I was wondering if Stirling Board is better for the top of roofs than Plywood. I have several shop bought roofs that use Stirling Board and they never seem to have any condensation issues. However my home made ones using plywood seem to get black mold on the underside. The ventilation on my home made roofs is routed exactly the same as the shop bought ones.
