Valley leaks
Where two roof slopes meet
Replacement stops being the expensive option and becomes the cheaper one at a specific point: when repairs are recurring in unrelated places, or the shingle has lost enough granule that the mat is exposed across the roof. Before that, repair is almost always better value. A proper replacement is a tear-off rather than an overlay, because the second layer hides the decking condition and shortens the life of what goes on top.
Tazewell 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 Tazewell 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.
Codes often allow one overlay, but it hides the decking condition, adds weight, and runs hotter — which shortens the life of the new covering. A tear-off costs more and is almost always the better value over the life of the roof.
Pattern rather than any single defect. Isolated damage from an event is a repair. Failures appearing in several unrelated places within a season, or visible mat across the field, means the covering is done.
