BONITA, CA
Torch Down Roofing
Two Plies, Welded Seams, No Guesswork.
Torch down roofing in Bonita 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 Bonita, Tujunga, Shadow Hills, Lake View Terrace and the northeast San Fernando Valley.
Why Flat Roofs in Bonita Fail
Bonita 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 Bonita
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 Bonita and the Foothills
We install and repair torch down throughout Bonita, 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 Bonita 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.
What torch down does better
The practical reasons it keeps getting specified here:
- 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
- The white Polyfresko cap sheet reflects heat rather than storing it
- Heat-welded seams fuse the plies instead of relying on adhesive
- Manufacturer warranties run 10, 20 or 25 years depending on the system
What goes on your Bonita 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
Serving Bonita and nearby
We install and repair torch down roofs throughout Bonita and the surrounding San Diego County communities, including Chula Vista, National City and Spring Valley.
What separates a good job from a cheap one
The site is cleaned daily, and the last magnet pass happens before the crew leaves.
- Drone shots cover the steep sections, and the rest is checked on foot.
- The quote lists materials and labour separately so you can see what you are buying.
- Soft decking gets replaced, not covered - we quote a sheet count and show you the bad bays.
- Synthetic underlayment goes down over the whole deck, not just the valleys.
Straight talk
If the insulation is wet, no membrane fixes that - it comes off first, whatever it costs.
Why Bonita roofs wear the way they do
The job list in Bonita repeats itself for a reason - hot dry summers and sharp day-to-night swings work the materials loose. 133 miles southeast means a free inspection costs you nothing but an hour.
Neighbouring work in Chula Vista, National City and Spring Valley means materials are already staged nearby.
- Solar gets detached and reset by a licensed crew, not improvised around.
- Satellite dishes and A/C line sets are re-flashed, not just set back down.
- We work around tenants and business hours where the building is occupied.
- Dry-in happens the same day the old roof comes off; nothing sits open overnight.
- Magnet sweeps run morning and evening, which matters on a street with kids and bare feet.
The crews fill up fast when the first storm is on the ten-day forecast. The inspection is free, and so is the second opinion if you already have a quote.
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.
Pricing a Bonita 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.
Our process in Bonita
- 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 this costs in Bonita, honestly
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.
We do not use subcontract crews we have never met. The people on your Bonita roof are the people we train, and they carry our workers' compensation.
After the job in Bonita
The questions we hear most in Bonita are about price, timing and whether a repair will hold. We answer all three before you commit, and we put the answers in writing.

QUESTIONS
Find answers to common questions about torch down roofing in Bonita.
CLEAR ANSWERS. LOCAL EXPERTISE.
BONITA, CA TORCH DOWN ROOFING
How much does a new roof cost in Bonita?
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 Bonita property, measure it and put a detailed number in writing before anything is booked.
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.
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.
Are you licensed and insured?
Yes, licensed, bonded and insured, with workers' compensation on every crew. Certificates are available before work starts.
Is the torch safe around my Bonita 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.
Is torch down right for a flat roof in Bonita?
For most flat and low-slope roofs in Bonita, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
Can you work around solar panels?
Yes. Panels are detached and reset on a schedule that matches the roofing crew, and the penetrations are re-flashed properly when they go back.
