The short version for Hayes Valley: the weather here punishes details, not products. From the shop it is a 337-mile run northwest to Hayes Valley, so emergencies get a same-day answer.
We work the same streets in SoMa, Western Addition and Castro, so crews know the area and its roofs.
Dry-season work books up fast, so the calendar tightens once the first storm forecast lands. Expect photos, a measured scope and a number you can compare against anyone else.
Soft decking gets replaced, not covered - we quote a sheet count and show you the bad bays.
A roof is a system. The membrane or shingle gets the attention, but the underlayment, the fasteners, the edge metal and the ventilation decide whether it reaches its warranty.
Dry-season work is cheaper and safer, because the whole job happens on dry decking. Once the first storm is on the ten-day forecast the calendar in Hayes Valley tightens fast, and emergency work costs more than planned work.
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.
Warranty paperwork is registered for you, not left in a folder for you to chase.
The job list in Hayes Valley repeats itself for a reason - whatever fails first on these roofs fails at the edges. We cover Hayes Valley from about 337 miles northwest, close enough for emergency calls.
Jobs in SoMa, Western Addition and Castro run alongside this one most weeks.
We would rather find the problem in the dry months and fix it on a schedule. The inspection is free, and so is the second opinion if you already have a quote.
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.
Cheap work shows up at the details: a flashing sealed instead of replaced, a vent reused because it was quicker, decking covered because nobody wanted the conversation. Those are the roofs we get called back to in two winters.
Dry-season work is cheaper and safer, because the whole job happens on dry decking. Once the first storm is on the ten-day forecast the calendar in Hayes Valley tightens fast, and emergency work costs more than planned work.
Everything below is the same crew, same city, same free inspection.

HAYES VALLEY, CA TORCH DOWN ROOFING
Most single-family roofs in Hayes Valley 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.
You get the manufacturer warranty on the materials and ours on the workmanship, both in writing. The paperwork is registered for you and transfers if you sell.
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.
Yes, licensed, bonded and insured, with workers' compensation on every crew. Certificates are available before work starts.
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.
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.
Installed to spec, twenty years and up, with a manufacturer warranty of 10, 20 or 25 years depending on the system.
For most flat and low-slope roofs in Hayes Valley, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
