Supplement
Also called: supplemental claim, supplemental estimate
Supplement is a request to add work to an approved claim after the original scope was set, normally because damage was found that nobody could see at the first inspection. It is the ordinary mechanism for changing a scope, not an exception to it.
What it means
A supplement is an addition to a claim that has already been scoped and approved. The adjuster inspected, the carrier agreed a scope, work began, and something turned up that the original scope did not include. The supplement puts the additional items in front of the carrier for approval.
It is worth stressing that this is routine rather than adversarial. Roofs conceal their condition. An inspection from the surface cannot see what the decking is doing under the underlayment, and nobody expects it to. Supplements exist because the first scope is necessarily written with incomplete information.
What typically drives one
Deteriorated or damaged decking is the classic case, discovered when the old covering comes off. Rotten or delaminated sheathing has to be replaced, it was invisible beforehand, and it was therefore not scoped.
Code-required components are another. Work that must be brought up to current requirements when a roof is replaced may not have appeared in the original scope, and whether it is payable can turn on whether the policy carries ordinance or law coverage.
Then there is damage the first inspection simply missed: a slope that was not walked, accessories that were not examined, collateral damage to gutters or vents.
Why timing is nearly everything
A supplement is an evidentiary claim, and roofing evidence is temporary. While the covering is off, the damaged decking is photographable, measurable, and undeniable. Once the new roof is on, it is a description in a document.
That is why work usually pauses when something significant is found, and why the call from the crew goes out immediately rather than at the end of the day. A supplement raised from the open roof with photographs is ordinary business. The same supplement raised a week later asks the carrier to take somebody’s word for the condition of material that is now buried or in a skip.
Common mistakes
Doing the work first and asking afterwards is the most damaging. Unapproved work may not be covered, and the person left holding it is usually the homeowner.
The second is bundling a supplement with a complaint about the original scope. Those are different arguments. A supplement for newly discovered decking damage is straightforward; wrapping it in a dispute about the original settlement makes it contentious for no gain.
The third is failing to document at the moment of discovery. The photograph that was not taken is the supplement that does not get approved.
On the call
Supplement calls are time-sensitive because the roof is usually open and the crew is standing on it. Capture what was found, whether photographs exist, and whether work has stopped, then escalate immediately. A supplement raised while the decking is exposed is straightforward; the same one raised after the roof is closed is very hard to prove.
This is how our agents handle it on storm appointment calls and day-to-day roofing answering service intake.
Questions people ask about supplement
- When should a supplement be raised?
- As soon as the additional damage is found and while it is still visible, which on a roof usually means while the covering is off and the decking is exposed. A supplement supported by photographs of the open roof is a different proposition from one raised after everything has been closed up.
- Does a supplement reopen the whole claim?
- Not normally. It continues under the same claim number and addresses the additional items rather than reconsidering the settled ones. The carrier reviews the added scope, and the approved supplement is paid on the same basis as the original, subject to the same depreciation treatment.
- Can a homeowner be billed for work that was never supplemented?
- That is a contract question between the homeowner and the contractor rather than an insurance one, and it is exactly the situation to avoid. Work carried out without approval may simply not be covered, leaving the homeowner to fund it, which is why approval should precede the work wherever possible.
