⛰️ Ridge Cap Estimator – Roofing Ridge Cap Bundle Calculator
Calculate ridge cap bundles based on total ridge length for accurate roofing estimates
Calculate how many ridge cap bundles you’ll need for your roofing project. This estimator accounts for total ridge length, bundle coverage, and waste buffer. Optionally, include cost per bundle to estimate your budget.
Measure the total length of all ridges across the roof. Use a tape measure or building plan. Most ridge cap bundles cover about 33.3 ft. Always confirm with your manufacturer. Add extra for cuts, overlaps, and mistakes. Recommended: 5–15%. Enter the price per ridge cap bundle to estimate total project cost.Result will appear here
💡 Tip: Most ridge cap bundles cover ~33.3 ft. Add waste to avoid shortages.

✅ Best Practices:
• Always round up to the nearest bundle — never order fractions.
• Complex roofs with multiple ridges require higher waste allowance.
• Store ridge caps in a dry, elevated location before use.
• Schedule delivery close to installation to prevent weather exposure.
• Double-check coverage on the packaging before finalizing your order.
❓ FAQ - Ridge Cap Questions
Q: What is a ridge cap?
A ridge cap is a specially designed shingle that covers the peak (ridge) of a roof, protecting it from leaks.
Q: Why add waste?
Waste covers cutting, overlapping, steep pitches, and installer margin.
Q: Can I use regular shingles instead?
Some roofers cut 3-tab shingles into ridge caps, but factory-made caps are stronger and last longer.
Q: How many bundles do I need for multiple ridges?
Measure all ridges, add them together, then run the calculation with the total length.
