What Is Metal Roofing?

Metal Roofing Benefits

Metal roofing is the second most popular roofing material in the United States–and for good reason. Metal roofs boast an impressive list of benefits and are one of the best roofing materials for durability, longevity, energy efficiency, sustainability and ROI.

In this guide, we’ll cover everything you need to know about metal roofing, including:

History of Metal Roofing

While metal roofing has recently surged in popularity amongst homeowners, it has dominated the industrial sector for centuries. Factories, barns, military barracks, warehouses and other industrial buildings have benefitted from the durability, longevity, high ROI and low-maintenance characteristics that only a metal roof can provide.

Historically, metal roofing wasn’t embraced by the residential sector as it was considered “too industrial looking” by most homeowners.

This changed when the Decraspray Company developed an emulsion coating made from road tar and stone chips during World War II. Designed to camouflage the highly reflective metal roofs of military buildings in wartime England, the stone-coating formula was developed to provide protection from German air raids. When the war was over, the stone coating had not only preserved the metal roofs, but the coating was practically impossible to remove. Decraspray saw the potential for stone-coated metal roofs as a residential roofing product and in 1957, the first stone-coated metal roof was introduced.

Types of Metal Roofing

Metal roofing is a fairly broad term for roofing products composed of various types of metal.

Common types of metal roofing include:

  • Aluminum
  • Copper
  • Corrugated
  • Standing seam
  • Stone-coated steel

The main difference between these types of metal roofing is appearance. As mentioned above, most metal roofing has an industrial look and feel, with stone-coated metal roofing offering the most design versatility to suit nearly any residential, commercial or industrial property.

Metal roofing is known as one of the most durable, longest lasting and energy-efficient roofing materials on the market.

Metal Roofing vs. Traditional Roofing Materials 

As mentioned, metal roofing is the second most popular roofing material in the U.S. As homeowner awareness continues to grow, so too does the market share of metal roofing. Here’s how metal roofing stacks up when compared to traditional roofing materials.

Asphalt Shingles

Asphalt shingle roofs are currently the most popular roofing material in the U.S. At their peak popularity, asphalt shingles were used on more than 70% of homes. The reason for the popularity of asphalt shingles is due to cost. Asphalt shingles are the cheapest roofing material on the market, however, homeowners have become painfully aware that, when it comes to roofing, cheaper isn’t always better. Asphalt shingles have significant shortcomings when it comes to longevity, energy efficiency and sustainability.

Lifespan: Traditional asphalt shingles need to be replaced as frequently as every 12 years, even sooner in regions that are prone to hail, tornados, hurricanes and harsh weather.

Energy Efficiency: Asphalt shingles absorb heat like a sponge and radiate heat down into the home below, even after the sun has set. When it comes to energy efficiency, asphalt shingles are one of the worst-performing roofing materials.

Sustainability: Since asphalt shingles are petroleum-based, they are often too toxic to recycle. Since asphalt roofs need to be replaced so frequently, they wind up contributing 11-13 million tons of waste to landfills every year. That’s equivalent to 3,068 Olympic-size swimming pools filled with old asphalt shingles.

Metal shingle roofing products, such as DECRA Shingle XD, provide similar aesthetics of asphalt shingles, but with the durability and longevity that only metal can provide.

Clay or Concrete Tiles

Many architectural themes rely on the look of Spanish or Mediterranean tile roofs. While tile is a critical design element, it is also one of the heaviest, most fragile and high-maintenance roofing materials on the market. Clay tile roofs are so fragile that just walking on them for routine maintenance can cause damage, so you can only imagine what would happen to a clay tile roof in regions prone to hail, hurricanes, tornadoes, high winds and storm debris. Clay and concrete tile roofs are also extremely heavy.

Why does the weight of the roof matter? A building bearing an excessively heavy roof load is considered top-heavy and prone to side forces. Heavy roofing materials pile excessive weight up at the top of the home, adding to the roof load and the construction materials required to support it. Clay tiles can absorb up to 15% of their weight in moisture, adding weight stress to the supporting roof structure. Here’s how tile weighs in compared to other roofing materials:

  • Metal Roofing: Weigh up to 1.6 lbs. per square foot
  • Wood Shingles/Shake: Weigh up to 4.5 lbs. per square foot
  • Asphalt Shingles: Weigh up to 5 lbs. per square foot
  • Clay or Concrete Tile: Weigh up to 10 lbs. per square foot

Metal tile roofing products provide the classic look of tile without sacrificing performance.

Wood Shingles or Wood Shake

Wood roofs were extremely popular until the early 1900s when more durable roofing materials entered the market. Wood shingles and wood shake roofs are plagued with issues that require ongoing maintenance and repairs, including:

  • Fading to a gray after brief exposure to the elements.
  • Cupping and splitting, making wood roofs extremely susceptible to wind uplift.
  • Wood can foster mold, requiring extra chemical treatments and cleaning.
  • Wood roofs are extremely flammable and require flame retardants and other treatments.

Fortunately, metal shake roofing products provide the rustic appeal of wood with the industrial strength of metal.
