Mark Simpson got his first taste of the roofing industry when he was a teenager. Life intervened, and after college he spent several years teaching biology and chemistry. His interest in roofing was rekindled when he moved to the Bay Area, and he began working as a roofing estimator with a construction firm. In time, his entrepreneurial spirit motivated him to go into business for himself. Today, Mike Simpson and Simpson Roofing Service offer the expertise of 40 years of industry experience. .

That experience is critical! You'll want a roofing contractor who has plenty of familiarity with installing the type of roof you need. Simpson Roofing Service is a veteran of complete roof construction for a wide range of popular roof types. Because they invest time up front to understand your needs, they can provide a thorough, accurate estimate. They take responsibility to obtain any necessary building permits. The company is insured, employees are bonded and everyone makes safety (yours and theirs) their first concern.

A roof is a very big investment. Don't trust yours to the first name you come across in the phone book. Call Simpson Roofing Service. If their beautiful work doesn't convince you, the glowing recommendations from their customers will.

Owner Philosophy

"Quality work is all about paying attention to detail. We check our work, re-check it, and then check it again. We also enjoy educating the customer on all their options. We listen to what the customer wants, communicate with them throughout the project and follow up afterwards. There’s absolutely no excuse for any customer being anything but completely happy.”
