"I was totally satisfied with the roofing project. I got 3 bids and this company's proposal was the most cost effective. It was also right in line with my cost expectations due to other roofing projects that I had done elsewhere. He also kept in touch with me as to timing as roofing shingles had some delivery issues due to the pandemic. Once he started, his crew was in and out in a single day with no disruptions to me. Upon inspection, it was a thorough job and I've very satisfied and will reach out to the company for other projects. I highly recommend Jalbert Contracting."

"Kevin and his crew showed up early and got right to work. Finish product is looking great. There was a small issue with a few of the baffles in the attic not being secured correctly and Kevin took care of it quickly. Would definitely recommend JP Carroll."

"Really needed a new roof after this winter. These guys were knowledgeable and got me on their schedule relatively fast. Workmanship was high quality and the crew was extremely professional. Absolutely will call again when it is time to replace my siding."

"Having reached out to several roofing contractors I found the initial team (Steve quoted the job and Mark who is the owner) to be knowledgeable, extremely professional and competitive with the price. After signing the agreement I was assigned a representative (I was in contact with Paul) and he kept me updated on the timing of shingle delivery, dumpster and when the crew would be onsite to work. The work was completed within the timeframe they quoted and was done well. The roof looks great and they made sure the area around the house was left spotless without bits of shingles or nails. I would definitely hire them again and feel comfortable recommending them as a quality roofing company."

"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 FAQs, answered by experts

Copper roofing works well in all kinds of climates, but it’s ideal in humid climates because it naturally repels fungus, moss, and algae. This makes it one of the best roofing options for Cape Cod homes in the Northeast, as well as homes in the humid southern states and snowy northern states. That said, copper is vulnerable to thermal expansion. If you live in a climate that has extreme temperature changes, your contractor will need to consider this during the installation process.

DIY is not recommended, as slate requires specialized handling and proper underlayment installation for durability.

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.

It’s possible to walk on a clay tile roof, but you run the risk of breaking or cracking the tiles if you’re not careful, so it’s best not to walk on it if you can avoid it. If you or a contractor needs roof access, be sure to distribute your weight evenly and step on the portions of tile that are also supported underneath, which depends on your tile design. Walking on any roofing material is inherently dangerous, so wear rubber-soled shoes and use safety equipment if you need to access your roof.

The short answer is, yes, cedar shakes do last longer than asphalt shingles. But the long answer is, it depends on maintenance. Asphalt shingles last about 20 years, while cedar shingles typically last about 30 years with proper maintenance. If they are very well maintained and installed in an area with a mild, drier climate, they can last up to 50 years.
