Customer Testimonials

The worth experience with contractors and very unprofessional, disrespectfull. After installation of the roof it was leaking. 30 years warrenty just a joke they would find any exuse, any possible reason not to fix it. They Don't respond to the phone calls. Please never use that company!

Ryan is very professional and accommodating with my schedules. Dave and his team is very prompt and skilled. They care my property and did thorough cleanup afterwords. I will strongly recommend GP Martini to friends and families without any reservation.

damaged our AC unit by not covering it up when throwing old shingles off the roof. When putting new shingles on they were not going to replace a moldy piece of wood. I had to point it out to them and they don't understand english so that was another issue. They didn't put in the right skylight in so we never got the blind that we requested. I could go on about all that went wrong, but it would be long. Bottom line...DON'T WASTE YOUR MONEY ON THEM!
