Underlayment replacement
The secondary barrier under the covering
Attic ventilation works as a pair: intake low at the soffits, exhaust high at the ridge. Get the balance wrong — or block the intake with insulation pushed into the eaves — and the roof space stops breathing. The result shows up as condensation on the underside of the decking, as shortened shingle life from trapped heat, and in colder parts of the state as ice damming, because a warm roof melts snow that then refreezes over the cold overhang. A lot of apparent leaks are actually ventilation problems.
Chambers 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 Chambers 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.
Routinely. Condensation forming on cold decking drips onto insulation and shows up as damp patches that behave almost exactly like ingress. The tell is that it tracks cold weather rather than rain.
No. Mixing exhaust types — ridge vents and powered fans, say — can make a fan pull air from the ridge instead of the soffits, which short-circuits the whole system. Balance between intake and exhaust matters more than total area.
