MFM Peel & Seal is the original, patented self-stick roll roofing. Peel & Seal roll roofing is ideal for roofs and surfaces that are difficult to waterproof and can be used on many surfaces including: metal roofs, mobile homes, RVs or trailers, and sunroofs. MFM Peel & Seal can also be used as flashing around ducts, vents, chimneys, air conditioning units, or even on gutters. MFM Peel & Seal is made of aluminum composite foil, polymer films, and a rubberized asphalt adhesive back, making it flexible and self-adhering. Peel & Seal roll roofing will not tear, crack or dry out over time. It is designed specifically to reflect heat and resist water and exposure to other elements without any additional coverage needed. Peel and Seal can be installed on an EPDM roof, but you must prime it with either WeatherBond Multi Purpose Primer or Mule Hide Tape Primer.
