A new roof is one of the biggest repair bills a homeowner faces. The final price depends on roof size, pitch, material, how many old layers come off, and local labor rates. This guide gives you 2026 roof replacement costs from major US cost guides, compares the main roof types (asphalt shingle, metal, tile and slate) on cost, lifespan and weight, and shows how to measure your roof and read a quote.
Quick answer: the average roof replacement in the US is around $9,500 (Angi data), and many asphalt shingle jobs on typical homes fall roughly between $6,000 and $15,000. Metal, tile and slate roofs can cost $15,000 to $40,000+.
Roof replacement cost by material (2026)
| Material | Installed cost per sq ft of roof | Typical lifespan | Approx. weight |
|---|---|---|---|
| Asphalt shingles (3-tab) | About $3 – $6 | 15 – 20 years | Light (about 2–3 lb/sq ft) |
| Architectural asphalt shingles | About $5 – $8.50 | 25 – 30 years | Light (about 3–4.5 lb/sq ft) |
| Metal (exposed fastener to standing seam) | About $9 – $18 (standing seam can be higher) | 40 – 70 years | Very light (about 1–1.5 lb/sq ft) |
| Clay or concrete tile | About $12 – $25+ | 50+ years | Heavy (about 9–12 lb/sq ft) |
| Natural slate | About $12 – $30 | 75 – 100+ years | Heavy (about 8–15 lb/sq ft) |
How to estimate your roof area
Your roof is bigger than your floor plan because it is sloped and has overhangs. Roofers price in “squares”: 1 square = 100 sq ft of roof.
- Take the house footprint including overhangs (length × width).
- Multiply by the pitch factor from the table below.
- Add about 10–15% waste for cutting, hips and valleys.
| Roof pitch (rise/run) | Pitch factor |
|---|---|
| 4/12 | 1.054 |
| 6/12 | 1.118 |
| 8/12 | 1.202 |
| 10/12 | 1.302 |
| 12/12 | 1.414 |
Example: footprint with overhangs 50 ft × 32 ft = 1,600 sq ft. Pitch 6/12: 1,600 × 1.118 = 1,789 sq ft. Add 10% = about 1,970 sq ft, or about 20 squares. With architectural shingles at $5 – $8.50/sq ft, the estimate is about $9,800 – $16,700.
What a roof quote should include
- Tear-off and disposal of old roofing (and how many layers).
- Deck repair: price per sheet for replacing rotten plywood/OSB, since nobody knows the condition until tear-off.
- Underlayment (synthetic) and ice and water shield at eaves and valleys in cold climates.
- Flashing at chimneys, walls and skylights, and drip edge.
- Ventilation: ridge vents and intake vents. Poor ventilation shortens shingle life.
- Permit, cleanup, and both the manufacturer warranty and workmanship warranty.
Engineering check: can your roof carry a heavier material?
Switching from asphalt to tile or slate can add several pounds per square foot of permanent (dead) load. Many houses framed for shingles were not designed for that. Before you choose tile or slate, ask a structural engineer to check the rafters or trusses, the roof deck and the connections. Changing from shingles to metal usually reduces the load.
Also consider climate: heavy snow areas need the roof to carry snow loads; high-wind and hurricane areas need special fastening and rated materials.
Signs you need a new roof
- Shingles curling, cracking or missing in many places.
- Lots of granules in the gutters.
- Daylight or water stains in the attic.
- A sagging roof line (this is structural; call an engineer).
- The roof is near the end of the material’s normal lifespan.
Ways to save money
- Get at least three quotes with the same scope (material, underlayment, ventilation).
- Book in the off-season if your area has one.
- Check if storm damage is covered by your homeowners insurance before paying yourself.
- Compare cost per year of life: a roof that costs 50% more but lasts twice as long is cheaper over time.
Frequently asked questions
How long does a roof replacement take?
An average asphalt shingle roof on a single-family house often takes 1–3 days. Tile, slate and complex roofs take longer.
Can new shingles go over old ones?
Codes often allow one overlay layer in some cases, but a full tear-off lets the roofer inspect and repair the deck, and usually gives a longer-lasting roof.
Is a metal roof worth it?
If you plan to stay long-term, often yes: it lasts much longer than asphalt, is light, and handles snow and fire well. The upfront cost is higher.
