Roof lifespan in Idaho is different than national averages. Freeze–thaw cycles, snow loads, wind, and summer UV all add up. If you live in Meridian, Boise, Eagle, Kuna, or Nampa, use these ranges as realistic expectations.
Typical lifespan by roofing material
3‑Tab asphalt
15–18 years is common in the Treasure Valley, especially with poor attic ventilation.
Architectural shingles
20–30 years with better wind performance and thickness.
Metal roofing
40–70 years depending on panel type, coating, and installation.
What shortens roof life in Meridian & Boise
- Ventilation problems that bake shingles from underneath.
- Ice dams and repeated freeze–thaw at the eaves.
- Wind uplift from storms that loosen tabs and ridges.
- Past repairs that were “patched” instead of fixed at the source.
