Valley leaks
Where two roof slopes meet
Decking is the structural sheet the roof covering is fixed to, and it is the thing a long-running leak destroys. Plywood or OSB that has been repeatedly wet delaminates and loses the ability to hold a nail, which means new shingles over it will not stay fixed. It is found during a repair rather than before — nobody sees it until the covering comes off — so it is usually a variation on the original scope rather than something quoted up front.
Cameron County 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 Cameron 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.
Because it cannot be seen until the covering is lifted. Any honest quote prices decking as a per-sheet rate that applies only if it is needed, rather than guessing at it — and tells you before replacing more than was discussed.
Sheets that got damp once and dried quickly are usually fine. Sheets that have been repeatedly wet delaminate — the plies separate — and that is permanent. The test is whether it still holds a fixing.
