Roller-Grade Silicone Roof Coating

SKU: HS-3201-HB-5

Restore, waterproof, and lengthen the life of your roof with our 100% Silicone Roof Coatings. Our roof coatings possess over 95% solids content, meaning what you put on the roof stays there after it cures. 

Designed to be applied with a roller rather than sprayed, our Roller-Grade Silicone Roof Coating can be installed in excess of 70 wet mils in a single coat while still delivering all the benefits of our High Solids Silicone Roof Coating.

Available in: White, Tan, Light Gray, Dark Gray, and Black, in 1 and 5-gallon pails.

Application: Roll-apply only.


HS 3200-HB Roller-Grade Series Solvent-Free Silicone Roof Coating is a one-component, moisture curing silicone rubber roof coating system designed for use on existing smooth surface BUR, granulated cap sheet, well-adhered acrylic coating, concrete, metal, spray foam, and various single-ply membranes.

The system provides long-term protection because it resists weathering, aging, oxidation, wind-driven sand, rain and snow, the effects of ozone, ultraviolet radiation and the temperature extremes typically found on roofs. With its high solids content and absence of hydrocarbon solvents, HS 3200-HB Series can be applied in excess of 70 mils in a single coat without blistering, while maintaining maximum adhesion.

In most situations, our silicone adheres to the existing substrate without the need of a primer, saving you time and money.

Resistance to UV rays, ponding water, oxidation, wind-driven sand, rain, and snow, and temperature extremes allows our roof coatings to provide long-term protection. Because of our coatings’ high reflectivity, you can expect to save up to $.50 per square foot on your energy bill after installing a silicone roof coating.

Storage and Shelf Life: HS 3200-HB Series High-Build Silicone Roof Coating has a recommended shelf life of 12 months from the date of manufacture when stored in unopened containers between 40°F and 80°F. Refer to product packaging for date of manufacture.


Prep: Prior to starting your roof project, prep the roof by power-washing, removing dirt and debris, and making any necessary repairs. Ensure roof is completely dry prior to applying silicone. For more detailed preparation instructions, view our Technical Resources page.

Mix: It is recommended that any silicone product be mixed with a drill mixer for ~5 minutes prior to application.

Application: The application rate and method for our High-Build Silicone Roof Coating depends on the substrate you are restoring. Our Silicone Coverage Guide is a great tool to determine how much material you’ll need for the job and at what rate you need to apply it.

Equipment: The coating should be applied by a medium nap roller only. Spray-equipment is not recommended. For small touch-up work, a brush may be used.

Cure Time: Our High-Build Silicone Roof Coating cures in 1-4 hours under normal weather conditions and is tack-free in 1-2 hours. Because conditions vary, it is recommended that you exercise caution prior to walking on recently applied coating.

Weather Restrictions: To ensure optimum performance, it is recommended that you do not apply this product when surface temperatures are below 40 degrees. In cold-weather applications, material should be kept indoors until immediately before application. It is also recommended that you do not apply this material while rain is falling. Rain will not cause silicone to wash off, but the substrate will become wet and will negatively impact adhesion.
