Protective Roof Coatings Over SPF

SPF requires protection from the sun's ultra-violet radiation, moisture and foot traffic. This coating helps to protect and seal the foam from any damage from these or other elements. Some types of roof coatings can even add strenght to the roofing system and building structure.

Once the spray foam (SPF) has been applied to the proper thickness and finish specifications, a protective layer of elastomeric coating, or gravel is applied. This protective layer produces a durable weather resistant surface and that can be walked on for normal maintenance.

protective roof coatings over spfThe most common cool roof coatings used over sprayed polyurethane foam (SPF) and other roof deck surfaces are light/white colored. The most common types are:

Some suppliers and contractors use a thin layer of gravel spread over the foam. This system has been used very successfully, however, elastomeric coatings are more common. The coatings are spray applied as single component, or plural component system and can be silicone, acrylic, butyl rubber, polyurea, and different urethanes. The various materials all have different physical properties and vary in cost. Check with your supplier for more details.

Coatings are usually installed in two stages: a base coat, and a final top coat. Granules are often embedded into the final coat and offer added protection against mechanical ultra-violet damage.

In time, these coatings will require maintenance, or replacement, but just like paint on your house, they can be removed and re-applied to keep your SPF roof system in peak performance for decades.

An SPF roof, like most other systems, will expand and contract during different climate conditions. It is very important that the protective coating is able to expand and contract with the SPF or serious damage can result in the form of cracks or delamination. This physical characteristic is called elongation and is something your materials suppliers can help you with to properly match the SPF and coating system to roof system and climate.

Within this Canada regional spray foam site, you will find information and specifications on spray foam insulation and spray foam roof systems contractors including closed-cell and open-cell insulation information. Alberta spray foam insulation adheres to just about everything so it can be installed over concrete, wood, steel, and most existing roof systems which saves on the expense of roof removal and landfill fees. SPF Roofing installers can spray apply a tapered roof system with the foam which eliminates the need for costly tapered insulation systems. The cants and vertical wall terminations are also spray applied making them an integral part of the roof system and minimizing additional component costs.

The city of Alberta provides spray foam insulation for use in both homes and commercial buildings. Spray Foam can be applied in Attics and Wall Insulation as the most common place in the house. We also see insulation in Canada for Basements, Roof Insulation, and Floors and Garages.
