The aggressive asphalt-based adhesive used in Roof Deck Tape self-seals around roofing fasteners such as nails, screws and staples to maintain a waterproof barrier. Additionally, it readily sticks to plywood, OSB, rigid foam insulation, metal and other common roof deck materials.

Roof Deck Tape may also be used to prepare a low-slope substrate for Peel & Seal® by taping wider than normal joint and seam gaps. Roof Deck Tape is the easy-to-use and economical way to prevent water from leaking into the building between the roof deck panels!
