"I highly recommend Cox roofing to anybody who is considering having a new roof installed. They very affordable, prompt, and professional, They also communicated well from start to finish. I received before and after pictures of the project."

"Good price, great people. Goes the extra mile to do a quality job. Billy went to four Home Depot stores to find the exact shingle to match our church roof. Great fun working with craftsmen with old world values. Will recommend to members and friends. Albert R. Gwynnn Oak, Maryland."

"The guys were very professional and polite, they did a great job. This is the second time we have used them and we would definitely hire them again. They replaced the missing shingles, checked the entire roof, flashings, pipe sealants, and ridge vents. They sealed everything that needed touched up. They also cleaned and tightened up the gutters and downspouts. Once they were done they made sure everything was cleaned up behind them."

"Their consultant was on time and very knowledgeable. I ultimately decided to move forward with a new Roof and replacement windows. My Roof was done roughly 2 weeks later and my windows were just completed. I am very pleased and look forward to the energy savings this winter. The architectural shingles really look good and have gotten me a lot of compliments from my neighbors."

"The roofing crew was phenomenal. They did something I have never seen before—they put tarps on all the bushes around the house. In addition to the shingles, they also had to replace all the wood under it. They did beautiful work! They treated our property with the care they would have used on their own homes."

"Bought my house in 2017 and told it had a new roof. Came to find in 2025 that it had been totally botched. Shingles were coming up, there were large holes where knots in the frame had been knocked out by nails, and I had severe water damage on one of my trusses. Roof Pups came out, assessed the damage, worked with me on the price, and in less than a week I had a crew on site that fixed everything in a single day. They were here for over 12 hours making sure the job got done and they did a great job. I couldn't be happier with my experience."

"Very pleased with the entire roof install project. I would recommend them to anyone looking for roofing repairs. Dylan and Allan's crew handled everything seamlessly from start to finish."

"They were timely and professional for our roof repair."

"We had a wonderful experience all around with Power. All the crews came on their scheduled dates and times. From start to finish everyone was very professional, polite, diligent, knowledgeable, and neat and precise in their work. All the teamwork on this large (to us!) project was simply amazing. I have no idea what this type of work entails but I do know a "well-oiled machine" when I see one. Our roof, trim, gutters, attic, and siding look stunning and my husband and I are extremely pleased with the outcome.
