Shingles

Shingles are usually redwood, cedar or cypress. They are smooth sawn and of uniform size and shape. They are applied from the bottom up and overlap each other a bit as the next highest row is applied. Some people prefer to have their shingles overlap in various amounts to give a different look or texture. Shingles can be applied in a single course, where all shingles are exposed to the elements or a double course in which only the top layer of shingles is exposed. Shingles are prone to cupping, a rolling of the shingle toward the center, and checking, which is a cracking or splitting.
