Formula

Adjusted Length = (Ridge Length + Total Hip Length) × (1 + Waste %)

Worked example

40 ft of ridge plus 80 ft of hips with 10% waste requires about 132 linear ft of material.

What to keep in mind

  • Measure all applicable ridges and hips along the roof surface.
  • Product-specific exposure and overlap can change piece counts.
