Shake & Shingle Roof Application Instructions
Watkins is your valuable resource for installing Western Red Cedar Shake and Shingles
Tapersawn Cedar Shakes
The shingle/split shake hybrid.
A Certi-Sawn red cedar shake is sawn both faces but is thicker than a shingle. The added thickness enables it to be applied as a shake (2 ply with paper/felt interlay) resulting in lower application costs. Many architects like the more defined shadowline of the heavier butt and yet still get the cleaner look of a sawn product.
- Sawn on both sides
- Smooth Uniform look with added durability

Exposures: The hip & ridge exposure should be equal to or less than the exposure in the field of the roof, and should not exceed the maximum exposure for the specified length and grade.

However, in many areas a tapersawn hip and ridge unit is used on both shingle and shake applications. Hip and ridge product type selection should be performed in accordance with the aesthetic look desired.
