A Breakthrough in Roof Rejuvenation: The Science Behind Corn-Based Rejuvenation

At Roof Rejuvenate USA, we’ve just introduced the world’s first corn-based asphalt shingle rejuvenator 🌽 —and it’s changing the way homeowners think about roof care. 📍 Exclusively available through Roof Rejuvenate USA’s Authorized Dealer Network.

Why Your Roof Needs More Than Just a Cleaning

By the time your roof hits the 8-10 year mark, your shingles have already started to dry out. This is when oxidation kicks in—stripping the shingles of their natural oils, causing brittleness, and leading to granule loss (those tiny protective bits that keep UV rays and moisture at bay).

Our breakthrough formula, made from natural corn oil, works by penetrating deep into the shingle—not just coating the surface like other treatments. It reintroduces essential oils, restoring flexibility and locking in granules from the bottom up. And unlike other roof treatments, our product doesnt rely on soy methyl esters—industrial-grade degreasers used in many conventional products. Our formula is all-natural, non-toxic, and USDA certified bio-based.

🌦 What the Lab Testing Proves

3rd party independent testing through PRI Asphalt Technologies using real, 15-year-old residential shingles. After simulating 5 years of weathering, the shingles treated with our corn-based rejuvenator showed:

• 53% better granule retention

• 66.7% improved cold-weather flexibility

• 24% stronger tear resistance

• A visibly refreshed look—giving your roof a second life

A Smart Investment in Your Home

Rejuvenating your roof is about protecting your investment—helping your shingles last the full 25 to 30 years they were designed for. With our advanced, all-natural formula, you can maintain your roof before damage sets in, extending its life safely, effectively, and sustainably.

Soy vs. Corn: What Sets These Roof Rejuvenators Apart?

We’ve used soy-based rejuvenators in the past, and they delivered solid results in restoring flexibility and improving granule retention. However, our new corn-based formula offers several key advantages. Unlike soy methyl esters, which are industrial-grade solvents often used as degreasers, our corn-based product is gentler on shingles while delivering deeper penetration into the asphalt base. It restores essential oils without softening or compromising the structure of the shingle. Independent lab testing also showed superior performance in granule retention, cold-weather flexibility, and tear strength—making it a more effective and sustainable long-term solution.
