Formula
See calculator inputs and results panel for step-by-step math.Pick a roof size preset or type your footprint / eave measurements.
Enter sq ft per bundle, panel, or roll from your product label.
Keep the 10% buffer on for valleys, hips, and cut waste.
Use bundles, linear feet, or sq ft in the results panel for your order.

Common real-world scenarios where this tool saves time.
2,000 sq ft roof at 33.3 sq ft/bundle with 10% waste ≈ 66 bundles.
1,800 sq ft at 32 sq ft/panel with buffer ≈ 62 panels.
160 ft perimeter eaves → order ~176 ft with 10% seam overlap.
120 ft eave × 1 ft depth = 120 sq ft soffit area.

| 1×6 | Standard eave | Match eave run |
| 1×8 | Deep fascia | Match eave run |
| 1×10 | Boxed cornice | Add cut buffer |
Multiply footprint by pitch multiplier — use Roof Area Calculator first.
Add 10–15% for valleys, hips, and starter strips.
Read sq ft per bundle on each wrapper — brands differ.

One roofing square is 100 sq ft. Three-tab bundles often cover ~33.3 sq ft each — about 3 bundles per square.
10% is standard for simple gable roofs; 15% for complex hips and valleys.
Measure vertical rise over 12 inches of horizontal run — a 6/12 pitch rises 6 inches per foot.
Use Metal Roofing Calculator for panel counts, or enter panel sq ft in bundle mode tools.
Common K-style gutters ship in 10 ft sections — divide total linear feet by 10 and round up.
Measure from the wall to the outer edge of the fascia — often 12–24 inches (1–2 ft).
Yes — use Roofing Material Calculator for bundles plus underlayment roll counts.
No — it is a planning tool. Confirm quantities with your roofer or supplier before purchase.
Fascia board length estimates run locally — EverydayTools does not upload fascia calculator dimensions.
Estimates only — not professional roofing advice. Verify quantities with a licensed roofer before purchase.
