Get matched with top flat, foam or single ply roofing repairers in Potomac, MD

"I would not hesitate to recommend - responsive, great communication, reasonable pricing. We had a disastrous roof flooding experience from a flat roofed dormer and needed it fixed quickly. As Roberto worked on the dormers he found significant water damage below the shingles, documenting it with photos for us. Although it cost more than the original estimate to replace the flat plywood sheaths and wood fascia, it was still reasonable and the work done was thorough and looks great."

"Certified roofing did very well. They were the first to respond to my Angi query. Tim was smart, quick, and had an excellent work ethic. We had a slight miscommunication on what the job entailed, which is being cleared up as we speak. I would definitely hire them again."

"Great job. The sales person was very good they set dates for the job to start and being completed. They showed up on time and completed the job on time. Would recommend them to anyone needing a roof replaced or repaired."

"They did an excellent job; they were very responsive to our problem of the vends leaking. Their crew we very professional, courteous and competent. Highly recommend them for any roofing issues."

"I thought Presidential did a good job replacing my roof. I thought the pricing was fair and the job was done from first contact with the company to finish in ~1 month. I would use them for home repair services again."

"After years of unsuccessfully addressing water damage around windows in an upstairs room by focusing on the window frames and the brickwork around the windows, I asked W. E. Griffin Roofing (whom I had used previously for relatively minor roofing repairs) to evaluate whether the roof was a factor. Matt Hoffman determined that significant work had to be done including substantially rebuilding two dormers, removing and replacing valleys and flashing, and replacing the roof on the dormers. As in the case of previous and subsequent jobs, Griffin's work crew was very professional and conscientious at all times. They cleared all rubble and tools from the site every day, and the job was started and completed on schedule. In the 4 years since this work was done and the interior water damage repaired, there has been no further sign of water damage in that room. I completely trust the advice I have received from Matt Hoffman over the past 7 years since I first used W. E. Griffin. In addition to the work described above as well as routine preventive maintenance, I have also engaged the company to repair gutters, replace incorrectly installed snow guards, replace failed chimney flashing, fabricate and install catch boxes to prevent leaf blockage of downspouts, as well as routine preventive maintenance. I would recommend them without reservation."

"They charged me more than I was expecting. My attic was taller and they had to put a bigger tube in. One of the areas in my house is somewhat dark during the daytime. What they do is cut a hole in the attic like similar to an attic fan and put a hole and put kind of a globe looking thing which basically allows the natural sunlight to come in. They install an aluminum tube and it can be bent to where you need the light and then put a cover on it. I have mine in the middle of the house where my stairs are at because it was kind of dark there with the rooms around them. I have had 1 or 2 minor issues and they came over to fix it for me other than that it has been alright. I had researched the parts and they was like $200 to $300. I thought it would take a couple hours and maybe $100.00 or $150.00 an hour but it cost me more than $1000.00."

"H Forrest repaired broken mortar on my nearly 75-year-old brick home and rebuilt a chimney that had allowed water to enter the house. Henry’s team also replaced a rubber roof covering our front porch. They do excellent work and are very good about explaining what they recommend and why. We have another project planned for this fall or next spring and I plan to use them again."

"We've had these guys do a variety of exterior projects for us (fixing roofing leaks, installing new gutters, etc.) and they've been one of the best companies we've ever worked with. Reliable, honest, and high quality work at a competitive price. We've referred them to several friends, most recently our neighbors, and they've all been pleased as well. Our neighbor reached out expressly to say thank you for the suggestion they were so pleased with their great service. I highly recommend Alex and his crew"

"Very happy with the company very nice people, wonderful service, amazingly fast would most definitely recommend to anyone needing roof repair/ replacement 10 stars for me."
