How often a roof needs replacing depends mostly on the material and on the local climate. Memphis summers are hot and humid, and the area sees regular severe storms, so roofs here often wear out faster than manufacturer warranty periods suggest.
By the numbers
- 3-tab asphalt shingles: 15 to 20 years. Architectural shingles: 20 to 25 years. Metal, tile, and slate: 40 to 70+ years.
- Hail in the Memphis area peaks in May, and March through June accounts for 74% of severe hail reports.
- In IBHS testing, repeated smaller hail left weathered shingles about 10 times more vulnerable to later severe hail.
Typical lifespans in the Memphis area
- 3-tab asphalt shingles: 15 to 20 years
- Architectural asphalt shingles: 20 to 25 years
- Metal, tile, and slate: 40 to 70 years or more with proper maintenance
What shortens a roof’s life
- Hail and wind damage that knocks off granules or loosens shingles.
- Poor attic ventilation, which traps heat and bakes shingles from below.
- Trees that drop debris and keep the roof shaded and damp, encouraging algae and moss.
- Missed maintenance and small leaks left unrepaired.
Signs it’s time to replace
Look for curling or cracked shingles, heavy granule loss in the gutters, multiple leaks, or daylight through the attic boards. If you’re seeing these, a roof inspection will tell you how much life is left. Learn more about roof replacement.
