Hi just started to pull off old fascias ready for new, got to thinking should i leave some ventilation for existing roof void and insulation or will warm roof now make any vent unecessary? i feel that there ought to be some extra pir placed between joists but over wall plate up to ex deck level otherwise warm ,moist room air can reach the new fascias and condense out? am i being OTT?
