MISSION BAY, CA
Torch Down Roofing
Two Plies, Welded Seams, No Guesswork.
Torch down roofing in Mission Bay 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 Mission Bay, Tujunga, Shadow Hills, Lake View Terrace and the northeast city.
Why Flat Roofs in Mission Bay Fail
Mission Bay 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 Mission Bay
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 Mission Bay and the Foothills
We install and repair torch down throughout Mission Bay, 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 MISSION BAY, CA
THE COMPLETE GUIDE TO
TORCH DOWN ROOFING IN MISSION BAY
Flat roofs in Mission Bay 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.
When torch down is the wrong call
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 Mission Bay
Access matters too: a roof you can only reach by ladder and bucket takes longer than one with a loading zone.
Price follows square footage, how many layers come off, how much decking needs replacing and how many penetrations the roof carries.
What the week looks like
- 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
Serving Mission Bay and nearby
We install and repair torch down roofs throughout Mission Bay and the surrounding San Francisco County communities, including Dogpatch, SoMa and Potrero Hill.
The parts people ask about
We do not ask for large deposits before material is delivered.
- Synthetic underlayment goes down over the whole deck, not just the valleys.
- Nothing is left on the lawn overnight, and the dumpster goes when the job ends.
- Edges are fastened to spec because that is where uplift starts.
- Keep the paperwork: it transfers if you sell the house.
What torch down does better
The practical reasons it keeps getting specified here:
- Manufacturer warranties run 10, 20 or 25 years depending on the system
- It suits cut-up roofs with curbs, pipes and skylights
- Heat-welded seams fuse the plies instead of relying on adhesive
- The white Polyfresko cap sheet reflects heat rather than storing it
- Repairs weld into the existing sheet, so a fix becomes part of the roof
What we see on Mission Bay roofs
Ask ten Mission Bay owners about their roof and you get the same complaints: onshore wind drives rain sideways into the flashings. From the shop it is a 336-mile run northwest to Mission Bay, so emergencies get a same-day answer.
You will see our trucks in Dogpatch, SoMa and Potrero Hill on the same run.
- Skylights are re-flashed as part of the job rather than quoted as an extra later.
- Gutters are pulled and refitted where they block a proper drip edge.
- We work around tenants and business hours where the building is occupied.
- 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.
The first big storm books out the whole trade, so earlier is cheaper. The inspection is free, and so is the second opinion if you already have a quote.
Layer by layer
- 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
How long it lasts

What this costs in Mission Bay, honestly
The questions we hear most in Mission Bay are about price, timing and whether a repair will hold. We answer all three before you commit, and we put the answers in writing.
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.
Timing the work in Mission Bay
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.

CLEAR ANSWERS. LOCAL EXPERTISE.
MISSION BAY, CA TORCH DOWN ROOFING
Do you pull permits in Mission Bay?
We do. Permits and inspections go through the local building department and we handle the paperwork rather than leaving it to you.
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.
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.
Is torch down right for a flat roof in Mission Bay?
For most flat and low-slope roofs in Mission Bay, 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.
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.
Is the torch safe around my Mission Bay 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.
Are you licensed and insured?
Yes, licensed, bonded and insured, with workers' compensation on every crew. Certificates are available before work starts.
