"1. punctual on estimate appointment 2. three estimates were solicited all were equivalent service for product two allowed for Owens Corning or GAF and were certified as was On Top 3. The date proposed was mid October but the actual work was much sooner (low slope roof) and completed in several hours The roof has now gone through several seasons without issue. I recommended them to a friend of my wife"

"Excellent! Kevin was very responsive and came by just a few days after I had requested an on line quote. He gave me a proposal with the full price and explained everything and there was no sales pressure at all. A week later he came by again and we signed the proposal and gave him a deposit. He had shingle samples and again explained the process and answered all questions. A week later a crew was at our house right at 7:00 AM and were stripping the roof by 7:30 AM, after covering the bushes and hanging down tarps from the roof to protect the house. They were all done by 4:30 - cape style house and two car garage. The crew did a great job, the roof looks great and everything was cleaned up. Kevin came by and did his visual examination and to make sure everything was OK. Great Job!"

"the work was great, he went in their and cleaned up everything, and put in a piece of pad to cover it to keep the birds out; he also checked every part of the roof for any possible entries as well."

"I can’t say enough good things about Evans Roofing! My husband and I met with Dan who listened to every detail about our project replacing our very old roof and gutters Within a few hours that same day Dan sent us a very reasonable quote to do both roof and gutters. Within 1 week the roofers were here and the roof was done in 1 day Day 2 our gutters were done The clean up was fantastic! They left the site cleaner than before they were here!! The crews were professional, polite and very kind . We did meet with another Roofing Company prior who gave us a long sales presentation and quoted us 3 times the cost to do the same job but I won’t go there because I want this review to shine for a Evans Roifing! So if you have a roofing job and gutters done go with the compnanyvthat fits your needs but please consider Evans first Thank you Ps I wish I could show pictures but can’t figure out how ☺️"

"Lifetime Roofing is an outstanding contractor. The work was excellent, the price was fair and their communication was exceptional. After a heavy rainstorm, water was leaking into my house. Paul from Lifetime Roofing got back to me very quickly and, after an inspection, recommended that the flashing be replaced in one area of the roof. I was impressed that Paul kept in constant email contact through the contracting and scheduling process, answering all my questions. The crew was professional and skilled and completed the work in one day and did a terrific job. After the work was completed, Paul even followed up after a rainstorm to make sure no water had leaked into the house. None did. It was a very positive experience and I highly recommend this company. I will be using them for all my future roofing needs."
