We had our house re-roofed a few weeks ago and I noticed that my attic is more drafty.
I live in the UK and my house was built in the 1960s. It is a semi-detached bungalow.
I'm not sure what the old underlay was, but it was pretty heavy duty looking. It was a black rubber / plastic kind of material.
The roofer installed Protect VP400 Roofing Underlay with Redland Double Roman 50 tiles and semi round Redland ridge tiles. He replaced all the battens.
It's quite stormy here at the moment and I noticed more of a draft in the attic. More so than before the new roof. I checked around for light coming through but there was none. No leaks that I could detect.
Any ideas if this is normal and the result of a more modern roofing system or is there a problem with maybe some loose tiles and the underlay is preventing rain from getting in?
