Storm seasons that find the same weak joint every year?
- Leaks that follow named storms rather than ordinary rain
- Flashing patched more than once, tar over tar
- Damp appearing far from where it must be entering
Why it happens in North Carolina: North Carolina runs from hurricane-tested coast to freeze-prone mountains, with most of its people in a Piedmont that gets storm rain in quantity. Flashing quality decides more chimney outcomes here than frost does. On the coast, salt-air metal corrosion joins in.
What fixes it, and what it costs
Storm rain arrives sideways and under pressure, and it finds what vertical rain forgives: the lifted flashing edge, the flush crown, the hairline joint. Storm-proofing is ordinary work done properly: step-and-counter flashing cut in, crowns with real overhangs, caps that stay put, checked on the storm calendar. Then the named storms pass and the ceiling stays dry.
