Green Roof Renew

Born from Science. Built for Your Roof.

In 2020, Iowa State University engineers set out to develop asphalt binders from local feedstocks amid supply chain disruptions — and stumbled onto something unexpected: a soybean oil emulsion that could rejuvenate aging asphalt shingles.

The researchers behind the formula hold PhDs in asphalt science, and the treatment they developed is as safe as it is effective — non-toxic to humans, animals, and plants.

Our soybean-oil concentrate is 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.
