Developments in white solar reflective elastomeric roof coating over the course of the past decade have resulted in a long-lasting roofing system that is also energy-efficient. These roof coatings offer three key benefits – sustainability, durability and energy efficient solar reflectivity. In combination, these three benefits provide homeowners with reduced energy costs, value and protection.
Reflective roof coatings work like mirrors, reflecting back the sun’s energy. When first applied, solar reflective roof coatings can provide a solar reflectance of up to 80%, which means that only 20% of the sun’s energy is being absorbed as heat.
Conventional built up asphalt roofing reflects only around 25% of sunlight. This is because it is normally covered with a gray mineral and a black substrate which causes heat to be absorbed.
The solar reflectivity of white elastomeric roof coatings can reduce the surface temperature when applied over flat built up asphalt roof surfaces. The reduction in roof temperature associated with white elastomeric roof coatings mean lower cooling costs to homeowners.
When compared to white elastomeric solar reflective roofing systems, the installation of asphalt roofs is an energy consuming process, with the end result being a roof that has a relatively short service life of 8-10 years.
It is estimated that around 8% of landfills are comprised 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 periodic cleaning and an additional coating application as per the manufacturers recommendations.
As solar reflective roof coating systems only require supplemental coats to extend their lifespan once the initial system has been installed, they help reduce the amount of waste that goes to landfills associated with traditional roofing tear-off.
