How Does an SRM Roofing Solution Restore a Rubber Roof?

A silicone restoration membrane (SRM) transforms an aging, leaking EPDM rubber roof into a freshly warranted system at a fraction of replacement cost. Here's exactly how it works.

Step 1: Core Sample Assessment

Before any work begins, core samples confirm wet insulation levels. For restoration to proceed, wet insulation must be below 25% of the total area. Wet sections are identified, cut out, and replaced with dry insulation.

Step 2: Surface Preparation

The EPDM surface is power-washed to remove all dirt, chalk, and contaminants. EPDM's smooth surface typically requires primer application to ensure proper chemical bonding with the silicone coating. The primer is applied and allowed to cure per manufacturer specifications.

Step 3: Seam and Flashing Repairs

Failed seams and flashing are addressed before the coating — reinforced fabric tape embedded in compatible sealant strengthens existing seam locations before the coating seals over them.

Step 4: SRM Application

The silicone coating is spray-applied in two coats over the entire EPDM surface. Each coat is allowed to cure before the next is applied. The two coats together achieve the required mil thickness for the chosen warranty tier (typically 20 mils for 10 years, 30+ mils for 20 years).

Step 5: Warranty Issuance

A third-party inspector verifies thickness and coverage. The manufacturer issues a new warranty — the rubber roof is now protected by a continuous silicone membrane with a fresh 10–20-year manufacturer warranty, at $2.50–$4.50/sq ft vs. $7–$12/sq ft for replacement.
