LOW-SLOPE ROOFS

Every town in San Francisco County treats a roof a little differently, and fog drip keeps the north side wet long enough to grow moss. From the yard it is roughly 338 miles northwest to Nob Hill - no travel surcharge, no week-long wait.
Neighbouring work in Russian Hill, Chinatown and Pacific Heights means materials are already staged nearby.
The crews fill up fast when the first storm is on the ten-day forecast. If a repair solves it, we quote the repair instead of selling a replacement.
Weather delays are called early rather than left to surprise you.
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.
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.
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 Nob Hill tightens fast, and emergency work costs more than planned work.
Synthetic underlayment goes down over the whole deck, not just the valleys.
Before materials come into it, the site decides the job: in Nob Hill, salt air and long damp mornings keep fasteners and flashings working hard. We are 338 miles northwest of Nob Hill; crews pass through most days anyway.
You will see our trucks in Russian Hill, Chinatown and Pacific Heights on the same run.
The crews fill up fast when the first storm is on the ten-day forecast. We will tell you if the Nob Hill roof has years left in it rather than sell you a new one.
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.
The questions we hear most in Nob Hill are about price, timing and whether a repair will hold. We answer all three before you commit, and we put the answers in writing.
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.
Everything below is the same crew, same city, same free inspection.

NOB HILL, CA TORCH DOWN ROOFING
Most single-family roofs in Nob Hill 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.
For most flat and low-slope roofs in Nob Hill, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
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.
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.
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.
Installed to spec, twenty years and up, with a manufacturer warranty of 10, 20 or 25 years depending on the system.
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 Nob Hill property, measure it and put a detailed number in writing before anything is booked.
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.
