Key Article Takeaways

  • Contractors purchase materials through wholesale supply houses (e.g. ABC Supply, Beacon) at 15% to 25% lower prices than retail big-box stores.
  • Architectural shingles range from $35 to $50 per bundle ($105 to $150 per SQ) wholesale depending on warranty tier.
  • Asphalt prices fluctuate with global crude oil prices, as asphalt flux is a refined petroleum byproduct.
