A roof replacement is one of the largest home improvement expenses you'll face. Prices vary by a factor of 5x depending on material and roof complexity, making it critical to understand what you're paying for.
Roofing Cost by Material
| Material | Per Sq Ft | Average Home | Lifespan |
|---|---|---|---|
| 3-tab asphalt shingles | $3.50–$5.50 | $7,000–$14,000 | 15–20 years |
| Architectural shingles | $4.50–$8.50 | $9,000–$21,000 | 25–30 years |
| Standing seam metal | $8–$16 | $16,000–$40,000 | 40–70 years |
| Clay tile | $10–$25 | $20,000–$50,000 | 50–100 years |
| Slate | $15–$40 | $30,000–$80,000 | 75–150 years |
What Should Be in Your Quote
A complete roofing quote should include: tear-off and disposal of old materials, new underlayment (ice & water shield in cold climates), drip edge and flashing, ridge vents or other ventilation, cleanup and haul-away, and a workmanship warranty (minimum 5 years). If any of these are missing, the quote is incomplete and you'll face surprise charges.
Red Flags on Roofing Quotes
Price per "square" without defining it: A roofing "square" is 100 sq ft, not 1 sq ft. Make sure you and the roofer are speaking the same language.
No mention of ventilation: Proper attic ventilation extends roof life by 25%+. If the roofer isn't addressing it, they're cutting corners.
Huge deposit: Never pay more than 30% upfront. The industry standard is 10-30% deposit, with the balance due on completion.
