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.

Roof Rejuvenate recently earned USDA BioPreferred Program certification, recognizing its bio-based formulation made from renewable, plant-derived ingredients. The certification verifies that the product contains 95% bio-based content and, importantly, has no added PFAS. 

Unlike coatings or treatments that rely on synthetic chemistry or petroleum-based additives to “seal” the surface of a roof, Roof Rejuvenate works from the inside out—restoring flexibility and vitality to aging asphalt shingles by penetrating into the shingle’s core and replenishing lost oils. This process helps reduce cracking, curling, and granule loss while extending the useful life of the roof. 

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.
