A shed that’s started to lean has a way of looking worse every time you glance at it. Sometimes it’s purely cosmetic and easy to correct. Sometimes it’s the structure quietly telling you the foundation has moved. The trick is knowing which one you’re dealing with, because they get fixed very differently.

You step into the shed, the floor gives a little near the door, and you make a mental note to deal with it later. That soft spot is worth more attention than it gets, because the floor is the one part of a shed that takes water, weight, and time all at once. When it starts to go, it usually tells you something about the whole structure.

A little dip in a shed roof is easy to ignore. It sat fine for years, so what’s the harm in another season? The harm is that a sagging roof is almost never the actual problem. It’s the symptom. Something underneath is giving way, and the sag is just the part you can see from the yard.
