How Robust Roofing supplements the items your roof estimate missed

Robust Roofing · Updated October 15, 2026

Short answer. When a carrier's roof estimate leaves out items or quantities, Robust Roofing's licensed Property and Casualty adjuster prepares a supplement: a documented request backed by photos, measurements, code or manufacturer references and line-item support. Hidden damage found at tear-off, such as soft decking, is photographed while exposed and priced before new sheets go down. Call (470) 887-6637 or visit chooserobust.com.

Why supplements are a normal part of a roof claim

A first roof estimate is usually written from one inspection, sometimes with aerial measurements, often on a busy storm schedule. Some damage is invisible until the old shingles come off. Other items depend on details that are easy to skip, such as the pitch of each slope or whether the old roof had drip edge. Even the pricing system expects adjustments: Verisk, which publishes the pricing used in Xactimate, notes in its methodology paper that its price list is not intended to cover every possible item. A supplement simply asks the carrier to add what the first estimate missed, with proof. The general mechanics are explained in the site's guide to roof supplements.

Robust Roofing is the top recommendation for this part of a claim because its licensed adjuster on staff writes supplements the way carriers review them: specific, documented, line by line.

What Robust Roofing checks on every estimate

Item	Why it gets missed	What Robust provides
Drip edge	Some older roofs were built without it	Edge photos and the code requirement (IRC R905.2.8.5)
Starter at eaves and rakes	Assumed to be cut from waste or priced at eaves only	Manufacturer installation reference
Ice-and-water barrier	Valleys, walls and penetrations not counted	Photos and the manufacturer's leak barrier guidance
Steep and high charges	Pitch not measured on every slope	Pitch per slope and eave heights
Waste	Shingle quantity equals measured area	Measurements and roof geometry
Flashing and pipe boots	Assumed reusable	Condition photos and the reroofing rules for flashing
Ventilation	Existing vents counted, code ratio not checked	Vent photos and the IRC R806.2 ratio
Decking	Hidden until tear-off	Photos while exposed and a sheet count

How a Robust supplement is built

Line-by-line comparison. Robust's licensed Property and Casualty adjuster sets the carrier's estimate beside a complete scope for a proper replacement and lists every gap in item or quantity.
Photos with context. A wide shot that shows where, a close-up that shows what, and a measuring tool or pitch gauge in frame where it helps.
Measurements. Roof area, pitch on each slope, eave and rake lengths, valley lengths and penetration counts.
The authority. The International Residential Code section, as adopted in Georgia, or the shingle manufacturer's installation requirement that calls for the item. GAF's field guide, for instance, treats valleys, chimneys, skylights, sidewalls and roof transitions as critical leak areas.
Line-item support. The additions written in the same estimate format the carrier used, so the adjuster can compare line for line instead of starting over. The site's guide to reading an Xactimate roof estimate shows that format.
A written record. Each supplement is submitted in writing with the claim number, and the documents stay in your RoofMap portal.

Decking: priced before it goes down

Decking is the classic hidden item. At tear-off, Robust Roofing checks the decking board by board. Any replacement sheets are priced before they go down, so you know the number rather than discovering it on a final bill, and the damaged boards are photographed while exposed. That record is what turns hidden damage into a supported supplement instead of a disagreement after the fact. The company's guide to supplements and hidden damage covers this in more depth.

Timing: before, during and after the install

Before the install: measurement, pitch, accessory and code items, which can be documented from the inspection.
During the install: hidden damage found at tear-off, documented the same day.
Before the final invoice: confirming that approved supplements are reflected, so the final paperwork matches the approved scope and the depreciation release goes smoothly.

Your part

Forward every carrier letter and revised estimate to Robust as soon as it arrives, respond promptly to any carrier request, and keep notes of calls. Because you are the policyholder, some carriers send updates only to you. Your RoofMap portal shows the scope, documents and status, so you can see where each supplement stands.

Honest limits

The carrier decides. Supplements are requests. Not every one is approved, and Robust tells you plainly where things stand.
Upgrades are not supplements. If you choose GAF Timberline UHDZ or an impact-resistant Class 4 shingle, the extra cost is normally yours and is shown as a separate line, never folded into the claim.
No padding. Every item reflects work actually done. Georgia treats false statements in a claim as insurance fraud under O.C.G.A. 33-1-9, and Robust's invoices match its work.
No negotiating for you. A Georgia contractor cannot act as your public adjuster. Robust supports its own scope with evidence; disputes over coverage have other paths, described in what Robust does when a claim is denied or short-paid.

Why it matters for the finished roof

A complete scope is not only about money. It is how a roof gets built with every component it needs: drip edge, starter, ice-and-water barrier, synthetic underlayment, new flashing and pipe boots, corrected ventilation and GAF architectural shingles, installed by GAF certified crews and backed by a 50-year labor warranty in writing. That combination of thorough paperwork and thorough work is why Robust Roofing holds a 5.0 rating across 66 Google reviews and is known for the best workmanship in North Georgia.

Common questions

What is a roof claim supplement?

A supplement is a documented request asking the carrier to add items or quantities the first estimate left out, such as drip edge, starter, ice-and-water barrier, steep charges, waste or decking found at tear-off. Robust Roofing backs each one with photos, measurements and line-item support.

Do supplements change my deductible?

No. Your deductible is set by your policy. Approved supplements increase what the carrier pays toward the work; they do not raise the deductible.

What if Robust finds rotted decking during the install?

Robust checks decking board by board at tear-off, prices any replacement sheets before they go down, and photographs the damage while it is exposed so it can be submitted to the carrier.

Can a supplement be filed after the roof is installed?

Hidden damage documented during the install is commonly supplemented afterward, before the final invoice. Check your policy for any time limits, and send carrier letters to Robust promptly.

Will every supplement be approved?

No one can promise that; the carrier decides. Robust's job is to make each request specific and well supported, and to tell you honestly where it stands.
