Rooftally: Roofing Calculator

Enter the house size and the pitch. Rooftally lays the roof out flat like a sewing pattern, measures every piece and turns it into an order slip you can take to the supplier.

MEASURE FROM THE GROUND

• Measure the walls, not the roof. The overhang is added on its own.

• Gable, hip, shed and flat roofs, or enter a measured area.

• Pitch in x/12, degrees or percent. Drag the ridge on the side view and watch the pitch change.

• Feet and inches or metres.

THE ORDER SLIP

• Shingles in bundles, hip and ridge cap, starter strip, roofing nails, underlayment, drip edge, ice and water shield, ridge vent.

• Architectural and 3-tab shingles, metal panels and standing seam, concrete and clay tile, corrugated sheets, built-up roofing.

• Waste set by the roof: 10 % on simple roofs, 15 % with hips, 20 % with valleys. Change it any time.

• One spare bundle on request, because running short stops the job for a day.

COST AND QUOTES

• Your own prices per bundle, roll or square, plus crew price and tax.

• Got a roofer's quote? Enter it and see how far it is from the materials and labor estimate.

SAFETY WARNINGS STAY FREE

Pitch too low for the material, tile too heavy for ordinary framing, a roof too steep to walk without a harness. Rooftally says so on the screen, and these warnings are never behind a paywall.
