How Much Square Footage in a Bundle of Cedar Shingles

Cedar shingles are a classic roofing and siding choice known for their natural beauty and durability. Coverage per bundle varies by shingle size, exposure, and profile, so understanding typical bundle sizes helps builders estimate material needs accurately. This article breaks down standard cedar shingle sizes, how many bundles make up a square (100 square feet), and practical tips to plan a cedar project efficiently.

Cedar Shingle Sizes And Coverage

Coverage per bundle depends largely on the shingle’s dimensions and how much of the shingle is exposed once installed. Common cedar shingles come in different profiles, such as edge-grain or taper-cut, and lengths typically range around 18 to 24 inches. Exposure, the vertical amount visible after installation, also varies, with typical exposures around 5 to 6 inches for traditional singles. Because of these factors, bundles do not uniformly cover a fixed number of square feet across all products. Instead, manufacturers provide a coverage estimate per bundle, which should be used for planning, with adjustments for waste and overlaps.

Typical Coverage Ranges By Shingle Type

The following ranges reflect common market offerings in the United States. Always check the product packaging or the manufacturer’s spec sheet for precise coverage per bundle.

• Traditional cedar shingles (18–24 inches long, 5–6 inch exposure): Approximately 20–25 square feet per bundle.
• Square-edge or edge-grain cedar shingles (longer lengths, similar exposure): Roughly 22–28 square feet per bundle.
• Cedar tapers (taper-cut, shorter exposure, standard lengths): About 20–26 square feet per bundle.

Notes: The range accounts for variations in exposure, cut, and thickness. For estimating, many professionals assume about 22 square feet per bundle for mid-range cedar shingles and then add extra bundles for waste, overlaps, and cutting around features like chimneys and vents.

Bundles Per Square And Project Planning

Since one square equals 100 square feet, estimating the number of bundles requires an average coverage per bundle. A practical rule of thumb is to plan for roughly 4.0 to 5.0 bundles per square for typical cedar shingles, depending on the exact product and desired exposure. This translates to about 80 to 125 bundles for a 1,000-square-foot roof, before waste and flashing are considered. For siding projects, the calculation follows the same logic but uses the siding’s exterior face area instead of roofing exposure.

Calculating Coverage For Your Project

To estimate cedar shingles needed, follow these steps:

1. Measure the total area to cover (roof or siding) in square feet.
2. Find the manufacturer’s coverage per bundle for the chosen shingle style. Use the lower end to account for waste and cuts.
3. Divide the total area by the bundle coverage to estimate bundles required.
4. Add 5–10% for waste, especially on roofs with complex geometry or many cutouts.
5. Convert bundles to squares by dividing the total bundles by the shingles per square (roughly 4 bundles per square as a general rule, though this depends on product).

Example: For a 1,500-square-foot roof with cedar shingles rated at 22 square feet per bundle, the calculation would be 1,500 / 22 ≈ 68 bundles. Add 10% waste: 74 bundles. In squares: 74 bundles / 4 ≈ 18.5 squares; round up to 19 squares.

Factors Affecting Coverage And Waste

Several practical factors influence how much coverage a bundle yields in real conditions:

• Exposure choice: Deeper exposure reduces effective coverage per bundle and increases waste due to more cuts.
• Shingle profile and thickness: Heavier, thicker shingles with larger overlaps consume more material per area.
• Roof geometry: Complex roofs with valleys, hips, and dormers require more cuts and waste.
• Starter course and end cuts: Wasted waste often occurs at eaves, rakes, and edges where custom cuts are needed.
• Weather and handling: Damaged shingles from handling and humidity may be discarded, increasing waste.

Planning should include a contingency for these factors, typically 5–15% of total material, depending on roof complexity.

Practical Planning Tips

These tips help ensure accurate ordering and efficient installation of cedar shingles:

• Consult the exact product sheet: Always verify bundle coverage and recommended exposure from the specific cedar shingle brand.
• Use a spare bundle strategy: Purchase a few extra bundles to accommodate waste and future repairs, especially for siding projects.
• Consider batch color matching: Cedar tones vary between batches; plan for color consistency across the project by ordering in multiple complete batches if needed.
• Account for roof pitch: Higher-pitched roofs may require more waste due to increased edge cuts at hips and ridges.
• Coordinate with underlayment and flashing: Ensure the correct sequence to prevent rework and ensure water resistance.

Common Mistakes To Avoid

Avoid underestimating bundles for cedar shingles by neglecting waste or overestimating coverage. Do not assume uniform coverage across brands or styles. Double-check exposure settings, shingle length, and thickness. Miscalculations lead to color imbalances and difficult material shortfalls mid-project.

Conclusion

Understanding the typical coverage per bundle for cedar shingles helps homeowners and contractors plan with confidence. Because bundle sizes vary by product, always verify the manufacturer’s specs for the exact shingle you choose and adjust for waste, roof geometry, and exposure. With careful calculation, projects stay on budget and finish with a consistent, durable cedar appearance.
