The Early 1900s Building That This Company Calls Home 

2021 marked the 60th anniversary for MFM Building Products. The company, founded in 1916, celebrated the longevity and legacy of their company, but their corporate headquarters have existed for nearly twice as long! The Eldridge-Higgins Building that MFM calls home is a historic building on the National Registry of historic places. With MFM’s Expansion Project in 2021 marking their 60th anniversary, new offices in the main headquarters building were constructed and a new, state-of-the-art Research & Development laboratory was added to the historic site MFM calls home.

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!
