Was planning on getting more sheets up today but as soon as I started to move the backhoe crane to grab some more the wind got up. it was supposed to blow all day after switching from the South to the North West I caught it during the lull during the change of direction. 5 to 10 MPH breezes don't seem like much until you think about wrestling a sheet of metal that is half as large as a the canopy of a parachute in area and you currently only have a single sheet to stand on things can go south in a hurry. once I have 3 or 4 sheets down the risk management factor drops by a huge factor For 2 or 3 guys it would be a moot deal just fly them up and shift them one at a time in place with a guy on either end and a guy starting somewhere near the middle to get the first couple of screws in. In the past I've been on roofs with a stack of sheets in winds so bad the crane operator refused to bring us another bundle.
