"Long Roofing went above and beyond when installing our roof and gutter. The job turned out more difficult than we thought it would be but Long Roofing made me feel comfortable and reassured that they would fix everything. Everyone involved from the salesperson to customer service listened to our needs and treated me with respect. The roof looks amazing. I don't want to get into price, but even though you may get someone less expensive, using Log Roofing was well worth a little extra cost"

"Chris and Aaron worked with us to help figure out where the mildew smell was coming from. We just bought a house and the back bedroom smelled awful. They replied to our request for an estimate ASAP. We couldn't be happier with the service I received from them! We had some damaged siding and a leaky window that needed immediate attention. They responded quickly, assessed the situation thoroughly, and provided a clear, affordable estimate. Being a local company, they were able to schedule the repairs much faster than other companies I contacted. The work itself was top-notch; the siding looks seamless, and the window is now perfectly sealed. What truly impressed me was their trustworthiness. They were honest about the necessary repairs, didn't try to up-sell anything, and kept me informed throughout the entire process. If you're looking for a reliable, affordable, and talented siding company, we highly recommend them!"

"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."

"Called Adam Vaillancourt Roofing to fix a leak in our roof based on their consistently high customer satisfaction ratings. We met with sales rep Jose Luna, who conducted a thorough inspection and found the leak easily. His presentation about the company and how they do their work was impressive and Jose was very professional and included a video that Jose shot while on our roof in which he explained not just the issues that were found but WHY the work was needed. He never pressured us into agreeing to anything. We signed a contract immediately. Fast forward a few weeks later and Paul Camarro and his crew showed up at the house on time and ready to work. When they were done, Paul showed us photos of the completed repair work, so I knew they delivered as promised. We will absolutely be calling Vaillancourt in a few years when our roof needs to be replaced. Highly recommend!"

Roofing questions, answered by experts

How long shingles last depends on the type of shingles you have on your roof. Asphalt shingles normally last anywhere from 15 to 30 years, metal shingles can last anywhere from 15 to 100 years, and tile shingles can last anywhere from 50 to 100 years or more.

The common formula for measuring a roof is length x width equals square footage. Professional roofers measure the length and width of your roof, including dormers, and determine its pitch and rafter sizes. If a roof surface is a triangle, they’ll divide that square footage by two, then add up the square footage of each surface to get the total for the roof.

The roof overhang, also known as the eaves, does count as part of the roof’s square footage because it must be covered with the roofing material. The overhang is one of the reasons why you can’t base your roof's square footage on the square footage of the house. The roof square footage must also account for the pitch of the roof as well as the eaves.

While you technically can add a roof over shakes or shingles, it’s not a good idea. Roofing over existing roofing creates a moisture barrier underneath the new roof and since the trapped material is wood, you can expect a moisture problem. While you could get away with installing a new roof over asphalt or steel, wooden roofs should be removed, new underlayment installed, and the new roof installed over that. Also, the extra weight would add strain to your roof structure.

Asphalt shingles blister when air gets trapped between building materials, either within the layers of the shingle itself or in adhesives on the undersides of the shingles. As the roof heats up in direct sunlight, the trapped gas expands and creates a bubble in the roof. Eventually, the bubble can pop, leaving an exposed area of decking and underlayment.
