From Metal to Modified Bitumen: The Right Coating for Your Commercial Roof

September 19, 2025

The Weathertite Approach: Matching the Right Solution to Your Roof

As a facility director or property manager in Central Florida, your commercial roof is a vital asset, and choosing the right maintenance solution is a critical business decision. While a full roof replacement is a costly and disruptive option, an advanced commercial roof coating can extend its life, enhance its efficiency, and provide superior protection.

The key to a successful project lies in selecting the right coating for your specific roof type. At Weathertite Coatings, we don't believe in a one-size-fits-all approach. With our specialized expertise in elastomeric and silicone coatings, we provide tailored solutions for a wide range of commercial roofing substrates. Understanding the right product for your roof is the first step toward securing your investment.


Single-Ply Membranes (TPO, PVC, EPDM)

Single-ply roofs are popular for their durability, but they can degrade over time from intense UV exposure and thermal expansion.

  • Silicone Coatings: A silicone coating is an ideal solution for these roofs. When the surface is properly prepared, silicone adheres exceptionally well, creating a seamless, waterproof membrane that provides superior UV protection and long-term durability. It is a proven method for restoring and extending the life of your TPO, PVC, or EPDM roof.
  • Elastomeric Coatings: While elastomeric coatings can be used, they often require a specialized primer or bonding agent to ensure proper adhesion, making silicone a more direct and reliable choice.

Asphalt-Based Roofs (Modified Bitumen & Built-Up Roofs)

These traditional roofs are common on commercial buildings but can suffer from weathering, cracking, and deterioration over time.

  • Silicone & Elastomeric Coatings: Both silicone and elastomeric coatings are highly effective on asphalt-based roofs. A thorough cleaning and priming of the surface are crucial. Once prepared, either coating forms a flexible, reflective barrier that protects the asphalt from UV damage and moisture intrusion, preventing premature cracking and leaks. The choice often depends on factors like roof slope and your long-term maintenance goals.

Metal Roofs

Metal roofs are known for their strength and longevity, but they are vulnerable to rust, fastener failure, and thermal movement.

  • Silicone & Elastomeric Coatings: Both coatings are excellent for metal roofs. They seal all fasteners and seams, preventing leaks and providing a robust layer of rust-resistant protection. The high reflectivity of both coatings dramatically reduces heat absorption, making them a dual-purpose solution for both structural integrity and energy efficiency.

Concrete Roofs

Concrete roofs are durable but can be susceptible to water absorption and moisture-related issues.

  • Silicone Coatings: Silicone is the superior choice for concrete roofs. Its non-porous and waterproof properties create an impermeable barrier that prevents water from penetrating the concrete slab. Proper surface preparation is key to ensuring maximum adhesion and long-term waterproofing, making silicone the go-to solution for this challenging substrate.

Spray Polyurethane Foam (SPF) Roofs

SPF roofs are known for their insulation properties, but require a top coat for UV protection.

  • Silicone & Elastomeric Coatings: Both coating types work well for protecting SPF roofs from UV degradation, which can cause the foam to deteriorate quickly. The high reflectivity of both silicone and elastomeric coatings shields the SPF layer, preserving its insulative properties and extending the roof's lifespan.
