Ask any crew that works San Francisco County and they will tell you the same thing - nothing dries quickly here, so a small leak stays wet. At about 335 miles northwest, Potrero Hill is an easy run for us, inspection or emergency.
You will see our trucks in Mission District, Dogpatch and Bernal Heights on the same run.
A roof opened in winter costs more and risks more, so we plan around the forecast. If a repair solves it, we quote the repair instead of selling a replacement.
You get a start date and a finish date in writing, and we hold them.
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.
One person runs your job and answers the phone the whole way through.
We quote Potrero Hill roofs off what the roof is actually doing, and the weather here punishes details, not products. The shop is about 335 miles northwest, which is why we can be out the same day.
We know Mission District, Dogpatch and Bernal Heights as well as we know Potrero Hill.
The crews fill up fast when the first storm is on the ten-day forecast. The first step is a free look at the Potrero Hill roof and a number you can hold us to.
We do not use subcontract crews we have never met. The people on your Potrero Hill roof are the people we train, and they carry our workers' compensation.
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.
POTRERO HILL, CA TORCH DOWN ROOFING
Yes. The inspection and the written estimate are free, including a second opinion if you already have a quote in hand. We photograph what we find and walk you through it.
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 Potrero Hill 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 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.
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.
For most flat and low-slope roofs in Potrero Hill, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
