SPF roof systems should be inspected semi-annually and after events that could cause physical damage. Small (less than 3″ diameter) dents, cracks, punctures from dropped tools, wind driven debris can be repaired with an elastomeric sealant compatible with the SPF and coating system. More extensive damage can be repaired by reapplying SPF.
Typically SPF roof systems are re-coated every 10 – 15 years, depending on the type and thickness of coating used and factors specific to the roof (such as wind erosion effects, hail, foot traffic, abuse, etc.) Recoating extends the service life of the SPF roof system.
