Replacing a roof is one of the most significant home improvement expenses a homeowner faces. The national average in 2025 sits around $9,500, but costs range widely — from $5,700 for a small ranch-style home with basic asphalt shingles to $16,000 or more for a larger or more complex roof.
Understanding what drives that range helps you evaluate whether a quote is reasonable — or whether you're being taken for a ride.
Cost by roofing material
Material is the single biggest cost variable. Here's what to expect per square (100 sq ft) for common options, including labor:
| Material | Cost per square | Lifespan |
|---|
| 3-tab asphalt shingles | $150–$250 | 15–25 years |
| Architectural asphalt shingles | $200–$350 | 25–30 years |
| Metal (standing seam) | $700–$1,400 | 40–70 years |
| Wood shake | $450–$900 | 25–35 years |
| Concrete tile | $400–$800 | 50+ years |
| Slate | $900–$2,000+ | 75–150 years |
Most homeowners opt for architectural asphalt shingles — they're significantly more durable than 3-tab at a modest price premium, and they're what most roofing contractors know best.
Cost by home size
A typical home has a roof that's 30–50% larger than the footprint due to pitch. Here's what most homeowners pay for architectural shingles:
| Home size (sq ft) | Estimated roof size | Typical total cost |
|---|
| 1,000–1,500 | 15–20 squares | $5,700–$8,500 |
| 1,500–2,500 | 20–30 squares | $8,000–$11,500 |
| 2,500–3,500 | 30–40 squares | $10,500–$14,500 |
| 3,500+ | 40+ squares | $13,500–$18,000+ |
What else affects the price?
Roof pitch. Steep roofs require more safety equipment and slower work. A roof steeper than 6:12 typically adds 20–40% to labor costs.
Number of layers being removed. If your current roof has two layers of shingles (common on older homes), removing both adds $1,000–$3,000 to the job. Most building codes limit roofs to two layers total.
Decking condition. If the plywood sheathing underneath is rotted or damaged, replacing it runs $70–$100 per sheet. Contractors may not know the extent of this until the old shingles are off, so build some contingency into your budget.
Flashing. Flashing around chimneys, skylights, and vents should be replaced or resealed during a roof replacement. This adds $200–$500 but prevents leaks.
Region. Labor costs vary significantly by location. Roofing in the Northeast and West Coast typically runs 20–30% higher than the national average; parts of the Southeast and Midwest tend to be 10–20% lower.
What should your quote include?
A detailed roofing quote should specify: the shingle brand and product line (not just "architectural shingles"), underlayment type, how many layers will be removed, what happens to decking replacement if needed and at what cost, warranty information on both materials and labor, and a cleanup/haul-away plan.
A vague quote that just says "tear off and replace" with a lump-sum price is a problem. You have no way to compare it to other quotes or know what you're actually getting.
Signs a quote is too low
A quote significantly below others usually means one of three things: the contractor plans to leave the second layer of shingles in place (a shortcut), they're using lower-grade materials than competitors, or they'll hit you with change orders mid-job. Always ask what the low quote specifically includes that the higher ones don't.
Insurance claims
If your roof damage is from a storm, hail, or wind, your homeowner's insurance may cover most of the replacement cost minus your deductible. Document the damage with photos before any work begins. Be wary of contractors who offer to cover your deductible — this is insurance fraud in most states and typically signals a contractor you don't want on your roof.
