Metal Roofing is generally made of steel, aluminum, galvalume, or copper. Most metals require
a Baked-on paint finish to prevent rusting. Copper is a natural metal which weathers without corroding and requires no preventive coating. Copper is typically used for special features of a roof system. Metal roofing products can be stamped into many shapes and are typically installed as an interlocking panel system. The primary benefit of metal roofing is longevity, manufacturers routinely offer 50 year warranties for their products.
