How Much Does Roof Replacement Cost?
The average roof replacement costs $8,000-$15,000 for asphalt shingles on a typical single-story home. Metal roofing runs $12,000-$25,000. Tile and slate roofs cost $20,000-$45,000 or more. The total cost depends on roof size measured in squares (100 sq ft each), material choice, roof pitch and complexity, and your geographic location. Steep or complex roofs with multiple valleys and dormers cost 20-50% more due to additional labor and safety requirements.
Roofing Material Options Compared
Asphalt shingles are the most popular choice offering good value at $3-7 per square foot installed with a 20-30 year lifespan. Architectural shingles cost slightly more but look better and last longer than 3-tab shingles. Metal roofing costs $7-14 per square foot but lasts 40-70 years and reflects heat reducing cooling costs. Clay and concrete tiles cost $10-20 per square foot and last 50-100 years, ideal for warm climates. Slate is the premium option at $15-30 per square foot with a 75-150 year lifespan. Consider long-term value not just upfront cost when choosing materials.
Roof Replacement Signs and Tips
Replace your roof when you see curling or missing shingles, granules in gutters, daylight through the roof deck, or the roof is over 20 years old. Get at least three written estimates from licensed, insured contractors. Check if your homeowner insurance covers storm damage. Many contractors offer financing options for major roof replacements. Time your project during the shoulder seasons for better pricing and availability. A new roof can recoup 60-70% of its cost at resale and is often required for home sales and insurance renewals.
