Just a couple of questions regarding sidewall shingles with white cedar
extras. At HD, they sell them by the bundle.
1. What is the typical exposure you guys use for the shingles ? i.e. 5.5
2. At the typical exposure, how many bundles per square ?
I found this formula on the web. I am curious if this is correct.
Add the butt ends of a bundle together (20+20 = 40
Divide that by '8'. (40/8=5)
Multiply the result x the exposure you want to use (5 x 5.5" exposure '.5
sq ft) of bundle coverage
Approx 4 bundles per square.
