Spray Silicone Sealants

Spray silicone sealants demonstrate strong adhesion to a wide range of common roof substrates. Compatible surfaces include metal, concrete, masonry, wood, asphalt, built-up roofing, and spray-applied polyurethane foam. They can also be applied over existing single-ply membranes such as EPDM and TPO, providing a seamless waterproofing layer that eliminates the expense and labor of complete substrate tear-off.

Yes, high-performance spray silicone sealants feature hydrophobic properties engineered specifically to resist permanent ponding water. Unlike water-based acrylic coatings that can soften, blister, or delaminate under prolonged standing water, moisture-cure silicone maintains its bond and physical integrity. This makes spray silicone an effective restoration choice for low-slope and flat roof decks prone to standing water accumulation.

Spray silicone sealants function as reflective cool roof coatings that reflect solar radiation away from the building envelope. By preventing rooftop heat absorption, the coating keeps internal facility temperatures cooler during hot weather. This reduction in thermal load helps commercial facilities and residential properties decrease air conditioning usage, protect roofing substrates from thermal shock, and lower overall utility expenses.

Spray silicone sealants are supplied in multiple volume sizes to support projects of any scale. Container options range from sample and 1-gallon cans up to 4-gallon and 5-gallon pails for localized repairs or detailing. For large commercial roof restoration projects requiring continuous airless spray application, material is supplied in 55-gallon drums as well as bulk 180-gallon to 265-gallon pallet configurations.

Spray silicone sealants are engineered for efficient application using commercial airless spray rigs designed for high-viscosity elastomeric materials. Using airless spray ensures a uniform dry film thickness across large flat or low-slope surfaces. In addition to spray application, the material can also be applied using heavy-nap rollers or brushes for detailing flashings, penetrations, parapets, and vertical architectural wall surfaces.

Manufacturer material warranties are available up to 20 years depending on the specific system configuration, application rate, and project specifications. Contractors can select tailored system specifications matching their roof condition and durability requirements. Pricing generally ranges between $1.25 and $1.64 per square foot for qualifying 20-year restoration systems, ensuring long-term peace of mind and waterproof performance.
