Silicone Roof Coatings for Commercial Roofs in Los Angeles & Orange County
A seamless, bright-white silicone membrane applied right over your existing flat roof. It stops leaks, stands up to ponding water, and reflects SoCal sun — without a tear-off, and usually at a fraction of the cost of replacement.
What Is a Silicone Roof Coating?
A silicone roof coating is a liquid-applied membrane that cures into a seamless, flexible, waterproof layer over an existing commercial roof. Instead of tearing off a worn roof, we clean it, repair and reinforce the weak points, and coat the entire surface — giving the building a new, watertight, reflective roof on top of the old one.
Silicone is the go-to restoration coating for flat and low-slope roofs because it resists UV breakdown and holds up where water ponds after rain, where many other coatings struggle.
Silicone Goes Over Most Commercial Roofs
- Modified bitumen — torch-down and cap sheet roofs
- Built-up roofing (BUR) — gravel and smooth surfaces
- Single-ply — TPO and other membranes, with the right primer
- Metal roofs — see metal roof coatings
- Previously coated roofs — including old silicone

Benefits of Silicone Roof Coating Systems
Handles Ponding Water
Silicone resists breakdown under standing water — a big deal on flat roofs with low spots or slow drains.
One Continuous Membrane
No seams for water to find. The coating flows over laps, flashings, and penetrations into a single watertight layer.
No Tear-Off
Restoring over the existing roof avoids demolition, disposal, and new insulation — usually far less than replacement.
Cool Roof Surface
A bright-white, reflective finish lowers roof surface temperature and can cut the cooling load on the building below.
UV & Weather Stable
Silicone holds up to years of direct sun and daily heat cycling without becoming brittle or chalking away.
Recoatable
When the coating eventually wears, it can be cleaned and recoated with silicone — no tear-off needed then, either.
Fast, Low-Odor Application
Silicone cures with moisture in the air, has low odor, and goes on without heat or torches — easier on tenants.
Business Stays Open
All work happens on the roof surface, so buildings typically stay fully operational throughout the project.
Low Maintenance
Once installed, a silicone roof needs routine inspections and drain clearing — not constant patching.
Is Your Roof a Good Candidate for Silicone?
Coatings restore roofs — they don't rebuild them. Here's how we tell the difference during an inspection.
Restore With Silicone
- Roof deck is structurally sound
- Insulation is mostly dry
- Leaks, cracking, or a worn, weathered surface
- Ponding water or a hot, heat-soaked roof
Repair or Replace First
- Widespread saturated insulation
- Deck damage, soft spots, or sagging
- A roof that's failed across most of its surface
Our Silicone Roof Coating Process
The coating is the last step. What makes a silicone roof last is everything we do before it goes on.
Inspect
Full roof inspection to confirm the roof is a coating candidate and find every weak point.
Power Wash
Dirt, debris, and loose material removed so the silicone bonds to a clean surface.
Repair
Wet or damaged areas repaired, blisters and splits fixed, and drains cleared.
Reinforce
Seams, flashings, penetrations, and drains reinforced — the details where roofs leak.
Coat
Primer where the roof calls for it, then silicone applied across the full surface to the system's specified thickness.
Inspect & Warranty
Final inspection, touch-ups, cleanup, and your warranty paperwork.

We install both. Here's how they compare on the factors that matter most for SoCal commercial roofs.
| Silicone | Acrylic | |
|---|---|---|
| Ponding water | Excellent — resists standing water | Best on roofs that drain well |
| UV & sun exposure | Excellent — very UV stable | Good — UV resistant |
| Stays clean & bright | Can collect dirt over time | Stays cleaner and brighter |
| Application | Moisture-cure, low odor | Water-based, low odor |
| Future recoat | Recoat with silicone | Recoat with acrylic |
| Best fit | Flat roofs, ponding, max durability | Sloped or well-drained roofs, tighter budgets |

Silicone Roof Coating FAQs
Can silicone roof coating be applied over an existing roof?
Yes — that's the main advantage. As long as the roof deck is sound and the insulation is mostly dry, silicone goes right over existing modified bitumen, built-up, single-ply, metal, and previously coated roofs after cleaning, repairs, and reinforcement.
Does silicone roof coating work with ponding water?
Yes. Silicone resists breakdown under standing water better than many other coatings, which is why it's a top choice for flat roofs with low spots or slow drains. We still clear drains and address major drainage issues during prep.
How much does a silicone roof coating cost compared to replacement?
Silicone restoration typically costs far less than a full roof replacement because there's no tear-off, disposal, or new insulation. Your price depends on roof size, condition, repairs needed, and the warranty term. We provide a free, written estimate after inspecting the roof.
How long does a silicone roof coating last?
Service life depends on the coating thickness applied and the warranty term of the system. When the coating eventually wears, the roof can be cleaned and recoated with silicone rather than torn off.
Is silicone roof coating a cool roof?
Yes. Bright-white silicone is highly reflective, lowering roof surface temperature and the cooling load on the building. Cool roof coatings can also help with California Title 24 cool roof requirements — we'll confirm what applies to your project.
Should I choose silicone or acrylic?
Silicone is the better fit for flat roofs with ponding water and maximum durability. Acrylic works well on sloped or well-drained roofs and stays cleaner over time. See our acrylic roof coatings page or ask us to compare both for your roof.
Can my building stay open during a silicone coating project?
In most cases, yes. All of the work happens on the roof, with no tear-off, and silicone has low odor — so tenants and operations can usually carry on as normal.
Is a silicone roof coating covered by a warranty?
Yes. Silicone systems carry a manufacturer warranty, and our workmanship is backed by our own warranty. The warranty term depends on the system specified for your roof — we'll lay out your options in the estimate.
