Commercial Silicone Roof Coating
The most cost-effective solution for aging flat roofs. Applied over your existing membrane — no tear-off, no disruption, 15-year warranty.
What Is Commercial Silicone Roof Coating?
Silicone Restoration Membrane (SRM) is a liquid-applied, 100% silicone coating that is sprayed or rolled directly onto your existing flat roof surface. It cures to a seamless, flexible, fully waterproof membrane that bonds directly to your existing roofing material — TPO, EPDM, modified bitumen, built-up roofing, metal, and more.
Unlike tear-off and replacement, silicone coating preserves your existing roof deck, eliminates disposal costs, and can typically be completed in 1–3 days with no business interruption.
Cost Comparison: Coating vs. Replacement
| Option | Cost/Sq Ft | Install Time | Warranty | Disruption |
|---|---|---|---|---|
| Silicone Coating | $3–6 | 1–3 days | 15 years | Minimal |
| TPO Replacement | $8–12 | 3–7 days | 10–20 years | Significant |
| EPDM Replacement | $8–14 | 3–7 days | 10–20 years | Significant |
| Built-Up Replacement | $10–16 | 5–10 days | 10–15 years | Major |

Frequently Asked Questions
How long does silicone roof coating last?
Properly applied silicone coating has a service life of 15–25 years. We provide a written 15-year warranty on all projects. The coating can also be re-coated at the end of its life for an additional service term — potentially making it the last roof replacement you ever need.
Will it work on my roof with existing leaks?
Yes, in most cases. Existing leak points are repaired during surface preparation before the full coating is applied. The seamless silicone membrane then covers and seals the entire surface, eliminating not just the known leaks but all potential future entry points.
What if my roof has significant damage?
We assess the roof deck condition during the initial inspection. If moisture saturation exceeds 25% of the roof area, silicone coating may not be the right solution and we’ll tell you honestly. For roofs with isolated damage, repair and coating is almost always more cost-effective than full replacement.
