Oh the visual of a chickens tongue stuck to the chairAs I recall metal roofing was the opposite of polycarbonate roofing, but I don’t know why. You have to consider the expansion and contraction characteristics, and what you’re attaching to. The Suntuf roofing I used (polycarbonate) say to attach on the crests, and we used special supporting pieces under them, placed on the purlins first. We still had to be careful not to screw down too much. Our metal-roofed barn, roofed in 2004, has the screws in the valley, so closest to, right on the purlins, and with no support pieces under it. Our roof style is a crest and then maybe eight inches of flat, then a crest again.
The mistakes our builder made was using fairly green rough cut lumber from the local hilltop sawmill here. They don’t have a kiln. Then our builder left them out to dry further, okay, but then we got freezing rain /snow. So he was scraping them off, kind of ineffectively….overall an impossible situation. The result is that our barn leaks in a few places. Now that there are a few screws coming up too, I think if we got up there and tightened them all everything might be fine.
Tax and question: discovered the gang has found there’s something tasty about the tubing of this lawn chair in their run. I think it’s an aluminum frame. Does aluminum oxidize in the air and produce a yummy but toxic element? Should I be worried? Well I am worried, should I be? Besides getting their tongues stuck on it in the freezing cold, which for some reason doesn’t happen. Here’s Butters pecking at it.
