I am facing with the situation in converting part of my new garage into my office. I need to vent the 50mm gap above the ceiling insulation on a cold deck flat roof. I only know that during the last building regulation inspection.
Roof is flat fibreglass so no over fascia vents like you would do with pitched roof.
The fascia wood is screwed directly onto the end of the roof joists and there are no soffits to put a vent into .
I dont really want to put mushroom vents on the roof as it will mean a lot of holes( between each of 10 joists) and look messy.
what I really need is a louvered fascia board that is weatherproof but allows air in.
Does such a thing exist or do I just fit a load of small louvres?
