A Sod Roof
Keeping moisture out is the first concern
I would like information on putting on a sod roof. Do you have information or good sources that I can look up?

Tom Silva replies I've never done a sod roof, but you're biggest worry will be
moisture. Make sure you install waterproofing (like an ice and water
shield) that prevents condensation inside the house, and insulate
underneath the roof with the foam insulation. Taking these steps will
create a thermal break and keep heat and cold from being transmitted
rapidly, which can cause condensation, or even leaking or ice dams.
