"In a word, our experience was "FANTASTIC." First, the PEOPLE: Tom (the owner) listened carefully to my concerns about our old roof; gave it a close inspection; and recommended a perfect solution ("Weathered Wood shingles," "Winterberry shutters"). The front office staff were friendly, easy to work with, and answered all of my questions patiently and promptly. The supervisor, foreman, and crew who did the work were exceptional -- rarely have I have seen a team as focused, steady, and conscientious as they were. They were well trained and high-performing -- bar none -- and they did a THOROUGH cleanup job afterward. Next, the PRODUCT: We are very impressed with the Landmark Pro architectural shingles -- they are solid, attractive, and match our landscape beautifully. Also, the crew was trained by CertainTeed, and it showed: The shingle lines were straight and true, with no defects at all. And the ridge vents are GREAT! We've already noticed how much cooler our attic is. Very nice! And they installed four new Velux skylights -- again, the product is beautiful and the installation was tight and true (no leaks this time!). Third, the PRICE: It was fair and reasonable for the quality of the product and the work done (covering four roofs plus one shed). We have no complaints at all. A fair price for an excellent job. Finally, TIMELINESS: Certified Inc. was able to do the job within two weeks after I signed the contract. Unbelievable -- but they did it! I strongly recommend Certified Inc. to anybody who needs a new roof -- and I'm actively telling my friends and co-workers the same thing."

"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."

"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."

"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."

"The techs, Mikey and Chris, were flawless. Very professional, knowledgeable and pleasant to work with. The fixed the immediate problem of a missing cap shingle and did detailed maintenance on the rest of the roof. Their report was very helpful."

"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."

"The young man that came to see my missing shingles on my roof, was professional, informed, and polite. The only issue was that the company does NOT conduct repair as I needed. The company only replaces the entire roof. I am glad he came and advised about replacing the roof if we decide to do that and decide that we can afford it. Right now I need to repair the missing shingles. and he/ his company can not help me."

"Hello Just wanted to let you know that I was very very pleased with the service provided me by Mr. Jose Mr Mr. Jose Farfan. He was very professional and polite. He did an amazing job repairing my aluminum siding. I requested server of his business cards to give to my friends and neighbors. He has a keeper. Debbie Foote"
