Thank you for considering Excelsior Roofing Co. for your re-roofing project. Excelsior Roofing Co. is San Francisco’s oldest roofing firm. We have been family owned and operated since 1906. Mark Powers has been an employee since 1972 and became owner in 1983, the same year Excelsior Roofing Co. incorporated. An active foreman is on site, overseeing all jobs. Mark Powers inspects most jobs on a daily basis.

We are proud to represent a Union shop that employs, on average, fifteen men, all members of Roofers Union Local 40 S.F.. All our men have obtained, or are undergoing, a three year State approved apprenticeship training program. We also are active in keeping current with safety practices and standards.

All materials used are of high quality, which are stored in our warehouse, bought and paid for prior to re-roofing your property.

We are proud to be members and supporters of the following roofing associations: Associated Roofing Contractors of the Bay Area Counties, Western States Roofing Contractors Association, The National Roofing Contractors Association, and the Better Business Bureau.

Excelsior Roofing Co. has been featured by local television and newspaper publications. We remain available to all press, television and radio.

We are an 80% residential, 20% commercial re-roofing company. We are considered experts in leak detection and try to take a common sense, rather than an aggressive, approach to roofing problems.

Many items in the following pages are meant to be helpful to the customer regarding questions and concerns.

If the homeowner accepts the bid, a proper and formal contract (per California State Contractors License Board) will be sent. A deposit may be required (not to exceed $1,000 or 10 percent of the contract price, whichever is less), usually $500.
