Commercial Roofing Coatings and Systems

For roofs with ponding water or low-slope drainage challenges, solvent-free 100% silicone coatings like SiliconEx 500 offer permanent water resistance. For flexible membrane waterproofing across multiple substrates, elastomeric solutions like SealEx 100 provide up to 500% elongation to seal cracks and prevent leaks. The ideal choice depends on substrate compatibility, slope, ponding conditions, and whether an elastomeric basecoat is required.

Commercial roof coatings adhere to a wide variety of roofing substrates. Depending on the specific system, coatings can be applied over metal, concrete, masonry, wood, asphalt shingles, built-up roofing (BUR), modified bitumen, spray polyurethane foam (SPF), and single-ply membranes such as TPO and EPDM. Primers may be recommended for certain asphaltic surfaces to ensure optimal adhesion and prevent bleed-through.

Reflective cool roof coatings, such as SolarEx 300 and SiliconEx 500, reflect solar radiation and UV rays away from commercial buildings. By preventing solar heat from absorbing into the roof deck and interior spaces, these coatings reduce indoor temperatures. This reduces the strain on HVAC equipment and lowers utility bills, extending roof lifespan while supporting commercial facility energy efficiency goals.

When applying silicone coatings over asphalt shingles, built-up roofing, or bituminous surfaces, asphalt oils can bleed through into topcoats. A water-based bleed-blocking primer, such as BleedEx 400, seals the substrate. This prevents asphalt bleed-through, maintains topcoat color and solar reflectivity, and improves adhesion between the underlying roof substrate and subsequent protective coating layers.

Commercial roof coating systems are designed for versatile contractor application. They can typically be applied using standard roofing brushes, rollers, or commercial-grade airless spray equipment. For large-scale projects, airless spray application at appropriate pressure allows contractors to cover large surface areas efficiently while ensuring consistent membrane thickness across flat, low-slope, or vertical architectural surfaces.

Yes, restorative commercial roof coatings offer an effective alternative to complete roof replacement. Applying elastomeric, silicone, or acrylic restoration systems over aged but structurally sound built-up, single-ply, or metal roofs seals leaks, restores weatherability, and reinforces granule retention. This restoration process typically avoids costly tear-offs and extends service life by years with proper surface preparation and maintenance.
