Step 7: Installing Aluminum Trim and Roof
"After installing sheeting on the walls, the next step is to install aluminum trim and roofing. I used aluminum trim stock. It comes in a variety of sizes, and I used the 24 inch wide material. I installed aluminum on the corners to cover the exposed edges of the plywood sheeting. I also installed gutters over the windows and doors. Finally I installed aluminum sheeting on the roof with a double bend connection to make sure that it would be totally waterproof."
Thumbs up for this!
