When rotten or deteriorated plywood is uncovered during a reroof, the affected sheets are removed and replaced with new decking before the new underlayment and roofing go on. This is normal, expected on older roofs, and non-negotiable: new waterproofing installed over compromised decking has nothing sound to fasten to and hides a structural problem that will only worsen. Reputable contracts anticipate this with a stated price for decking replacement, and reputable crews document what they find with photos.
Why Decking Rots
Years of small leaks — around old penetrations, at failed flashings, under aged underlayment — wet the plywood repeatedly. In Southwest Florida humidity, repeatedly wetted plywood delaminates and decays. Poor attic ventilation accelerates it. Much of this is invisible until tear-off, which is why decking condition is the classic reroof unknown.
How It Is Priced
Because nobody can see under the roof before tear-off, decking replacement is typically priced in the contract as a per-sheet or per-square-foot rate beyond a stated allowance. Before signing any reroof contract, confirm: the rate, whether any decking is included in the base price, and that discovered rot will be photographed before replacement so you can see what you are paying for.
Fastening and Inspection
Replaced and existing decking is re-nailed to current fastening requirements as part of a permitted reroof, and decking condition and fastening are among the items reviewed in the inspection process that accompanies a permitted roof replacement in Collier County. Requirements can change, so the permit and its inspections reflect the code in force at the time of the project.
Does Rot Mean the Whole Deck Goes?
Rarely. Most reroofs on older Naples homes involve replacing some sheets — commonly concentrated at eaves, valleys and around old leak sites — not the entire deck. Widespread decay does occur on roofs that leaked chronically for years, which is one more argument for fixing leaks promptly rather than living with them.
What This Looks Like in the Field
At an older home in Quail West, we found a screw-down tile roof with accumulated hurricane damage: screws pulled out of the plywood decking from tile uplift, and water damage in the spray-applied insulation below — the kind of hidden decking problem that only tear-off reveals, and exactly why decking is priced as a confirmed rate rather than guessed at up front.

Related Questions
How do I know if I need a roof replacement instead of a repair?
Age, extent of damage, and deck condition are the deciding factors. A roof nearing or past its expected service life, with damage spread across multiple areas, or with soft or rotten decking discovered during any repair, is typically better served by replacement than another patch. A single localized leak on an otherwise sound, mid-life roof is usually a repair. Craft Roofing (Florida Certified General & Roofing Contractor, CGC1540219 & CCC1336696) evaluates the roof in person before recommending either path.
How long does a roof replacement take in Naples, FL?
Most residential reroofs in Naples and Southwest Florida take a few days to about a week from tear-off to final inspection, depending on roof size, material (tile and metal generally take longer than shingle), and weather. Summer's near-daily thunderstorms can add delays since a roof mid-tear-off needs dry-in protection before rain arrives, so scheduling around the forecast is part of the process.
What roofing materials work best for a replacement in Naples?
Concrete and clay tile, standing seam metal, and architectural shingles all perform well in Naples when properly installed, with the underlayment beneath doing most of the real waterproofing work regardless of the surface material chosen. Tile is the traditional look for the area and highly durable; metal offers strong wind performance and a longer service life at a higher cost; shingle is the most economical option. The best fit depends on the home's structure, budget, and the owner's priorities.
What happens if rotten plywood is found during a reroof?
It's a common discovery once the old roofing material is torn off, especially on older homes or roofs with a history of slow leaks. Any soft or rotten decking is cut out and replaced with new plywood before the underlayment and new roofing go down — installing over compromised decking isn't done, since it can't hold fasteners properly and would undermine the new roof from day one. This adds modest material and labor cost but is standard practice, not a sign something went wrong.
Does a roof replacement in Naples require a permit?
Yes. Roof replacement is permitted work under the Florida Building Code, and Collier County requires a permit and inspections for reroof projects. Craft Roofing handles the permitting and inspection process as part of a replacement project.
