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.
Berrien County is far enough south to take the inland remnants of Gulf and Atlantic hurricane systems, and that is the storm profile that matters here. By the time these systems reach Berrien County the wind has dropped below the headline numbers but is still sustained for hours, which does something different to a roof than a short violent gust — it works shingle tabs loose over an extended period and drives rain horizontally under courses that would shed a normal downpour. The heat and humidity do the rest. Roofs here run hot for most of the year, which ages the shingle and hardens every rubber and sealant component, and the humidity means anything that gets wet inside the roof stays wet.
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.
