About Us

Mark Powers Mark Powers
President

I have been with Excelsior Roofing Co. since 1972. My day to day job is returning all phone calls, setting up all jobs, communicating with foreman every morning, ordering all material, all questions that arise prior, during, and after any job. Any negotiating for insurance and all the legal business related items.

I feel that anybody who hires Excelsior Roofing Co. is getting the absolute best of what San Francisco has to offer. We are without a doubt experts in our craft, which can also include problem solving. Due to our longevity, we have distinct opinions about what you’re best options should be. We welcome the opportunity to serve you.

Monica is the behind the scenes person that puts all our bookkeeping, estimates and overall office needs in a great orderly fashion. The speed that we are able to get your information to you is all due to Monica.

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.

Sincerely,

Mark Powers
President
