Houses with a 1,000 square foot roof

A 1,000 square foot roof is small. It is the roof of a detached two-car garage, a cabin or cottage, a small older house, or a single wing or addition on a bigger one.

The ridge, drip edge and vent numbers below are for that one-story house: about 34 by 23 feet, under a 6 in 12 roof with 12 inch overhangs.

1,100 square feet with the waste is 11 squares, so 11 × 3 = 33 bundles, and 1,100 ÷ 400 = 2.75, rounded up to 3 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 33 bundles is less than one full pallet. 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 35 bundles instead of 33.

15%, hips and valleys11.535$1,575$1,505

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 44.

Underlayment and nails for 1,000 square feet

3 rolls of #15 felt ($105), 6 rolls of #30 felt ($210) or 2 rolls of synthetic ($182). From 2 in 12 up to 4 in 12, the code wants a double layer, about 6 rolls of #15 felt. Nails: about 2,816 at 4 a shingle, or 4,224 at 6 for high wind; three-tab takes 3,520 or 5,280.

Ridge cap and drip edge on a 1,000 square foot roof

These go by length, not area. On the 34 by 23 foot house above, a gable roof has one long ridge; a hip roof has a short ridge and four hips that need cap too.

Gable36 ftNone2$150128 ft
Hip11 ft74 ft5$375122 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 1,000 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 746 square inches over the 777 square foot house above. It is 373 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 1,000 square feet your roof or your floor?

This page is for 1,000 square feet of sloped roof. A roof is bigger than the floor under it, so the table works both ways.

The floor column is a one-story house one and a half times as long as it is wide, with 12 inch overhangs. With 1,000 square feet of floor and a 6 in 12 roof, the roof is about 1,267 square feet and takes 42 bundles, 9 more than the list above. On a two-story house with 500 square feet a level, it is about 666 square feet and 22 bundles. The roof area calculator measures your own.

What a 1,000 square foot shingle roof costs

Shingles and felt come to about $1,590, or $1,524 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 $4,000 to $12,000 here, plus $1,000 to $5,000 for the tear-off. The 1,000 square foot roof cost page breaks that down.

The job at 1,000 square feet

At 10 squares, this is a roof one experienced person and a helper can shingle themselves, and that a roofing crew often finishes in a day. All of the bundles fit on less than one pallet, so the store can drop them in the driveway and you can carry them up as you go.

Before you order

Buy one or two more bundles than the roof needs, from the same batch. Shingle colors shift a little between production runs, so spares bought later for a repair may not match. On a small roof, a single leftover bundle covers most patch jobs for years.

Other roof sizes

The next size up, 1,200 square feet, takes 40 bundles.
