Unmatched UV Stability
Silicone roof coatings are 100% UV stable, meaning they don’t degrade, chalk, or become brittle under prolonged exposure to sunlight.
Strong reds and blues are the exception to this rule, since these will always fade, regardless of the technology used. However, they won’t become brittle.
Why it matters:
Metal roofs get intense UV exposure. Alternative metal roof coatings like acrylics tend to chalk quickly or lose elasticity over time—silicone doesn’t.
Waterproof & Impermeable
Silicone roof coatings are hydrophobic. They repel water and remain flexible even when submerged, are exposed to very low or high temperatures.
Why it matters:
Ponding water isn’t typical on pitched metal roofs, but it can and does occur at the vulnerable areas, for example, where fixings have been over-tightened.
Extreme Flexibility
Silicone roof coatings maintain elasticity in a wide temperature range (often -50°C to +150°C), accommodating metal roof movement (expansion/contraction) without cracking.
Why it matters:
Metal roofs expand and contract constantly with thermal movement. Brittle or semi-rigid coatings will eventually fail at laps, joints, and fixings. Silicone handles dynamic movement exceptionally well.
Proven Reliability
Silicone roof coatings can last 25+ years without significant degradation, even in harsh industrial or coastal environments. Always look for BBA Approval, since not all silicone roof coatings are created equally.
Why it matters:
Specifiers and industrial building owners want proven, long-term protection and fewer lifecycle interventions and silicone is one of the few materials that can deliver on that promise.
| Advantage | Silicone Coatings | Hybrids / Others |
|---|---|---|
| UV Resistance | Excellent | Moderate |
| Water Resistance | Total barrier | Water-resistant only |
| Flexibility | Very high | Medium |
| Fire & BBA Certification | Often available | Rarely available |
| Long-Term Performance | 20+ years proven | Not proven |
| Movement Accommodation | Excellent | Variable |
Summary
Silicone roof coatings are chemically engineered for longevity, movement, and environmental resilience.
For pitched metal roofs, where durability, movement, and weather resistance are mission-critical, silicone-based systems offer the most reliable, certifiable, and specification-friendly solution available.
Our Silicone Products
Did you know that Liquasil’s silicone roof coatings and liquid gutter liner are made to our own exacting recipes and are built from the ground-up at polymer level?
Some roof coating manufacturers simply dilute silicone sealant with huge amounts of solvent and then call them coatings.
The difference is remarkable, which is why most installers rave about the quality of Liquasil systems.

SPECIFY OR BUY LIQUASIL'S SILICONE ROOF COATINGS
Specifying Liquasil products is easy.
Professional specifiers are invited to call us to arrange a free site visit. We will determine whether the roof is suitable to be coated, because some aren’t.
Additionally we will provide you with a site-specific specification taking into account the condition of the existing substrate.
For main contractors and potential installers, we can provide instant, over-the-phone quotations on any of our systems.
Our product training is free of charge.
We know price is important and we guarantee that you will not find another BBA Approved silicone roof coating at a better price – and remember, our metal roof coating treats cut edge corrosion as standard.
