Silicone fluid-applied coatings extend the life of existing Fort Worth commercial roofs without full tear-off — with 10, 15, and 20-year warranty options depending on mil thickness and substrate condition.

Silicone roof coating is a fluid-applied roofing system — silicone polymer sprayed or rolled over an existing roof membrane to restore waterproofing, add reflectivity, and extend the asset's service life with a new manufacturer warranty. It is not a patch or a coating in the maintenance sense. When properly specified and applied at the correct mil thickness over a prepared substrate, it is a warranted roofing system that can extend a commercial roof's life by 10-20 years.

The Fort Worth commercial buildings where we most commonly specify silicone coating are TPO and EPDM systems in the 12-20 year age range — past the first maintenance cycle, showing surface oxidation and minor seam wear, but with dry insulation confirmed by moisture cores. These are buildings where a full replacement would cost $8-12 per square foot and a silicone coating system would cost $3-5 per square foot. The recover path makes economic sense, and we close it out with a new manufacturer warranty.

Silicone is also the right specification for roofs where ponding water is a persistent condition. Silicone does not degrade in standing water — it is one of the few coating materials that maintains its waterproofing performance in ponding conditions. For Fort Worth buildings with inadequate slope and chronic ponding where drain improvement is not feasible, silicone coating outperforms acrylic or urethane alternatives.

Silicone Coating Warranty Options — 10, 15, and 20 Years

Silicone coating warranty terms are primarily a function of applied mil thickness. Standard specifications run from 20-25 dry mils for a 10-year warranty to 30-40 dry mils for a 15-year warranty to 40-50+ dry mils for a 20-year warranty. The relationship between mils and warranty is published by the manufacturer (GE Enduris, Conklin, Tremco, and others all offer tiered warranty programs) and is verified by wet-film thickness gauging during application and dry-film core sampling after cure.

We spec the warranty term based on the owner's capital horizon. A building owner who plans to sell the property in 7-8 years does not need a 20-year system — a 10-year system at lower mil thickness costs significantly less and covers the capital horizon. A building owner who plans to hold for 20 years and wants to avoid a capital replacement decision wants the 20-year system. We have this conversation explicitly before the specification is finalized.

Silicone coatings applied at 40+ mils carry full-value warranties from some manufacturers — the manufacturer pays repair and replacement costs for warranted defects for the warranty term with no dollar limit. At lower mil thicknesses, warranties may carry per-square cost limits. We specify the warranty document in full before contract.

Substrate Preparation — The Part That Determines Whether Coating Works

Silicone coating adheres to the existing membrane, not to the building. If the existing membrane has areas of delamination, blistering, open seams, or failed flashings, the coating bridges those defects and fails at the same location — often within 2-3 years. Substrate preparation is the majority of the labor cost in a silicone coating project and is where we will not cut corners.

Our substrate prep sequence: pressure wash at 3,500+ psi to remove dirt, chalk, and biological growth; probe every seam and flashing for delamination; mechanically bond all delaminated areas; replace failed flashings with new sheet-good details; apply primer where manufacturer requires it; inspect the prepared surface before coating begins. We do not start coating application until the substrate inspection is complete and documented.

Fort Worth's summer construction environment affects silicone coating application. Silicone requires a clean, dry substrate — application over moisture or below the dew point causes adhesion failure. We schedule silicone coating application in the early-morning window before afternoon humidity rises, and we do not apply when surface moisture is present. Fort Worth's July-August dew point profile sometimes limits our application windows to early morning.

We will walk the roof, pull cores to verify insulation condition, document substrate quality, and tell you whether coating or replacement is the honest scope — with cost comparison.
