As of january 1 2010 the california energy commission s updated title 24 building energy efficiency standards for residential and non residential roofing are now in force otherwise know as cool roof. It is the recommended slope as there is no guarantee if you opt for flatter pitch than this. A common range is given from 1 12 to 4 12 whereas conventional dimensions vary from 4 12 to 9 12 but the steep roofing technique follows slope above 9 12 with additional fasteners. On roofs with a slope of 4 12 or greater use a single layer of 15 lb.

Standard test method for granule adhesion to mineral surfaced roofing by abrasion. You need to consider the slope requirements of each panel to determine this minimum slope. Asphalt shingles are appropriate on roofs with conventional pitches between 4 12 and 9 12. Low slope or flat roofs should not be roofed with asphalt shingles because it is much easier for water to infiltrate the roofing material on a roof with a shallow pitch.

The corrugated metal roof minimum slope is 5 degrees. The minimum slope of a roof depends on the roof s profile. D4977 d4977m 20. Standard practice for dark oven heat exposure of roofing and waterproofing materials.

Corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch.
