SIMI VALLEY, CA
Torch Down Roofing
Two Plies, Welded Seams, No Guesswork.
Torch down roofing in Simi Valley 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 Simi Valley, Tujunga, Shadow Hills, Lake View Terrace and the northeast San Fernando Valley.
Why Flat Roofs in Simi Valley Fail
Simi Valley 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 Simi Valley
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 Simi Valley and the Foothills
We install and repair torch down throughout Simi Valley, 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 SIMI VALLEY, CA
THE COMPLETE GUIDE TO
TORCH DOWN ROOFING IN SIMI VALLEY
Flat roofs in Simi Valley fail at the laps and the details, which is why we install torch down in two plies with every seam heat-welded. 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.
Our process in Simi Valley
- 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
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.
When we recommend something else
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 it costs in Simi Valley
Access matters too: a roof you can only reach by ladder and bucket takes longer than one with a loading zone.
We price deck repair per sheet so there is no surprise number halfway through the tear-off.
Why torch down for a Simi Valley flat roof
Why it outlasts patch-on-patch asphalt:
- Manufacturer warranties run 10, 20 or 25 years depending on the system
- It handles ponding better than a single-layer repair ever will
- Heat-welded seams fuse the plies instead of relying on adhesive
- Repairs weld into the existing sheet, so a fix becomes part of the roof
- Two plies mean a second line of defence over the whole roof, not just the patches
The things that actually matter
Synthetic underlayment goes down over the whole deck, not just the valleys.
- Payment is tied to progress, not demanded up front.
- You get the manufacturer warranty on the materials and ours on the workmanship, both in writing.
- Edges are fastened to spec because that is where uplift starts.
- We check the attic as well as the roof; half of what we find shows from underneath.
Simi Valley in detail
Ask any crew that works Ventura County and they will tell you the same thing - sun on the exposed slopes dries out the cheap underlayments early. At about 34 miles northwest, Simi Valley is an easy run for us, inspection or emergency.
Moorpark and Thousand Oaks are on the same route, which keeps follow-ups easy.
- Skylights are re-flashed as part of the job rather than quoted as an extra later.
- Permits and inspections run through the local building department, and we pull them rather than leaving it to you.
- Chimney and wall flashings are replaced, not painted over with sealant.
- Access gets planned first - driveway, staging, dumpster placement - so the street stays usable.
- Dry-in happens the same day the old roof comes off; nothing sits open overnight.
Scheduling before the rains means the whole job happens on dry decking. If a repair solves it, we quote the repair instead of selling a replacement.
What goes on your Simi Valley 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

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

CLEAR ANSWERS. LOCAL EXPERTISE.
SIMI VALLEY, CA TORCH DOWN ROOFING
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.
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.
Is torch down right for a flat roof in Simi Valley?
For most flat and low-slope roofs in Simi Valley, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
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 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.
Is the torch safe around my Simi Valley 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.
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.
Do you pull permits in Simi Valley?
We do. Permits and inspections go through the local building department and we handle the paperwork rather than leaving it to you.
