Measure total ridge and hip length. The calculator divides by coverage per bundle and adds waste.
📐 Formula
Bundles = ⌈(Ridge Length × (1 + Waste%)) ÷ Coverage per Bundle⌉📝 Example Calculation
70 ft of ridge + hip, 5% waste: • 73.5 ft → 3 bundles at 33.3 ft/bundle
💡 Pro Tips from Roofers
- Measure hips AND ridges.
- Install from opposite prevailing wind.
- Use ridge vent under caps for ventilation.
