"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."

"Len Gibely did a great job helping us when our house was damaged by a tree falling and hitting our porch. Very shortly after the storm they came and put temporary patches on our roof. As soon as it was practical they repaired our main roof and gutters and removed the damaged porch roof. Then in the time frame they told us they came back and did a great job reconstructing and improving our porch roof. I would highly recommend them to work with, they are professional, responsive and they communicate clearly and accurately throughout the process. Their work and their employees are both top notch."

"it went great. After I called them, I didn't have to wait a long time for an appointment. The gentlemen providing the service was professional and courteous. He didn't try to sell me something I didn't need but made me aware of the overall condition of the roof."

"Did not install or replace my roof, they replaced the backing board and gutters. They did an excellent job and did the job when they committed. There were some nails left in my driveway, but other than that, the job was excellent."

"We could not be happier with our new metal roof! Customer service was beyond reproach and the company's CEO called at the end to ensure we were satisfied with the finished product. We went with the 26 gauge corrugated roof - outstanding product and the installers were able to flawlessly install the panels on a difficult roof (pitch and bump-outs). I, without reservations, recommend Maine Metal Roofing."

Roofing FAQs, answered by experts

After you take steps to determine when your roof was last replaced, you may realize you need a new one. Hiring a roofing contractor you can trust involves asking for references and examples of past work. Verify any qualifications the roofer provides. Ask about the expected time to complete the work and about putting guarantees in writing.

Yes, chimney flashing is an important element in the complex system that is your roof. Chimneys (and anything else that goes through your roof) provide a great opportunity for water damage. Good flashing prevents a lot of potential damage. 

Technically, a flat roof can be raised, but it’s extremely expensive, and there would not be much of a point. Most homeowners raise the roof in their homes to access the space between their existing ceiling and the roof, but flat roofs don’t have this space. Therefore, you can raise a flat roof, but it involves heavy structural modification.

The best way to prevent wind damage to your roof, especially if you live in an area prone to hurricanes, tropical storms, or tornadoes, is to invest in a roofing product with high wind resistance. Look for the ASTM D3161 and ASTM D7158 ratings to see the specific wind speeds your roofing product can withstand. Impact-resistant shingles have the highest wind resistance ratings and will give you the best chance of avoiding wind damage.

There should be small gaps between your roof and the walls of your home, and other buildings. These small gaps let building materials shift, expand, and contract with weather and other outside forces, and they prevent moisture from wicking down walls from roofing and gutter systems. Without these strategic gaps, your home’s exterior and its finishes can sustain water damage, decay, peel, delaminate, and crack. However, there is a fine line between a smart gap and a problematic gap—all  gaps should be small, intentional, and covered or filled in with foam insulation to prevent pests from using them as access points.
