METAL ROOF UNDERLAYMENT
For ultimate protection from the elements, it is vital to include a quality moisture barrier when installing a long-lasting roofing system. Roofing underlayment adds an extra layer of moisture barrier between your metal roofing panels and any substrate beneath them. Without proper underlayment, metal roofs are subject to leakage or entrapped moisture due to vapor diffusion or air exfiltration.
At MetalMax, we offer two options for metal roof underlayment: synthetic underlayment and peel & stick underlayment. Synthetic underlayment for metal roofing is created by weaving/spinning together polypropylene, or polyethylene, and a polymer to form a light-weight protective barrier. This is often the better option to the more traditional felt underlayment. Peel and stick underlayment is a self-adhesive water-resistant product. It contains a peel-off membrane on one side and a rubberized asphalt material on the other side to reduce water penetration.
Our synthetic underlayment is a highly-engineered, coated, and woven synthetic material that offers a reliable secondary layer of protection under all types of sloped roofing material. Unlike felt, its recyclable polyolefin construction doesn’t expand or contract and is inert to mold and mildew growth. It is 100% synthetic and is unaffected by water. It is engineered to lay flat and will not buckle or wrinkle when exposed to temperature and moisture fluctuations on the roof.
Unlike oil saturated felts, our synthetic underlayment does not dry out, leach oils in the heat, nor does it become stiff, difficult to roll or crack in the cold.
PEEL & STICK UNDERLAYMENT
Our Peel and Stick Roof Underlayment is a modified rubberized asphalt underlayment with a tough, rugged surface and a self-sealing lap system. It is slip resistant, has a synthetic polymer surface, and is self-adhering. Peel & Stick underlayment is designed for 2:12 or greater sloped roof applications subject to the effects of ice damming and wind driven rain.
This type of underlayment can be used under many types of roofing materials including metal, tile, shakes, slate, and both asphalt and synthetic shingles.
