Yes, and it's one of the more expensive consequences of a squirrel infestation that homeowners often don't anticipate. Many Ascot properties, particularly the larger detached homes common across the area, have had significant investment put into loft insulation, whether as part of a renovation or an energy-efficiency upgrade. Squirrels moving into that same roof space can undo a meaningful portion of that investment surprisingly quickly.
How squirrels damage insulation
Squirrels use loft insulation as raw material for nest building. They'll tear it up, compress it, and drag it into corners to form a drey-like nest, particularly when preparing to give birth. This isn't incidental damage — it's a direct consequence of how squirrels behave once they've established themselves in a roof space, and it tends to worsen the longer an infestation goes unaddressed.
Why compressed or soiled insulation is a real problem
- Compressed insulation loses much of its thermal performance, since insulating value depends heavily on trapped air
- Torn and displaced insulation leaves gaps, creating cold spots and reducing overall efficiency across the loft
- Urine and droppings contaminate insulation, which for hygiene reasons often needs to be removed and replaced rather than simply topped up
- Repeated infestations over successive years can mean insulation needs replacing more than once, adding up in cost over time
The wider cost beyond insulation itself
Damaged insulation typically means a less energy-efficient home, with heat escaping more readily through the roof — a particularly relevant concern for larger Ascot properties where heating costs are already a significant outgoing. Squirrels also frequently gnaw at cabling running through the loft, which is a genuine fire risk and a separate issue that often needs addressing alongside insulation damage.
Protecting your investment
If you've had loft insulation recently installed or upgraded, it's worth having the roof space checked for entry points as a preventative step, particularly if your property has overhanging trees or older soffits and fascias. Catching squirrel activity early, before a nest is fully established, significantly reduces the amount of insulation likely to be affected.
