This Isn’t Sweet Corn: Field Corn in Everyday Products — Corn Shingles


By Tara Desmond • January 29, 2026

Field corn isn’t just for livestock feed or fuel — it’s also showing up in unexpected products, like roofing.


Roof Rejuvenate is made with corn oil from field corn and was recently added to the USDA BioPreferred® Program, earning certification for 95% biobased content. The program highlights products made mostly from renewable agricultural materials.


Asphalt shingles naturally contain oils that keep them flexible. Over time, heat and sunlight cause those oils to dry out, which can lead to cracking, curling, and granule loss. Roof Rejuvenate works by reintroducing oil into aging shingles, helping restore flexibility and durability from the inside out.


The corn oil formula also helps improve resistance to sun damage and makes conditions less favorable for mold, moss, and algae. The product is third-party lab tested, free of added PFAS, and carries a five-year warranty.


For farmers, this is another example of how field corn supports new, everyday uses, turning crops from the field into products people rely on in their homes.
