"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."

"Without hesitation, we recommend Len Gibley Contracting. Three years ago, we hired them to replace our roof and were very satisfied with the work, price, cleanliness, and timeliness. So, when it came to our siding and window renovation, we included them in the bidding process. Brian Dobbins was very responsive from start to finish. During the bidding process for Hardie Siding, Andersen Windows, gutters, and porch and deck repairs, Brian listened well, offered solid solutions, and gave us a competitive and detailed proposal. During the renovation, he was there to answer questions and solve problems. Brian's professional and hardworking crew showed up daily through completion. They finished on time and budget with no surprises. We are thrilled with the quality of the materials and installation, and we're glad we made a significant investment with Len Gibley Contracting. Thank you, Len Gibley - Our house looks brand new!"

"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

The formula for calculating how many squares of roofing you need is pretty easy. Take the total amount of square footage and divide it by 100. With this formula in mind, a 2,000-square-foot roof would require 20 squares of roofing material to adequately cover it.

Roof raking can damage shingles if improperly done. Be sure to use a rake that’s designed specifically for removing snow from a roof, and don’t use excessive pressure. Light, consistent pressure to pull down the bulk of the snow is all that’s needed—if you clear right down to the shingles, you’re probably using too much force and risking roof damage.

Homeowners insurance sometimes covers roof decking, but it depends on the cause of damage and whether the decking was properly installed. If the roof decking was damaged by a severe storm, then it will likely be covered. Insurance may also pay for roof decking work if building codes require it. However, insurance won’t cover damage caused by normal wear and tear or poor maintenance practices.

Clay tile roofing is common for traditional villas, while flat roofs are more standard for modern villa homes. Clay tile roofs are long-lasting, require little maintenance, and are great for warmer climates. Flat roofs are usually low-cost, energy-efficient, and allow for rooftop gardens. 

Some homes, like those with flat roofs, may not have eaves at all. Some contemporary-style homes also lack eaves, although many may have abbreviated eaves to divert water and protect the walls and foundation. Homes without eaves often have specific types of gutters affixed directly to the edge of the roof to provide adequate drainage.
