Western Colloid Products

 Founded in 1979, Western Colloid is recognized in the roofing 
 industry as a leader in fluid applied roofing and reflective coating 
 systems. Western Colloid uses innovative, state-of-the-art facilities to
 manufacture asphalt emulsions and water based coatings. Teamed
 with companies such as Rohm and Haas, Western Colloid develops
 and manufactures some of the finest roof coatings available.

 Fluid applied roofing results in a seamless finish, which makes future
 inspections and maintenance easy.  The fluid applied approach also
 allows roofs to be resurfaced, thereby extending their service lives  indefinitely. Our protective coatings are designed to meet the high stress requirements of today’s roofing membranes. Our elastomeric reflective coatings are energy saving and highly durable. They protect the roofing membrane by stopping the UV degradation and by reducing the “thermal shock” that all roof membranes experience.

Western Colloid is the most comprehensive asphalt coating manufacturer in the Western United States. Unlike most manufacturers, Western Colloid offers several coatings to meet specific asphalt and budget needs. If you are a building owner or manager, we can recommend and specify systems that will meet your needs. If you are a contractor we can deliver the quality products and services that will help make you successful.

We are committed to producing systems that are environmentally friendly and energy efficient. As an Energy Star® partner, Western Colloid proudly offers several coatings with the Energy Star® label. As a leader in roof maintenance systems, Western Colloid is committed to reducing landfill use by indefinitely extending the life of existing roof systems. 

With manufacturing centers conveniently located throughout the Western U.S., our products and technical staff are always handy. Call today for comprehensive information on any of our products, and find out how Western Colloid can make your upcoming maintenance project a guaranteed winner.
