Based on published installed prices of $4–$10 per sq ft for asphalt shingles. Roof surface is estimated from footprint and slope. Removal of multiple old layers, rotten decking and local labor rates can raise the price.
Cost by roofing material
| Material | Per sq ft installed | 1,200 sq ft home* | 1,800 sq ft home* | 2,500 sq ft home* |
|---|---|---|---|---|
| Asphalt shingles | $4–$10 | $6,000–$15,000 | $9,000–$22,500 | $12,500–$31,300 |
| Metal (exposed fastener or shingle) | $7–$15 | $10,500–$22,500 | $15,800–$33,800 | $21,900–$46,900 |
| Standing seam metal | $10–$18 | $15,000–$27,000 | $22,500–$40,500 | $31,300–$56,300 |
| Tile or slate | $10–$25 | $15,000–$37,500 | $22,500–$56,300 | $31,300–$78,100 |
*Footprint with a medium-slope roof (about 25% more roof surface than footprint). Your roof's shape and local prices change the total.
Ways to lower the cost
- Get at least three written quotes that list tear-off, decking, underlayment and ventilation separately.
- Schedule outside the busy season; late fall and early spring often have more availability.
- Check whether storm damage makes part of the cost an insurance claim.
- Check each quote with the roof quote checker.
Roof replacement questions
How much does a new roof cost?
It depends mainly on roof size and material. Installed asphalt shingles typically cost $4–$10 per square foot of roof, metal $7–$15, standing seam $10–$18 and tile or slate $10–$25. Use the estimator above for your home's size and slope.
What is a roofing square?
Roofers measure in squares: one square is 100 square feet of roof surface. A roof is always larger than the home's footprint because of slope and overhangs.
What can make a new roof cost more than the estimate?
Removing more than one old layer, replacing rotten decking, steep or complex roofs, adding ventilation, and local labor prices. Ask each roofer to list these separately in the quote.
Is it cheaper to repair or replace my roof?
A single leak on a roof under about 15–20 years old is usually cheaper to repair. Replacement makes sense with widespread shingle wear, multiple leaks or soft decking, and for insurance and resale.
