  Company loves to vandalize the mailboxes by putting on their stickers that cannot come off. Completely unacceptable way of advertising the business

  Excellent business! Honest, hardworking men that worked tirelessly through out the day. Frank always answers or returns your call. He has done work throughout our street over the years. Will do business again. Hopefully in 30 years!

  When it was time to replace my old roof shingles, I felt very anxious because it’s such a big and expensive project. Finding a reliable and trustworthy roofing company was very important to me, and I’m very glad I chose Gamma Roofing. Frank was extremely responsive and came to inspect the roof the same day I contacted him. His quote was competitive, and he used high-quality materials—GAF Timberline HDZ shingles with a 30-year material warranty. He also provided a 10-year labor warranty, which gave me great peace of mind. Frank patiently answered all of my questions. After the materials arrived, he even arranged to start the work earlier because the materials were partially blocking access to my garage. He told me the crew would arrive at 8 a.m. on Saturday, and they showed up exactly on time. The team worked efficiently and professionally. They also cleaned up all the debris around the property before leaving. The workmanship was excellent. I’m truly impressed with the new roof. Thank you to Frank and his crew at Gamma Roofing. I highly recommend them!

  These guys are great and I recommend them 100 % They corrected a problem we had from when our home was built. We had a roof where the roof vents were not to the building code. Roof vents are to be equally distributed on all sides of the building. The original roofer from the builder was so lazy he placed all vents on to only one side of the roof. They modified the layout placing a total of 6 vents equally on both sides of the roof. See attached before & after images of the roof replacement. They were very professional and cleaned the job site so well you would never know they had removed an old roof.
