Flat and low-slope roof leaks
Ponding, seams and parapet flashing
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.
Dade County sits in the Blue Ridge foothills, which puts it in a different roofing climate from most of Georgia. The mountains get real freeze-thaw cycling: water works into a hairline gap in flashing during the day, freezes overnight, expands, and opens the gap a little wider. Repeat that through a Dade County winter and a joint that was watertight in October is leaking by March. Ice at the eaves is the other one — meltwater running down a warm roof refreezes over the cold overhang and backs up under the shingle course, which is how water ends up inside a roof with no visible damage at all. Steep pitches shed snow well but make access harder, and older stock here runs to standing-seam and pressed metal, which fails at the fastener rather than the panel.
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.
