Manufactured in Somerset, Pennsylvania, Roof Rejuv makes a plant-based spray treatment that restores flexibility to aging asphalt shingles and extends the life of existing roofs. Created by industrial chemist Chris Nagle alongside a construction and restoration team with more than 40 years of experience, the solution is designed to reduce roof-replacement waste and carbon emissions. Independent Intertek testing found a 97% reduction in water vapor through treated used shingles and 84% greater granule retention than untreated samples.
