Silicone is popular—but is it safe?
Silicone roof coatings are widely used for their UV reflectivity and hydrophobic nature. They’re often considered a budget-friendly alternative to full roof tear-offs, offering quicker installation and less disruption—especially when applied over existing surfaces.
But popularity doesn’t always equal performance.

The “Zipper Effect”: A Major Red Flag
One of the biggest concerns with silicone coatings is what’s known as the “zipper effect.” If a silicone coating is torn—even slightly—due to foot traffic, hail, a dropped tool, or structural movement, that tear can rapidly spread across the surface like a zipper opening. What starts as a small rip can lead to a complete failure of the roof coating.

Safety Risks: Slippery When Wet
Silicone also poses a serious safety risk. When wet, it becomes extremely slippery, making it hazardous for workers during application or routine maintenance.
Triton Inc. partnered with Iowa State University to study the slip resistance of common roof coatings. The findings were clear: Liquid-applied coatings like TritoFlex® and TritoCryl® significantly outperformed silicone in slip resistance tests.

Safer, Smarter Alternatives
At Triton, we don’t sell silicone. Instead, we advocate for stronger, safer, and sensible roofing systems.
TritoFlex®: Our flagship liquid rubber membrane is FM-Approved and designed as a high-performance, no-tear-off roofing solution.
NEOCOAT™: A professional-grade hybrid coating with 92% solar reflectivity. It’s non-toxic, versatile, and can be used over Modified Bitumen, BUR, TPO, PVC, KEE, EPDM, concrete, foam, and metal. It also works as a topcoat for TritoFlex.
Slip-Resistant PVC and TPO: Triton also offers PVC and TPO membranes that are Class A Fire Rated and engineered for safety and durability.
Final Takeaway: Think Before You Silicone
Silicone coatings can offer short-term appeal: fast installs, high reflectivity, and ponding water resistance. But the risks—tearing, slipperiness, and potential system failure—shouldn’t be overlooked.
So the real question isn’t whether silicone is popular. It’s whether it’s safe and dependable enough for your roof.
At Triton, we believe there’s a better way—and we’re here to help you find it.
