I. Factors That Influence the Cost of Roof Replacement
- Roof Size & Pitch Larger roof areas require more materials and labor. Steeper pitches increase difficulty, safety measures, and labor costs.
- Roofing Material Material selection (asphalt, metal, tile, slate, wood) dramatically affects per‑square pricing.
- Removal of Old Roofing Tear‑off and disposal of existing shingles or tiles incurs additional labor and landfill fees.
- Structural Repairs & Underlayment Damaged sheathing or rot discovered beneath the old roof adds repair costs. High‑quality underlayment or synthetic roofing felt improves longevity but raises material expense.
- Labor Rates & Region Local labor rates vary by market; metropolitan areas often command higher hourly wages. Prevailing wage laws or union requirements can further increase costs.
- Permits & Code Compliance Municipal permit fees and inspections are required in most jurisdictions. Upgrading to current building codes (e.g., ice‑and‑water shields in cold climates) can add material and labor.
- Roof Complexity & Features Dormers, skylights, chimneys, and multiple roof planes require specialized flashing and more time to install.
II. Cost of Replacing Different Roofing Materials
Material Type | Average Cost per Square (100 sq ft) | Lifespan |
---|
Asphalt Shingles | $350 – $500 | 15 – 30 years |
Metal Roofing | $700 – $1,200 | 40 – 70 years |
Clay or Concrete Tile | $1,000 – $1,800 | 50 – 100 years |
Slate | $1,500 – $3,000 | 75 – 200 years |
Wood Shingles | $600 – $900 | 20 – 40 years

Note: Regional pricing, brand selection, and roof complexity may push costs above or below these ranges.
III. The Roof Replacement Process
- Initial Inspection & Estimate A qualified contractor assesses roof condition, measures area, and identifies structural concerns.
- Permit Acquisition Contractor secures local building permits and schedules required inspections.
- Removal of Existing Roof Old shingles or tiles are stripped away; decking is exposed for inspection.
- Deck Repair & Underlayment Installation Replace damaged sheathing; install high‑quality underlayment or ice‑and‑water shield.
- Flashing & Ventilation Proper flashing around chimneys, vents, and valleys is installed. Ridge vents or other attic ventilation systems are fitted to manage moisture and heat.
- Roof Covering Installation New roofing material is laid according to manufacturer specifications.
- Cleanup & Final Inspection Job site is cleared of debris; a final walkthrough ensures workmanship meets standards.
