Metal Roofing Facts

Residential Roofing Project

If you are considering installing a new metal roof on your home or commercial property here are the most essential metal roofing facts.

  1. Steel is the most frequently used material in both residential and commercial applications, mainly due to its lower cost.
  2. Steel roofs need to be coated with a special protective (galvanic) coating to prevent corrosion. – Galvanized and Galvalume steel roofing systems are pre-coated by the manufacturer and do not require any further coating.
  3. It is typically possible to install a metal roof over an old roof, thus eliminating the extra cost and hassle associated with the shingle tear-off (be sure to consult your contractor about the possibility of “over-top” installation for your specific roof). — This is generally possible because metal is an extremely light-weight material.
  4. Unlike many other roofing materials, a metal roof can easily be installed in the winter.
  5. Metal roofs come in two general styles: vertical panels and interlocking shingles
  6. Many modern styles of metal shingles are manufactured to imitate the look of slate, clay tile, cedar shake, and in some cases even the traditional look of asphalt shingles.
  7. Metal roofs such as aluminum or steel shingles can last for 50 years and often longer, while copper and zinc roofs can often last well over 100 years. – This means that a typical metal roof will last about 3-7 times longer than a typical asphalt shingles roof, which usually needs to replaced every 12-17 years.
  8. Metal roofs offer the best protection against ice, snow, and ice dams.
  9. Metal roofs will not rot, split, crack, dry-out, chip, warp, leak, unlike all other common roofing materials.
  10. Generally metal roofs require none or minimal maintenance.
  11. Metal roofs can be cleaned with water.
  12. Metal roofing is the only TRULY green material in the roofing industry, because it uses the least amount of resources during the manufacturing process, contains no petroleum by-products, and can always be recycled.
  13. A metal roof will not increase the likelihood of your home getting struck by a lightning.
