"Quality firm that does great work. They put a new roof on 12+ years ago and recently came out to give us a "tune-up". Cement roof tiles. Looks like new. No issues and very responsive. Good folks."

"I bought my home last year and with it came a roof that had seen better days. Jonathan from Small Dog Roofing did a great job walking me through the process for a full replacement and I could not be happier with the quality of service and product. Definitely recommend for your roofing needs!"

"Kevin and his crew showed up early and got right to work. Finish product is looking great. There was a small issue with a few of the baffles in the attic not being secured correctly and Kevin took care of it quickly. Would definitely recommend JP Carroll."

"Having reached out to several roofing contractors I found the initial team (Steve quoted the job and Mark who is the owner) to be knowledgeable, extremely professional and competitive with the price. After signing the agreement I was assigned a representative (I was in contact with Paul) and he kept me updated on the timing of shingle delivery, dumpster and when the crew would be onsite to work. The work was completed within the timeframe they quoted and was done well. The roof looks great and they made sure the area around the house was left spotless without bits of shingles or nails. I would definitely hire them again and feel comfortable recommending them as a quality roofing company."
