Roof leak detection
Finding where the water actually gets in
Valleys carry water from two roof planes into one channel, which means they handle more volume than anywhere else on the roof and fail accordingly. Debris packs into the channel, water backs up under the shingle courses on either side, and the leak shows well below where it entered. Repair means opening the courses on both sides to reach the valley metal underneath, which is more work than a surface patch — and the reason a valley leak costs more than a boot.
Atlanta 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 Logan 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.
Atlanta has a population of about 1,669, and the housing stock here sets the pattern for what fails first on a roof.
Because reaching the valley metal means lifting shingle courses on both slopes and reinstating them correctly afterwards. A patch on top of the valley does not address what is underneath and tends to fail within a season.
Yes, and it is worth doing annually anywhere with overhanging trees. Most valley failures start as a blockage that backs water up under the courses; clearing it is far cheaper than the repair it prevents.
