Decking replacement in Normal

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 Normal and McLean County

Normal gets the full range — freeze-thaw cycling through winter, severe convective storms with hail and straight-line wind in spring and summer, and enough temperature swing between them to work every joint on the roof loose. Freeze-thaw is the quiet one: water finds a hairline gap in flashing, freezes overnight, expands, and opens it slightly wider, repeating through a McLean County winter until a joint that was watertight in October is leaking by March. Spring brings the loud damage, and derechos have put straight-line wind through this region at speeds that take ridge caps and whole shingle courses. Housing stock here is older than average, which means a lot of roofs where the flashing has already been through several decades of that cycle.

Normal has a population of about 52,736, and the housing stock here sets the pattern for what fails first on a roof.

Questions about decking replacement in Normal

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.
