Houses with a 3,000 square foot roof

A 3,000 square foot roof is a large house: a one-story of about 2,500 square feet, or a two-story of about 5,000. Roofs this size usually have several sections, with hips, valleys and a garage.

The ridge, drip edge and vent numbers below are for that one-story house: about 61 by 41 feet, under a 6 in 12 roof with 12 inch overhangs.

Shingle order for a 3,000 square foot roof

With 10 percent waste, architectural shingles at 3 bundles a square, #15 felt and 4 nails a shingle:

3,300 square feet with the waste is 33 squares, so 33 × 3 = 99 bundles, and 3,300 ÷ 400 = 8.25, rounded up to 9 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 99 bundles is 1 full pallet plus 43 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 104 bundles instead of 99.

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 132.

Underlayment and nails for 3,000 square feet

9 rolls of #15 felt ($315), 17 rolls of #30 felt ($595) or 4 rolls of synthetic ($364). From 2 in 12 up to 4 in 12, the code wants a double layer, about 17 rolls of #15 felt. Nails: about 8,448 at 4 a shingle, or 12,672 at 6 for high wind; three-tab takes 10,560 or 15,840.

Ridge cap and drip edge on a 3,000 square foot roof

These go by length, not area. On the 61 by 41 foot house above, a gable roof has one long ridge; a hip roof has a short ridge and four hips that need cap too.

Gable63 ftNone4$300221 ft
Hip20 ft128 ft8$600211 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 3,000 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 2,377 square inches over the 2,476 square foot house above. It is 1,189 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 3,000 square feet your roof or your floor?

This page is for 3,000 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 3,000 square feet of floor and a 6 in 12 roof, the roof is about 3,609 square feet and takes 120 bundles, 21 more than the list above. On a two-story house with 1,500 square feet a level, it is about 1,858 square feet and 62 bundles. The roof area calculator measures your own.

What a 3,000 square foot shingle roof costs

Shingles and felt come to about $4,769, or $4,571 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 $12,000 to $36,000 here, plus $3,000 to $15,000 for the tear-off. The 3,000 square foot roof cost page breaks that down.

The job at 3,000 square feet

At about 33 squares, a crew works through it over several days. The tear-off fills a large dumpster, and the shingles come on two pallets. Ask how many people the roofer will send; a bigger crew finishes sooner and leaves the roof open to weather for less time.

Before you order

On a roof this size, small prices add up. Ridge cap, drip edge, starter strip, vents and flashing are not in the shingle count, and they add up to a real share of the material bill. Use the ridge cap and drip edge numbers on this page as a start, then measure your own.

Other roof sizes

The next size down, 2,500 square feet, takes 83 bundles. The next size up, 3,500 square feet, takes 116 bundles.
