Silicone roof coatings are one of the most durable and weather-resistant options for commercial and residential buildings. At Top Shield Roofing Systems, we recommend silicone coatings to clients looking for premium protection—especially in areas with heavy rain or intense sunlight.
What Are Silicone Roof Coatings?
Silicone coatings are made from silicone polymers and solvents, forming a thick, flexible membrane over an existing roof. They’re designed to withstand ponding water, UV rays, and harsh weather conditions.
Key Benefits
Ponding Water Resistance
Unlike other coatings, silicone remains unaffected by standing water.
UV Stability
High resistance to sun exposure without chalking or cracking.
Durability
Extremely tough and long-lasting—can last up to 20 years with proper application.
Moisture Cure
Silicone cures faster than many coatings, even in humid conditions.
Low Maintenance
Repels dirt and resists mildew, keeping roofs cleaner longer.
Energy Efficient
Reflective white surface helps reduce indoor temperatures and AC costs.
Best Use Cases
Flat or low-slope roofs
Commercial buildings
Areas prone to water pooling
Older roofs needing restoration
Potential Drawbacks
Slippery Surface
Can be slick when wet, especially on low-slope roofs.
Difficult Recoating
New coatings don’t adhere well to old silicone—special prep is required.
Higher Initial Cost
More expensive than acrylic or polyurethane options.
