Get matched with top roof sealant application pros in Rockville, MD

"Excellent, finished and left no trace of being there within one day. Also despite being the largest roofing company of the quotes I received, they had the cheapest ones. Also gave you three different options with a checkmark table displaying the differences of what you are getting with each option. Thinking about calling them for my gutters. Professionals."

"We had a roof leak and Amazing Skylights made quick work of it. They were very helpful and responsive and saved us from further water damage. It's been six months and no recurring issues. We had a great experience with them."

"We received a drive-by visit in early September from Presidential Exteriors canvassing the neighborhood and while we knew we were living on borrowed time, with our roof last replaced before 1991, we don't do business with companies we don't know and trust. In this case I said no thank you, and the canvasser made a last comment that struck a chord, to look them up online. After checking their references, even though a fairly new company, they had very positive feedback in Angie's List. I then called and made an appointment and my wife and I were impressed with the salesperson, Ben (we've never had someone climb around the unfinished attic in completing their assessment) for his knowledge, genuineness, detail, and approach, and we signed a contract to renovate our roofing with architectural tiles and to install wider gutters (all in preparation for global warming). Over two days, the crew of two performed an amazing job at removing multiple layers of very old shingles (resulting in less full shingles being removed, and mostly partially torn pieces) and the care and cleanup left the full area around the house and bushes almost clean. Understandably, with any re-roofing I cannot imagine you wouldn't have some small amount of cleanup and a few full handfuls of nails and staples over the following months. In our case, in the subsequent week we have found over 60 nails so far using our own magnetic broom (purchased at Home Depot). The third day found the crew finishing the roofing and the other contractors arriving to remove and install the new gutters. So far, the new roof and rain gutters look great and we're cautiously awaiting the approaching storm season."

"When I called the company, they came to my house within 30 minutes to do an estimate because I told them I had open holes in my roof. Ben came and made me feel confident in his abilities to assess the roof and recommend the best roof for me. The workmen came and put the roof on quickly and meticulously cleaned up after themselves. A snow storm was predicted in 2 days, and another man from the company came before the snow to check and be sure everything was taken care of and solid. They also installed a ridge vent. I highly recommend this comapny. My roof is beautiful and definitely adds value to my home."

"I hired Moses Williamson to clear my gutters and downspouts. His crew noticed cement debris laying on the roof. Moses inspected the damage and it turned out I had a damaged chimney crown that required replacement. In addition, the brick chimney needed tuckpointing in several places to refill the mortar joints. His crew replaced the cement crown, tuckpointed the chimney, and applied a clear sealer over the entire surface. Based on Mosesâ recommendation I agreed to have the brick facade spot tuckpointed and sealed. In truth I had previously noticed small spots of missing mortar on the brick front but had simply put off addressing. I found Moses to be knowledgeable, professional and friendly. He showed me photos of the crown damage, and patiently answered my many questions. And yes, the gutters and downspouts were cleared. I highly recommend Moses Williamson for gutter and roofing maintenance and repair services."

"I would recommend Power General Contractors for all your roofing repairs."
