Utah’s high-altitude UV intensity and thermal cycling compress roofing lifespan compared to manufacturer ratings. Standard 3-tab shingles: 15–20 years. Architectural dimensional shingles: 20–28 years. Class 4 impact-resistant shingles: 25–35 years. Standing seam metal: 40–70+ years. Concrete/clay tile: 50+ years. Annual inspection to catch granule loss, flashing deterioration, and sealant failure before water infiltration begins is the most cost-effective roofing investment. A $200–$400 annual inspection avoids $2,000–$8,000 in water damage remediation that a missed small failure can produce.
