Caulk is not a permanent fix. This is what happens when it gets treated like one.
We stopped by a property in Troutdale for an inspection and found this at the parapet wall. The metal cap meets the stucco, and the sealant has cracked, pulled away, and left visible gaps. At that point it's not protecting anything.
Parapet caps and wall-to-roof transitions are high-movement areas. They expand and contract with every temperature swing, and standard caulk just can't hold up forever. It needs to be checked and redone on a regular schedule, not left alone until water starts showing up inside.
If your building has a parapet wall, the sealant joints should be on your maintenance checklist. Catching it here is a quick repair. Letting it go turns into a water intrusion problem that's a lot harder to trace and a lot more expensive to fix.
