Just curious.......... So I purchased 6 roofing panels from someone who was moving. I had to use a crane truck to load/unload them on a car hauler trailer. Each panel I was told weighs 500 pounds or so. They are approximately 8 feet by 11 feet. I was hoping to place them 3 long and butt 3 of them together so the total dimensions would be 24 feet x 22 feet. Obviously that's alot of weight to hold up. I have some dead standing ash trees that I could take down and make some big posts. I figured I could even make some huge posts up to 24 inches for where the 2 panels but up together if needed. I've been reading online about using untreated posts for post frame buildings. Some say treat the part that will in in the ground with tar or tar/kerosene. Others say put in a concrete pier/pillar and attach post to top of concrete pier(which defeats the purpose of pole building and jeopardizes lateral support) Was just wondering what your thoughts are and if anyone has done anything like I'm wanting to do. Obviously I do not want to go to the store and buy any lumber. I do have some cedar trees on the property but don't want to cut them down just to use them as posts. Thanks for the advice.
