Hello,
My house has a 1970s flat roof extension on it. It was re-roofed earlier this year. Treated chip board stuff across the tops of the joists, with rubber lining over the top and upvc Fascia boards around the tops of the walls. Loft insulation was added between the joists.
What I do not understand is how this roof could ever be ventilated the way the main pitched roof is, with its breathable felt and soffit vents which I might add. The flat roof seems completely enclosed and I am concerned about condensation and sweating in there. Any recommendations on how to cheaply and easily ventilate it? Perhaps some kind of vents on the Fascia boards with louvres that don't allow rainwater in? Any suggestions?
Thanks
