Roof chemistry built for long-term performance

By Jesse Sanchez. 

Contractors and homeowners are gaining new roof maintenance options through engineered asphalt rejuvenation chemistry designed to extend roof life and support long-term infrastructure sustainability. 

SoyLei, a materials-science company focused on asphalt-compatible chemistry, is positioning its APEX-1132™ technology as part of a broader infrastructure and roof maintenance platform designed to support contractors, recyclers and homeowners. The company recently outlined how its roof rejuvenation products differ from franchise-style roof treatment operations and commodity oil-based applications. 

According to SoyLei, APEX-1132 is engineered specifically to interact with asphalt at the molecular level rather than simply coat the roof surface. The company said the treatment is designed to penetrate aging asphalt shingles, restore flexibility and improve granule adhesion while helping maintain the shingle adhesive seal strip. 

SoyLei describes the product as a “5:1 modified soybean-oil concentrate engineered to penetrate asphalt shingles, restore shingle flexibility, improve granule adhesion and reactivate the asphalt in the shingle adhesive seal strip so shingles stay sealed, held down, resist blow-off and help extend roof life.” 

The company emphasizes that APEX-1132 is not a paint, cosmetic coating or emulsified biodiesel product. Instead, the technology was developed through research at Iowa State University and continues to be supported directly by the original chemical and civil engineering team behind the product. 

SoyLei also highlighted its contractor-focused business structure. Unlike some roof rejuvenation businesses that operate through franchise agreements or restrictive territories, the company said contractors maintain ownership of their customer relationships and business branding. Contractors can purchase products in multiple package sizes ranging from one-gallon containers to bulk programs intended for larger-scale operations. 

Beyond roofing, SoyLei said its chemistry platform supports broader asphalt recycling and infrastructure applications. The company explained that its additives are designed to help producers increase recycled asphalt pavement and recycled asphalt shingle content while maintaining pavement durability and improving lifecycle performance. 

The company additionally noted that homeowners can contact SoyLei directly to discuss roof maintenance questions and product applications with the founders.
