"JPCarroll did a fabulous job on replacing my complicated, decrepit Victorian roof, completing it in a timely way and against adversity – they did the whole thing in the month of January in freezing temperatures and sometimes snow and ice. I interviewed five other roofers. However, their sales person took more time and provided far more specificity than any of the other others. Their bid was not the cheapest but turned out to be the best value by far. They went the extra mile to resolve many unforeseen problems, and the quality of work was high. Everyone I dealt with, owners, staff, and laborers, were courteous and responsive throughout. The job supervisor, Kevin, was thoughtful and included me on numerous decisions. Luke Carroll, production coordinator for the job, was always available to help, as was everyone else, even on weekends. They coordinated well with my carpenter, replacing a significant amount of trim, siding, and more as a team. The people doing the actual labor worked"

"OTB was great to deal with. Wind storm ripped half the shingles off of my garage, Chris came out the next day to give me a quote. Price was excellent and the job was done a week later. His contractor was well informed and professional, and left my home looking better than ever. I would highly recommend using them for any project."

"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."

Small jobs welcome

"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

Chimney crowns are located above the final brick layer at the top of a chimney. It’s important to get regular chimney maintenance and inspection, because it is near impossible to spot chimney crown damage without getting on your roof.

Removing snow from your roof can help prevent ice dams, but the best thing to do is address insulation issues in your attic. If you do decide to remove the snow manually, you should always use a roof rake rather than a shovel. You shouldn’t climb your snowy roof in any circumstance, and roof rake allows you to remove the snow from the ground or a ladder. For the best results, remove snow as soon as possible after it falls.

Flat roofs are a solid option for people who want extra outdoor space. Flat roofs are very common in other parts of the world and only recently has the U.S. started to see the benefit in the increased space. Flat roofs are also easier to maintain and pose much less of a safety risk, which allows for more DIY work for handy homeowners. Some people also build green or living roofs that grow plant life. 

Roll roofs don’t last as long as traditional roofs, like those made of asphalt shingles. A roll roof typically lasts between five and 15 years, whereas a shingled roof will last between 20 and 50  years. Modified bitumen roofs are similar in look to rolled roofing but have a 12 to 15 year warranty.
