Hi everyone
I was referred over here from the loft forum as I'm having trouble ventilating my loft space.
I have a Victorian semi-detached house with a slate roof and impermeable plastic undersarking. There's no obvious ventilation for the loft. One side is a brick gable end with the chimney breasts. There are no soffits and there doesn't appear to be any eave vents either. Theres no daylight coming in around the fascia boards.
There is not enough ventilation up there, and there is a fair amount of white mould on the wood. The condensation was terrible over Christmas, it was almost raining on the inside of the undersarking.
I have fitted 10 x Lap vents to try to improve ventilation but noticed that the overlaps in the undersarking are quite large and not all the vents separate the entire overlap - so they probably aren't as effective as I want them to be.
I'd be grateful for some opinions on the best way to ventilate it. I'll probably have it converted in the not too distant future so probably need to take that into account.
Is there a way I can make vents in the fascia boards? Or do I need ridge vents/vent tiles?
Also JohnD mentioned that the wood looks like it might have been wet - any opinions on that would also be great. I'm hoping they look okay to you all!
Thanks in advance
Tim
