I have been searching and digging and got some pallets to break apart and put as siding. Would it be ok to put that on the roof too or should I go with the Tin roof? I have water protective plastic on the top, but still afraid it may leak, but at the same time, I am cheap and don't really want to spend anymore money if I don't have too. Only have front and one side done of the siding. Debating if I want to paint it, or leave it how its now. My wife likes it how it looks right now, but I kind of want to paint it and add some color too it. Will add some vent holes when it is complete. Here is a picture of what it looks like so far.
