Roller doors can be the weak point in a shed/garage as they can flex and pop out of the tracks under intense wind gusts espcially domestic types as they are pretty thin material. Advice was to park a vehicle close inside with suitable padding to prevent them blowing in.
Industrial roller doors typically fitted with chains or in excess of 2.4m wide and over 3m high are typically made of thicker material and can withstand higher wind loads.
