CERRITOS, CA
Torch Down Roofing
Two Plies, Welded Seams, No Guesswork.
Torch down roofing in Cerritos 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 Cerritos, Tujunga, Shadow Hills, Lake View Terrace and the northeast San Fernando Valley.
Why Flat Roofs in Cerritos Fail
Cerritos 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 Cerritos
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 Cerritos and the Foothills
We install and repair torch down throughout Cerritos, 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 CERRITOS, CA
THE COMPLETE GUIDE TO
TORCH DOWN ROOFING IN CERRITOS
Most Cerritos buildings with a flat section end up on modified bitumen, and the install decides whether it lasts five years or twenty. Inland heat and seasonal wind work every lap, so the welds and the flashings are where the money belongs.
Why we specify two plies in Cerritos
Why it outlasts patch-on-patch asphalt:
- The white Polyfresko cap sheet reflects heat rather than storing it
- Manufacturer warranties run 10, 20 or 25 years depending on the system
- Two plies mean a second line of defence over the whole roof, not just the patches
- It handles ponding better than a single-layer repair ever will
- It suits cut-up roofs with curbs, pipes and skylights
Pricing a Cerritos flat roof
Price follows square footage, how many layers come off, how much decking needs replacing and how many penetrations the roof carries.
A cut-up roof with ten curbs costs more per square than an open one, because the detailing is the work.
Serving Cerritos and nearby
We install and repair torch down roofs throughout Cerritos and the surrounding Los Angeles County communities, including Artesia, Hawaiian Gardens and Norwalk.
The 2-ply build-up
- 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
When torch down is the wrong call
If the roof is sound and simply weathered, a silicone coating is cheaper than a tear-off and we will tell you so.
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
Local notes for Cerritos
The short version for Cerritos: dust, heat and wind arrive together and find any weak detail. From the shop it is a 17-mile run southeast to Cerritos, so emergencies get a same-day answer.
The roofs in Artesia, Hawaiian Gardens and Norwalk are built much the same way, and they fail the same way.
- Gutters are pulled and refitted properly instead of being crushed by a ladder.
- 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.
- Where an HOA sets colour or material rules, we match the approved list before the job is quoted.
- Solar panels get detached and reset on a schedule that matches the roofing crew.
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.
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.
Get a number in writing
The estimate is free. Call (818) 275-0921 and we will measure your Cerritos roof, check the deck, laps and drains, and tell you plainly whether coating is the right call.
What you can expect from us
An inspection here means walking the roof, not pointing a camera at it from the driveway.
- You get a text when the crew is coming and a walk-through when they are done.
- Ridge venting goes in where the roof line allows it, with proper intake at the eaves.
- Soft decking gets replaced, not covered - we quote a sheet count and show you the bad bays.
- Most homes take two to four days once material lands.
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 Cerritos tightens fast, and emergency work costs more than planned work.
The questions we hear most in Cerritos are about price, timing and whether a repair will hold. We answer all three before you commit, and we put the answers in writing.
Timing the work in Cerritos
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.
CERRITOS, CA TORCH DOWN ROOFING
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 Cerritos?
For most flat and low-slope roofs in Cerritos, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
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 give free estimates in Cerritos?
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 Cerritos 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 much does a new roof cost in Cerritos?
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 Cerritos property, measure it and put a detailed number in writing before anything is booked.
Do you pull permits in Cerritos?
We do. Permits and inspections go through the local building department and we handle the paperwork rather than leaving it to you.
