Shingles lifted, creased, or blown off after wind

Yes, for two reasons. The exposed area lets water at the underlayment and deck, and the shingles around the gap have usually lost their seal too, which is why losses tend to continue in later, milder wind.

It lifted in the wind and folded, breaking the mat along the crease line. It may look intact from the ground but it is compromised and will generally fail early. Creasing is one of the main things a close inspection looks for after a storm.

Frequently because the adhesive strip had not yet sealed. Shingles installed in cold weather may not bond until sustained warmth arrives, leaving the roof more exposed to uplift in the interim unless the manufacturer's cold-weather provisions were applied.

Not necessarily. It depends on how widespread the damage is, whether matching material is available, and the condition of the rest of the covering. Widespread seal failure across several planes is a different conversation from a dozen shingles off one slope.

Possibly not exactly. Weathered asphalt changes colour and specific products get discontinued, so a repair on a prominent plane can be visible. That is sometimes acceptable and sometimes an argument for a larger scope, but it should be a decision you make knowingly.

Policies contain notice requirements and time limits that vary. Notify promptly instead of waiting for a contractor's report: early notice followed by documentation is a much safer sequence than the reverse.

There is no single reliable threshold: a shingle's actual wind rating depends on correct fastening and a fully sealed adhesive strip, so a properly installed, bonded roof can withstand more than the same product installed with too few nails or before it had time to seal.

Sometimes, if sustained warm weather returns before the next wind event and the seal was only partially broken. It is not something to count on, since a shingle that lifted once has a compromised seal and remains more vulnerable until it is checked or resealed.

Yes: the adhesive strip and the mat itself both age, and an older shingle nearing the end of its service life is generally more brittle and more likely to crease or lose its seal in wind than a newer one.

Yes: the plane facing the prevailing wind direction, and any plane with little upwind shelter, generally takes more sustained wind load than a sheltered plane, which is why damage is often concentrated on one side of a roof, not spread evenly.

This is not a recommended DIY fix. Improperly applied sealant can trap moisture, interfere with the shingle's designed drainage path, and does not address why the seal failed in the first place. Have a lifted or unsealed shingle assessed and correctly resealed or replaced.

It can go either way depending on the specific wind dynamics and detailing. Pitch changes how wind interacts with the roof surface, but fastening quality and whether the shingles have fully sealed matter more than pitch alone in most cases.
