Ok, I hope someone can help me with this one, I have a garage 10.0 x 3.0 m, it has no insulation in the roof whatsoever.
I cannot do a warm roof as there is no space above as the house roof is almost touching the garage roof. (Bungalow)
The roof joists (200mm) one side are built into the wall, please see photo, so I can't fit over fascia vents. I cant fit upstand vents either as there is not enough room under the house roof.
My dilemma is do I fit 23 mushrooms (there are 23 joists) or do I make a hybrid roof with the insulation (Celotex) rammed up right to the deck, foam gun any gaps and fit a VCL?
