About this product
Roof Replacement for Portland 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).

What homeowners say about our Roof Replacement
★★★★★
"Frank and dereck from Coastal Windows&Exteriors were great, they were professionals, knowledgeable, they took the time to listen and answer all my questions. I just signed the contract today and I will leave another review as soon as the project is finished . it is very hard to make choice and decision when it comes to replacing the roof, a lot of money to commit to, but they made it easy and understandable , and it look good start so far. Thank you guys!!!"
★★★★★
"Excellent roof replacement by Coastal Windows & Exteriors in Kittery. Manager Steve Schofield provided great communication and went out of his way to help . The crew worked from dawn to dusk to ensure our home was watertight before an incoming northeaster. They replaced rotted trim and soffit, installed new GAF shingles beautifully, and left the property spotless. Highly recommend!"
★★★★★
"Cody and Conner were extremely helpful and knowledgeable when quoting our project (roof, siding, and window replacement). They arrived on time and prepared which made this go even smoother. They walked us through all aspects of material used and any problem areas they noticed. They then worked with us on a solution based on what we were looking to spend. Happy to have chosen Coastal to do this project."

Cost
How much does Roof Replacement cost in Portland, ME?
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.
