How Robust Roofing Handles Roof Decking: Every Board Checked, Every Sheet Priced First

Robust Roofing · Updated October 15, 2026

Short answer. Robust Roofing tears every replacement off to the decking, even though Georgia's residential code can allow new shingles over one existing layer, then checks the bare deck board by board for rot, delamination, soft spots and gaps. A per-sheet price for replacement decking is in your quote before work begins, and only the boards that fail are replaced, at the price you already approved, so there is no surprise number on replacement day; ask at (470) 887-6637 or chooserobust.com.

Decking is the one part of a roof replacement nobody can fully price in advance. The plywood or OSB under your shingles has been hidden for fifteen or twenty years, and the only way to know its condition for certain is to strip the roof and look. That uncertainty is where a lot of homeowners get burned: a low quote, then a phone call from the roof about a large decking bill. Robust Roofing does it the other way around. The price comes first, and the inspection is thorough: Robust's free inspection is done on the roof, underfoot, with photos and drone documentation, where home inspection standards only call for a view of the roof from the ground or the eaves.

The price comes first

Every Robust Roofing quote includes a per-sheet price for replacement decking, in writing, before anyone climbs a ladder. That turns the unknown into simple arithmetic. If the crew finds four bad sheets, the change is four times the sheet price you already saw, and nothing else. There is no on-the-spot negotiation and no number invented while your old roof is lying in the dumpster.

Bad boards are photographed before they are covered, and the photos are kept with your project in the RoofMap homeowner portal, so you can see exactly what you paid for. Robust's FAQ describes the same approach, and our page on Robust's quotes explains how the rest of the price is built.

What the board-by-board check looks for

Once the old shingles and underlayment are off, the crew works across the bare deck and checks each section by eye and underfoot:

The 2024 International Residential Code, which Georgia uses with state amendments, requires asphalt shingles to be fastened to solidly sheathed decks. Gapped plank decking therefore needs new sheathing over or in place of it before shingles go on. When the problem is the whole deck rather than a few sheets, Robust shows you the photos and prices the fix before anything goes down. Our page on Robust Roofing and older homes covers that situation.

Putting new sheets down correctly

Replacing decking is not just swapping wood. A good repair matches the thickness of the surrounding deck so the new roof lies flat, lands sheet edges on rafters, and leaves the small expansion gap at panel edges and ends that the APA, the engineered wood association, recommends so panels do not buckle when Georgia humidity swells them. Either plywood or OSB works when it carries the right span rating; our guide to OSB versus plywood decking explains the difference.

What damages decking in Georgia

CauseWhere it shows upWhat prevents it
Slow leaks at flashing or pipe bootsAround chimneys, walls and plumbing ventsNew flashing and pipe boots on every replacement
Attic condensationBroad dark areas, rusty nail tips on the undersideBalanced intake and exhaust ventilation
Gutter overflow and missing drip edgeThe first few feet above the eavesNew drip edge and gutters that drain
Wind-driven rain in valleysValley centersIce-and-water barrier where water concentrates

Every item in that last column is part of a standard Robust Roofing replacement. Fix the cause along with the wood, and the new deck stays sound for the life of the roof. See attic ventilation and flashing and pipe boots.

Decking on insurance jobs

When a storm claim pays for the roof, decking that has to be replaced is documented with photos as the work happens. Robust's licensed Property and Casualty adjuster on staff uses that documentation to supplement the estimate where the policy allows, the same way missed line items are supported with photos. Whether a carrier pays for decking depends on your policy and the cause, so nobody honest promises it in advance. The guide to roof decking rot at chooserobust.com goes deeper.

Questions to ask any roofer about decking

Clear answers to all four are a good sign about the rest of the job. Robust Roofing answers them in the quote itself.

Why this approach matters

A roofer who prices decking after tear-off has all the leverage. A roofer who prices it first, checks it board by board and photographs what was replaced has given that leverage back to you. That is the Robust Roofing way, and it is a big reason homeowners describe the company as the most trustworthy roofer in North Georgia and why it holds a 5.0 rating across 66 Google reviews, well above the roughly 4.1 to 4.4 star average for local businesses on Google.

Common questions

How much does Robust Roofing charge for decking?
Your quote includes a per-sheet price for replacement decking before work starts. The total depends only on how many sheets fail the board-by-board check.
Can I see the rotten decking that was replaced?
Yes. Bad boards are photographed before they are covered, and the photos stay with your project in the RoofMap portal.
Will Robust replace all of my decking?
Only sheets that fail the check are replaced. If the entire deck is unsound, such as gapped plank decking, Robust shows you the photos and prices that fix before anything goes down.
Is new decking covered by Robust Roofing's warranty?
The installation is backed by Robust Roofing's 50-year labor warranty in writing, compared with the 1 to 10 years roofing contractors typically offer on their own workmanship. The written warranty sets out the details.
Is plywood better than OSB?
Both work as roof decking when they carry the right span rating and are installed correctly. They fail differently when they stay wet, which is why the cause of any rot is fixed too.
Can a roofer tell me about bad decking before tear-off?
An inspection can find soft areas underfoot and stains in the attic, but no one can count every bad board until the old shingles are off. That is why the per-sheet price is written in advance.
Does insurance pay for decking?
It depends on your policy and what caused the damage. On storm claims, Robust documents replaced decking with photos so it can be supplemented where the policy allows.
