Apex Juncture
On this roof juncture (Figure 12) metal flashing should cover the top 8\'94 of the roof and the top 4\'94 of the wall. It should be installed before the final course of Certi-label™ shakes or shingles is applied to the wall. The recommended sequence of application is to apply Certi-label™ shakes or shingles first to the wall then to the roof. The overhanging roof material is then trimmed flush with the wall. Finally, specially prepared ridge units are applied over the wall-roof juncture so that in each matching pair the roof piece overlaps the wall piece each time.
Swept or Bell Eave
When Certi-label™ shakes or shingles are to be applied to a swept or bell eave where the curvature is excessive, it may be necessary to soak them for a period (usually overnight) or steam them prior to installation. A double starter course is employed in the usual manner. Exposure is determined by the slope of the roof and the type of Certi-label™ shake or shingle selected. At lower pitches waterproof eave protection should be used.
