Customer Testimonials

Karl B was the best. He was super personable and humorous. He gave me all the information I needed to make an informed decision. The staff was on time and for the job done in a timely manner. I would fully recommend them for anyone who is seeking an excellent roof repair or replacement.

Good communication. Job was messy, party due to wet ground and snow. Crew will hopefully be back to clean up as promised. Lots of debris in garage and on car inside garage and garage door chain seems to have been knocked loose. Would have preferred to move car out if I knew about the debris. Still need to inspect car more closely for any damages. .

It was seamless starting with Ryan educating me about the roofing material, the process and his follow up the next day. The only issue we had was when leaving our house when the job was done, one of the trucks sideswiped our mailbox and bent it sideways. I was able to straighten most of it and let Ryan know. All in all I would heartily recommend GP Martini when a new roof is needed

GP Martini was very responsive to a minor problem with the roof installation. Everything was corrected in short order. I am very satisfied!
