Hi. On two occasions last month, snow managed to get into the attic through the 80mm downpipe air vents. This resulted in two big puddles of water which ended up dripping through our ceiling. As a temporary fix, I taped some polystyrene bags to the air vents and guided them into a plastic box. Although this solved the problem, it’s obviously not a permanent fix.
Has this happened to anyone before? Can you think of any cost-effective and simple solutions? Your help would be greatly appreciated --
I have attached images FYI
