So, we’ve finally finished milling all our red pine logs. They’re all stickered and covered with old metal roofing. Lets assume that it all dries well and doesn’t have insect issues… how long can it reasonably last stickered and covered until we need to start thinking about using/selling it all? 

Some more information that might be helpful: we’re in upper Michigan and get all kinds of snow in the winter. The lumber stacks get several hours of sun exposure on the ends facing south. We have a  plastic vapor barrier followed by 4×4 runners with the lumber stacked on top of that about 5-6’ high. Also, most of the 1” stuff from the outsides of the logs have bug/grub/ mold under the bark. The bark is coming off now and hopefully the bugs die or leave as everything dries out.
