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!

GP Martini did a wonderful job replacing the flat roof on our row home this Fall. They were easy to reach and very communicative throughout the process. We felt their pricing was fair. They cleaned up very well at the end and even came back to double check the work and further secure the new roof. I highly recommend this roofing company.
