RoofTape is a fleece-backed self-adhesive tape consisting of butyls and EPDM rubber. RoofTape has excellent adhesive qualities and is highly resistant to temperature extremes and harsh UV rays. Its unique properties allow it to conform to just about any roof surface, providing a durable watertight seal. RoofTape is intended for sealing seams, fasteners, edge transitions, small cracks, vents and drains before application of GacoRoof 100% Silicone Roof Coating.
