LOW-SLOPE ROOFS

What a roof faces in Potrero Hill is specific, not generic: the marine layer holds moisture on the roof well past sunrise. Being 335 miles northwest of Potrero Hill, we can be on the roof before the next rain band arrives.
Jobs in Mission District, Dogpatch and Bernal Heights run alongside this one most weeks.
The crews fill up fast when the first storm is on the ten-day forecast. Nothing is booked until you have photos, a scope and a written price.
Workmanship coverage is ours to honour, and we are still here to honour it.
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.
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.
Underlayment is where corners get cut; we use the system the manufacturer warrants.
Roof life in Potrero Hill is decided by exposure more than brand, and nothing dries quickly here, so a small leak stays wet. We are 335 miles northwest of Potrero Hill; crews pass through most days anyway.
Crews rotate through Mission District, Dogpatch and Bernal Heights, so the drive is routine.
We would rather be on your roof in September than during the first atmospheric river. We will tell you if the roof has five years left, because that is also useful to know.
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.
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 Potrero Hill tightens fast, and emergency work costs more than planned work.
Everything below is the same crew, same city, same free inspection.

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.
