What Does a New Roof Actually Cost?
A roof replacement is one of the biggest home expenses you'll face—but also one of the most important investments. Here's what drives the price and how to budget.
Cost by Roofing Material
| Material | Cost per Sq Ft (Installed) | Lifespan | Best For |
|---|---|---|---|
| 3-tab asphalt shingles | $3.50–$5.50 | 15–20 years | Budget-conscious, simple roofs |
| Architectural shingles | $4.50–$7.00 | 25–30 years | Most homes (best value) |
| Metal (standing seam) | $8–$14 | 40–70 years | Longevity, energy efficiency |
| Metal (exposed fastener) | $5–$9 | 25–40 years | Budget metal option |
| Slate | $15–$30 | 75–100+ years | Historic homes, luxury |
| Tile (clay or concrete) | $10–$20 | 50–75 years | Mediterranean/Southwest style |
| Synthetic slate/shake | $8–$12 | 30–50 years | Slate look without the weight |
Cost by Home Size
| Home Size (Sq Ft) | Approximate Roof Area | Asphalt (Architectural) | Metal (Standing Seam) |
|---|---|---|---|
| 1,000–1,500 | 1,200–1,800 sq ft | $5,000–$10,000 | $10,000–$20,000 |
| 1,500–2,500 | 1,800–3,000 sq ft | $8,000–$16,000 | $15,000–$30,000 |
| 2,500–3,500 | 3,000–4,500 sq ft | $13,000–$22,000 | $25,000–$45,000 |
What's Included in a Roof Replacement
A quality roof replacement includes:
- Tear-off: Removing all existing shingles and underlayment
- Decking inspection: Checking for rot, water damage, and structural issues
- Ice and water shield: Applied along eaves and valleys
- Synthetic underlayment: Covers the entire roof deck
- Drip edge and flashing: Metal protection at edges, valleys, and penetrations
- Starter strip and shingles: The main roofing material
- Ridge cap and ventilation: Proper attic ventilation is critical for roof longevity
- Cleanup: Magnetic nail sweep and debris removal
What Drives Costs Up
Roof complexity: Hips, valleys, dormers, chimneys, and skylights increase labor and material costs. A complex roof can cost 30–50% more than a simple gable roof of the same size.
Decking repair: If the plywood beneath your shingles is rotted or damaged, replacement costs $50–$100 per sheet (4x8). Most roofs need 2–10 sheets replaced.
Steep pitch: Roofs steeper than 8/12 require specialized equipment and safety measures, adding 20–30% to labor costs.
Multiple layers: If your existing roof has two layers of shingles, tear-off costs double ($100–$150/square vs. $50–$75 for single layer).
Permits: Required in all municipalities, typically $100–$500.
The Value of a New Roof
A new roof returns 60–70% of its cost in home value according to Remodeling Magazine's Cost vs. Value Report. It's also one of the first things home inspectors and buyers notice—a roof in poor condition can kill a sale or reduce your price by $10,000–$20,000.
How to Save on a New Roof
- Get 3–5 estimates from licensed, insured roofers
- Schedule in late fall or winter — off-season rates save 5–15%
- Check for manufacturer rebates — GAF, Owens Corning, and CertainTeed run seasonal promotions
- Consider insurance — if storm damage is involved, your homeowner's policy may cover replacement minus deductible
- Ask about financing — many roofers offer 0% financing for 12–18 months
