What is granule loss?
Granules are the protective outer layer of asphalt shingles that shield your roof from UV rays, weather, and everyday wear. As shingles age, these granules loosen and wash away, leaving your roof more vulnerable to damage.
Renueit®17 helps lock down loose granules, restore flexibility, and help preserve qualifying asphalt shingle roofs for an additional 17 years, without the cost of a full replacement.
