"All under one roof did a fantastic job removing two layers of shingles and installing new roof. The whole team was hard working and completed the job in one day. When they were done my yard was cleaned of all debris. I highly recommend All Under one roof."

"Three weeks ago I decided to replace my 30 year old. I Googled roofing contractors and happened upon Scottâ s Roofing . I started reading their reviews and they were all five star and very complimentary. I called and talked to Sean Nadeau, one of the principals in the company.and he promptly sent a detailed proposal including the workmanâ s Compensation & General Liability insurance certificates. I then called and spoke to Darby Sullivan, office manager and she was very patient while we finalized the contract. Scott â s Roofing arrived on time, stripped and replaced the roof in the most professional way. Kevin, an on-site supervisor was present. Sean also arrived mid morning to check on the progress. The crew worked very hard and I could not have been more pleased with the outcome of the roof installation. I would like to thank Sean, Darby, Kevin & the crew for all of their hard work and attention to detail. This review, like all of the other reviews, merits the five star rating. Use â Scottâ s Roofing â and you will not be disappointed. Henry J. Pagliarulo"

"I had shingles blow off the roof this winter. They were very good about keeping track of the weather and repaired the roof as soon as the snow was gone. They came over fixed the roof, cleaned up and were gone. Very good service."

Roofing questions, answered by experts

Yes, algae-resistant shingles will prevent algae and moss growth, providing double protection for your roof and roof flashing. The copper-infused granules on algae-resistant shingles release copper ions that inhibit plant growth in general, so moss will have a harder time growing on your roof, too. Keep in mind that copper ions flowing off your roof during rainfall can also inhibit plant growth below, so your gardens and grass may be affected.

Roof work is dangerous and exacting, and a misstep could lead to even more costly repairs, so we do not recommend DIYing. If you are dead set on giving it a go, practice safety measures. Wear a harness, only work during mild weather, and have a partner to help. Potentially DIY-friendly jobs include patching up small leaks, sealing areas around the chimney, and replacing a few shingles.

Unlike wood decks, Trex decking doesn’t warp. That’s one of the key benefits of installing this decking material. Over time, common issues with these decks include hard water stains, mold or mildew growth, and stains from food spills. Thankfully, with proper cleaning, you can get rid of most stains and mold.

Ridge vents can last as long as your roof does. As long as your ridge vents were installed correctly by a qualified professional, they will need very little upkeep. Inspecting your ridge vents annually to ensure they aren’t cracked, clogged, or leaking will help prolong their lifespan. 

Roof blistering and hail damage are different in their physical appearance. Blistering, often caused by inadequate ventilation, low-quality material, and improper installation, looks like large, irregular bubbles popping out of your roof. Meanwhile, hail damage is usually circular or oval dents entering your roof and often follows the same path as the hail storm.
