Houses with a 2,000 square foot roof
A 2,000 square foot roof sits on a one-story house of about 1,600 square feet or a two-story house of about 3,200. It is close to the middle of the sizes most roofers see on houses.
The ridge, drip edge and vent numbers below are for that one-story house: about 49 by 33 feet, under a 6 in 12 roof with 12 inch overhangs.
Shingle order for a 2,000 square foot roof
With 10 percent waste, architectural shingles at 3 bundles a square, #15 felt and 4 nails a shingle:
| Item | Quantity | Cost |
|---|---|---|
| Shingle bundles, architectural | 66 | $2,969 |
| Squares | 20 on the roof, 22 to order | |
| Underlayment, #15 felt | 6 rolls | $210 |
| Roofing nails | About 5,632 | Not priced |
| Total | About $3,179 |
2,200 square feet with the waste is 22 squares, so 22 × 3 = 66 bundles, and 2,200 ÷ 400 = 5.5, rounded up to 6 rolls of felt. Prices: $44.99 a bundle and $34.99 a roll. The starting prices come from the store listings and cost guides under Sources, last checked in October 2026. Prices vary by region and season, so change any price to match your store or your quote.
IKO packs its Cambridge architectural shingles 56 bundles to a pallet, so 66 bundles is 1 full pallet plus 10 bundles. Other makers pack differently.
How waste and shingle type change the order
Ten percent waste suits a simple gable roof. With hips and valleys, plan on about 15 percent, which makes this order 69 bundles instead of 66.
| Waste | Squares to order | Bundles | Architectural shingles | Three-tab shingles |
|---|---|---|---|---|
| None | 20 | 60 | $2,699 | $2,579 |
| 10%, simple gable roof | 22 | 66 | $2,969 | $2,837 |
| 15%, hips and valleys | 23 | 69 | $3,104 | $2,966 |
Three-tab shingles also come 3 bundles to a square, so the count holds and only the price changes. Shingles packed 4 bundles to a square would take 88.
Underlayment and nails for 2,000 square feet
6 rolls of #15 felt ($210), 11 rolls of #30 felt ($385) or 3 rolls of synthetic ($273). From 2 in 12 up to 4 in 12, the code wants a double layer, about 11 rolls of #15 felt. Nails: about 5,632 at 4 a shingle, or 8,448 at 6 for high wind; three-tab takes 7,040 or 10,560.
Ridge cap and drip edge on a 2,000 square foot roof
These go by length, not area. On the 49 by 33 foot house above, a gable roof has one long ridge; a hip roof has a short ridge and four hips that need cap too.
| Roof shape | Ridge | Hips | Cap bundles, 20 ft each | Cap cost | Drip edge |
|---|---|---|---|---|---|
| Gable | 51 ft | None | 3 | $225 | 181 ft |
| Hip | 16 ft | 105 ft | 7 | $525 | 172 ft |
Cap is $74.99 a bundle. The code wants drip edge on every eave and rake, lapped 2 inches, so buy a little extra.
Attic vents under 2,000 square feet of roof
The code sizes attic vents by the floor under them: 1 square foot of open vent for every 150 of attic, which is 1,556 square inches over the 1,621 square foot house above. It is 778 if 40 to 50 percent of the vents sit within 3 feet of the ridge and the rest low, plus a ceiling vapor retarder in climate zones 6 to 8. Check the net free area printed on each vent's box.
Is 2,000 square feet your roof or your floor?
This page is for 2,000 square feet of sloped roof. A roof is bigger than the floor under it, so the table works both ways.
| Roof pitch | Ground a 2,000 sq ft roof covers | Roof over a 2,000 sq ft floor | Bundles for that roof |
|---|---|---|---|
| 4 in 12 | 1,897 sq ft | 2,305 sq ft | 77 |
| 6 in 12 | 1,789 sq ft | 2,445 sq ft | 81 |
| 8 in 12 | 1,664 sq ft | 2,628 sq ft | 87 |
| 10 in 12 | 1,536 sq ft | 2,846 sq ft | 94 |
| 12 in 12 | 1,414 sq ft | 3,092 sq ft | 103 |
The floor column is a one-story house one and a half times as long as it is wide, with 12 inch overhangs. With 2,000 square feet of floor and a 6 in 12 roof, the roof is about 2,445 square feet and takes 81 bundles, 15 more than the list above. On a two-story house with 1,000 square feet a level, it is about 1,267 square feet and 42 bundles. The roof area calculator measures your own.
What a 2,000 square foot shingle roof costs
Shingles and felt come to about $3,179, or $3,047 with three-tab, before nails, cap, drip edge, flashing, vents, delivery and tax. Installed, HomeAdvisor puts an asphalt shingle roof at $4 to $12 per square foot, which is $8,000 to $24,000 here, plus $2,000 to $10,000 for the tear-off. The 2,000 square foot roof cost page breaks that down.
The job at 2,000 square feet
HomeAdvisor says a roofing crew can usually do a medium-sized shingle roof in two to three days, and 20 squares is about that size. The first day is usually the tear-off and the underlayment; the shingles, ridge and flashing follow. Steep pitches, chimneys and skylights make it longer.
Before you order
A three-day job needs three dry days. Ask the roofer what they do if rain is coming partway through: the usual answer is to tear off only as much as they can cover with underlayment the same day.
Other roof sizes
The next size down, 1,800 square feet, takes 60 bundles. The next size up, 2,200 square feet, takes 73 bundles.
