Terra Seal is a self-adhering clay or concrete tile roof underlayment that withstands elevated rooftop temperatures and has exceptional nail pull-through resistance. It comprises high-grade polyester fabric laminated to high-temperature, self-sealing asphalt adhesive protected by a release liner removed during installation.
