BEFORE & AFTER
WEST PORTAL, CA
Torch Down Roofing
Two Plies, Welded Seams, No Guesswork.
Torch down roofing in West Portal 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 West Portal, Tujunga, Shadow Hills, Lake View Terrace and the northeast city.
Why Flat Roofs in West Portal Fail
West Portal 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 West Portal
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 West Portal and the Foothills
We install and repair torch down throughout West Portal, 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 WEST PORTAL, CA
THE COMPLETE GUIDE TO
TORCH DOWN ROOFING IN WEST PORTAL
Flat roofs in West Portal fail at the laps and the details, which is why we install torch down in two plies with every seam heat-welded. Marine air keeps a flat roof damp into the morning, so drainage and a clean cap sheet matter more here than anywhere.
Pricing a West Portal flat roof
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.
Straight talk
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 we see on West Portal roofs
The short version for West Portal: onshore wind drives rain sideways into the flashings. At about 337 miles northwest, West Portal is an easy run for us, inspection or emergency.
You will see our trucks in Forest Hill, Parkside and Saint Francis Wood on the same run.
- Tile is sorted and reused where it is sound, which keeps the roof looking original.
- Solar panels get detached and reset on a schedule that matches the roofing crew.
- Dry-in happens the same day the old roof comes off; nothing sits open overnight.
- We protect landscaping and the pool before a single bundle comes off the truck.
- Skylights are flashed new rather than reused, because that is where the next leak starts.
Summer is for planned work; winter is for emergencies nobody planned. Expect photos, a measured scope and a number you can compare against anyone else.
What this costs in West Portal, 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.
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.
What goes wrong when it is done cheap
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 West Portal tightens fast, and emergency work costs more than planned work.
FREQUENTLY ASKED
QUESTIONS
Find answers to common questions about torch down roofing in West Portal.
CLEAR ANSWERS. LOCAL EXPERTISE.
WEST PORTAL, CA TORCH DOWN ROOFING
Is the torch safe around my West Portal 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 West Portal 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.
Do you pull permits in West Portal?
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 West Portal?
For most flat and low-slope roofs in West Portal, 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.
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.
How much does a new roof cost in West Portal?
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 West Portal property, measure it and put a detailed number in writing before anything is booked.
