Most asphalt roof shingles can last 20–40 years, yet typical roof warranties span approximately 15–25 years. This means total roof replacements happen more frequently than the shingles’ estimated lifespan. That's where asphalt shingle rejuvenation comes in. If treated early enough you can extend the life span of your roof shingles much longer than originally estimated.
Greener Shingles asphalt rejuvenator was inspired by a patented asphalt rejuvenator used to preserve the oil in roads, driveways and parking lots. Greener Shingle's bio-based asphalt rejuvenator technology was then reformulated for asphalt roofing shingles.
After completing a series of vigorous lab tests the Greener Shingles rejuvenator has demonstrated that it can help reduce the effects of aging after being applied to asphalt shingles, improve granular adhesion, help waterproof the surface and improve fire retardancy.
This environmentally safe solution improves shingle flexibility which helps the expansion and contracting that happens to the shingle throughout the day, helping the shingles to last longer, rather than cracking after being dried out.
