100% Silicone Roof Coating

GacoRoof 100% Silicone Roof Coating creates a seamless membrane to seal and repair existing roofs and permanently protect against leaks, permanent ponding water and the damaging effects of severe weather. GacoRoof is available in several colors to enhance the aesthetics of any roof. Ideal for use on flat and sloped roofs including, but not limited to, large and small buildings, homes, garages and patio covers, sheds and barns, mobile homes, RVs and more.

100% SILICONE. The unique chemistry of GacoRoof offers peace of mind for a lifetime! It outperforms and outlasts acrylic, urethane, asphalt and Hypalon® coatings.

NO PRIMER REQUIRED. GacoRoof will adhere to most surfaces without a primer including built up roofs, cap sheet, metal, modified bitumen and sprayed polyurethane foam.

REMAINS PERMANENTLY FLEXIBLE. GacoRoof will stay flexible and maintain adhesion, even under permanent ponding water or snow pack. Other coatings become brittle and begin to degrade over time.

WITHSTANDS PERMANENT PONDING WATER. GacoRoof is an excellent choice for flat or sloped roofs. Extremely durable, GacoRoof will not soften, bubble or degrade under permanent ponding water.

NON-SACRIFICIAL. GacoRoof is unaffected by harsh UV rays and temperature extremes.

PREVENTS COSTLY TEAR OFFS. By recoating your weathered roof with GacoRoof, you not only extend the life of your roof, you avoid the need for a time-consuming and costly tear off.

  • 100% silicone roof coating 69% solids by volume.
  • Provides waterproof protection
  • Stands up to permanent ponding water without bubbling, peeling, or breaking down

    GACO Roof

    Posted by Susan on Dec 16th 2021

    Could not determine where leaks were coming from on a 20-year-old metal roof. One coat of Gaco did the job! My roof guy said it applied easily. Product shipped quickly and was received within 2-3 days.

    8 cans and 4 days later looks great. New flat roof leaked after 3 years, my roofer used GACO to fix the leak and I finished the job. Hopefully it is worth the investment of time and money,
