Customer Testimonials

Reviewer photo
Karl was wonderful through the whole process. My husband and I were very impressed with how the roof was going to be installed -- my husband is a tradesman. GP was on-time and the when Karl said he or his crew would do something, he always followed through -- so refreshing. Thanks to Bob, the foreman, our roof replacement was quick, efficient and looks beautiful!! The crew was so thorough and around my house was cleaner than when they started!! SO happy we went with GP Martini!!!

Roof looks great. Much improved. Felt the price with the warranty is fair. I found nails in my lawn after which was a hazzard with the kids. Overall very satisfied.

I've been having Gary Martini do exterior work on our house for MANY years. He and his crews are very professional and do a terrific job. I highly recommend GP Martini Roofing.

The work was not completed in one day. The roofing work was completed the next morning but the gutter covers have not been done and we have not heard from the salesman when it will be.
