  • Recyclable
  • Can be installed over an existing roof [no tear-cost]
  • Warranties like weather-tight or paint or labor

Disadvantages

  • Oil canning, chalking or fading are aesthetic concerns
  • Interaction with materials like copper, iron, treated lumber, concrete and bricking can result in quick corrosion or total failure of galvalume roof sheets

Aluminum roofing

Advantages

  • Highly recyclable
  • Lightweight, durable, and strong
  • Rust resistant
  • Mid-range price
  • Easily available

Disadvantages

  • Natural color but undergoes weathering overtime
  • Lightweight so prone to denting
  • Expands and contracts due to thermal fluctuations causing increased noise, oil canning, and so needs regular maintenance on visible fasteners

Zinc roofing

Advantages

  • Long lasting [100+ years]
  • Eco-friendly
  • Cuts down home heating & cooling cost
  • Metal has its own protective layer, so protects against corrosion as well as corrects panel marking and scratching on its own
