We needed a small roof replaced over our front porch before we paint our house. CFY was the first contractor I called, and I got in direct contact with Luis, the owner, first call. The morning I called, he offered to come over right away. When he showed up, he gave me a price on the spot and offered to start on it right away (around 11 AM). His workers just left (6 PM) - finished the roofing project, cleaned up, and all done. Finding contractors this conscientious and responsible is refreshing in San Francisco. I'll use them again, and recommend them to anyone who needs roof work.
