I had them replace my roof in 1998. Never had a problem and roof still holding strong.

I wish I could give zero point to this company. Avoid them at all cost!!! If you have a problem with the installation, they will leave you hanging. We had Robert Green Roofing replace our old rotted wood gutters some years ago. They also replaced some old, equally rotted fascia board at that time. Unfortunately, the new gutters never worked properly. The corners have always be leaky, and during heavy rain the gutters don´t drain fast enough and overflow. At one area it is so bad, that the water leaks into our sun room. I have tried to contact the company multiple times to address and fix the problem, but I can never reach a live person. I have left dozens of messages on their answering machine, and I never had someone call me back. EXCEPT for my last try, when I said I was interested in installing gutter covers... next day I had a call back. When I mentioned that there are also some things to be fixed on the existing gutters the guy, I believe it was Robert Green himself, told me that they will call me back to schedule... and that was the last thing I heard from them. They are eager to sell, but don´t stand up to their work. AWEFUL, AWEFUL COMPANY!!!
