Im renewing the roof on my garage, it measures 30ft x 15ft. Its a sloping roof, with joists ever 3 feet. Im planning to strip the corrugated sheets off the roof, and replace them with new ones.
This is the plan
1. Lay 12mm or 18mm plywood boards as decking on top of the joists, then lay a rubber membrane and tack it to the plywood, then lay 16ft corrugated sheets on top.
My question is what type of membrane is best to use under the roofing sheets?
thanks
