IMHO, no matter where you live, you will have to deal with some type of negative weather. The local building codes do not always reflect the inherent needs to deal with their particular weather issues. It is incumbent upon the homeowner to properly assess the weather risks for their home or airport. Where I live you cannot build without the proper engineered roof snow load and you typically cannot build in flood zones unless you are willing to pay a structural engineer to design mitigation based on 100 year flood data. We also experience constant winds and/or gusts in excess of 110 mph. How do I know this? Simple our anemometer was designed to withstand 110 mph which we saw before it broke in pieces.
