How many bundles of shingles for a 12×16 shed roof?

Data checked October 2026

Short answer

A 12 × 16 ft shed with a 4/12 gable roof and 6-in overhangs has about 233 sq ft of roof — 2.3 squares. Order 8 bundles of architectural shingles, including 8% waste.

Shingles: 233 sq ft + 8% waste ÷ 32.8 sq ft per bundle = 8 bundles. That is under the 39-bundle bulk tier, so expect single-bundle prices.
Also on the list: 1 bundle of starter for 61 ft of eaves and rakes, 1 bundle of ridge cap for 17 ft of ridge, 1 roll of #15 felt, 7 pieces of drip edge and about 911 roofing nails (1 × 5-lb box for hand nailing).
Weight: 8 bundles come to about 613 lb, roughly 77 lb each — check your truck's payload before hauling them yourself.
Cost: about $654 in materials at October 2026 shelf prices, before tax.
4/12 is the lowest pitch that takes a single layer of underlayment, and it is easy to walk.
12×16 is a common storage shed or small workshop.

How this was worked out

With 6-in overhangs the roof covers 13 × 17 ft = 221 sq ft of plan. A 4/12 pitch multiplies that by √(1 + (4/12)²) = 1.0541, giving 233 sq ft. CertainTeed's waste table puts a 233 sq ft gable at 8%, so 233 × 1.08 ÷ 32.8 sq ft per bundle = 7.67, rounded up to 8 bundles.

As a hip roof the surface is the same, but the edges change: 60 ft of eaves and 38 ft of hips need 1 starter and 2 ridge-cap bundles, and the waste allowance rises from 8% to 17% — 9 bundles instead of 8.
