Commercial Waterproofing in Miami
— Decks, Balconies & Roof Systems

Yes — when the existing insulation is dry and the membrane is structurally sound, silicone coating is an excellent option. It restores reflectivity, seals minor cracks and seam edges, and provides 10–15 more years of roof life at 30–40% of full replacement cost. We assess eligibility with an infrared moisture scan — coating over wet insulation accelerates failure.

A roof membrane is a continuous waterproof layer installed as a complete roofing system. A roof coating is a fluid-applied layer applied over an existing membrane to extend its life. Coatings are thinner (40–80 mils) and rely on the existing membrane for structural support. Membranes are independent systems. Coatings are generally a maintenance/extension tool; membranes are a replacement system.

It depends on the existing substrate condition. If the deck structure is sound, an injection-grouting or below-deck system can be applied without removing the finished surface. If the existing substrate has failed or is saturated, the finish must be removed to address the problem at the membrane level. We assess the correct approach at the on-site visit.

Waterproofing in some commercial applications requires a building permit in Miami-Dade — particularly when structural deck repairs are part of the scope. We assess permit requirements at the proposal stage and handle all permit filings where required.

Quality silicone coatings from Tremco, Henry, and similar manufacturers last 10–15 years in South Florida when applied at the correct thickness (20+ DFT mils) over a sound substrate. Miami's UV exposure actually benefits silicone — it's more UV-stable than acrylic coatings and outperforms acrylic in high-sun applications.
