge is laid so that the small edge of the next panel will overlap it. Examples of extreme slopes range from 1 4 12 almost flat to 12 12 sloping down at a perfect 45 degree angle.

Standing seam metal roofs with mechanical lock systems to ward off leaks can be successfully and attractively installed on roofs with at least a slope of 1 in 12. A roof that slopes 12 inches for every 12 inches would have a 45 degree angle. Slate metal tiles shingle and others. This is the basis for calculating the angle which is approximately a 1 19 degree slope.

It must be clearly equals to thirty five degrees. Align the first metal roofing panel so that it overlaps the edging by 1 2 to 3 4 of an inch and is square to the roof line.
