The flashing detail at left applies to both reduced pitch (shown) and increased pitch. Reduced pitch — change flashing can be avoided in favor of a cleaner detail by bending asphalt shingles or by soaking or steaming and bending wood shingles. The pitch change can also be made gradual by adding a strip of sheathing at the bend in the roof (see below) so that stiffer roofing materials such as wood shingles and shakes, tiles and slates can make the transition without flashing.
