Add two metal bars spaced out where the water will sit. The area will sag, rust and break easily w/o support.
How's the roof made? If it's clap board style, you need to use silicone on both sides to keep water out.
Otherwise, looks good.
It could be some kind of wainscoting.
I know when I made my 3x6ft hutch clap board style to match my house's siding, roof leaked like mad. Then I found out even the siding of my house had silicone to keep water out. opps
I was sitting here trying to remember if Dad told me what it is then I got a super smart idea! I'll just run outside and ask him! :slap:
He said it is just vinyl siding.
It has rained since we put them in there and I checked on them after it was done and all were still dry. The food in the feeders was still dry too which I was super pleased about! Course my buns are on the best part of the property. The house is right behind them, there is a huge bush on the right, and some trees on the left. One tree has branches that spread over where the growup pen is. It's rather nice. Not fool proof of course, but it is the coolest place in the summer. Not one sign of heat stress all summer!
