Valley leaks
Where two roof slopes meet
Metal almost never fails in the middle of a panel. It fails at the fasteners, where thermal movement backs screws out and flattens the neoprene washers underneath, and at seams where sealant has gone brittle. A screw standing proud by a couple of millimetres is an open hole, and there may be hundreds of them on a roof. Both failure modes are invisible from the ground and both are straightforward to fix — which is why a leaking metal roof rarely needs replacing.
Dunedin sits on a stretch of coast where hurricane exposure is the defining fact of roofing. Sustained wind drives rain horizontally under shingle courses that would shed any vertical downpour, and it works tabs loose over hours rather than tearing them off — so the roof reads as undamaged right up until the next storm. Between seasons, the heat and humidity across Pinellas County harden every rubber and sealant component and keep anything that gets wet from drying. The insurance picture matters as much as the weather here: Florida's market has reshaped how roof claims are handled, deductibles for named storms are calculated differently from ordinary ones, and documentation taken before any work starts is what decides how a claim goes.
Dunedin has a population of about 36,068, and the housing stock here sets the pattern for what fails first on a roof.
Not always, but they went in on the same day and have had identical weather, so if a number have backed out the rest are on the same trajectory. Doing the whole roof at once usually costs less than returning twice.
That is the normal presentation. Fastener and seam failures are not visible from the ground and often not obvious from the roof either without checking each one. The panel itself is almost never the problem.
