Another engineer argued that wind accelerates as it moves over a structure in a way that defies basic physics. The Rules are Finally ChangingIdeally, you’d think there are rules against this. They haven’t had specific rules regarding ethics in drafting damage assessments. No more “trust me, I’m an engineer.”How It Would WorkLet’s say you have a clay tile roof. They have to prove the wind speed was sufficient to lift that specific weight of tile based on recognized standards.
