Squirrels aren't just noisy loft guests - left in place, they can cause genuine, sometimes costly damage to a property. We regularly assess this kind of damage in Pangbourne homes, and it tends to fall into a few consistent categories, some far more serious than others. Structural timber, electrical cabling, insulation and roof weatherproofing can all be affected, often at the same time.
Structural and Timber Damage
- Gnawed roof joists, rafters and trusses, which can weaken timber over time
- Enlarged entry points around soffits, fascias and roof tiles, letting in further wildlife and weather
- Damage to loft boarding and stored timber items from continuous gnawing
- Chewed skirting or roofline trim where squirrels have tested for further access
Electrical Risk
This is the most serious category. Squirrels gnaw to keep their continuously growing teeth in check, and electrical cable sheathing is an unfortunately convenient target. Exposed or damaged wiring in a loft space is a genuine fire risk, and because it's often hidden under insulation or behind boarding, it can go unnoticed until it causes a fault or, in the worst cases, a fire.
Insulation, Energy Efficiency and Water Ingress
Squirrels shred and displace loft insulation to build nests, reducing its thermal performance and potentially increasing heating costs, with soiled or compacted insulation also raising hygiene concerns in lofts used for storage. On top of this, enlarged entry points and damaged roofline materials let weather in as well as squirrels - once a gap has been gnawed open, rain can track into the roof space, leading to damp, ceiling staining, and further deterioration of timber and insulation over time.
Squirrel damage tends to compound the longer it's left unaddressed - a small gnawed gap becomes a larger entry hole, a small patch of disturbed insulation becomes a fully stripped area, and minor cable damage becomes a genuine electrical hazard. Early inspection tends to mean a smaller, simpler repair job, so if you suspect squirrels are active in your Pangbourne property, it's worth having the roof space checked before the damage progresses.
