Valley leaks
Where two roof slopes meet
Water travels along rafters and decking before it shows on a ceiling, so the stain is rarely underneath the hole. Tracing the real entry point is most of the work on a leak call and the part that separates a repair that holds from one that fails at the next storm. Done properly it means time in the attic with a moisture meter, not a guess from the driveway — and where the entry point genuinely will not reveal itself, a controlled water test on the suspected area to reproduce it.
Woodford County gets the full range — freeze-thaw cycling through winter, severe convective storms with hail and straight-line wind in spring and summer, and enough temperature swing between them to work every joint on the roof loose. Freeze-thaw is the quiet one: water finds a hairline gap in flashing, freezes overnight, expands, and opens it slightly wider, repeating through a Woodford County winter until a joint that was watertight in October is leaking by March. Spring brings the loud damage, and derechos have put straight-line wind through this region at speeds that take ridge caps and whole shingle courses. Housing stock here is older than average, which means a lot of roofs where the flashing has already been through several decades of that cycle.
Usually. Staining patterns, moisture readings and the physical condition of flashing and boots tell most of the story. Where that is not conclusive, a controlled water test on the suspected area reproduces it without waiting for weather.
Almost always because the patch went where the stain was rather than where the water entered. Water can travel several feet along a rafter before it drops. Sealing the visible end does nothing about the gap further up the slope.
