LOW-SLOPE ROOFS

Every town in San Francisco County treats a roof a little differently, and the marine layer holds moisture on the roof well past sunrise. From the yard it is roughly 338 miles northwest to Japantown - no travel surcharge, no week-long wait.
The roofs in Western Addition, Pacific Heights and Hayes Valley are built much the same way, and they fail the same way.
Summer is for planned work; winter is for emergencies nobody planned. Expect photos, a measured scope and a number you can compare against anyone else.
The written warranty names what is covered and for how long, with no asterisk games.
Before we quote we check the deck, the ventilation, the flashings and the drainage. Three of those four are invisible from the ground, and all four decide how long the roof lasts.
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.
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.
Most homes take two to four days once material lands.
Roof life in Japantown is decided by exposure more than brand, and sea air corrodes anything unprotected and keeps north slopes damp. We cover Japantown from about 338 miles northwest, close enough for emergency calls.
Crews rotate through Western Addition, Pacific Heights and Hayes Valley, so the drive is routine.
We would rather be on your roof in September than during the first atmospheric river. If a repair solves it, we quote the repair instead of selling a replacement.
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.
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 Japantown tightens fast, and emergency work costs more than planned work.

CLEAR ANSWERS. LOCAL EXPERTISE.
JAPANTOWN, CA TORCH DOWN ROOFING
We do. Permits and inspections go through the local building department and we handle the paperwork rather than leaving it to you.
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.
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.
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.
Cost depends on the size and pitch of the roof, the material you choose, how many layers come off and what the deck looks like underneath. We inspect the Japantown property, measure it and put a detailed number in writing before anything is booked.
Installed to spec, twenty years and up, with a manufacturer warranty of 10, 20 or 25 years depending on the system.
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.
For most flat and low-slope roofs in Japantown, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
