How Many Bundles of Shingles for 500 sq ft?

500 sq ft of roof surface is 5 roofing squares. With 10% waste and standard 3-bundle-per-square shingles you need 17 bundles. If 500 sq ft is the house footprint rather than the roof, multiply by the pitch factor first: at a 6/12 pitch that becomes 19 bundles.

If 500 sq ft is the house footprint

Shingles cover the sloped roof, not the floor plan. Multiply the footprint (including overhangs) by the pitch factor to get roof surface:

Frequently asked questions

How many bundles of shingles do I need for 500 sq ft?

For 500 sq ft of roof surface you need 17 bundles of standard shingles (3 bundles per square) including 10% waste, or 18 bundles with 15% waste for a roof with hips and valleys. Heavier shingles packed 4 bundles per square need 22 bundles.

How many squares is 500 sq ft?

A roofing square is 100 sq ft, so 500 sq ft is 5 squares, or 5.5 squares once you add 10% for waste.

Is 500 sq ft the house size or the roof size?

Shingles are ordered by roof surface, which is larger than the house footprint because of the slope and overhangs. If 500 sq ft is your footprint, multiply it by your pitch factor: at 6/12 the roof is 559 sq ft and needs 19 bundles.

How much do shingles for 500 sq ft cost?

At typical material prices, shingles for 500 sq ft of roof (with 10% waste) cost about $440–$660 for 3-tab shingles, $550–$880 for architectural shingles, $880–$1,375 for premium shingles. That is materials only; installation usually costs more than the shingles.
