Why Corn-Based Roof Rejuvenation Is the Next Frontier

Published by Roof Rejuvenate USA

When you think of corn, you probably picture dinner plates or fuel pumps — not rooftops. But that’s changing fast. Thanks to new advancements in bio-based chemistry, corn is becoming the foundation for one of the most important innovations in modern roofing: asphalt shingle rejuvenation.

Recently, Roofing Magazine featured an article announcing that Colorbiotics, a Sika company, has developed a new corn-based roof rejuvenation solution, now offered exclusively through Roof Rejuvenate USA’s authorized dealer network. This partnership is setting a new industry standard for sustainability, performance, and long-term roof preservation.

A Breakthrough in Roof Maintenance

Asphalt shingles are the most common roofing material in North America, but they’re also highly vulnerable to age and weathering. Over time, the oils that keep shingles flexible dry out, causing brittleness, cracking, and granule loss — the leading reasons homeowners face costly roof replacements.

Traditional solutions have included surface coatings or sealants, but these often create a film on the roof rather than addressing the underlying problem. Roof rejuvenation takes a completely different approach: it restores the shingle’s lost oils at the molecular level, returning flexibility and extending the roof’s lifespan by years.

The latest step forward? Corn-based rejuvenators.

The Power of Corn-Based Technology

Unlike earlier formulations that relied on methyl esters or synthetic solvents, this new rejuvenation oil from Colorbiotics is derived entirely from corn — a renewable, natural, and environmentally friendly resource.

Here’s what makes it groundbreaking:

✅ Eco-Friendly & Sustainable

Corn oil is biodegradable, renewable, and free from harsh chemicals or solvents. It offers homeowners a greener, safer way to maintain their roof — especially important in regions where stormwater runoff and environmental impact matter.

✅ Restores Shingles at the Molecular Level

Corn-based rejuvenators penetrate deep into aging shingles, restoring essential oils that allow the asphalt to remain flexible. The result is a stronger bond between the asphalt and granules, reducing shedding and extending roof life.

✅ No Harsh Methyl Esters

Many competing “rejuvenators” rely on methyl esters — chemical derivatives that can actually break down the natural oil structure within shingles. The corn-based formula avoids that, preserving the integrity of the material for superior long-term performance.

✅ Proven by Independent Testing

This isn’t theory. Independent lab testing has confirmed measurable improvements in flexibility, permeability, and granule adhesion — the three key factors that determine a roof’s lifespan.

Why This Matters to Homeowners

The average asphalt roof replacement can cost anywhere from $12,000–$25,000 or more. Roof rejuvenation offers an alternative at roughly 20% of the cost of replacement, with no mess, no tear-off, and no landfill waste.

With a simple one-time spray application, shingles regain their flexibility and weather resistance — helping protect against leaks, wind damage, and premature failure.

And with corn-based rejuvenation, homeowners can now protect their investment with a product that’s safer for their family, their property, and the environment.

Why It’s the Future of Roofing

As insurers, contractors, and homeowners seek cost-effective and sustainable maintenance options, rejuvenation is quickly becoming the “fourth R” of roofing — repair, replace, restore, rejuvenate.

What makes this the next frontier is its balance of science, sustainability, and real-world value. A single treatment can extend the functional life of an asphalt roof by five to ten years — buying homeowners valuable time before replacement becomes necessary.

And for property managers and HOA boards managing dozens or hundreds of roofs, the math is even more compelling: rejuvenation can defer millions in capital expenditures while improving roof performance portfolio-wide.

A Partnership Backed by Industry Leaders

Roof Rejuvenate USA is proud to partner with Colorbiotics, a division of Sika Corporation, to bring this cutting-edge corn-based technology to market across North America.

Together, we’re leading a movement toward more sustainable, longer-lasting roof maintenance — one that benefits homeowners, contractors, and the planet alike.

See the Results for Yourself

If your roof is between 5–15 years old, rejuvenation may be the perfect solution to restore life and flexibility before costly repairs or replacement.
