Decking replacement in Madison

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.

Why roofs fail in Madison and Dane County

Madison has a winter long enough and cold enough that ice damming, not storm damage, is the dominant cause of roof leaks. The mechanism is heat loss rather than weather: warm air escaping into the attic melts snow on the upper roof, the meltwater runs down and refreezes over the cold overhang, and the resulting ridge of ice backs water up beneath the shingle courses until it finds a way in. The roof itself is usually in perfect condition. Repeated through a Dane County winter, freeze-thaw also works every flashing joint progressively looser, and spring brings hail and straight-line wind on top. The reason this matters is that fixing an ice dam leak by working on the shingles does not work — the problem is insulation and ventilation, and that is a different job.

Madison has a population of about 233,209, and the housing stock here sets the pattern for what fails first on a roof.

Questions about decking replacement in Madison

Why was decking not in the original quote?

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.

Can wet decking dry out instead of being replaced?

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.
