About this product

Roof Replacement for Dover homes

We install GAF architectural shingle roof systems — deck-to-cap — as a GAF Master Elite contractor, a designation held by fewer than 2% of U.S. roofers. That certification unlocks the Golden Pledge® warranty, which covers workmanship for 25 years. Every roof includes proper attic ventilation, ice-and-water shield at the eaves and valleys, and a full-tear-off (never a lay-over).

  • GAF Timberline HDZ® architectural shingles
  • Ice-and-water shield at eaves and valleys
  • Full tear-off — never a lay-over
  • Proper intake + ridge ventilation

What homeowners say about our Roof Replacement

★★★★★

"We contacted Coastal Windows & Exteriors after experiencing every homeowner's nightmare. It had been raining consistently in the past two weeks and finally, last Thursday, our living room ceiling collapsed under the weight of saturated insulation. There must be a leak, and we were scared at how long water was collecting and the possible damage. As it is a family home, I cannot fully express the anxiety we all were feeling.A trusted friend and had told me about her wonderful experience with Coastal working on her home, so I immediately asked her for information and called them that day.Ewan came to our home the very next day, also a rainy one, and performed an inspection. He was initially outside, taking pictures and notes before coming into the home to see the exposed ceiling and attic. When we finally sat down he talked to us about vulnerabilities he identified in the roof, siding, and windows. Owning a very old home with asbestos siding, we knew this was going to be big project for us.And we were a bit overwhelmed with the terminology and how massive a project it would be to repair and protect our house after hearing the news. We knew we had wanted to redo the siding to protect our cherished victorian home, but we had just installed a new roof from another company 7 years ago, and thought we had some time to save for the next siding project.But Ewan was a calm presence as he would stop and explain terms and essentially gave us a primer on roofs and siding we never thought we needed! He was a true educator, explaining the components and materials that Coastal uses in their process. And having our questions answered as we talked was tremendous in helping us understand what we needed to do next in addressing this roof/siding failure.In the next couple of days, fearing additional rain, Ewan quickly responded to our concerns and got us a temporary tarp/covering to protect the home from continued rainfall. He really helped us feel like we were in the right hands while dealing with this emergency.Coastal has already ordered our materials for work on our roof this week, and Ewan was just back at our home to finalize the additional siding and replacement windows. Again, learning more about how siding worked and feeling better about what we were buying. Ewan understood that this was a huge financial investment for us and talked us through the whole way. The level of customer care so far has been amazing and we feel so much more at ease to be working with Coastal."

"It was time to be proactive on an aging roof and skylights. Coastal offers a GAF Golden Pledge Presidents club warranty to ensure that we are protecting our home. Communication from the beginning to the punctuality and hard work from the crew was top notch. The architectural shingles with black trim, seamless black gutters and leaf guards look incredible. Solar vented skylights from Velux, remote operated with power blinds allowed us to toss the operating pole for the old crank version in the dumpster. Everything was tarped, cleaned and a Magnet nail sweep at completion. Follow up for customer satisfaction solidified the communication from start to finish. Thank you Coastal!"

"My husband and I found massive rot damage under our vinyl siding while in the process of building a new deck. After several quotes and chats with contractors we spoke with Dave Barresi who came out and evaluated everything from top to bottom offering different solutions at different price points and never pressuring us. We ended up replacing all of our windows with Harvey Tributes, all siding with a beautiful fiber cement James Hardie siding, and new gutters. They made it easy, painless, and affordable. I can't recommend them enough. My husband works in the construction field and recognizes high quality work. Coastal was the only company we wanted to work with and Dave was the only guy we trusted. Our friends all want referrals!"

FAQ

Roof ReplacementDover questions

Most asphalt roofs last 15–30 years; GAF Timberline HDZ® architectural shingles can last 30–50 years with proper install and ventilation. Watch for curling shingles, granule loss, and daylight visible from the attic.

Cost

How much does Roof Replacement cost in Dover, NH?

Roof pricing comes down to roof size in squares, pitch, the number of layers being torn off, and complexity — valleys, dormers, chimneys, and skylights all add flashing work. Rotted decking found during tear-off, and any ventilation the roof is missing, factor in as well. We inspect and measure the roof before quoting, and the estimate spells out what's included so there are no surprises mid-project.
