Roof Rejuvenate USA, in collaboration with global construction materials leader Sika, commissioned an independent third-party study through PRI Asphalt Technologies, a recognized authority in asphalt shingle testing. The study used 15-year-old asphalt shingles from a real residential roof and subjected them to a 1,500-hour accelerated weathering test, simulating five years of natural aging using industry-standard aging models.
The goal was to compare untreated shingles with those treated using the Roof Rejuvenate product. PRI evaluated critical performance metrics—including flexibility, durability, and overall longevity—and the results showed significant performance improvements in the treated shingles over the simulated 5-year period.

Corn-Based Rejuvenator
Crafted with a formulation featuring natural corn oil, this rejuvenator works at the molecular level to restore and protect aging asphalt shingles. Unlike surface-level treatments, it penetrates deep into the shingle, depositing oils into the base layer while filling microscopic voids created by oxidation over time. This oil reintroduction process causes the shingle to “puff back up,” improving flexibility and locking granules in place from the bottom up. The result is a revitalized, more resilient shingle that resists mold, moss, and algae growth—thanks to the restored, oil-rich surface they can’t easily colonize. It’s a sustainable, high-performance solution designed to extend shingle life while remaining environmentally responsible.
Overall Conclusion from 1,500-Hour (5-Year) Accelerated Aging Study
🏆 Best granule adhesion – 53% better retention than untreated shingles, which means better protection and longer shingle life.
🏆 Superior flexibility – 66.7% improvement over untreated shingles, helping resist cracking in cold conditions.
🏆 Stronger shingle structure – 24% higher tear strength in machine direction
🏆 Noticeable visual restoration – A visible difference in shingle color, giving roofs a newer, revitalized look.
What is it, and what does it do?
Roof Rejuvenate is a 96% USDA Certified bio-based rejuvenator. Unlike traditional treatments, Roof Rejuvenate
works deep within the core of each shingle, repairing the chemistry that naturally breaks down over time. Say goodbye to cracking and curling as our all-natural, non-toxic formula restores flexibility and prevents future damage. With increased granule adhesion and UV aging reversal, your roof becomes stronger and more resilient than ever before. Invest in Roof Rejuvenate today for a lasting solution that keeps your home safe and beautiful.
How is it different from other products on the market?
Roof Rejuvenate stands out from the crowd by not relying on soy methyl esters, industrial-grade solvents often used in similar products. Instead, our unique technology operates on a molecular level, targeting the very foundation of your shingles. By restoring the asphalt base within the lower tab of each shingle, we ensure comprehensive rejuvenation without compromising on quality or resorting to harsh chemicals. With Roof Rejuvenate, you get a truly innovative solution that prioritizes effectiveness and sustainability, safeguarding your roof for the long haul.
HOW EFFECTIVE IS ROOF REJUVENATION?
The Smarter, More Affordable Way to Extend Your Roof’s Life...
Roof Rejuvenate doesn’t just improve your roof’s appearance—it brings it back to life. Our treatment restores shingles to like-new condition, significantly extending the life of your roof for years to come.
REPLACE LOST OILS
Natural agricultural oils have been used for the past 15 years to rejuvenate asphalt roads to replace the oils that are lost through years of aging.
INCREASED GRANULE ADHESION
Rejuvenating shingles improves granular adhesion and increases flexibility, helping to prevent damage from wind and hail.
STOP MOSS GROWTH
When applied, Roof Rejuvenate effectively smothers moss and algae, inhibiting further growth. The oils in the product also create an environment where mold cannot thrive. The dead moss will wash away after a thorough rain.
IMPROVES SHINGLE COLOR AND APPEARANCE
Untreated shingles exhibit a notable decline in appearance due to granule loss. Treated shingles have a darker appearance, closer to what they looked like when new.
DECREASES OXIDATIVE AGING
Reduced oxidative aging (carbonyl index) and decreased mass loss indicate extended roof lifespan and enhanced durability.
INCREASES FLEXIBILITY AND STRENGTH
Applying Roof Rejuvenate to your roof adds oils back and restores flexibility and strength to your shingles.
