Just in case you have a recycler full of cans from the holidays…
…Chicken coop roof!
Make Shingles and Siding Out of Aluminum Cans (Beer Can Roof)
I haven’t tested this long term but it seems to work on my chicken coop. Here’s the rundown:
Using scissors or tin snips cut the ends off an aluminum soda/beer can and cut down the middle of the can to make a flat rectangular piece of aluminum. Then you lay the flat piece into the forming die and press it by stomping on it or hitting it with a hammer. In this Instructable I’ll show how to make the die and then lay out the shingles on a roof.
