What Our Clients Are Saying

Great job!!! My wife and I were very impressed with our new roof. The workers were very efficient and did an outstanding job. The job was done in one day. We highly recommend the Cassas Brothers for the job. Price was great as well. Thank you!

Ray Garrison

Best roofer around.The ownerr was professional, friendly, and did what he said he was going to do. They replaced my roof after removing two layers of old shingles and replacing 5 pieces of plywood all in one day. Both neighbors asked who did my roof because they were clean, fast, and the roof looks the best on the block. I gave both my neighbors Cassas Bros cards.

Dominick D.

I recently replaced my roof which consisted of separate roofs and were very pleased with the quality of workmanship and price. The cleanup afterwards was great. I would strongly recommend this company to anyone needing a new roof replacement. Thank you.
