What Shingles do we use? Why?

We only install CertainTeed Shingles. Why would we limit ourselves to one brand? They are the only brand that keeps up with our quality. They are by far the best shingle you can put on your home. Their warranties are unmatched, and the quality is impeccable. The size alone makes them the heaviest shingle on the market. We spare no expense in providing the best of the best.
