How much does a new roof replacement cost on average?

Most homeowners pay between $5,500 and $12,500 for a full roof replacement on an average 2,000 sq ft home using architectural asphalt shingles. Premium materials such as standing seam metal, clay tile, or natural slate range from $15,000 to $45,000+ depending on pitch and structure.

How much does old roof tear-off and disposal cost?

Tearing off and disposing of a single layer of existing asphalt shingles typically costs between $1.00 and $2.00 per square foot ($100 to $200 per roofing square). Multiple existing layers or heavy materials like wood shakes or tiles cost more to remove.

How does roof pitch affect replacement costs?

Roofs with steep slopes (8:12 and higher) require safety harnesses, scaffolding, and extra staging, which slows down installation time. Contractors apply steep-slope labor surcharges of 15% to 35% on high-pitched roofs.

What is included in a complete roof replacement estimate?

A comprehensive estimate includes old roof tear-off and disposal dumpster fees, new synthetic underlayment, ice and water shield in valleys and eaves, starter strips, primary roofing material, drip edges, ridge vents, ridge cap shingles, flashing around chimneys/pipes, contractor labor, and manufacturer warranties.

Understanding Roof Replacement Costs

Roof replacement bids depend on roof geometric surface area (measured in roofing squares of 100 sq ft), pitch steepness, material durability, and whether existing layers must be torn off down to the deck.

1. Roofing Squares: Total Sloped Square Footage ÷ 100

2. Materials Cost: Base Square Rate × Roofing Squares × 1.10 (Waste Margin)

3. Labor Cost: Base Labor × Roofing Squares × Pitch Multiplier × Location Index

4. Tear-Off & Disposal: Removal Rate ($1.00–$3.00/sq ft) × Total Surface Area

5. Total Estimate: Materials + Labor + Tear-off & Disposal + Flashing/Permits
