"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"

When my grandfather started roofing, his philosophy of business was grounded in the highest standards and "old time" values: honesty, integrity, and pride. This was a time when these core values were the backbone of America. He knew that a good reputation was much harder to gain than a bad one and the respect and trust of his customers must be earned and re-earned every day. My grandfather’s values upon which Roof Restore was founded have now passed through Three generations. We hope we remain blessed and are fortunate enough to pass them down to future generations. They are the building block of a proud family tradition, the source of our inspiration and the reason for our success. Roof Restore is a family owned company, in operation since 1951. Over the last six decades, we have been serving the residential and commercial owners of Maine. Now, the business has developed from a small dad and son operation to one of the largest roofing companies in Maine .
