Metal roofs are durable and beautiful and a great investment. The beauty, durability, and ease of maintenance are quite appealing. Metal roofs can best be catagorized into two types, those attached with exposed fasteners and those attached with hidden fasteners.
The standing seam metal roof is the most durable and maintenance-free metal roof in the world. It is usually constructed of a heavy-duty steel panel which is seamed together. There are no exposed fasteners with this system. Standing seam metal roofs are among the most expensive metal roofs in the market. They come is a wide variety of beautiful colors and a few different profiles. Once installed, they will last virtually a lifetime!
Metal roofs with exposed fasteners, often called screw-down roofs, are very popular and very durable. Snap lock metal roofing, often referred to as a standing seam metal roof, uses a hidden fastener system. The hidden screw method not only provides better cosmetics but secures your roof in a more stable manner resisting those elements that cause leaking from screw holes “growing” over time, the “wobble” affect.
Metal roofs are a premium product and cost somewhat more than a 20 year warranty asphalt/fiberglass shingle roof; however a metal roof can cost substantially less than many of the high-end architectural shingles now being sold. Additionally, metal roofs have many advantages and benefits over asphalt/fiberglass shingle roofs.
Metal roofs are very tough and highly resistant to hail damage… much more so than asphalt/fiberglass roofing shingles. Many metal roofing products have the highest impact resistance and hail rating granted by the insurance commissions in the hail belt regions of the U.S.
