How Many Shingles in a Bundle? Complete Answer
The Short Answer: It Depends on the Shingle Type
There is no single universal answer because “how many shingles in a bundle” changes with the shingle’s size, thickness and style. What is standardised is coverage: one bundle covers 33⅓ sq ft (3.1 m²). Manufacturers simply put as many shingles in the bundle as needed to hit that coverage. Here are the typical counts:
| Shingle type | Typical shingles per bundle | Bundles per roofing square | Bundle weight (approx.) |
|---|---|---|---|
| Three-tab (strip) shingles | 21–29 | 3 | 23–29 kg |
| Architectural / laminate shingles | 15–22 | 3 | 27–36 kg |
| Designer / premium shingles | 12–18 | 3–4 | 30–40 kg |
| Cedar shakes (wood) | Varies widely | 4–5 | 20–30 kg |
Notice the pattern: thinner three-tab shingles need more pieces per bundle to reach the same coverage, while thicker architectural shingles need fewer. The weight column matters too — a bundle of architectural shingles can weigh as much as a packed suitcase, which affects how you get them onto the roof.
What Is a “Roofing Square”?
Roofers in the US measure roofs in “squares”, where one square equals 100 square feet (9.29 m²). Since each bundle covers 33⅓ sq ft, three bundles make one square. This is why shingles are sold in bundles rather than individually — the trade thinks in squares.
In the UK the terminology is different. British roofers work in square metres and buy concrete or clay tiles by the thousand, but bitumen and felt shingles (sold by brands stocked in UK merchants) still follow the bundle convention with coverage stated on the packaging. Always read the coverage figure rather than counting pieces.
Why the Count Varies So Much
Shingle size
A standard three-tab shingle is about 91 cm × 30 cm (36″ × 12″), with only half of that exposed to the weather — the rest is hidden under the overlapping course above. Architectural shingles are the same nominal size but thicker and heavier, so fewer fit in a bundle of the same weight class.
Exposure and overlap
How much of each shingle shows (the “exposure”, usually 12.5–14 cm) determines how many you need per square metre. Steeper roofs and high-wind zones sometimes require reduced exposure, which means more shingles per square metre — and more bundles for the same roof.
Manufacturer packaging
Some manufacturers pack slightly more than the nominal 33⅓ sq ft to allow for cutting waste; others pack exactly to the figure. Two bundles from different brands can contain different numbers of shingles while covering the same area. Coverage, not count, is the number that matters when ordering.
How Many Bundles Do You Need for Your Roof?
Work it out in five steps:
- Measure the roof area. Measure each plane’s length × width in metres and add them together. (Our guide to how floor and roof areas are measured explains the technique, and you can adapt the same maths — or see how square footage is calculated for the full method.)
- Convert to roofing squares. Divide the total square metres by 9.29 to get squares (100 sq ft units).
- Multiply by 3. Three bundles per square is the standard.
- Add 10–15% waste. Cut shingles at ridges, valleys, hips and edges generate real waste. Complex roofs with dormers need closer to 15%.
- Round up. You cannot buy half a bundle, and running short mid-job is expensive.
Worked example: a simple gable roof of 120 m². 120 ÷ 9.29 = 12.9 squares. 12.9 × 3 = 38.7 bundles. Add 10% waste = 42.6, so order 43 bundles. At roughly 25 shingles per bundle for three-tab, that is about 1,075 individual shingles.
Shingles vs UK Roof Tiles: What British DIYers Should Know
Bitumen shingles are common on sheds, garden offices, summerhouses and extensions in the UK, but most British houses use concrete or clay tiles or natural slate. If you are re-roofing a house, check UK building regulations approval — a full re-roof is notifiable work, and the roof must meet thermal and structural standards. The National Federation of Roofing Contractors also publishes guidance on choosing competent roofers.
For a typical UK project — say, a 20 m² garden office roof — you would need about 7 bundles of shingles (20 ÷ 3.1 = 6.45, plus waste, rounded up). At £30–£55 per bundle from UK merchants, materials run £210–£385 before felt underlay, nails and ridge caps.
Typical UK Costs (2026)
| Item | Typical UK price |
|---|---|
| Bundle of bitumen shingles (3.1 m² coverage) | £30 – £55 |
| Breathable felt underlay (per roll, ~30 m²) | £35 – £70 |
| Shingle nails (per kg) | £8 – £14 |
| Ridge caps (per linear metre) | £4 – £8 |
| Professional shingle installation (per m², labour + materials) | £55 – £95 |
Storage and Handling Tips
- Keep bundles flat. Stacking them on edge or in heat can warp bitumen shingles, making them impossible to lay flat.
- Store in the shade. Bitumen softens in strong sun; lay shingles in cooler morning hours in summer.
- Do not stack too high. More than about 8–10 bundles in a stack compresses the bottom ones.
- Plan the lift. At 25–35 kg per bundle, carrying them up a ladder is the hardest part of the job — a roof ladder or hoist is worth it for anything above a shed.
- Keep one spare bundle. Future repairs need matching shingles, and dye lots change between production runs.
How to Check a Bundle Before You Buy
Not all bundles are equal, especially with own-brand or imported shingles. Before loading up the trolley, check three things on the packaging:
- Stated coverage in m². The honest figure for a standard bundle is 3.1 m². If a bundle claims much more, the shingles are probably thinner or the exposure assumes an unusually steep overlap.
- Weight. Heavier bundles generally mean thicker, longer-lasting shingles. A suspiciously light bundle of “architectural” shingles is a red flag.
- Fire rating and wind rating. In the UK, look for a Class B or better fire rating and a wind-uplift rating suited to your exposure zone — coastal and hilltop sites need the highest ratings.
Buy all bundles for one roof from the same batch or dye lot. Bitumen shingles vary slightly in colour between production runs, and a patchwork roof is visible from the street.
Frequently Asked Questions
How many shingles are in a bundle?
Typically 21–29 for three-tab shingles or 15–22 for architectural shingles. The exact number varies by manufacturer — what is standardised is coverage: one bundle covers 33⅓ sq ft (3.1 m²).
How many bundles do I need for 100 square feet?
Three bundles make one roofing square of 100 sq ft, before waste. Add 10–15% for cutting waste, so order 4 bundles to be safe for a simple 100 sq ft roof.
How much does a bundle of shingles weigh?
Between 23 and 36 kg depending on type — three-tab bundles are lighter (23–29 kg), architectural bundles heavier (27–36 kg). Check the packaging, as weight affects delivery and handling.
Can I buy individual shingles?
Most merchants sell by the bundle only, though some sell single shingles for repairs at a premium. For patch repairs, one spare bundle kept from the original job is ideal because colours match.
Are shingles suitable for UK houses?
They are widely used on outbuildings, extensions and garden rooms. For a main house re-roof, concrete tiles, clay tiles or slate are the UK norm, and building regulations apply — check with your local authority or an NFRC-registered roofer first.
How long do shingle roofs last?
Three-tab shingles typically last 15–20 years, architectural shingles 25–30 years, in UK conditions. Wind exposure, moss growth and installation quality all affect lifespan. If your project involves measuring up first, a home inspection before buying can also flag roof condition.
