"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."

"Griffin Roofing installed a new copper roof beneath our roof deck, reinstalled our roof deck, installed a new copper roof above the bay window walkout, installed new sewage vent pipe flashing, replaced missing/broken slates, install new gutters, and sealed the ridge with asphalt sealant. The crew worked diligently despite the hot weather. Matt was accessible, friendly, and understood our needs. He answered the many questions that I had. The budgeting number they gave us at the outset ended up being the price. They were able to complete the job before my daughters birthday party as they stated they would. I would use them again."

"We bought our house in 2012 in Montgomery County, MD. The roof was past its design life when we bought the place, and although there were no signs of leaks, we decided to put a new roof on the house in 2016 - better to get it done before problems arise than after. Central was great. I forgot to move my car out of the driveway the morning they were scheduled to start work but they managed to make things work anyway. My handyman happened to stop by while they were working and told me it looked like they knew what they were doing, which was comforting. The real proof, though, is my roof has been on the house for 4 years, including the wettest year on record here in the DC area, with no signs of leaks anywhere in the house. This may not seem impressive - roofs aren't supposed to leak. However, both my sister and parents have had new roofs put on their houses in the intervening years - they live several States away so could not use Central Exteriors. Both had leak issues after having the new roofs put on and had to have the roofer come back out to fix things - in my sister's case it took several return visits and some major work to make things right. Central Exteriors were price competitive with other roofing companies I consulted with, and gave me a 50 year warranty on the shingles and workmanship, which nobody else offered. I would not hesitate to hire them again. Very pleased."

"We were convinced to have our roof done after the roofing expert inspected our roof and sat us down for his presentation. We appreciated the time spent to explain the project management plan from the delivery of materials to the post-installation inspection. Everyone we met was very professional and the clean up crew did a great job."

"Sunny Lee and his firm are excellent. He is easy to work with, and his price is competitive and reasonable. He came promptly to look at our leaking roof, and covered it with tarp at our request. The roof was replaced in a day. We also appreciated his honesty that the gutter didn't need to be replaced yet. We are very pleased with his work, and will not hesitate to use his company again in the future. We will also recommend him to friends and neighbors."

"I used Unicorp to replace my roof and siding and the entire experience was hassle-free. Brian came to my house on a weekend to assess my needs & provide a quote. I was assigned a team at Unicorp. Every single member of that team (Megan, JR, and Brian) were always available and courteous. In addition to courteous interactions, the work on my house was flawless. I am so happy with the new roof, shutters, & siding. Everyone in my neighborhood could tell during installation that this company was professional & once the work was completed many of my neighbors said I have the nicest house in the neighborhood. After installation another company damaged my newly installed siding. Unicorp responded immediately and the repairs were made - again hassle-fee. I wish I had known about Unicorp years ago when I replaced my windows. This is THE COMPANY to use for roofing, siding, windows. QUALITY PRODUCTS PROPERLY INSTALLED BY THE MOST PROFESSIONAL STAFF."
