ARCADIA, CA
Torch Down Roofing
Two Plies, Welded Seams, No Guesswork.
Torch down roofing in Arcadia 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 Arcadia, Tujunga, Shadow Hills, Lake View Terrace and the northeast San Fernando Valley.
Why Flat Roofs in Arcadia Fail
Arcadia 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 Arcadia
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 Arcadia and the Foothills
We install and repair torch down throughout Arcadia, Tujunga, Shadow Hills, Lake View Terrace, La Crescenta, Sylmar and the rest of the northeast San Fernando Valley. 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 ARCADIA, CA
THE COMPLETE GUIDE TO
TORCH DOWN ROOFING IN ARCADIA
A torch down roof is two plies of modified bitumen, welded as they go down, and on a flat Arcadia roof that is what keeps water out. Up against the hills the wind gets at the edges first, so the perimeter metal and the first course decide how long the roof holds.
When torch down is the wrong call
If the insulation is wet, no membrane fixes that - it comes off first, whatever it costs.
What torch down does better
Why it outlasts patch-on-patch asphalt:
- 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
- It suits cut-up roofs with curbs, pipes and skylights
- Manufacturer warranties run 10, 20 or 25 years depending on the system
- Heat-welded seams fuse the plies instead of relying on adhesive
Arcadia in detail
Roof life in Arcadia is decided by exposure more than brand, and steep lots and open exposure age the windward side years ahead of the rest. We are roughly 13 miles northeast of Arcadia, close enough for a same-day look at a leak.
We know Sierra Madre, Monrovia and Temple City as well as we know Arcadia.
- Satellite dishes and A/C line sets are re-flashed, not just set back down.
- Permits and inspections run through the local building department, and we pull them rather than leaving it to you.
- Access gets planned first - driveway, staging, dumpster placement - so the street stays usable.
- 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.
A roof opened in winter costs more and risks more, so we plan around the forecast. No pressure, no same-day-only discount, no hard close.
How long it lasts
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.
How the job runs
- 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 the work looks like in Arcadia
Underlayment is where corners get cut; we use the system the manufacturer warrants.
- Ridge venting goes in where the roof line allows it, with proper intake at the eaves.
- Neighbours get a heads-up about the dumpster before it lands.
- Deck repairs are priced per sheet so there is no surprise number halfway through.
- Edges are fastened to spec because that is where uplift starts.
Serving Arcadia and nearby
We install and repair torch down roofs throughout Arcadia and the surrounding Los Angeles County communities, including Sierra Madre, Monrovia and Temple City.
Pricing a Arcadia flat roof
A cut-up roof with ten curbs costs more per square than an open one, because the detailing is the work.
We price deck repair per sheet so there is no surprise number halfway through the tear-off.
What goes on your Arcadia 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

Questions Arcadia owners ask us
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.
The questions we hear most in Arcadia are about price, timing and whether a repair will hold. We answer all three before you commit, and we put the answers in writing.
What goes wrong when it is done cheap
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.

CLEAR ANSWERS. LOCAL EXPERTISE.
ARCADIA, CA TORCH DOWN ROOFING
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.
Do you pull permits in Arcadia?
We do. Permits and inspections go through the local building department and we handle the paperwork rather than leaving it to you.
Is the torch safe around my Arcadia 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.
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.

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 Arcadia?
For most flat and low-slope roofs in Arcadia, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.

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.
