"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."

"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."

"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!"

Customers say: Terrific value

"A portion of the ridge vent on my roof lifted up during a heavy wind storm Monday. Dwayne responded at 9am Tuesday and was here by noon and tacked the vent down to close up the roof. He was scheduled to replace the vent on Thursday but came today(Wed) and is up on the roof now because there is snow coming in later today and he wanted to make sure the repair was completed before then. I couldn't have asked for better service. Thank you Dwayne! Marcia Burley"

Roofing FAQs, answered by experts

If your roof has a vapor barrier, you will need approximately one square foot of roof vent for every 300 square feet of ceiling space. If there is no vapor barrier, the roof should have one square foot of roof vent for every 150 square feet of ceiling space. If you are not comfortable making this determination, a local roofing professional can help.

Fall is generally considered the best time of year for roof repairs. The weather is temperate and typically drier, which makes for safer working conditions and fewer delays. The days are also still long enough to complete the work.

Spring is another good option and is a popular time for repairs to fix damage from winter storms. However, frequent rainfall can slow down progress. Spring may be a less busy season for roofers than fall.

Summer can also work for roof repairs, but extreme heat can make asphalt shingles too soft and difficult to work with.

The most common slope range for roofs on houses in snowy areas is between 4/12 and 6/12, or 50%. A roof with a slope of less than 10%, or roughly a 2/12 pitch, won’t be effective at shedding snow. However, roofs that are too steep can allow large amounts of snow to build up and fall all at once, creating a hazard for those on the ground.

Properly maintained roof decking can last between 20 and 30 years on average, though it varies based on a few factors. Mainly, the quality of roof decking materials and environmental conditions have the most impact on longevity. You can extend its lifespan by regularly inspecting your roof and making repairs as necessary.

You can walk on a TPO roof, but you should only do so when necessary and wear footwear that’s less likely to puncture the surface. If you anticipate needing to frequently walk on your TPO roof, reinforce walkways to protect against punctures. TPO roofing can also be slippery, so in most cases, you’ll want to leave walking on it to the pros.
