In need of creating a roof of sorts for a firewood rack. Trying to find
that happy median between durability and cost.

At the moment I'm leaning towards 3/4x4x8 BC pine plywood. This will be
covered by green tarps of which I have many.

Is there a different type of plywood or panel I should consider instead?

Also curious about corrugated plastic roof panels. Anyone use them for
similar projects?
