CHINATOWN, CA
Torch Down Roofing
Two Plies, Welded Seams, No Guesswork.
Torch down roofing in Chinatown 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 Chinatown, Tujunga, Shadow Hills, Lake View Terrace and the northeast city.
Why Flat Roofs in Chinatown Fail
Chinatown 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 Chinatown
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 Chinatown and the Foothills
We install and repair torch down throughout Chinatown, 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.
TORCH DOWN ROOFING CHINATOWN, CA
FLAT ROOFS IN CHINATOWN
WHAT TORCH DOWN ACTUALLY FIXES
If the flat roof on your Chinatown property is patched, ponding or splitting at the laps, torch down is usually the answer. Marine air keeps a flat roof damp into the morning, so drainage and a clean cap sheet matter more here than anywhere.
Lifespan and warranty
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 it costs in Chinatown
We price deck repair per sheet so there is no surprise number halfway through the tear-off.
Price follows square footage, how many layers come off, how much decking needs replacing and how many penetrations the roof carries.
Our process in Chinatown
- 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
When torch down is the wrong call
Where open flame is not appropriate, on a poor wood deck or a tight occupied building, we quote a cold-applied or coating system and say why.
What torch down does better
Why it outlasts patch-on-patch asphalt:
- Manufacturer warranties run 10, 20 or 25 years depending on the system
- It handles ponding better than a single-layer repair ever will
- Repairs weld into the existing sheet, so a fix becomes part of the roof
- Two plies mean a second line of defence over the whole roof, not just the patches
- The white Polyfresko cap sheet reflects heat rather than storing it
Serving Chinatown and nearby
We install and repair torch down roofs throughout Chinatown and the surrounding San Francisco County communities, including North Beach, Nob Hill and Financial District.
What the work looks like in Chinatown
Change orders are written and signed, never verbal.
- Ice-and-water goes in at the valleys and penetrations even though it rarely freezes here.
- Workmanship coverage is ours to honour, and we are still here to honour it.
- You get a start date and a finish date in writing, and we hold them.
- Intake and exhaust are balanced on the same visit - a sealed attic cooks a new roof early.
What the street looks like in Chinatown
Most of what we fix in Chinatown traces back to one thing: whatever fails first on these roofs fails at the edges. From the yard it is roughly 338 miles northwest to Chinatown - no travel surcharge, no week-long wait.
We are in North Beach, Nob Hill and Financial District constantly, and the housing stock is much the same.
- Skylights are re-flashed as part of the job rather than quoted as an extra later.
- Material is delivered the morning of the job, not left on the driveway for a week.
- Tear-off debris leaves the same day; nobody is left with a pile over the weekend.
- Skylights are flashed new rather than reused, because that is where the next leak starts.
- Chimney and wall flashings are replaced, not painted over with sealant.
A roof opened in winter costs more and risks more, so we plan around the forecast. We will tell you if the roof has five years left, because that is also useful to know.
What goes on your Chinatown roof
- 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

What this costs in Chinatown, honestly
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 Chinatown tightens fast, and emergency work costs more than planned work.
We do not use subcontract crews we have never met. The people on your Chinatown roof are the people we train, and they carry our workers' compensation.
After the job in Chinatown
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.

QUESTIONS

CLEAR ANSWERS. LOCAL EXPERTISE.
CHINATOWN, CA TORCH DOWN ROOFING
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.
Are you licensed and insured?
Yes, licensed, bonded and insured, with workers' compensation on every crew. Certificates are available before work starts.
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.
Is torch down right for a flat roof in Chinatown?
For most flat and low-slope roofs in Chinatown, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
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.
Do you give free estimates in Chinatown?
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 the torch safe around my Chinatown 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.
Do you offer any warranty?
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.
