How Many Bundles of Shingles for 1,000 Square Feet? (2026)

For a 1,000-square-foot roof, you need 30 bundles of shingles before waste, and 33 bundles with a standard 10 percent waste allowance. On a cut-up roof with dormers, valleys, and hips, use 15 to 20 percent waste instead, which brings the order to 36 bundles. The math is simple: 1,000 square feet equals 10 roofing squares, and at the standard 3 bundles per square, 10 times 3 is 30 — waste is the only part people forget, and it is the part that causes mid-job shortages.

That 1,000-square-foot figure is roof surface area, not house footprint. If your 1,000 square feet is the footprint of the house, the roof surface is larger once pitch is factored in — see the pitch section below, or run your numbers through our shingle bundle calculator to get the count for your exact roof.

The Bundle Math, Step by Step

Roofers work in squares: one square is 100 square feet of roof surface. Standard asphalt bundles cover 33.3 square feet each, so 3 bundles make a square. The formula for any roof is: roof area divided by 100 gives squares, squares times 3 gives base bundles, and base bundles times 1.10 gives the order quantity for a straightforward roof. For 1,000 square feet: 10 squares, 30 base bundles, 33 bundles ordered.

Waste is not a fudge factor. Starter courses along the eaves, cuts at valleys and hips, trimming around dormers, vents, and chimneys, and the occasional damaged shingle all consume material that never appears as finished coverage. A simple gable roof wastes about 10 percent. A cut-up roof with multiple valleys and dormers wastes 15 to 20 percent. Ordering the waste up front costs a few bundles; running short costs a delivery fee, a crew standing idle, and a color-lot mismatch if the second batch comes from a different production run.

Bundle Counts for Common Roof Sizes

The table below covers the three roof sizes homeowners ask about most, at the standard 3 bundles per square. If your shingles are a 25-square-foot architectural line (4 bundles per square), multiply the base bundle column by 4 over 3 — a 1,000-square-foot roof would need 40 base bundles instead of 30.

Roof surface area	Squares	Base bundles	Order quantity (10% waste)	Cut-up roof (15–20% waste)
1,000 sq ft	10	30	33	35–36
1,500 sq ft	15	45	50	52–54
2,000 sq ft	20	60	66	69–72

Read the 1,500 and 2,000 rows as the same formula scaled up, not as separate rules: 15 squares times 3 is 45, plus 10 percent is 49.5, rounded up to 50. Twenty squares times 3 is 60, plus 10 percent is 66 exactly. Rounding always goes up — a half bundle cannot be ordered, and the spare becomes repair stock. For the underlying coverage figure behind these numbers, see our guide to how many square feet are in a bundle of shingles.

Footprint Versus Roof Area: Why Your 1,000 Square Feet Might Not Be 1,000

This is where most bundle estimates go wrong. A house with a 1,000-square-foot footprint does not have a 1,000-square-foot roof, because the roof slopes add surface. The steeper the pitch, the bigger the difference: a low 4/12 pitch adds about 6 percent, a common 6/12 pitch adds about 12 percent, and a steep 12/12 pitch adds about 41 percent. So a 1,000-square-foot footprint under a 6/12 roof is really about 1,120 square feet of roof surface — 11.2 squares, 34 base bundles, 37 ordered — not 33.

To convert properly, measure each roof slope (length times slope width) and add them, or use our roof pitch calculator to turn footprint and pitch into true roof area. The few minutes that conversion takes are worth more than any other step in this guide, because every number downstream — squares, bundles, waste, and the quote itself — inherits its error if the area is wrong.

What Else to Order Besides Field Bundles

Field bundles are not the whole order. Starter strip shingles run along every eave and rake edge, hip and ridge cap shingles cover every ridge and hip (ordered by linear foot, not by area), and underlayment, ice-and-water shield, drip edge, and flashing complete the system. On a 1,000-square-foot roof, forgetting the ridge cap alone can stall the finish day, since cap shingles are a different product from field shingles and are not interchangeable with them.

Brand matching matters too. Shingle colors vary slightly between production lots, so order the full quantity — field bundles, starter, and caps — from the same supplier at the same time, and keep one or two unopened bundles in the garage for future repairs. A repair done with a different lot can read as a visible patch from the street. Our GAF shingles guide covers the brand most Lake County crews stock, if you want to confirm availability before the order goes in.

Checking a Contractor’s Bundle Count

Use the formula above to sanity-check any bid — or run your roof through our shingle bundle calculator and compare its output against the bid. A contractor quoting 40 bundles for a straightforward 1,000-square-foot roof is either measuring a larger roof than you think, working with a 25-square-foot bundle product, or padding the order — ask which. A contractor quoting exactly 30 bundles with no waste allowance is planning to run short or planning a second delivery at your expense. The credible range for a standard 1,000-square-foot roof is 33 bundles for a simple roof and up to 36 for a cut-up one, and a bid inside that range with the waste line itemized is a bid you can trust.

Frequently Asked Questions

How many bundles of shingles do I need for 1,000 square feet?

For a 1,000-square-foot roof surface, you need 30 bundles before waste and 33 bundles with a standard 10 percent waste allowance. On a cut-up roof with dormers, valleys, and hips, use 15 to 20 percent waste, which brings the order to 35 to 36 bundles. The math is 10 roofing squares times 3 bundles per square, plus waste.

How many bundles of shingles for 1,500 square feet?

A 1,500-square-foot roof is 15 squares, which needs 45 bundles before waste and 50 bundles with a 10 percent waste allowance (49.5 rounded up). On a cut-up roof at 15 to 20 percent waste, order 52 to 54 bundles. If your shingles are a 25-square-foot architectural line at 4 bundles per square, the base count rises to 60 bundles before waste.

How many bundles of shingles for 2,000 square feet?

A 2,000-square-foot roof is 20 squares, which needs 60 bundles before waste and 66 bundles with a 10 percent waste allowance. On a cut-up roof at 15 to 20 percent waste, order 69 to 72 bundles. Always round up, since a partial bundle cannot be ordered and the spare becomes matched repair stock.

Is 1,000 square feet the footprint or the roof area?

Bundle math uses roof surface area, not house footprint. A 1,000-square-foot footprint under a common 6/12 pitch is about 1,120 square feet of roof surface, which needs 34 base bundles and 37 ordered, not 33. A steep 12/12 pitch adds about 41 percent. Measure the slopes or convert footprint and pitch with a roof pitch calculator before ordering.

How much waste should I add to a shingle order?

Add 10 percent waste for a straightforward gable or hip roof, and 15 to 20 percent for a cut-up roof with dormers, valleys, and hips. Waste covers starter courses, cuts at valleys and hips, trimming around vents and chimneys, and damaged pieces. Ordering waste up front avoids a second delivery fee, crew downtime, and a color-lot mismatch on the second batch.
