I think the biggest clue is when small cosmetic issues start turning structural. A bit of unevenness is fine, but once edges crumble or the slope changes, water damage can spread fast. It’s also easy to underestimate how much material moves during freeze-thaw cycles. DIY patches might hold for a season, but a properly compacted base lasts for years. It’s not always about appearance — it’s about protecting the whole surface from future damage.
