# Roofing Cost Calculator Everett WA | Roofing Everett WA > Free roofing cost calculator built on pricing reconciled for the Everett/Snohomish County area. URL: https://roofingeverettwa.com/tools/roofing-cost-calculator/ ## Material pricing (per roofing square, 100 sq ft, installed) - Asphalt / composition shingle: $450-$900 - Cedar shake: $800-$1600 - Flat / low-slope (TPO, EPDM): $1250-$2700 - Standing seam / metal: $1550-$3400 ## 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 reconciles multiple published data sets for the Everett/Snohomish County market — Everett-specific aggregator data and a WA-wide contractor-published total-job range — which don't fully agree with each other, so treat this as the middle of a real range, not a precise number. Your actual price depends on your roof's specific size, pitch, number of penetrations, material, wind/age-driven deck damage, and access. A binding number comes from a free on-site inspection.
