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.
Katy is close enough to the Gulf to take the full force of tropical systems, and that is the storm profile that sets everything else. Hurricane wind is sustained for hours rather than gusting, which does something different to a roof — it works shingle tabs loose over an extended period and drives rain horizontally under courses that would shed any normal downpour. Then the heat and humidity do the slow damage. Roofs across Harris County run hot for most of the year, which ages the shingle and hardens every rubber and sealant component on it, and the humidity means that anything which gets wet inside the roof structure stays wet. A small leak here does considerably more damage over the same period than the same leak would further north, and mould becomes a problem much sooner.
Katy has a population of about 28,373, 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.
