Torch Down Roofing
Two Plies, Welded Seams, No Guesswork.
Torch down roofing in San Dimas 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.
Beverly Hills Roofing & Commercial Roof Repair installs and repairs torch down on houses with flat sections, apartment buildings, HOA property, offices and light industrial across San Dimas, Tujunga, Shadow Hills, Lake View Terrace and the northeast San Fernando Valley.
Why Flat Roofs in San Dimas Fail
San Dimas 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 San Dimas
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 San Dimas and the Foothills
We install and repair torch down throughout San Dimas, 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 SAN DIMAS, CA
FLAT ROOFS IN SAN DIMAS
WHAT TORCH DOWN ACTUALLY FIXES
If the flat roof on your San Dimas property is patched, ponding or splitting at the laps, torch down is usually the answer. 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.
Why torch down for a San Dimas flat roof
What the system gives you on a {n} roof:
- Heat-welded seams fuse the plies instead of relying on adhesive
- It suits cut-up roofs with curbs, pipes and skylights
- Manufacturer warranties run 10, 20 or 25 years depending on the system
- Repairs weld into the existing sheet, so a fix becomes part of the roof
- The white Polyfresko cap sheet reflects heat rather than storing it
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.
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
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
What it costs in San Dimas
A cut-up roof with ten curbs costs more per square than an open one, because the detailing is the work.
We price deck repair per sheet so there is no surprise number halfway through the tear-off.
What separates a good job from a cheap one
We do not ask for large deposits before material is delivered.
- We check the attic as well as the roof; half of what we find shows from underneath.
- Synthetic underlayment goes down over the whole deck, not just the valleys.
- You get a text when the crew is coming and a walk-through when they are done.
- Weather delays are called early rather than left to surprise you.
Serving San Dimas and nearby
We install and repair torch down roofs throughout San Dimas and the surrounding Los Angeles County communities, including La Verne, Glendora and Pomona.
When we recommend something else
If the insulation is wet, no membrane fixes that - it comes off first, whatever it costs.
Book a free San Dimas inspection
The estimate is free. Call (424) 258-9253 and we will measure your San Dimas roof, check the deck, laps and drains, and tell you plainly whether coating is the right call.
What changes on a San Dimas roof
Roof life in San Dimas is decided by exposure more than brand, and sun on the exposed slopes dries out the cheap underlayments early. San Dimas is around 25 miles east of the shop, which keeps scheduling simple.
La Verne, Glendora and Pomona are on the same route, which keeps follow-ups easy.
- We work around tenants and business hours where the building is occupied.
- 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.
- Gutters are pulled and refitted where they block a proper drip edge.
- Solar panels get detached and reset on a schedule that matches the roofing crew.
Scheduling before the rains means the whole job happens on dry decking. You get photos, measurements and a plain explanation before any work is booked.
Questions San Dimas owners ask us
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.
Price follows the roof, not a rate card: access, pitch, material, how many layers come off and what the deck looks like underneath. We measure in person, show you photos and put the number in writing before anything is booked.
What goes wrong when it is done cheap
We do not use subcontract crews we have never met. The people on your San Dimas roof are the people we train, and they carry our workers' compensation.

QUESTIONS

CLEAR ANSWERS. LOCAL EXPERTISE.
SAN DIMAS, CA TORCH DOWN ROOFING
When is the best time to have roof work done in San Dimas?
For San Dimas, after the first Santa Ana winds, because that is when ridge and edge details move. Emergency work happens whenever it has to, but planned work is cheaper and safer on a dry roof.
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 San Dimas?
For most flat and low-slope roofs in San Dimas, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
Are your crews familiar with San Dimas homes?
Yes. The housing stock around San Dimas repeats itself, so we know what is under most of these roofs before we lift anything, and what tends to fail on them.
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.
What goes wrong with roofs specifically in San Dimas?
In San Dimas, wind off the slopes gets under the first courses and the ridge before anywhere else, and debris from mature trees fills the valleys every autumn. That is what we look at first, before anything else on the roof.
Do you serve the streets around San Dimas too?
Yes — La Verne, Glendora and Pomona are all on the same run, so there is no travel surcharge between them.
Do you give free estimates in San Dimas?
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.
