Roof Cost Per Square Foot Calculator

Understanding Roof Cost Per Square Foot

The cost per square foot for roofing includes both materials and labor. Here's what affects pricing:

• Material choice is the biggest variable — from $3.50/sqft (3-tab shingles) to $22+/sqft (natural slate).
• Labor rates vary by 15-30% between regions, with West Coast and Northeast being most expensive.
• Roof complexity (hips, valleys, dormers) adds 10-30% to labor costs.
• Lifespan value: More expensive materials often cost less per year when factoring in their longer lifespan.
