Discussions with the customer lead to a change in design. I built another head house and moved the taller one to the center bin.
I also started laminating the head houses and roofs with corrugated siding. There are two methods I use to laminate sheeting. For large ares I uses 3M spray contact adhesive. For small panels such as these I use plastic cement but only around the perimeter to avoid buckling.
I decided to use the corrugated siding on the roofs. I will be painting them a different color than the sides.
