So funktioniert’s

Pitch factor = √(1 + (rise÷12)²). Roof area = plan area × factor. Squares = area ÷ 100 × (1 + waste%). Bundles = ceil(squares × bundles per square).

Rechenbeispiel

Example: 2,000 sq ft plan area, pitch factor 1.12, 10% waste, 3 bundles/square → about 24.6 squares and 74 bundles.

What is a square?

One roofing square = 100 sq ft of roof surface. Suppliers price many shingles by the square or by the bundle.

Pitch factor

Steeper roofs have more surface than the building footprint. Common factors range about 1.05–1.3—use a pitch chart or measure slope.

Bundles per square

Three bundles per square is common for architectural shingles, but always check the wrapper.

Häufige Fragen

How many shingle bundles do I need?

Convert roof area to squares with pitch and waste, then multiply by bundles per square. This calculator performs those steps.

What pitch factor should I use?

Look up your roof pitch (e.g. 6/12) on a surface-area factor chart, or have a roofer measure. Do not guess on complex roofs.

Does this include underlayment?

No—only shingle squares/bundles. Underlayment and ridge cap are separate takeoffs.
