Protective Coatings for SPF Roofs
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.
Once the 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.
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.
