Roof was insulated with 8 inches of 40 PSI insulation. R40 at 0 degrees Celsius. Insulation was then covered with EPDM rubber.
Carried the insulation across my little bridge. Two layers of R20 for a total of R40.
Created a gutter with insulation cut at 45 degrees.
Covering the roof with three sheets of EPDM rubber with two feet overlap. No way I’m getting leaks?!
Waterproofing the roof and foundation.
