It's a common and frustrating pattern: squirrels get removed from a Cookham loft, everything goes quiet for a few weeks or months, and then the scratching starts again. When this happens more than once, it's rarely because squirrels have simply had a change of heart — it's almost always because something about the property is still inviting them in.
Cookham's leafy setting, with gardens and boundaries backing onto woodland, hedgerows, and mature trees around areas like Cookham Dean and the approach to Winter Hill, means grey squirrel populations locally are healthy and roof spaces are within easy reach of natural cover. That's the backdrop. The reason they keep choosing your roof specifically usually comes down to a few repeatable causes.
The entry point was never properly closed
The single biggest cause of repeat activity is an entry point that was blocked with something temporary — mesh that wasn't secured, a gap that was covered rather than properly closed, or a repair that addressed one hole while missing a second, less obvious one nearby. Squirrels are strong and persistent gnawers, and a weak repair often gets reopened within weeks.
The scent of a previous nest lingers
If nesting material and droppings weren't fully cleared out after the last squirrel was removed, the residual scent can make the loft attractive to other squirrels in the area, effectively advertising it as a proven nesting site. This is one reason removal and proofing need to be treated as a full process rather than two separate, disconnected steps.
The roof still offers easy access routes
- Overhanging branches or shrubs giving squirrels a direct route onto the roofline
- Gaps around soffits, fascias, or roof tiles that weren't part of the original repair
- Damaged or loose roof tiles creating a new access point over time
- Ridge tiles or valleys that have shifted, creating small but usable gaps
Breaking the cycle for good
Stopping squirrels returning for good means treating the whole roofline as a system rather than patching a single hole. That means finding every current and potential entry point, using materials squirrels can't chew through, removing all nesting material and its scent, and, where relevant, addressing overhanging vegetation that gives easy access to the roof. If squirrels have come back to your Cookham property after previous work, it's worth having the whole roofline reassessed rather than treating it as a repeat of the same isolated problem.
