Is there a Difference between White Roof Paint and White Roof Coating?

Cool-Roof-ImageYES! White roof paint does not have the durability, strength, protection, reflectivity, and waterproofing capabilities of a white roof coating.

Often time’s people refer to white roof coating, as white roof paint, when in fact, coating and paint are very different. White roof paint cannot withstand the typical elements a roof endures. It becomes brittle and will peal, chip and crack within a season. A white roof paint does not protect your roof from the sun’s heat by reflecting the sun’s UV rays away from the building or provide waterproofing. It was thought that they would provide energy savings being that they are white, however; because white roof paint cannot reflect the heat away, it does not add value to saving energy usage or costs.

White roof coatings contain high reflective pigments to ensure the sun’s heat is absorbed as little as possible. This allows the building to remain cooler, providing cost savings on energy consumption to cool the building.  The high reflective pigments in white roof coatings also lengthen the life span of the roof by reflecting the damaging UV rays away from the building instead of absorbing them. The sun’s UV rays are the leading cause of roof degradation because the intense heat breaks down and dries out ingredients that allow for the roof to expand and contract during weather and temperature fluctuations. Therefore, the highly reflective white roof coatings keep the roof from cracking, becoming brittle, and aging prematurely. The polymers used in a white roof coating allow for superior bondage to the existing roof membrane. This is necessary as it provides excellent waterproofing and ensures durability and protection to the roof and building below.
