  • “They put on a brand-new roof, and I was astounded by how much they did in one day. By noon the old roof was gone, and by the end of the day there was a beautiful new roof! There was no mess, it was like they were never here!”

  • “I’ve used Excelsior on two different occasions— to refurbish a roof and to do some repair work around the edges. They are professional, arrive on time, and are polite and clean. They have a lot of experience. I’m very happy with their work.”

  • “Mark’s been doing maintenance work on my home for about 30 years, and his father before him for about 20 years. I have them come out every couple of years just to make sure that nothing needs repair. ”

Finding a good, reliable roofer in San Francisco isn’t easy. Over the past few years, hundreds of new companies have sprung up, offering amazingly low prices and long guarantees. Unfortunately, the Department of Consumer Affairs reports that roofers have one of the highest complaint rates of any industry.

So how do you choose a roofer? One way is to deal with long-established companies. Roofing is a high-overhead, low-margin business: only the well-run, reliable companies can survive.

Family-owned Excelsior Roofing has 98 years of experience roofing San Francisco homes, and are known for their quality, honesty and reliability.

San Francisco’s oldest roofing company, Excelsior Roofing is managed today by the founder’s grandson, Mark Powers, who has acquired enormous expertise in his own right after roofing for over 30 years in the City. Mark keeps Excelsior’s prices competitive by buying materials in bulk, and warehousing them. Jobs are bid individually, and billed on completion.

“We don’t use scare tactics, or hard-sell techniques,” says Mark. “My job is to educate you on on all different roofing types, and what is going on with your roof, so that you can make an informed decision that fits your needs.”

Excelsior specializes in residential and commercial roofing: built-up (tar and gravel) roofs, shingles, tiles, slate and all roof-related sheet metal work. Each Excelsior employee has completed a full apprenticeship, and receives continuing education through the Roofers’ Union. Most have been with the company over 10 years.

All jobs are checked daily by crew supervisors. Customers are protected by one million dollars of general liability and accident insurance, with Excelsior Roofing Co.’s workmanship on new roofs guaranteed for five years.

Estimates are free.
