Roof Maxx is an environmentally friendly, natural oil treatment for asphalt roofs that can extend their lifespan by five years per application, ideally starting when a roof is 5 – 10 years old, depending on the regional climate. The treatment is safe for humans, pets, plants, and the environment, and helps reduce landfill waste by prolonging the lifespan of asphalt shingles. Even older roofs can benefit from Roof Maxx, following minor repairs if needed.
