LOW-SLOPE ROOFS

If you own property in San Francisco, the local conditions decide what your roof needs: fog drip keeps the north side wet long enough to grow moss. From the shop it is a 337-mile run northwest to San Francisco, so emergencies get a same-day answer.
We know Daly City, South San Francisco and Oakland as well as we know San Francisco.
Book in the dry months and the whole job happens on dry decking. The inspection is free, and so is the second opinion if you already have a quote.
We photograph every slope and penetration so you see what we see before deciding anything.
The questions we hear most in San Francisco are about price, timing and whether a repair will hold. We answer all three before you commit, and we put the answers in writing.
When the crew leaves, the debris leaves with them: magnet passes morning and evening, gutters cleared, driveway swept. You get photos of the finished work and the warranty paperwork registered in your name.
We do not use subcontract crews we have never met. The people on your San Francisco roof are the people we train, and they carry our workers' compensation.
Any rot found under the old layers is swapped before anything new goes down.
We work on San Francisco roofs most weeks, and the pattern is consistent: the weather here punishes details, not products. At about 337 miles northwest, San Francisco is an easy run for us, inspection or emergency.
We work the same streets in Daly City, South San Francisco and Oakland, so crews know the area and its roofs.
We would rather find the problem in the dry months and fix it on a schedule. Ask for the inspection, keep the report, and decide in your own time.

Price follows the roof, not a rate card: access, pitch, material, how many layers come off and what the deck looks like underneath. We measure in person, show you photos and put the number in writing before anything is booked.

CLEAR ANSWERS. LOCAL EXPERTISE.
SAN FRANCISCO, CA TORCH DOWN ROOFING
For most flat and low-slope roofs in San Francisco, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
We do. Permits and inspections go through the local building department and we handle the paperwork rather than leaving it to you.
We carry the permits and insurance for hot work, run a fire watch and keep extinguishers on the roof. Where open flame is not appropriate we quote a cold-applied or coating system instead.
A modified bitumen base sheet torched to the deck or cover board, with a white Polyfresko cap sheet over it. The white surface reflects heat instead of holding it.
Installed to spec, twenty years and up, with a manufacturer warranty of 10, 20 or 25 years depending on the system.
Tear-off debris leaves the same day. Driveways are swept, gutters cleared and a magnet pass runs morning and evening, which matters on a street with kids and pets.
Most single-family roofs in San Francisco are done in two to four days once materials are on site. Larger or steeper roofs, or jobs with deck repairs, run longer and we say so up front.
Yes. Panels are detached and reset on a schedule that matches the roofing crew, and the penetrations are re-flashed properly when they go back.
San Francisco sits next to these, and we cover all of them from the same trucks:
We cover Hayes Valley, SoMa, Western Addition, Japantown and Mission District from the same yard as San Francisco. No travel surcharge between them.
