Liquid-applied roof coatings have proven themselves as useful tools for the roofing professional to restore and protect existing roofs. They can be extremely durable and used as the first-line of
defense in the roofing envelope, offering further protection to other components below.
The coating selected should be a result of a detailed assessment of the type and condition of the roof, the desired benefit, the capabilities and prescribed uses for the coating, and the economic considerations of the individual job. Liquid applied roof coatings provide a means of prolonging the life of an existing roof, and are often an effective alternative to re roofing.
Liquid roof coatings are after market products designed to extend life, seal leaks, provide a heat reflective or aesthetic function over existing roof surfaces. There are many products on the market ranging from asphalt based products, rubber solution (Hypalon, Neoprene, Silicone), water based Acrylic and other emulsions, and chemically curing systems such as Urethanes and now Liquid Roof.
The most widely used liquid coatings by the RV industry are Acrylic elastomeric products. The weakness of these products, however, comes from the fact that they are water-based emulsions, which makes them vulnerable to sudden showers or freezing temperatures soon after application. They have inherently poor resistance to standing / ponding water. Another drawback for the Acrylic products is that they do not work over single ply EPDM membranes.
