Metal roof leaks
Fasteners, washers and seams
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.
Coppell sits in one of the most active hail corridors in the country, and hail is the roof killer here in a way that is easy to underestimate. The stone rarely punches through a shingle. It bruises the asphalt mat beneath the granule surface, leaving a soft spot that sheds water for another season or two and then fails — which is why a leak in Dallas County so often traces back to a storm the owner had stopped thinking about. Insurers know the pattern and scrutinise the gap between storm date and claim, so the roofs that get paid for are the ones that were documented when the hail fell rather than when the ceiling stained. Wind arrives with the same systems and does the quieter damage: lifting tabs, breaking the seal strip underneath, and leaving a roof that looks untouched from the driveway.
Coppell has a population of about 41,386, and the housing stock here sets the pattern for what fails first on a roof.
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.
