Are you patching the same leak every rainy season? When a roof is at the end of its life, another repair often costs more than a planned replacement. Roof By Tom replaces residential and commercial roofs from San Jose through the East Bay and San Francisco.
We tear off to sound wood, install quality underlayment, flash every pipe and chimney, and leave your property swept. You get a written scope, a schedule, and a crew that works while you stay in the house.
If this is the work your home needs, call (925) 722-6494 or send the form for a written estimate. There is no obligation.
How to know it is time to replace your roof
Widespread granule loss, more than one active leak, a roof past its expected life, or a second layer already on the wood usually point to replacement. We say so only after we inspect. If a local repair will hold, we recommend that instead.
What a Bay Area roof replacement typically costs
Many asphalt shingle replacements in the Bay Area fall between about $9,000 and $28,000. Size, pitch, stories, material, and access change the number. Tile and metal cost more. We measure your roof and price the job in writing before we start.
Roof replacement permits and how long the job takes
Most cities require a permit for a full replacement. We pull it when the city asks and schedule around the inspection. Most homes finish in one to three days once materials are on site. Financing is available if you want to start now and spread the cost.

Roof replacement questions
How do I know it is time to replace, not repair?+
Widespread granule loss, multiple active leaks, a roof past its expected life, or a second layer already on the wood usually point to replacement. We recommend that only after we inspect. If a defined repair will hold, we say so.
How much does a new roof cost in the Bay Area?+
Typical asphalt shingle replacements often fall between $9,000 and $28,000, depending on size, pitch, access, and material. Tile and metal cost more. Your written estimate is based on a measurement of your roof, not a phone guess.
Can I stay in the house during the job?+
Yes. We protect walkways, keep a clean drop zone, and work so you can live around the project. Most homes are livable the whole time.
Do you pull the permit for a new roof?+
Yes, when the city requires one. Most Bay Area replacements need a permit. We pull it, build to the inspection, and keep you posted on the schedule.
