Get matched with top natural slate roofing installers and replacers in North Andover, MA

"We are writing to express our sincere gratitude for the outstanding service we recently received. Ranch Roofing installed our roof back in 2012. Fast forward to 2025, when we had damage to our ridge vent, we called Ranch Roofing, and within 10 minutes had a call back from the owner, Bob. He said he would have it looked at and fixed, but to our surprise, in a matter of a few days, he sent his crew, who ripped the entire ridge vent off and replaced it free of charge. We cannot say enough positive things about Bob, his Crew, and this Company. Thank you Bob- Your quick response and generosity are much appreciated! Sincerely, Maryann and Randy D. "

"This company completely took advantage of my MIL with high pressure sales. She did not need her roof redone yet they convinced her she needed it and 30k$ later she has a new roof she didn't need or want. You should be ashamed of yourselves."

"Pro Warrior is one of the last few business run with ethics and character. Fast, reliable work you can depend on. These are the guys that get the job done without any trouble. I’d hire them again and again! "

"With all the snow we got this winter, I did wind up having an issue with an ice dam. I texted John and asked what could be done and he sent over two of his crew and a few hours later the snow was off the roof. "

"I had leaky roof. Of 3 contractors who came to take a look, only Ramon from NMTI pointed out an uneven surface that seemed to be good place to look for an issue. I appreciate hearing specific ideas when there’s a problem, so we chose to work with NMTI. Sure enough, underneath the shingles on that section of roof, there was some water damaged and warped plywood. The NMTI team addressed that and re-flashed some skylights at the same time. The team was all very pleasant. They scheduled the job quickly, once we agreed on details and I would work with them again. Thanks, guys!"

"Very professional and quick. David is a really nice person to work with."
