Insulated metal shakes offer a three-dimensional appearance that is a long-lasting alternative to conventional standing seam metal, cedar, or slate roofing. The roof system installs easily, keeping labor costs down; it withstands extreme conditions and is low maintenance throughout its long life. This course describes how the high performance of 24-gauge Galvalume® steel, a PVDF coating, and EPS insulation is combined to form a durable, energy-efficient, completely recyclable roofing product with a classic look.
