If 1,400 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:

How many bundles of shingles do I need for 1,400 sq ft?

For 1,400 sq ft of roof surface you need 47 bundles of standard shingles (3 bundles per square) including 10% waste, or 49 bundles with 15% waste for a roof with hips and valleys. Heavier shingles packed 4 bundles per square need 62 bundles.

How many squares is 1,400 sq ft?

A roofing square is 100 sq ft, so 1,400 sq ft is 14 squares, or 15.4 squares once you add 10% for waste.

Is 1,400 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 1,400 sq ft is your footprint, multiply it by your pitch factor: at 6/12 the roof is 1,565 sq ft and needs 52 bundles.

How much do shingles for 1,400 sq ft cost?

At typical material prices, shingles for 1,400 sq ft of roof (with 10% waste) cost about $1,232–$1,848 for 3-tab shingles, $1,540–$2,464 for architectural shingles, $2,464–$3,850 for premium shingles. That is materials only; installation usually costs more than the shingles.
