Roof Coating Helps Sustain Environment By Lowering Energy Usage And Extending Roof Life

The use of elastomeric coatings contributes to sustaining the environment by lowering energy usage and reducing the amount of old roof materials going to landfills. William A. Kim, technical service manager, explains "Nearly 17 percent of all electricity consumed in the U.S. is used to cool buildings. Coating black roofs white can help reduce that number by increasing energy efficiency." Studies show that buildings with the white coating consumed nearly 22 percent less energy for air conditioning in the summer than one with an uncoated black roof. Additionally, the coating also reduced energy demand by 4 percent in the winter. The EPA awards its Energy Star to white and reflective roofing materials, recognizing their value in promoting energy efficiency and conservation.

White roof coatings also contribute to a healthy environment by extending the lifespan of black roofs. "Six percent of waste material dumped in landfills consists of old roofs," notes Kim. "White coatings help roofs last longer by reducing the dramatic changes in temperature that cause roof wear and tear, and that benefits our environment by reducing the size of our landfills."
