I've never seen so much mouse sh*t in a loft ...

[Fallingditch]

Victorian detached house with a footprint of about 11m x 8m.  Roof constructed with three king post trusses.

 

Around 125mm rockwool insulation laid maybe 30 years ago?

 

Want to retain as a cold roof, but just lay some boarding to provide storage space. Boards will sit on top of the kink post lower chords, about 200mm higher than the ceiling, so that all works OK.

 

BUT here's the thing: there is a huge quantity of mouse shit on top of the existing insulation and I mean huge. It is everywhere - truly gross.

 

So it just doesn't seem right to ignore this issue, and lock the problem in

 

So am sorely tempted to start again - remove all the shitty (sic) old insulation and relay new.

 

But what would others do?

Sounds like a shitty (sic) job, but I say take out and replace, won't cost much other than your time. Invest in a good respirator though

Be grateful its just old, soft (now gone hard) and smelly.  One house I lived in had that plus rats' presents and many skeletons.   Its really dangerous stuff to walk around in (on) - it's the dust....
