"Communication was good. We had to coordinate with removal of solar panels. We were held up a little bit waiting for a building permit but once that was resolved the install was scheduled a few days later. The crew of 7 arrived at 7 AM and worked non-stop until 6 PM. Completing the entire roofing job from removing the old shingles, replacing some wood and installing the new shingles. They cleaned up the entire work area once done. I would highly recommend them for any roofing jobs you might have."

"Adam Vaillancourt Roofing was the 3rd roofer to inspect my very simple repair job (replacing a single edge shingle) and the estimator (Adam) was the only one of the 3 to offer a repair right away. I hired him on the spot and he completed the job in about 1/2 hour for less than what the others quoted. Very happy with the outcome. Would hire this roofer again."

"Dylan does great work and is professional. Shows up when he says he will. Roof repair well done repared and did work to prevent more water damage. He asked if I wanted him to check my chimney and oh my it was gross dirty with moss and areas where cement feel.out. He fixed it and it looks incredible 😲 Asked him to help with moss and mildew on shed and he has done one treatment and will be back to repeat. He didn't pressure me but asked if I might want to finish reminder of flat roof with the rolled roofing then I would not have to think about it for years. Did not pressure me to do metal roofs as he explained unless I was going to keep house in family not worth the expense.. Thank you for your time. Rachel LaRochelle"

"I recently had my roof repairs done in by Overstate, and I?m pleasantly happy with how everything turned out. I was a little overwhelmed and nervous going into this, but Avi and his team made the process smooth and stress-free. from the free quote to the repairs, it was a really positive experience, and I would absolutely use them again and recommend them to everyone."

"They came to look at the job and determined that there was a condensation issue rather than the skylight leaking. I appreciate their honesty."
