We just replaced our 20+ year old roof with GreenTech Roofing. Denis and his crew were a pleasure to deal with. We have had leaks which have destroyed our family room ceiling twice. Each time another roofer attempted to fix it but didn't get to the root of the problem. Denis water tested the roof when he was finished, and guarantees his work for ten years. Our leak worries are over. They also re-insulated our house while they had access, installed an attic fan, and will return to pop in a new shower skylight. They used Plastic Sheeting to protect decks, outdoor furniture, and plants, and were diligent about picking up the little bits of roofing paper that blew further afield into the garden. Denis has a references list and he did share with me. When I spoke with a couple of references they spoke highly of the GreenTech. I'm very happy with their work. If you looking for a good roofing company you definitely have to contact them. You can't go wrong with GreenTech Roofing.

My previous roof was 25 years old, so I definitely needed a new roof. Green Tech Developers was recommended to me by a long time friend who had his roof done 3 weeks before mine. He had personally interviewed 10 vendors and decided on Green Tech. I can't say enough good things about Vlad, inspector/estimator and his crew. Eduardo, his main foreman and his crew worked efficiently and digently and kept the property clean, including my adjoining neighbors. Eduardo informed me every morning and evening of what they purpose to accomplish and what was completed. I highly recommed Green Tech Developers for replacement of roofs.

Having your roof replaced is not something any of us likely rush into. We hired GreenTech because of a recommendation of a friend. The guys were super thorough, fast, and very flexible with timing. We were trying to schedule a roof replacement between rain storms. Great job, Hard workers, Daily clean up. I would recommend using them in any construction projects. They're have all the licenses and insurance, their quality of work and customer service is outstanding.

GreenTech did a fabulous job on replacing our roof and installation of new solar system! Last winter brought a lot of rainy days to San Francisco. Our old roof wasn't able to protect the house from the leaks any longer. Finding a roofing company that could start the project within a week was really hard. We are so lucky, our friend recommended GreenTech. The entire team is over the top in terms of quality, attention to details and thoroughness. My roof was completed with all new shingles, gutters, and new Solar System within three days. These guys do great work. No surprises.
