This area sits in a cold, severe climate band, and steel panels contract in winter cold enough that an existing crack or dent becomes a stress point. A panel that looked fine in October can split along a seam by January once the metal has gone through repeated hard freezes. Because most of the housing stock here dates to the 2000s building boom, a huge share of doors in Meridian and the surrounding areas - Kuna, Eagle, Star, and the rest - are the same generation of steel sectional door, which means the same panel profiles are failing at roughly the same age across the whole region. That's useful for us on the parts side, since common profiles are easier to source, but it also means panel damage on a 20-year-old door is often the first sign the whole unit is due for more attention, not an isolated event.
