Formula & assumptions

How the shingle calculator works

Order area = roof area × (1 + waste %). Roofing squares = order area ÷ 100. Bundles = order area ÷ coverage per bundle. Approximate shingles = bundles × shingles per bundle.

For a better estimate

Use roof surface area after accounting for pitch, not building footprint alone.
Check the manufacturer label because bundle coverage and shingle count can vary by product.
Order strategy may need to account for starter strips, ridge caps and matching material for future repairs.

Common questions

Frequently asked questions

How many bundles of shingles do I need?+

Divide roof area including waste by the stated coverage per bundle, then round up to whole bundles.

How many bundles are in a roofing square?+

Many products are packaged at roughly three bundles per square, but coverage varies, so use the product label rather than assuming.

Do I need extra shingles for waste?+

Usually yes. Cuts, valleys, hips, starter details and roof complexity can increase waste beyond the net roof area.
