Key Cost Drivers in Roof Replacement
Material choice changes the installed cost and expected service life. 3-tab asphalt is usually the budget option, architectural asphalt is the common middle tier, and standing seam metal is a premium long-life system.
Pitch increases actual roof surface area and can slow production when crews need additional fall-protection setup.
| Material | Average Installed Cost | Typical Lifespan |
|---|---|---|
| Basic 3-tab asphalt | $4 - $6 per sq. ft. | 15 - 25 years |
| Architectural asphalt | $4.50 - $8 per sq. ft. | 20 - 30 years |
| Standing seam metal | $8 - $14 per sq. ft. | 40 - 70 years |
| Natural slate | $15 - $30 per sq. ft. | 60 - 100+ years |
Professional Guidelines for Reviewing Contractor Bids
- Confirm tear-off, dumpster, driveway protection, and daily clean-up responsibilities.
- Specify underlayment, drip edge, flashing, and ice/water shield details in writing.
- Separate manufacturer material warranties from contractor workmanship warranties.
