"From start to finish, WE Griffin Roofing did outstanding work. An important aspect as that they are both a roofing company as well as a gutter company, and in our case both sets of expertise were needed. We obtained three bids, and decided to choose WE Griffin because Matt Hoffman gave us such an insightful analysis and estimate of the work needed. We had purchased this house (a 1962 split level) last year, and the gutters were literally falling off their fascia boards and also the fascia boards were coming apart as well. Mr. Hoffman diagnosed that potentially extensive roof repair would also be required, including both the rafter tails as well as the sheeting under the shingles near the edges, and including that work in his estimate along with the gutter and trim replacement. His estimate of the work needed turned out to be very accurate as many of the rafter ends and a whole section of sheeting on the back side were rotted and needed repair/replacement. The crew was similarly excellent; they arrived on site as scheduled and worked tirelessly for nearly 4 days to do all the repair work, replace all the fascia boards, replace some of the missing cladding that had also come off in places, and install a complete set of new gutters. Each day when the crew left they tidied up the site very nicely, and at the end of the project the yard was completely clean. They worked very carefully with a lot of attention to detail. The outcome is that we now have gutters as well as fascia boards and cladding that all look spectacular! We are very pleased with their work."

"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."

"Presidential Exteriors is a great company to do a roof replacement with! We had our roof replaced in early February 2021 and we couldn’t be happier. The whole team was amazing to work with. Nate worked closely with us every step of the way to make sure we were happy and getting the best product and prices possible. He really made us feel like family. Elena was great at communicating every step of the process. The day of installation team was amazing. They dropped off the equipment one day before the project even though it had snowed the night before. The morning they came to do the roof, we still had ice on the roof, but instead of delaying the project, they scraped all of the ice off our roof and still got the whole roof done in one day! Our new roof is great and we couldn’t be happier. We very highly recommend Presidential Exteriors for any roof inspection and roof replacement. We will absolutely be keeping them on our list for any future projects with our house."

"Sunny showed up on time to give me an estimate for repairs, showed the pictures of the work to be done and gave me a very reasonable price, then did the work with materials he had that matched what was already on the roof. I don't this entire process took more than an hour. The added bonus was working with someone who was actually customer service oriented."

"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."

Roofing questions, answered by experts

Tar and gravel roofs last an average of 30 years, which is longer than the average lifespan of many other flat roofs. The gravel on top of the waterproof membrane helps protect the roof from UV damage and physical damage, so if you keep your roof drains clear and carry out annual roof inspections to catch issues early, you could see up to 40 years of useful life from your roof.

The ridge is the horizontal line where two sloping roof sections meet at the top, forming the highest point of the roof. A hip, on the other hand, is the external angle formed where two roof sections meet and slope downward toward the walls, typically at a lower angle than the ridge. The ridge runs horizontally along the peak and the hip runs diagonally from the peak to the roof's edges.

Proposals, invoices, and estimates are most often used as marketing documents and are not legally binding. Contracts are legally binding documents that detail the service offering, project considerations, and signatures from all parties. If you signed a proposal for discussion purposes while requesting a quote and you decide to hire your roofer, make sure the contracting party follows through with a legally binding contract to protect both parties.

No, you can’t use your home’s square footage. You have to calculate your roof’s square footage, and then you may have to convert your square footage measurement to correspond with how the roofing material is measured. For instance, some roofing is sold in “squares,” which equals the total square footage of the roof divided by 100. Shingles are sold in bundles that may not correspond to the number of squares you need. Metal roofing is sold as sheets, so determine the amount of square feet each panel will cover and then divide the total square footage by the coverage area.

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.
