"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 would not recommend them. Initially it appeared they did a good job on my rubber roof, so I hired them again for full gutters, which they subcontracted out. Within the year I had a large leak develop behind their new gutter. They acknowledged the problem but it took months, and constant badgering by email and phone, to get them to come back and fix the problem. They tried a temporary fix with sealer, which failed in weeks, and then it took weeks longer to get them to come back and install a fascia apron. The next year, my rubber roof leaked where they had flashed it. Again it took months to get them to come back and look at it, with constant badgering. When they came back they applied a copious amount of sealer and told me that I had a rot problem with a wooden railing that I would need a carpenter for, and that they would send me photographs and suggestions for repair. They never replied after that, and the leak continued despite their sealing attempt. I finally gave up and found a new roofer, who tells me that they did an inferior job in the first place, and the repair is costing me thousands of dollars."

"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."

"Jake and power did a top job with my window install. He was incredibly pleasant to talk to. The presentation inspection was helpful to get me started. Jake gave me sound advice with what should be done before i put the house on the market. The crew worked hard in the cold to finish the install in one day. They look great! I highly recommend!"
