Fortify is designed for asphalt shingle roofs that are 0 to 6 years old. The treatment bonds at the molecular level with your shingles, blocking UV degradation, granule loss, moisture infiltration, and biological growth before damage starts.
Fortify upgrades a Class 1 shingle to perform like Class 3 or 4 against hail and wind. One application extends roof life by up to 15 years.
