Metal Roofing: A Comprehensive Guide

For New Hampshire homeowners, metal roofing is a popular choice due to its durability, strength and ability to withstand harsh New England weather conditions, especially heavy snow.

Advantages of Metal Roofing

Metal roofs offer numerous benefits, making them an attractive option for many homeowners

  • Longevity: Metal roofs can last between 40-70 years, depending on the material, which is significantly longer than traditional asphalt roofing materials that have an estimated life expectancy of roughly 12-20 years.
  • Durability: If installed correctly, some metal roofs can sustain wind gusts up to 140 miles per hour, will not corrode or crack, and may be impact-resistant.
  • Safety: Metal roofs will not spark and ignite into flames during a wildfire or lightning strike.
  • Energy Efficiency: Metal roofs reflect the sun’s UV and infrared light rays that contribute to roof surface radiant heat, which can result in a 10-25% reduction in cooling costs.
  • Environmentally Friendly: Metal roofs not only have 25-95% recycled content, depending on the material used, but are also 100% recyclable at the end of their life as a roof.

Metal Roofing Durability in Winter vs Asphalt Shingles

Metal roofs are highly durable and can withstand extreme New England weather conditions better than asphalt shingles. They do not absorb water, making them resistant to damage from ice and snow. In contrast, asphalt shingles can absorb moisture, leading to potential damage when water freezes and expands. Moreover, metal roofs can endure wind gusts up to 140 miles per hour, making them more resilient against winter storms compared to asphalt shingles. As for roof shoveling, metal roofs require less hands-on maintenance and also feature less ice dam buildup.

Metal Roofing Longevity vs Asphalt Shingles

The lifespan of a roof is a critical factor when considering roofing materials. Metal roofs have a significantly longer lifespan than asphalt shingles. On average, a metal roof can last anywhere from 40 to 70 years or longer, while asphalt shingles typically have a lifespan of 12 to 20 years. This longevity makes metal roofing a cost-effective choice in the long run despite its higher upfront cost.

Types of Metal Roofing

Metal roofing comes in various forms, including large flat sheets and shingles. The types of metal roofing include:

  • Hidden Fastener Metal Roofing: These systems are secure and resistant to erosion because there are no fasteners (screws) exposed.
  • Exposed Fastener Metal Roofing: These types offer a nice, clean look even with visible screws.
  • Stamped Metal Roofing: This is one of the newest types of metal roofing, known for its ability to resemble other roofing materials.

Common Metals used in Metal Roofs

Common materials used for metal roofing include galvanized steel, aluminum, copper, zinc, and tin.

  • Galvanized steel is a popular choice for metal roofing due to its good structural characteristics and high melting point, giving it a Class A fire rating. 
  • Aluminum roofing is lightweight, malleable, and corrosion-resistant, making it ideal for coastal climates. 
  • Copper roofing is highly durable and has a unique aesthetic appeal, but it’s more expensive than other materials.
  • Zinc roofing is also more expensive, but it has a lower galvanic reaction when combined with galvanized steel or aluminum.
  • Tin roofing, while less common today, is affordable and resistant to corrosion. However, it’s not as durable as the other materials. 

Each roofing material has its own advantages and considerations, so the choice depends on the specific needs and budget of your roof installation project. It is highly recommended that you request a free estimate from Nick Tracey Roofing, as our roofing team will provide you with a firm quote.
