Metal Roofing Materials Pros & Cons:

  • standing-seam Metal roofs can be made from a variety of metals and alloys including
    — Galvanized G-90 steel (hot-dip zinc galvanized high-end steel), and G-60 steel (a less expensive, thinner-gauge steel, often used in low-end, lower-cost corrugated and ribbed metal panels)
    Galvalume steel (zinc and aluminum coated steel) has a more expensive and longer-lasting coating compared to G-90 galvanized steel.
    — stone-coated steel (G-90 galvanized steel), aluminum, copper, zinc, terne (zinc-tin alloy), and stainless steel.

  • The downside of galvanized steel (G-90, and especially G-60) is that it can corrode, eventually, especially when exposed to moist, salt-spray environment such as when your home is situated near the ocean or near the coastal areas.

  • Steel is the most frequently used material in both residential and commercial applications, mainly due to its lower cost.

  • Aluminum is the second most popular material. It is more durable and longer lasting than steel, but only costs a fraction of the price of premium metals, such as copper or zinc.

  • Aluminum is also one of the best metals to use for roofs located in coastal areas (think those beach homes), where there is a heavy presence of salt spray in the environment.

  • Copper roofs are the most durable and can last for hundreds of years. However, due to prohibitively high cost, few people choose to install an entire roof made from copper. Instead, home and business-owners choose copper for architectural details/accents on the roof (bay windows, towers, porches, low slope roof sections, Etc.).
