"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."

"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."

"Michael Wright was a phenomenal professional we worked with to accomplish our roof installation project. He was well prepared and knowledgeable, educating us on all their products and services clearly and concisely. No one else in this industry was as transparent and had the paperwork and referrals to back their stellar reputation. I have had some bad experiences with other roofing companies. So, it was immediately clear to me I was in good hands. They even communicated often with us, checking in to see if we had questions and letting us know when the products were going to be delivered. I felt confident and comfortable working with them and I would hire them again when my next roofing project comes up."

"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

Flapping shingles, or shingles that are lifting or curling away from your roof, can be glued back into place using roofing cement or sealant. Apply the glue underneath the shingle, then press it down firmly. You can leave a brick on top of the shingle to hold it in place overnight while the sealant dries.

A gambrel roof and a mansard roof are similar in that they are both hipped roofs, meaning they have double slopes—one steep and one more gradual above the steep slope. The difference is that a gambrel roof has a double slope on only two sides of the structure, whereas a mansard roof has a double slope on all four sides.

You should plan on waiting as long as it takes for the roof deck to dry out completely if it gets wet. In most cases, this will take about 24 hours, but it could take longer if you have shading on your roof or cloudy weather after the rainfall that prevents the sun from drying the material.

Sometimes chimney caps blow off during storms or fall off after rusting away. While this typically won’t cause structural damage, failing to replace a chimney cap can. A chimney cap prevents moisture, animals, and debris from entering your chimney, all of which can cause serious problems, such as damage to the masonry or blockages in the flue.

You only need to replace a roof before moving if it’s extremely old or has more than just a couple minor damages. For instance, leaks, uplifted shingles, or obvious holes are issues no one wants to deal with right when they move in, and will automatically repel potential buyers that might have otherwise been interested.
