What decking does and why it fails
Decking is the structural skin: it carries the roofing, resists wind uplift, and provides the nailing surface. It fails from chronic moisture — long-term leaks, condensation, poor ventilation — which delaminates plywood and swells OSB until fasteners won’t hold.
In Colton, the usual story is a slow leak that went unaddressed: by replacement time, sections around old flashing points are soft, spongy, or visibly rotted. This is why we inspect decking at every tear-off — no exceptions.
How we assess it (and how you can tell)
At tear-off, we walk every square foot: soft spots, delamination, visible rot, and moisture meter readings. You’ll see photos of every sheet we flag — no ‘trust us, it’s bad’ without evidence.
Pre-tear-off clues from inside: sagging between rafters visible in the attic, widespread staining on the deck underside, or a spongy feel underfoot (don’t walk it — tell us and we’ll check). These predict decking work before we start.
Cost: the per-sheet model
Reputable contractors price decking as a per-sheet line item in the contract — disclosed before work begins, with photo documentation of each replaced sheet. Typical Colton replacements need zero to a handful of sheets; full redecking is rare and usually tied to long-term neglect.
Red flag: a contractor who ‘discovers’ massive decking damage with no photos and no pre-agreed pricing. Our contracts state the per-sheet rate upfront — the only surprise is how little of it you usually need.
Why it matters for your warranty
Manufacturers require sound decking for system warranties — nailing new shingles to rotted wood voids the warranty you’re paying for. Proper decking replacement isn’t an upsell; it’s what makes the rest of the investment valid.
