🛠️ How This Calculator Works
Enter eave and rake lengths. The calculator adds them, applies waste, and divides by bundle coverage.
📐 Formula
Bundles = ⌈(Eave + Rake) × (1 + Waste%) ÷ Coverage per Bundle⌉📝 Example Calculation
80 ft eave + 60 ft rake = 140 ft → 147 ft with 5% waste → 2 bundles
💡 Pro Tips from Roofers
- Install with adhesive strip facing up.
- Offset joints from first-course shingles by 6".
- Also install at rakes in high-wind areas.
- Pre-cut starter saves 15-20 min per 100 ft.
❓ Frequently Asked Questions
What is starter strip?
A narrow shingle strip installed along eaves and rakes before the first course, providing adhesive to seal the first row.
Can I use cut shingles instead?
Yes, but manufactured starter strips are faster and provide more consistent wind resistance.
How many linear feet are in a bundle of starter shingles?
Roughly 100 to 120 linear feet for most purpose-made starter strip — the exact figure is printed on the wrapper. Cutting your own starter from 3-tab shingles yields about 33 linear feet per bundle.
How much starter strip do I need?
Measure eave + rake length. One bundle covers about 105 ft. Add 5% waste.
