Soffits — the boards running under the roofline overhang, connecting the fascia to the wall — are one of the single most common places we find squirrel entry points on Henley-on-Thames properties. They're often overlooked during general home maintenance simply because they're not visible from ground level without looking up carefully.
Why Soffits Are So Vulnerable
Soffits are typically made from timber or PVC and are fitted with ventilation gaps or grilles to allow the roof space to breathe. Those ventilation points are exactly what a squirrel is drawn to investigate, and where the material has weakened — through age, damp, or a poorly fitted joint — it doesn't take much gnawing for a squirrel to turn a small vent gap into an entry hole large enough to fit through.
How Squirrels Exploit Soffit Weaknesses
- Chewing through plastic soffit vent covers, which offer little resistance once cracked or aged
- Widening gaps at the joints where soffit boards meet, particularly box-end joints at the corners of a roof
- Exploiting timber soffits that have started to rot or delaminate from prolonged damp
- Using downpipes, wall climbers or overhanging branches to reach the soffit level in the first place
What Effective Proofing Involves
Proper soffit proofing isn't just about blocking the specific hole a squirrel has already made — a squirrel that's found one weak point will often test others nearby if the area isn't addressed properly. Effective work usually involves fitting durable mesh behind ventilation points so airflow is preserved but access is blocked, repairing or replacing any soffit sections that have deteriorated, and checking the full run of soffit and fascia around the property rather than just the confirmed entry point.
Don't Just Seal and Walk Away
One mistake we see fairly often is a gap being sealed before it's confirmed the loft is actually clear. If a squirrel is trapped inside when a soffit is sealed, it will cause considerably more damage trying to get back out, and in the case of a nursing female, young squirrels left behind is a welfare and nuisance problem in its own right. Confirming the loft is clear before final proofing is a basic but important step.
