GP Martini did an outstanding job on our home. They are more than just siding and roofing, and they proved that with the project on our home.

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.

Like many others, we were more than satisfied with GP Martini's work. They showed up on schedule, stripped the old roof within hours, and collected most of the debris before it hit the ground or damaged any plants. Our house is not large, but we were still surprised that the new roof was completed the same day and any loose roofing nails were rounded up with a magnetic device. I don't believe we found more than two such nails in the year following the installation. Their work... impressive.

We had our roof done a few years ago. They were great to work with . Very fast, impeccable clean up after the job. The final product looks great.
