Advances in white solar reflective elastomeric roof coating over the past 15 years have resulted in a durable roofing system that addresses the need for energy-efficient roofing. These roof coatings offer three primary benefits – durability, sustainability and solar reflectivity. When combined, these benefits provide homeowners with value, protection and reduced energy costs.
Reflective roof coatings work like mirrors, reflecting the sun’s radiant energy back into space. When initially applied, solar reflective roof coatings can provide a solar reflectance of up to 80%.
Standard asphalt roofing reflects only around 25% of sunlight. This is because it is typically covered with a gray aggregate (mineral) and a black substrate which allows considerable heat absorption.
The solar reflectivity of white elastomeric roof coatings can reduce the surface temperature of asphalt roof surfaces if it is applied on to it. The roof surface temperature reduction associated with white elastomeric roof coatings equate to lower cooling costs to homeowners and promote the life of the roof.
In comparison to white elastomeric solar reflective roofing systems, the installation of built up asphalt roofs is an energy consuming process, with the end result being a roof which has a relatively short service life of 8-10 years.
It is estimated that 7% to 10% of landfills are made up of roofing waste due to the fact that traditional built up asphalt roofing requires frequent replacement.
All that is required to extend the life of a white solar reflective roof coating is annual cleaning and an additional coating application as per the recommendations of the manufacturer.
As solar reflective roof coating systems only require supplemental coats to extend their life once the initial system has been installed, they help reduce the amount of waste that goes to landfills associated with traditional roofing tear-off.
