When the Tear-Off Finds More Damage, the Supplement Is Yours to File

A supplement is the second written request a homeowner sends to the insurer after the first estimate is already on the table. It exists because a roof often cannot be fully scoped from the ground or from a ladder. The first estimate in most St. Louis roof claims comes from a visual walk and a set of photos. Once the old shingles come off, the crew can see the decking, the underlayment, the drip edge at the eave, and the flashing at walls and penetrations. Some of what they find is storm damage that the first walk could not confirm. Some of it is material or code work that the policy may or may not cover. A supplement is how that new information reaches the insurer in writing.

What the tear-off can reveal

Most supplements in the St. Louis area come from the same few places. Plywood or OSB decking that looked sound from the attic turns out to be soft or delaminated where water has sat at a valley or around a pipe boot. Hail bruises on the deck are not always visible from above, and they show up more clearly once the old felt and shingles are gone. Drip edge and starter strip that were bent by wind can crack when they are lifted. Ice and water shield at the eave may need to run farther up the deck than the original scope showed if the install sheet for the new shingle calls for it.

Each of these is a finding, and each finding needs its own photo, its own measurement, and its own line in the scope. A line that says replace deck as needed gives an insurer nothing to review. A line that says replace 140 square feet of 7/16 OSB at the north valley, with photos from three angles and the moisture reading taken on the day, gives a reviewer something to check.

A discovery is not automatically a covered item. The policy decides that, and the insurer decides how it applies to your roof. A homeowner should not assume that because the crew found rot, the insurer will pay for it. The supplement's job is to put the finding on the record with a date attached. Whether that finding is paid is a separate question, and it is answered under the policy wording, not by the fact that the roofer saw it.

Insurance claim: who files and who argues

Missouri law (RSMo 407.725) bars a roofing contractor from representing or negotiating a homeowner's insurance claim. A roofer cannot file the supplement as the homeowner's representative, cannot argue the line items with the adjuster, and cannot tell the insurer what it ought to pay. That work belongs to the homeowner, or to a public adjuster the homeowner chooses to hire, which is a separate decision with its own cost and contract terms. What a roofing contractor can do is document what the crew found, put a written scope with photos and measurements in the homeowner's hands, and attend as the contractor while the homeowner deals with their own insurer.

The same statute also bars the roofer from saying anything about paying, waiving or covering a deductible. That number stays out of the supplement conversation entirely. If it matters to your decision, take it to your insurer or to the agent who wrote the policy.

Timing and the policy wording

Your policy sets the rule on when additional damage has to be reported, and this page cannot replace it. Many homeowner policies ask the insured to notify the insurer promptly once new damage is discovered, and some tie the pace of the work to the insurer's ability to inspect. Read the section on duties after a loss and the section that describes how the claim is adjusted. Then ask the insurer, in writing, what it needs before the crew removes any more of the roof. Do not wait until the new shingles are on to ask that question.

Timing matters in late autumn for a practical reason. If the crew opens the roof and a rain arrives before the underlayment is down, the deck can take on water. That wet deck becomes its own finding, and it can complicate the photo record of what the storm did and what the rain did afterward. A roofer who tarps the open section at the end of each day and documents the tarp position is making that record cleaner. Ask about it before the first board comes up.

Your insurer may send its own inspector back to the roof to look at the new findings. That visit is the insurer's, not the roofer's to manage. The contractor's job is to be on the roof when it happens, to point to each finding, and to show the measurements already in the written scope.

What goes in your supplement packet

• The original estimate and every page of the scope, each with the date you received it.
• Each new photo as the original camera file, not a screenshot, with the date and the roof slope noted on the file name or in a short index.
• The crew's written list of findings, with a measurement for each one: square feet of decking, linear feet of drip edge, number of pipe boots or vents, and the length of any valley opened.
• A short comparison showing what your earlier photos looked like at the same locations, so the reviewer can see what has changed since the first walk.
• A copy of the insurer's acknowledgment of the original claim, so the supplement refers to the same claim number and the same policy.

Keep the packet in one folder. A reviewer who receives the findings in order, with a clear index, can answer them one by one. A reviewer who receives photos in five emails over three days will ask for the same set again, and that delay is usually on the homeowner's side of the file, not the insurer's.

What it costs

A supplement can add cost in two ways. The first is the labor and material for the finding itself, such as a deck section, a run of drip edge, or a flashing at a wall that the first estimate did not include. The second is the knock-on change to the rest of the roof, such as extra ice and water shield, a longer starter course, or added underlayment that the new work requires. A good written scope shows both, so you can see which is which.

Ask the roofer to price the supplement items on separate lines rather than folding them into a single added total. Each line should carry its quantity and its unit. A decking replacement, for example, should show square footage, the panel thickness and type, the labor to remove and reset the new sheets, and any fastening change the manufacturer's install sheet requires. A lump line that says decking allowance does not tell the reviewer what the number is for.

Also ask how long the open roof can wait while the insurer reviews the new findings. Some roofers will tarp and hold the section until a decision comes back. Others cannot hold it for long without the crew being sent elsewhere. That answer changes the timing of every item that follows, and it can change the cost if the crew has to come back a second time.

What to ask before the crew leaves for the day

1. Which findings did you see, and on which slope and at which location is each one?
2. Did you photograph the deck and the flashing before any sheet or piece was removed?
3. How is the open section covered tonight, and who checks it after rain?
4. Can you put the supplement scope in writing, with measurements and photos, by the time I need it for my insurer?
5. What does the insurer need to see from the roof before you can proceed with the next section?

If the crew finds something the first scope did not show, call Keys at (314) 220-2333 and ask for the written supplement before the next shingle comes off. Keep the tear-off photos in the same folder as the first set, and label each file with the slope and the date. The reviewer will read the packet in order, and a folder with a clear sequence is easier to answer than one that arrives in pieces.
