 Since we opened our doors in 1962, Enterprise Roofing Service has worked  diligently to rise to the top of Northern California's commercial and industrial  roofing industry.

 Over the years, we have installed thousands of roofs, encountering every  conceivable roofing challenge. From the intricate high-tech roofs of Diablo  Canyon Nuclear Power Plant to the acres of roofing on many California malls, we  can do it all.

Enterprise Roofing Service, Inc. was founded in 1962 in Walnut Creek, California. In 1972, we moved into our current facility in Concord, which covers 3 1/4 acres. We have a wide range of equipment, including truck-mounted cranes, dumpster roll-off trucks (with dumpsters), asphalt day-tankers, and a multitude of roof-top equipment.

We specialize in large, heavy specification, difficult projectsWe are a Cal-OSHA registered asbestos roof removal specialist. We have worked from Diablo Canyon in the south (we roofed most of the facility, including the nuclear fuel storage building) north to Ukiah, and to the eastern reaches of Nevada.

We are committed to worker safety. Our goal annually is no worker injuries.

We are very concerned about roof maintenance and have four crews that perform maintenance throughout Central California for many major corporate clients.

Our mission statement is very simple:

                     "Do it right, once, in accordance with specifications, on time, in a safe manner."

                                                                                                                 -- Lawrence T. Reardon, President

Our rock-solid reputation and longevity are a result of hard work and commitment to customer satisfaction. As a licensed, fully insured, professional roofing contractor, we get the job done on time, and we guarantee our work.

We have the experience and versatility you need. Enterprise Roofing Service is your full-service, single-source company for re-roofing and new construction roofing. We are experts in cold- and hot-applied built-up roofing, single-ply roofing and all types of waterproofing.
