Nothing blew off my roof. Can there still be wind damage?
Yes, and it is the normal case rather than the exception. Shingles are held down by a strip of adhesive that softens in heat and bonds each course to the one below. A gust can break that bond and set the tab straight back down, so the roof looks exactly as it did while the shingle is now loose. The next storm is the one that takes it somewhere.
What the sealant strip does, and what breaks it
Every asphalt shingle has a line of adhesive across it. Heat softens it after installation and it bonds to the course above, which is what turns a stack of separate shingles into a single surface that wind cannot get under.
Wind damage is usually that bond failing rather than the shingle tearing. Once the seal is broken the tab can lift and drop repeatedly, and each cycle works the nails and creases the mat. A creased tab has a fold across it that will not lie flat again, and that crease is the line it eventually fails along.
It runs in lines, not patches
Hail lands scattered across a slope because it falls. Wind arrives from a direction, so wind damage follows edges: the windward rake, the ridge line, the first course above a gable end, and the row directly downwind of anything that accelerates air over the roof.
That is the practical difference when you are looking. A row of tabs standing slightly proud along one edge, all at the same height, is wind. Dark circular spots scattered without a pattern are hail. A roof can have both from the same storm.
Why it gets under-claimed
Nothing is on the lawn, so nothing prompts a phone call. The homeowner looks up, sees a complete roof and assumes the storm passed them. Six months later a smaller storm takes a run of tabs off and the date of loss for that damage is now the recent, minor event rather than the one that actually caused it.
Policies generally run their time limits from the date of loss rather than from the date you noticed, which is the reason to have a roof looked at within weeks of a storm you remember rather than after the first leak.
What an inspection is actually doing about it
The test is mechanical. A shingle is lifted by hand to see whether the sealant strip is still bonded, and if it releases with no resistance across a run of the roof, the bond is gone whatever the surface looks like.
That has to happen on the roof. It is the one part of a storm inspection a drone cannot do, because it is a question about adhesion rather than about appearance.
Related questions
How fast does wind have to blow to do this?
Lower than most people expect, and it depends far more on exposure than on the number. An open lot with nothing upwind takes a gust at full strength that a sheltered street never feels.
Can I check this myself from the ground?
Partly. Look along the edges for a run of tabs sitting slightly proud, and look for creases across tabs. What you cannot do from the ground is test whether the seal has released.
If nothing is leaking, does it matter?
It matters because the roof is no longer a single bonded surface. Water is not the immediate risk; the next storm is.
Will an adjuster accept wind damage with no missing shingles?
Routinely, when it is documented properly. Photographs of creased tabs and of the seal releasing across a run are what make it legible in a scope.
