A roof collapse claim turns on one defined word

A roof rarely fails on the worst night of the storm. It fails a few days later, once a foot of wet snow has been through a thaw and a refreeze and weighs several times what it did when it landed, or when a low-slope commercial roof with a blocked drain has been holding standing water since the rain stopped. The moment itself is unmistakable — ceiling on the floor, a ridge line that is no longer straight, a truss chord split at the connection. What happens next almost never helps the claim. The building is unsafe, so a contractor shores it; the damaged structure is cut out and hauled away; and the physical evidence of why it came down leaves the property within days, before anyone has asked it a single question.

Whether any of that is a covered collapse depends on a word the policy defines for itself. Most current Illinois homeowners and commercial property forms exclude collapse in the general exclusions and then give a limited amount of it back as an additional coverage, available only where the collapse was caused by something on a short list — the weight of ice, snow or sleet, the weight of rain that collects on a roof, the weight of contents, equipment or people, hidden decay, hidden insect or vermin damage, or defective materials and methods where the failure happens while the work is going on. The same forms then define the word narrowly: an abrupt falling down or caving in, with the result that the building, or the part of it that came down, can no longer be occupied for the purpose it was built for. And they say the opposite directly. A building that is still standing is not in a state of collapse merely because it is cracking, bulging, sagging, bending, leaning, settling, shrinking or expanding, and neither is a building that is in danger of falling down. A roof everybody on site can see is dangerous can still sit outside that definition.

That is not the end of the claim, and it is the point at which people give up too early. Older forms that never defined the word have been read more broadly than the current ones, so the first thing worth establishing is which version is actually attached to your declarations page rather than which version the adjuster is describing on the phone. And where the damage genuinely does not meet the collapse definition, the weight of ice, snow and sleet is an insured peril on most forms in its own right: direct physical damage to the roof structure — split rafters, crushed trusses, a deflected deck, connections torn out of their bearing — is claimable under it whether or not anything fell down. The two routes are worded, limited and argued differently, which is why a file built entirely on the collapse coverage can be denied on the definition while the same damage was payable the whole time under the peril.

Cause is the other half of the file, and it is where the age of the building does its work. The give-back covers decay that was hidden. Deterioration that was visible, known or already reported — a soft spot somebody had noticed, rot at a bearing point recorded in an earlier inspection, a roof at the end of its service life — is precisely what the wear, tear and deterioration exclusions exist for, and a carrier that can show the decay was apparent has a real argument rather than a rhetorical one. So the work runs in both directions at once. An engineering report establishes what failed and in what order, while the building’s history — prior inspections, past repairs, the age and condition of the covering and the structure, what could and could not be seen from anywhere a person normally goes — is assembled before anyone is asked to remember it. We document the failed structure in place, photographed and measured, before it is shored and cut out; we get the reason for every removal in writing; and we scope the rebuild to include what a first estimate leaves off, including the code upgrades that rebuilding structure triggers. Where the failure also let the weather into the building, that half of the loss is worked the way we work any water damage claim, and the winter conditions behind it the way we work ice and snow damage.
