Ceiling leak and water stain
Stains, bulges and damp patches inside
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.
Troy 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 Miami 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.
Troy has a population of about 26,305, and the housing stock here sets the pattern for what fails first on a roof.
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.
