GP Martini Roofing replaced our old shingle roof on our detached garage with a beautiful metal roof and a new cupola—and the results exceeded our expectations! From start to finish, their team was professional, responsive, and highly communicative. They completed the project on time and followed our exact specifications.

Wow. How rare was this? The price that was quoted was the price I paid. The day they told me that they showed up, they showed up! I was told the job would be done in one day - and it was done in one day. I could not be happier. Fast, clean, efficient. Top grade material, excellent warrantee. Oh, and they have a zero interest for 12 month program offered through a leading bank. Free money! I'd recommend this company to anyone. They did an outstanding job!
