"I chose Certified for my new roof because my neighbor used them and had a good experience. I made the right choice. They explained all the components of my new roof and the costs very clearly. The job was completed exactly as explained and within the time frame. The roofing team - supervisors and workers - were courteous, professional, and very careful. They moved all of my flower pots, etc. to be safe during the process removing the old roof, and cleaned up meticulously afterwards, including retrieving any old shingles that may have dropped into my neighbors yard. Although they were a little higher priced than one other estimate I got, I chose them because they were professional and thorough and very easy to work with. I'm very happy with the result. Thank you."

"We hired Cox to repair/replace the both sides of the church's pitch roof at Our Lady of Hope Church in Dundalk. They took off the old roof, added plywood, new cloth and shingles. We are talking about a roof that is 1000's of square feet! The job was done within the allotted time. The clean-up was superb! The price was 17% below the closest bid price. A most excellent result from a fantastic company."

"Great customer service The project was done on time My flat roof repair turned out great and very reasonable"

"It is a work in progress; still need to see how well the repairs hold up under heavy rainfall and wind. Then I will be able to finalize my assessment of the work done."

"I am very pleased with the quality of work done on my roof replacement here in Bowie and especially the quality of the products used; Owens Corning Duration Amber architecture shingles and the synthetic underlayment. I'm looking forward to decades of good looking high performance upgrades from Owens Corning."

"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 well, Mike was very clear about the root causes of the spots and our choices ranging from minor repairs to the roof to re-shingling."

"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."

"If Erick Castro, and the ExteriorMax team, tells you he can partner with you and your homeownerâ s insurance to replace your roof, believe him! Iâ d had a roof replacement on my long-term home project list for a long time. Itâ s just one of those projects that is hard to justify if you canâ t see it and itâ s not leaking! A recent storm resulted in a few shingles missing and Erick and team proactively reached out to let me know how they could help, based on the age and availability of similar materials. What seemed too good to be true resulted in one of the best home improvement projects Iâ ve experienced. In addition to the way Erick activated the process of assessing our needs, he helped run point as our advocate throughout claim process. The extended ExteriorMax team exceeded my expectations in communication, organization, cost estimates, timelines, and quality of work. They truly function as a cohesive team who support each other and the customer. If only more companies and teams operated at this level of execution on delivery and service to their customers."
