Torch Down Roofing
Two Plies, Welded Seams, No Guesswork.
Torch down roofing in El Cajon 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 El Cajon, Tujunga, Shadow Hills, Lake View Terrace and the northeast San Fernando Valley.
Why Flat Roofs in El Cajon Fail
El Cajon 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 El Cajon
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 El Cajon and the Foothills
We install and repair torch down throughout El Cajon, 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 EL CAJON, CA
THE COMPLETE GUIDE TO
TORCH DOWN ROOFING IN EL CAJON
Most El Cajon 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.
Serving El Cajon and nearby
We install and repair torch down roofs throughout El Cajon and the surrounding San Diego County communities, including La Mesa, Santee and Lakeside.
Why El Cajon roofs wear the way they do
Ask ten El Cajon owners about their roof and you get the same complaints: sun exposure here is relentless from April through October. 127 miles southeast means a free inspection costs you nothing but an hour.
You will see our trucks in La Mesa, Santee and Lakeside on the same run.
- Where an HOA sets colour or material rules, we match the approved list before the job is quoted.
- We protect landscaping and the pool before a single bundle comes off the truck.
- Dry-in happens the same day the old roof comes off; nothing sits open overnight.
- We photograph every penetration before and after, so the file shows the work.
- Tile is sorted and reused where it is sound, which keeps the roof looking original.
We would rather be on your roof in September than during the first atmospheric river. You get photos, measurements and a plain explanation before any work is booked.
How long it lasts
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.
How we run the job in El Cajon
Rake and eave metal is new on every job; reusing bent metal is false economy.
- The quote lists materials and labour separately so you can see what you are buying.
- The written warranty names what is covered and for how long, with no asterisk games.
- Ridge venting goes in where the roof line allows it, with proper intake at the eaves.
- Underlayment is where corners get cut; we use the system the manufacturer warrants.
What goes on your El Cajon 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
Where the money goes
A cut-up roof with ten curbs costs more per square than an open one, because the detailing is the work.
Price follows square footage, how many layers come off, how much decking needs replacing and how many penetrations the roof carries.
When torch down is the wrong call
If the insulation is wet, no membrane fixes that - it comes off first, whatever it costs.
What torch down does better
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
- 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

Questions El Cajon owners ask us
The questions we hear most in El Cajon 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.
What this costs in El Cajon, honestly
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.

Yes, licensed, bonded and insured, with workers' compensation on every crew. Certificates are available before work starts.
How much does a new roof cost in El Cajon?

Is torch down right for a flat roof in El Cajon?
