Leaky Roof Smells So Bad

[CathS 10]

Is it normal for a leak to smell like cat pee?? 

We have a dorma window which is leaking, waiting for roofer to come round. The room absolutely stinks though. Any idea why??

perhaps you have a rodent problem that you didn't know about. They can burrow through insulating material in all sorts of cavity spaces, the leak might be pulling water through a nest.

No I think there would be other signs if it were rats

Plus it's the loft ceiling, not walls or anything

We used to blame the cat for this smell in our bay window, it turned out to be damp in the bricks and bitumen/concrete floor/underlay. 

Resolved by proofing the brick walls and new carpet and underlay.

Thanks Annie. Hopefully when its dried out it may go away!

Rock wool insulation when it gets really wet can cause a smell similar to urine

you need to get the leak sorted and the insulation will dry  and the smell will eventually disappear
