Torch Down Roofing
Two Plies, Welded Seams, No Guesswork.
Torch down roofing in SoMa is modified bitumen, installed in two plies and heat-welded as it goes down: a base sheet torched to the prepared deck or cover board, then a white Polyfresko cap sheet over it. The seams fuse instead of relying on adhesive, which is why the system holds up on flat and low-slope roofs that see standing water.
All American Roof Repair & Commercial Roofing installs and repairs torch down on houses with flat sections, apartment buildings, HOA property, offices and light industrial across SoMa, Tujunga, Shadow Hills, Lake View Terrace and the northeast city.
Why Flat Roofs in SoMa Fail
SoMa sits in a bowl at the foot of the Verdugo and San Gabriel Mountains and it bakes. A dark flat roof here runs far hotter than the air, the daily swing works every lap, and the fall winds drive grit across the surface. Then the rain arrives in short, heavy bursts and finds whatever the summer loosened: a split lap, a lifted edge, a drain that has not been cleared since the last storm.
How We Install It
Tear-off and deck check
The old roof comes off and any soft decking is replaced before a new sheet touches it. You see the bad bays before they are covered.
Insulation or cover board
Where the building wants R-value, polyiso goes down; otherwise a cover board gives the torch a sound, even surface.
Base sheet
The modified bitumen base ply is torched and rolled so the whole sheet bonds, not just the edges.
Polyfresko cap sheet
The white cap ply goes over it, seams welded and probed. White means the roof reflects heat instead of storing it.
Flashings and drains
Curbs, pipes, parapets, edge metal and drains are detailed last, because that is where flat roofs actually leak.
Torch Down vs the Alternatives
- Against a patch. Patching buys months. A two-ply system is a roof, with a manufacturer warranty behind it.
- Against TPO. Both work on flat roofs. Torch down suits smaller, cut-up roofs and buildings with lots of penetrations; TPO suits wide open spans.
- Against a coating. A coating renews a sound roof. If the deck or insulation is wet, torch down replaces it instead of sealing the problem in.
- Against built-up. No kettle, no gravel, and a white surface rather than black asphalt cooking all afternoon.
Straight talk: torch down is hot work. We carry the permits and insurance for it, run a fire watch and keep extinguishers on the roof. Where open flame is not appropriate — a wood deck in poor condition, an occupied building with tight access — we quote a cold-applied or coating system instead and say why.
What We Roof in SoMa
If the roof is flat or low-slope, torch down is on the table:
-
Homes with Flat Sections
Additions, garages and mid-century flat roofs where shingles were never the answer.
-
Apartments & HOAs
Staged section by section so tenants stay put and the lot stays usable.
-
Commercial Buildings
Offices, retail and light industrial, scheduled around your hours.
-
Low-Slope Roofs
Shallow pitches where water moves slowly and details decide everything.
Before and After
The same roof, cracked and ponding, then two plies down with a white cap sheet.
Warranty and Lifespan
Installed to spec, a two-ply torch down roof runs twenty years and up, and the manufacturer warranty is written for 10, 20 or 25 years depending on the system we specify. The paperwork is registered in your name, not left in a folder. We check the roof after the first rainy season so small things stay small.
Repairs and Maintenance
Most calls start with a leak over one room. We trace it to the source — a split lap, a failed pipe flashing, a drain that never cleared — repair it and photograph what we found. Two things keep a flat roof going: clear the drains before the rains, and have the flashings looked at once a year.
Serving SoMa and the Foothills
We install and repair torch down throughout SoMa, Tujunga, Shadow Hills, Lake View Terrace, La Crescenta, Sylmar and the rest of the northeast city. Flat roof work is dry-weather work, so the calendar tightens once the rain starts — call early.
We’ll measure the roof, check the deck, drains and flashings, and tell you whether torch down is the right system.

WHAT TORCH DOWN ACTUALLY FIXES
Leaks over a tenant space in SoMa almost always trace back to a lap, a flashing or a drain rather than the field of the roof. Marine air keeps a flat roof damp into the morning, so drainage and a clean cap sheet matter more here than anywhere.
Serving SoMa and nearby
We install and repair torch down roofs throughout SoMa and the surrounding San Francisco County communities, including Mission Bay, Hayes Valley and Financial District.
What you can expect from it
Installed to spec, a two-ply torch down roof runs twenty years and up. The manufacturer warranty is written for 10, 20 or 25 years depending on the system, and we register the paperwork in your name.
What the week looks like
- Free inspection with photos of every penetration and drain
- Written scope and price before anything is booked
- Tear-off and deck repair, with bad bays shown to you
- Two plies down, welds probed as the crew goes
- Flashings, drains and edge metal detailed
- Daily clean-up and a final walk with you on the roof
What torch down does better
What the system gives you on a {n} roof:
- The white Polyfresko cap sheet reflects heat rather than storing it
- Repairs weld into the existing sheet, so a fix becomes part of the roof
- It suits cut-up roofs with curbs, pipes and skylights
- It handles ponding better than a single-layer repair ever will
- Two plies mean a second line of defence over the whole roof, not just the patches
What it costs in SoMa
Access matters too: a roof you can only reach by ladder and bucket takes longer than one with a loading zone.
A cut-up roof with ten curbs costs more per square than an open one, because the detailing is the work.
When we recommend something else
If the insulation is wet, no membrane fixes that - it comes off first, whatever it costs.
What you can expect from us
Financing exists if you want it, and nobody pushes it on you.
- Ventilation gets looked at while the roof is open; most SoMa attics run hotter than they should.
- Change orders are discussed before anything is done, not billed afterwards.
- Drip edge and starter course get installed properly - that is half the wind resistance.
- Nothing is left on the lawn overnight, and the dumpster goes when the job ends.
Layer by layer
- Roof deck, repaired where it is soft
- Insulation or cover board, depending on what the building needs
- Modified bitumen base sheet, torched and rolled so the whole sheet bonds
- White Polyfresko cap sheet, seams welded and probed
- Edge metal, curb and pipe flashings detailed last
Talk to a SoMa flat roof crew
The estimate is free. Call (818) 275-0921 and we will measure your SoMa roof, check the deck, laps and drains, and tell you plainly whether coating is the right call.
Conditions we plan for in SoMa
If you own property in SoMa, the local conditions decide what your roof needs: fog drip keeps the north side wet long enough to grow moss. Our shop sits about 337 miles northwest of SoMa, so a crew is on site the same morning.
Crews rotate through Mission Bay, Hayes Valley and Financial District, so the drive is routine.
- Access gets planned first - driveway, staging, dumpster placement - so the street stays usable.
- Permits and inspections run through the local building department, and we pull them rather than leaving it to you.
- We protect landscaping and the pool before a single bundle comes off the truck.
- Where an HOA sets colour or material rules, we match the approved list before the job is quoted.
- Satellite dishes and A/C line sets are re-flashed, not just set back down.
We would rather be on your roof in September than during the first atmospheric river. Ask for the inspection, keep the report, and decide in your own time.
What this costs in SoMa, honestly
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.
We do not use subcontract crews we have never met. The people on your SoMa roof are the people we train, and they carry our workers' compensation.
Questions SoMa owners ask us
The questions we hear most in SoMa are about price, timing and whether a repair will hold. We answer all three before you commit, and we put the answers in writing.

CLEAR ANSWERS. LOCAL EXPERTISE.
SOMA, CA TORCH DOWN ROOFING
Do you give free estimates in SoMa?
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.
Is torch down right for a flat roof in SoMa?
For most flat and low-slope roofs in SoMa, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
What happens to the old roof and the mess?
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.
What is the 2-ply Polyfresko system?
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.
Is the torch safe around my SoMa building?
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.
How long does the work take?
Most single-family roofs in SoMa 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.
Can you work around solar panels?
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.
How long does a torch down roof last?
Installed to spec, twenty years and up, with a manufacturer warranty of 10, 20 or 25 years depending on the system.
