WHAT IS GREENER SHINGLES?
Asphalt roofs usually start showing some signs of oxidation after ﬁve to ten years depending on region and environmental conditions. The shingle’s essential oils dry up losing the ability to hold the granular in place. Greener Shingles uses a 95% bio-based rejuvenator that can reverse years of oxidation. This environmentally safe process replaces oils and resins that have been lost through the natural aging process, which also increases shingle ﬂexability.
