How to Reduce Roofing Material Waste
Waste can account for 5–22% of total materials — $500 to $3,000+ per job.
Strategy 1: Optimise Sheet Lengths
Custom-cut sheets eliminate ordering waste. Savings: $300–$800 per 200m² roof.
Strategy 2: Smart Cutting Layouts
Mirror cuts from one side of a hip on the opposite side. Reduces waste by 30–50%.
Strategy 3: Order Accurately
Use digital tools like our Quick Estimator to calculate exact quantities.
