Flat and low-slope roof leaks
Ponding, seams and parapet flashing
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.
St. Marys sits close enough to the water that salt air is part of the roofing equation, and it is the part most people miss. Salt accelerates corrosion on every metal component up there — flashing, fasteners, drip edge, vent collars — so the parts of a roof that are supposed to outlast the shingles often do not. Add hurricane exposure, where Camden County takes both the wind and the horizontal rain that comes with it, and the older housing stock near the water with its steeper pitches, slate and tile sections and complex roof geometry, and the result is a market where leaks cluster at the junctions rather than in the open field of the roof.
St. Marys has a population of about 18,256, 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.
