How many bundles of shingles for a 2,000 square foot house?
A single-story house with a 2,000 square foot footprint (50 × 40 ft) and a 6/12 gable roof has about 2,442 square feet of roof, or 24.4 squares, once the overhangs and the slope are counted. That takes 81 bundles of architectural shingles with 10 percent waste, 3 rolls of underlayment, 2 bundles of ridge cap, and 20 pieces of drip edge. A steeper 8/12 roof needs 87 bundles; a low 4/12 roof needs 76.
Shingles for a 2,000 sq ft house by roof pitch
| Pitch | Roof area | Squares | Bundles (10% waste) | Underlayment rolls |
|---|---|---|---|---|
| 4/12 | 2,302 sq ft | 23.0 | 76 | 3 |
| 6/12 | 2,442 sq ft | 24.4 | 81 | 3 |
| 8/12 | 2,625 sq ft | 26.2 | 87 | 3 |
| 10/12 | 2,843 sq ft | 28.4 | 94 | 4 |
| 12/12 | 3,089 sq ft | 30.9 | 102 | 4 |
Gable roof on a 50 × 40 ft footprint with 12 in overhangs, three-bundle architectural shingles, and 10-square rolls of synthetic underlayment. A hip roof of the same footprint at 6/12 takes about 81 bundles because of extra cutting waste.

Why the pitch changes the count
The footprint is flat; the roof is not. A 6/12 pitch is 11.8 percent longer than the run it covers, so 2,184 square feet of footprint plus overhang becomes 2,442 square feet of shingles. At 12/12 the multiplier is 1.414 and the same house needs 3,089 square feet, or 21 more bundles. If you cannot measure the pitch, count the courses of existing shingles up one slope: each course is about 5.6 inches of exposure on architectural shingles. Two-story houses have the same roof as one-story houses of the same footprint; what matters is the footprint, not the living area.
What it costs to reshingle a 2,000 sq ft house
Architectural shingles run $35 to $50 a bundle, so the 81 bundles for this roof cost about $2,835 to $4,050. Underlayment, ridge cap, drip edge, ice-and-water shield at the eaves, starter strip, and 54 nails add roughly $977 to $1,709. Installed by a roofing contractor, including tear-off and disposal of the old layer, a 24 square roof typically prices at $10,988 to $17,093, with steep or cut-up roofs at the high end. Tear-off produces about 3.1 tons of debris per layer removed; one 20-yard dumpster usually handles it.
Common questions
How many squares is a 2,000 square foot house?
About 24.4 squares for a 6/12 gable roof with 12 in overhangs, or 26.2 squares at 8/12. A roofing square is 100 square feet of roof surface, and the footprint grows by the overhangs and the pitch multiplier.
How many bundles of shingles for a 2,000 sq ft roof?
81 bundles at 6/12 pitch with 10 percent waste, using three bundles per square. At 4/12 it is 76; at 10/12, 94. A hip roof needs about 15 percent waste instead of 10, roughly 81 bundles at 6/12.
How much does a new roof cost for a 2,000 sq ft house?
Roughly $10,988 to $17,093 installed for architectural shingles on a 24 square roof, including tear-off. Materials alone are about $3,812 to $5,759. Metal roofing runs two to three times the shingle price.
