Roof cost by material in Arizona
Roofs are priced per square (100 sq ft). An average US home is about 20 squares. Prices are localized to Arizona labor; the last column is what each material costs per year of life — often the real deciding number.
| Material | Lifespan | Total (20 sq) | Per year of life |
|---|---|---|---|
Architectural asphalt shingle The default US roof — best cost-per-year for most homes. Wind: up to 130 mph. | 25–30 yr | $6,850–$11,750 | $350/yr |
Flat / low-slope (TPO, EPDM)This page For flat and low-slope roofs; single-ply membrane over the deck. Wind: membrane, fully adhered. | 20–30 yr | $7,850–$15,700 | $450/yr |
Standing-seam metal High upfront cost but the lowest cost-per-year; sheds snow, resists hail and fire. Wind: 140+ mph. | 40–70 yr | $17,650–$31,350 | $450/yr |
Clay / concrete tile Longest-lasting; needs a structure rated for the extra weight. Wind: 125+ mph. | 50–75 yr | $19,600–$39,200 | $450/yr |
