Metal Roof Types

When considering metal roof life expectancy it’s important to know that the lifespan varies depending on the type of metal roof. There are two main types of metal roofs: standing seam metal roofs and screw-down panel metal roofs.

Standing Seam Metal Roofs

Standing seam metal roofs are made up of metal roofing panels joined at an underlying seam. This type of roof has an impressive lifespan with some lasting between 50 and 75 years.

They’re a popular choice for residential and commercial buildings due to their durability and modern aesthetic.

Screw-Down Panel Metal Roofs

Screw-down panel metal roofs consist of corrugated steel or aluminum panels with exposed screws. These roofs have a shorter average lifespan typically between 20 and 30 years and are more commonly used for agricultural buildings barns silos and other structures.

Advantages of Metal Roofs

Metal roofs offer a variety of benefits for homeowners and businesses alike. Some of the most significant advantages include their eco-friendliness wind resistance and fire resistance.


Metal roofs are an environmentally responsible choice as they are often made from high percentages of recycled metal and can be fully recycled once replaced. This makes them a sustainable and eco-friendly roofing solution.

Metal roofs are designed to withstand high winds with some types capable of handling wind speeds up to 180 mph. This is considerably higher than the 140 mph wind resistance offered by most asphalt shingles and wood shakes.

Fire and Hail Resistant

Metal roofs are flame-retardant providing excellent protection against fire and extreme weather conditions like hail. This resistance can lead to savings of up to 30% on homeowners’ insurance policies making it an attractive benefit for those considering a new roof.

Low Maintenance

  • Long-lasting paint such as Kynar 500 finish to minimize fading and chalking
  • Resistance to pest damage as metal does not warp or buckle like wood
  • High-performing components provide excellent protection against leaks and moisture damage

In conclusion metal roofs are a durable long-lasting and eco-friendly roofing option with the ability to withstand various weather conditions. To ensure the longest possible life expectancy for your metal roof proper installation and maintenance are essential.

Factors Affecting Metal Roof Lifespan

Several factors contribute to the lifespan of a metal roof including:

  • Type of metal roofs: Metal roofs come in various types like standing seam metal roofs lasting 50-75 years and screw-down panel metal roofs with a lifespan of 20-30 years.
  • Proper installation: Ensuring that your metal roof is well installed is crucial for its longevity. Choosing an experienced roofing contractor is vital for this process.
  • Finishing: Applying a high-quality finish like the Kynar 500 finish can significantly protect and extend the life of your metal roof.
  • Weather: The average lifespan of metal roofs depends on the typical weather conditions in your area. Mild weather can lead to a longer-lasting roof while extreme weather may shorten the lifespan.
  • Ventilation: Ensuring proper attic ventilation is critical for the metal roof’s lifespan. Proper ventilation removes excess moisture thereby reducing the risk of leaks and other damages.
