Shingle bundles for 2,200 sq ft of roof
These counts are for 2,200 sq ft of actual roof surface, measured on the slope. Most architectural and 3-tab shingles come three bundles to a square (100 sq ft); some heavier premium shingles take four. Suppliers sell whole bundles, so each count is rounded up.
| Waste allowance | Squares to order | Bundles (3 a square) | Bundles (4 a square) |
|---|---|---|---|
| None (exact) | 22.0 | 66 | 88 |
| 10% (simple gable) | 24.2 | 73 | 97 |
| 15% (hip, valleys) | 25.3 | 76 | 102 |
| 20% (complex roof) | 26.4 | 80 | 106 |
You will also need about 3 rolls of synthetic underlayment (1,000 sq ft rolls with 10% for laps), plus starter strip along the eaves and rakes and ridge cap along the ridges and hips.
If 2,200 sq ft is the house footprint
Many people know the floor area of the house, not the roof. A roof covers the footprint plus the overhang, and the slope makes it larger again. For a 55 × 40 ft house (2,200 sq ft) with a 1 ft overhang, the roof covers 2,394 sq ft in plan, and the table shows how the pitch adds to that. Bundles include 10% waste, at three a square.
| Roof pitch | Roof area (sq ft) | Squares | Bundles |
|---|---|---|---|
| 4/12 | 2,523 | 25.2 | 84 |
| 6/12 | 2,677 | 26.8 | 89 |
| 8/12 | 2,877 | 28.8 | 95 |
| 10/12 | 3,116 | 31.2 | 103 |
| 12/12 | 3,386 | 33.9 | 112 |

Weight, nails and edge metal
Architectural shingles weigh about 60 to 80 lb a bundle, so 73 bundles are roughly 5,110 lb (2.6 tons) to lift onto the roof, which is the hard part of the job. Spread bundles across the roof's rafters, never stacked in one spot.
At about 320 nails a square (four per shingle), a 22.0 square roof uses around 7,040 nails, which is a 25 lb box or a couple of coils for a nail gun. Drip edge runs along the eaves and up the rakes: measure those edges and divide by 10 for the number of 10 ft pieces.
A 2,200 sq ft roof: about 2.2 to 2.9 tons on the driveway
2,200 sq ft of roof is 22.0 squares, so 66 bundles without waste and 73 with 10%. At 60 to 80 lb a bundle the delivery weighs 4,380 to 5,840 lb, which is 2.2 to 2.9 tons, and it arrives on pallets.
Decide where the pallets go before the truck comes. They need firm, level ground that the delivery driver can reach, and they should not block the spot where the dumpster for the old roof has to stand. Keep the bundles flat, dry and out of strong sun until they are used, since shingles stored on edge or left to heat up in their wrappers can stick together or take a curve.
How much bigger the roof is than the floor
The 55 × 40 ft example house has 2,200 sq ft of floor, and the roofing calculator in footprint mode gives it 2,677 sq ft of roof at a 6/12 pitch with a 1 ft overhang. That is 1.22 times the floor area, or 22% more.
Two things make the difference. The overhang widens the roof to 57 × 42 ft in plan, which is 2,394 sq ft, and the slope then stretches every foot of run to 1.118 ft. Multiply the two and you have the roof. For a quick check on any simple gable house, work out the plan area with the overhang and multiply by the slope factor for your pitch.

How many bundles of shingles do I need for 2,200 square feet?
2,200 square feet of roof is 22 squares. At three bundles a square that is 66 bundles exactly, so buy 73 bundles with 10% for waste on a simple gable roof, or 76 with 15% for a hip roof or one with valleys.
How many squares is 2,200 square feet of roof?
22 squares, because one roofing square is 100 square feet. With 10% waste you order 24.2 squares, which suppliers round to whole bundles: 73.
What if 2,200 sq ft is the size of my house, not the roof?
Then the roof is bigger, because it slopes and overhangs the walls. A 55 × 40 ft house (2,200 sq ft) with a 1 ft overhang and a 6/12 pitch has about 2,677 sq ft of roof, which is 26.8 squares and 89 bundles with 10% waste.
