Ponding water on your flat roof? Silicone stops it cold.
Waterproof protection for flat and low-slope roofs. Handles ponding water, resists UV, and works for both commercial and residential buildings.
What is silicone coating?
Silicone roof coating creates a seamless, waterproof membrane over your existing roof. It's the go-to solution for flat and low-slope roofs that deal with standing water — a common problem in Florida's heavy rain season. We use PermaSil Plus silicone coating from Nationwide Products, a manufacturer with over 60 years in business. One application protects your roof from UV, rain, and thermal cycling for years.
Why Silicone Is the Gold Standard for Flat Roofs
Not all roof coatings are created equal — and the differences matter enormously when your roof is flat. Flat and low-slope roofs in Florida face a unique challenge: water doesn't naturally shed off them the way it does on a pitched roof. After a typical Florida afternoon thunderstorm, water pools in low spots and can sit there for hours or even days.
Most coatings — acrylic, elastomeric, even some urethanes — will eventually break down when continuously exposed to standing water. The water softens the coating, allows biological growth underneath, and eventually leads to delamination and failure. This is why so many flat roof coatings fail prematurely in Florida.
Silicone is chemically different. Once cured, it's essentially inert — water can sit on it indefinitely without degradation. It doesn't absorb moisture, doesn't soften, and doesn't support biological growth. This makes it the only coating we recommend for flat roofs with any ponding water, which in Florida's flat coastal terrain, means virtually every flat roof.
We use PermaSil Plus from Nationwide Products — a manufacturer with over 60 years in the commercial roofing industry. It's not a consumer-grade product from a home improvement store. It's professional-grade silicone, applied with professional equipment by trained crews who know exactly how to achieve uniform coverage and proper thickness.
The Hidden Costs of Not Coating Your Flat Roof
A flat roof without proper coating is a ticking clock. In Florida, the question isn't whether it will leak — it's when. And the real cost of a flat roof leak goes far beyond the roof itself.
Water intrusion through a flat roof damages insulation first, which degrades your building's energy efficiency. Then it reaches the deck — wood, concrete, or metal — where it causes structural damage that compounds over time. In commercial buildings, water damage to inventory, equipment, and interior finishes can dwarf the cost of the roof repair itself.
A silicone coating stops this cascade before it starts. For a fraction of the cost of replacing the entire roof system, you get a seamless, waterproof barrier that handles everything Florida throws at it — daily UV bombardment, afternoon thunderstorms, hurricane rain, and year-round humidity.
The energy savings alone are substantial. A white silicone coating reflects 80–85% of solar radiation, meaning your building absorbs dramatically less heat. For a commercial building with a large flat roof, this can reduce cooling costs by 15–25% — savings that continue for the full 15–20 year life of the coating.

Why choose silicone coating?
Here's what sets our silicone coating service apart.
Handles ponding water
Unlike other coatings, silicone won't break down when water sits on it. Ideal for flat roofs with drainage issues — a reality for most Florida commercial buildings.
UV and weather resistant
Silicone reflects UV radiation and withstands Florida's temperature swings without cracking or peeling. It's chemically inert once cured.
Seamless membrane
No seams means no weak points. The coating conforms to your roof's exact shape, flashings, and penetrations — eliminating every potential leak path.
Reduces cooling costs
Reflective white coating bounces solar heat, lowering your building's interior temperature by up to 15°F and cutting A/C bills significantly.
How it works
Our simple, transparent process from start to finish.
Free Roof Assessment
We inspect your flat or low-slope roof from edge to edge — checking membrane condition, seam integrity, drainage patterns, and ponding areas. We measure existing membrane thickness and assess whether silicone is the right product for your specific situation.
Surface Prep & Application
Proper preparation is everything. We soft wash the surface to remove dirt, algae, and debris. Any seam separations, blisters, or damaged areas are repaired. Then our crew applies PermaSil Plus silicone coating in multiple passes using calibrated spray equipment, ensuring uniform thickness and complete coverage.
Inspection & Warranty
After the coating has cured, our inspector reviews adhesion, thickness, and coverage across the entire surface. You receive full documentation including photos, thickness measurements, and warranty information for your records and insurance carrier.
Technical Specifications
The details that matter — for homeowners and professionals alike.
Is this right for you?
This service is ideal for:
- Flat or low-slope roofs with ponding water after rain
- Commercial buildings — strip malls, warehouses, offices, restaurants
- Residential flat roof sections — lanais, additions, garages
- Buildings with high cooling costs due to heat absorption
- Aging TPO or modified bitumen roofs that need restoration, not replacement
Why not just replace?
A full flat roof replacement means tearing off the existing membrane, repairing or replacing the deck, installing new insulation, and applying a new membrane system. That process typically costs 2–3x more than a silicone coating, takes weeks instead of days, and generates tons of landfill waste. If your existing roof deck is structurally sound, coating is the smarter investment.
Local to Southwest Florida
Sarasota County has thousands of commercial flat roofs — from the shopping centers along US-41 to the office parks in Lakewood Ranch to the waterfront restaurants on St. Armands Circle. Nearly all of them face the same challenge: ponding water in Florida's flat, rain-heavy climate. Silicone coating is the standard solution for this environment, and our crew has applied it across the entire region.

Common Questions
Got questions? Here are the answers to the most common ones.
Yes. Any flat or low-slope residential roof is a good candidate — lanai roofs, additions, garage flat sections. It's also the gold standard for commercial buildings.
With proper application, a silicone roof coating can last 15–20 years before it needs recoating. It doesn't crack, chalk, or harden over time like other coatings.
In most cases, yes. Silicone can be applied over TPO, EPDM, modified bitumen, metal, and existing silicone coatings. The key requirement is that the existing substrate is in reasonable structural condition.
Silicone is the only roof coating that handles ponding water without degradation. If your flat roof has areas where water sits after rain — which is extremely common in Florida — silicone is the right choice.
Typically 50–70% less than a full tear-off and replacement. For a 3,000 sq ft commercial flat roof, you're looking at significant savings — often $10,000 or more.
