SAN MARINO, CA
Torch Down Roofing
Two Plies, Welded Seams, No Guesswork.
Torch down roofing in San Marino 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 San Marino, Tujunga, Shadow Hills, Lake View Terrace and the northeast San Fernando Valley.
Why Flat Roofs in San Marino Fail
San Marino 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 San Marino
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 San Marino and the Foothills
We install and repair torch down throughout San Marino, 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.

WHAT TORCH DOWN ACTUALLY FIXES
Leaks over a tenant space in San Marino almost always trace back to a lap, a flashing or a drain rather than the field of the roof. Inland heat and seasonal wind work every lap, so the welds and the flashings are where the money belongs.
Where the money goes
Price follows square footage, how many layers come off, how much decking needs replacing and how many penetrations the roof carries.
We price deck repair per sheet so there is no surprise number halfway through the tear-off.
Before, during and after
The site is cleaned daily, and the last magnet pass happens before the crew leaves.
- Most homes take two to four days once material lands.
- We do not ask for large deposits before material is delivered.
- The written warranty names what is covered and for how long, with no asterisk games.
- Drip edge and starter course get installed properly - that is half the wind resistance.
Local conditions in San Marino
We quote San Marino roofs off what the roof is actually doing, and dust, heat and wind arrive together and find any weak detail. 9 miles northeast means a free inspection costs you nothing but an hour.
We know San Gabriel, Alhambra and South Pasadena as well as we know San Marino.
- We photograph every penetration before and after, so the file shows the work.
- Skylights are re-flashed as part of the job rather than quoted as an extra later.
- 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.
- Magnet sweeps run morning and evening, which matters on a street with kids and bare feet.
Summer is for planned work; winter is for emergencies nobody planned. Nothing is booked until you have photos, a scope and a written price.
Serving San Marino and nearby
We install and repair torch down roofs throughout San Marino and the surrounding Los Angeles County communities, including San Gabriel, Alhambra and South Pasadena.
What torch down does better
Why it outlasts patch-on-patch asphalt:
- Manufacturer warranties run 10, 20 or 25 years depending on the system
- The white Polyfresko cap sheet reflects heat rather than storing it
- Heat-welded seams fuse the plies instead of relying on adhesive
- It suits cut-up roofs with curbs, pipes and skylights
- Two plies mean a second line of defence over the whole roof, not just the patches
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
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.
When we recommend something else
If the insulation is wet, no membrane fixes that - it comes off first, whatever it costs.
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

Get a number in writing
The estimate is free. Call (818) 275-0921 and we will measure your San Marino roof, check the deck, laps and drains, and tell you plainly whether coating is the right call.
What goes wrong when it is done cheap
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.
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.
After the job in San Marino
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.

QUESTIONS

CLEAR ANSWERS. LOCAL EXPERTISE.
SAN MARINO, CA TORCH DOWN ROOFING
Is the torch safe around my San Marino 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 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.
Do you pull permits in San Marino?
We do. Permits and inspections go through the local building department and we handle the paperwork rather than leaving it to you.
Is torch down right for a flat roof in San Marino?
For most flat and low-slope roofs in San Marino, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
Are you licensed and insured?
Yes, licensed, bonded and insured, with workers' compensation on every crew. Certificates are available before work starts.
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.
How long does the work take?
Most single-family roofs in San Marino 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.
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.
