Gaco Roof Silicone

GacoRoof Silicone Coating

Flexible Yet Strong Protection For Your Oahu Roof

Product Description

GacoRoof is a Silicone product that stands up to permanent ponding water without bubbling, peeling or breaking down.

GacoRoof Silicone will stay flexible and maintain adhesion, even under permanent ponding water or snow pack.

And – GacoRoof does not require a recoat every 3 to 5 years. Do it once and you’re done.

Roof coatings made with acrylics, urethanes or asphalt soften under the stress of ponding water or snowpack. Eventually, these roof coatings will bubble and peel away from the substrate, leaving your roof vulnerable to leaks, rot, and decay.

However, GacoRoof’s 100% silicone formulation is designed to stand up to whatever the elements dish out. Silicone will withstand areas of ponding water without softening, bubbling or peeling from the substrate.

Acrylic, urethane and asphalt roof coatings decompose and wear away from the stress of harsh sunlight, UV rays, and freeze-thaw cycles.


Also available in 1 Gallon

  • Rust Prevention

Silicone’s unique chemistry creates a coating that will not degrade under ultraviolet light or from weather conditions. Silicone is an inert material, and does not decompose.

As acrylic and urethane coatings age, they become dirty and stained from exposure to blowing debris, dust and dirt. Roof Coatings may require recoating to maintain a clean appearance.

The smooth surface of GacoRoof Silicone Roof Coating offers excellent resistance to mold, mildew and staining and does not require recoating.

GacoRoof’s reflective white surface resists ozone and UV rays.

A Roof Coating That’s Good for the Environment!

GacoRoof’s versatility and reflectivity has a positive impact on the environment. GacoRoof’s ability to adhere to a wide array of substrates often eliminates the need for costly “tear offs” of existing roofing material that all too often needlessly end up as landfill.

GacoRoof’s high degree of reflectivity also helps the environment by keeping our cities cooler by reducing the growing problem of “Heat Island Effect”. Dark materials absorb and retain heat from the sun. GacoRoof reflects the sun’s rays.

In the sun a black surface can be as much as 70 degrees Fahrenheit or 40 degrees Celsius warmer than a white/reflective roof. When many dark or black roofs along with asphalt parking lots and streets are crowded together in a city the temperature phenomenon known as the “Heat Island Effect” occurs.

The term “Heat Island Effect” refers to urban air and surface temperatures that are higher than nearby rural areas.

Many U.S. cities and suburbs have air temperatures up to 10 degrees Fahrenheit (5.6 degrees Celsius) warmer than the surrounding natural land cover.
