Roof Deck Tape

Roof Deck Tape™ is a 40-mil, self-adhering tape composed of a non-slip film coated with an aggressive asphalt-based adhesive system. The adhesive is protected by a disposable release liner, which is removed prior to application. Use Roof Deck Tape to tape all joints and seams of a roof deck, preventing water, air and moisture from entering the structure. Once the joints and seams are taped, the roof may be covered with roofing felt, a synthetic underlayment or self-adhering underlayment like those offered by MFM. Some building codes require a roof deck seam tape when used under roofing felt or synthetic underlayment.

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!
