Silicone Restoration Membrane: Installation and Performance

The silicone restoration membrane (SRM) transforms aging commercial roofs into freshly warranted systems at a fraction of replacement cost. Here's how it works.

What Is an SRM?

A silicone restoration membrane is a high-solids silicone coating applied at 20–30 mils over an existing commercial roofing membrane (TPO, EPDM, metal, or modified bitumen). It creates a continuous seamless film over the entire existing surface, sealing all seams and issuing a new manufacturer warranty.

Installation Process

Core sampling to verify eligibility → wet insulation removal and replacement → power washing → seam and flashing repairs with reinforced fabric tape → primer application (where required) → two-coat silicone application at required mil thickness → granule broadcast at foot traffic areas → third-party inspection → manufacturer warranty issuance.

Performance Characteristics

Solar reflectance: 85%+ (exceeds most energy code requirements). Thermal emittance: 90%+. Ponding water resistance: approved for standing water applications. UV stability: doesn't chalk, yellow, or lose flexibility over the warranty period. Flexibility: maintains performance from -80°F to 300°F+.

Warranty Options

10, 15, or 20-year manufacturer warranties based on coating thickness. Renewable at warranty end with recoat. Compared to full replacement warranties that require full replacement at expiration — SRM's renewable warranty is a significant long-term advantage.
