Roof Rejuvenate, 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 rehydrates the shingle to “plump 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.
