Before you start
The calculator works out your roof's surface area first, then multiplies it by a cost per square foot. It divides your home's living area by the number of stories to get the footprint. It then multiplies that footprint by a slope factor, 1.12 for a walkable roof or 1.30 for a steep one, and by 1.10 for the overhang at the eaves.
The rates come from cost rows in our roof replacement cost guide: RoofVista's 2026 Allen figures of $4.24–$6.36 per sq ft for architectural shingles, $5.40–$8.64 for Class 4 shingles and $8.40–$14.70 for metal. The shingle rate here, $4.50 to $7.00, stretches from architectural shingles up through most Class 4 jobs. The metal rate, $8.50 to $12.50, starts near RoofVista's floor and leaves headroom for standing seam and tear-off.
A rough home size is all you need. The square footage on your listing or tax record will do.
