Ultraviolet exposure breaks down finishes and seals, humid air works its way into weak points, and repeated expansion and contraction slowly loosens caulk, hardware, and weatherstripping.

That range is more realistic than promises like "lifetime," because the climate here is hard on weak products and sloppy installation.

That matters, because some problems can be repaired, while others are simply the early signs of end-of-life.

If a home takes on repeated weather stress, impact, or constant sun exposure, replacement may be the better move before the typical lifespan is reached.
