Absolutely! A roof coating system not only provides excellent reinforcement and waterproofing to aged roofs, but they can also provide UV protection against premature aging and roof failure to new roofs.
High reflectivity is often promoted when speaking of a roof coating system because it provides two important functions, increased energy efficiency and conservation, and UV protection. Everyone is familiar with and wants to benefit from lower energy usage and costs but they often times do not realize that with those benefits comes an even better benefit – UV protection.
Roof coating systems that use highly reflective topcoats are packed with UV blocking pigments that protect your roof from the harmful and damaging UV rays the sun emits. The greater capability the roof coating has to reflect these rays away from the rooftop, the greater protection and increased longevity your roof has. White reflective roof coatings reflective a majority of the sun’s heat (aka UV rays) away from the building back into the atmosphere. This keeps your buildings’ ambient air temperature cooler, which is responsible for lowering your energy usage and costs and provides your roof with greater protection from essentially drying out – becoming brittle, cracking, splitting, separating, tearing and eventually leaking. A roof needs to expand and contract with changing air temperature fluctuations throughout the day. Unfortunately, the harmful UV rays dry out the surface of the roof, slowly destroying its ability to remain flexible. This is the reason they say the sun is the most destructive and damaging element to your roof.
With that all said, a roof coating system using a highly reflective topcoat is an excellent preventative measure for a new or aged roof as they increase your roofs lifespan, lower roof maintenance costs and protect your roof from the destructive UV rays from the sun. The AcryShield A590 topcoat is rated one of the highest reflective roof coatings in the industry. With an initial solar reflectance of 0.92 and a 3-year solar reflectance of 0.87, this roof coating is able to reflect almost all of the sun’s UV rays, leaving little for the roof to absorb any heat.
