# Roofing Cost Calculator Tacoma WA | Tacoma Roofing > Free roofing cost calculator built on Tacoma-specific pricing by material. URL: https://tacomaroofing.net/tools/roofing-cost-calculator/ ## Material pricing (per roofing square, 100 sq ft, installed) - Asphalt / architectural shingle: $420-$1040 - Flat / low-slope (TPO, single-ply): $835-$2080 - Standing seam / metal: $1040-$2600 ## What moves the price - Tear off and dispose of the existing roof, per square: $40-$100 per square - Replace damaged roof deck sheathing, per sheet (if needed — not every job): $75-$150 per sheet This is a budgeting estimate, not a quote. It's built from Valentine Roofing's Tacoma-specific, material-broken-out published pricing — a real local contractor's own numbers, not a blended city-wide average — so treat it as a solid starting range, not a precise number. Your actual price depends on your roof's specific size, pitch, number of penetrations, material, storm/age-driven deck damage, and access. A binding number comes from a free on-site inspection.
