The Environmental Impact of Metal Roofing vs. Asphalt Shingles

Why Roofing Materials Matter for Sustainability

The choice of roofing material affects not only durability and energy efficiency but also environmental sustainability. For Arizona homeowners in Sedona, Prescott, Cottonwood, and Camp Verde, where the climate is extreme, selecting a roof that minimizes waste, energy consumption, and pollution is a priority.

Metal roofing has gained popularity as an eco-friendly alternative to asphalt shingles, which contribute to significant landfill waste and require petroleum-based production. In this guide, we’ll break down the long-term environmental benefits of metal roofing and why it’s a more sustainable option for homes in Arizona.


The Environmental Challenges of Asphalt Shingles

1. Short Lifespan & Frequent Replacements

  • Asphalt shingles typically last 15-30 years, but in Arizona’s intense heat, their lifespan is often shorter due to UV degradation.
  • Frequent roof replacements increase material waste and contribute to landfill overflows.

2. Petroleum-Based Production & Carbon Footprint

  • Asphalt shingles are made from petroleum-based materials, making them reliant on fossil fuels.
  • The production process emits volatile organic compounds (VOCs), contributing to air pollution and greenhouse gas emissions.

3. High Landfill Waste

  • 75-80% of asphalt shingles end up in landfills after roof replacements.
  • Old asphalt shingles take centuries to decompose and leach chemicals into the environment.

Fact: According to the EPA, asphalt shingles contribute to 11 million tons of waste annually in the U.S. alone.

Why Metal Roofing is the Sustainable Choice

Unlike asphalt shingles, metal roofing is designed for longevity, recyclability, and energy efficiency.

1. Long Lifespan & Reduced Waste

  • Metal roofs last 40-70 years, reducing the need for frequent replacements.
  • Homeowners in Prescott and Cottonwood save money and reduce waste by choosing a roof that lasts twice as long as asphalt shingles.

2. 100% Recyclability

  • Metal roofing is 100% recyclable at the end of its life cycle.
  • Many metal roofs contain up to 95% recycled content, further reducing environmental impact.
  • Unlike asphalt shingles, which often end up in landfills, metal can be repurposed for new construction.

3. Energy Efficiency & Lower Carbon Footprint

  • Metal roofing reflects solar heat, reducing cooling costs by 15-25% in Arizona’s extreme heat.
  • Lighter-colored metal roofs and reflective coatings improve thermal efficiency.
  • Lower energy use means reduced carbon emissions from air conditioning.

Comparing Metal Roofing and Asphalt Shingles: Environmental Impact

Factor Metal Roofing Asphalt Shingles
Lifespan 40-70 years 15-30 years
Recyclability 100% recyclable Most end up in landfills
Energy Efficiency High – reduces cooling costs Low – absorbs and retains heat
Carbon Footprint Low – reflects heat, reduces AC use High – made from fossil fuels
Landfill Waste Minimal – can be repurposed High – 75-80% of old shingles go to landfills

4. Metal Roofing & Solar Energy

  • Metal roofs are ideal for solar panel installation, enhancing sustainability.
  • Solar panels last 25+ years, aligning well with the long lifespan of metal roofing.
  • Homeowners in Sedona and Prescott benefit from lower energy bills and increased home value when combining metal roofing with solar.

The Future of Sustainable Roofing

With advancements in eco-friendly construction, roofing materials are evolving to reduce environmental harm.

1. Cool Roof Technology

  • Modern metal roofing options feature high-reflectivity coatings that improve energy efficiency.
  • These coatings help reduce the urban heat island effect, making cities like Phoenix and Prescott Valley cooler.

2. Recycled & Sustainable Metal Roofing Materials

  • Manufacturers are producing metal roofs from post-consumer and post-industrial recycled materials.
  • This shift reduces reliance on mining and virgin resources, lowering environmental impact.

3. Green Roofing Systems

  • Some homeowners are integrating vegetative or green roofs, which provide natural insulation and stormwater management.
  • While more common in urban areas, green roofing is gaining traction in sustainable home design.
