Commercial Silicone Roof Coating
Replacing a commercial roof is not always the first or best solution. If an existing roof is structurally sound but showing signs of age, a silicone roof coating may restore waterproofing, extend the roof’s service life, and postpone a full replacement.
Silicone roof coatings create a seamless protective membrane over many existing commercial roofing systems. The coating helps resist water intrusion, protects the roof from ultraviolet (UV) exposure, and reduces ongoing maintenance when applied to a roof that qualifies for restoration.
If you’re evaluating your options, begin with a professional roof inspection. We’ll determine whether your roof is a good candidate for a silicone coating system.
What Is Silicone Roof Coating?
A silicone roof coating is a liquid-applied roofing material that cures into a seamless, waterproof membrane across an existing commercial roof. Unlike a complete roof replacement, silicone restoration preserves much of the existing roof assembly when the underlying roof remains in serviceable condition.
Restoration vs. Replacement: What’s the Difference?
A full Commercial Roof Replacement involves tearing down the existing assembly to the deck, creating heavy construction noise, parking lot blockades, and significant landfill waste. While a silicone roof restoration leaves your existing roof completely intact. Our team cleans the surface, repairs isolated flashings, and applies the liquid silicone over the entire deck, restoring total waterproofing without interrupting your daily business operations.
Can a silicone roof coating be applied over my existing roof?
In most cases, yes. Silicone adheres exceptionally well to almost every major commercial roofing substrate across Georgia, Alabama, and Tennessee:
- Metal Roofs: Seals leaking lap seams, rusted fasteners, and expansion joints.
- Single-Ply Membranes (TPO, PVC, EPDM): Restores aged, chalking, or shrinking membranes.
- Modified Bitumen & Built-Up Roofing (BUR): Fills surface cracks and locks down loose aggregate.
- Existing Coated Roofs: Re-coats older acrylic or silicone systems that are reaching the end of their warranty.
How do I know if my roof qualifies for restoration?
A roof is an ideal candidate for silicone coating if the underlying structure is dry and stable. During our initial evaluation, we look for three key qualifiers:
- Substrate Dryness: Less than 15% to 20% of the underlying insulation contains trapped moisture.
- Structural Stability: The roof deck, parapets, and joists are structurally sound with no widespread sagging.
- Seam Integrity: Most existing seams and flashings are intact or easily repairable.
When it doesn’t qualify: If your roof suffers from widespread saturated insulation, decking rot, or severe storm collapse, a coating will only trap water underneath. In those cases, a full replacement is required.
How does silicone handle standing (ponding) water?
Unlike water-based acrylic coatings that break down and re-emulsify when submerged, silicone is chemically hydrophobic. It resists permanent ponding water, making it the premier choice for flat commercial roofs with poor slope or slow-draining areas.
Cost Comparison: Restoration vs. Tear-Off
In 2025 and 2026, the average cost to restore a commercial roof with a silicone coating can range from $2.50 to $5.00 per square foot, compared to triple that per square foot for a full tear-off and replacement. Final pricing depends on roof size, required pressure-washing prep, seam priming, and whether you select a 10-year, 15-year, or 20-year manufacturer warranty material thickness.
