Grey squirrels are remarkably capable climbers and chewers, and a roof space that looks secure at ground level can still have several weak points a squirrel is happy to exploit. Understanding how they actually get in helps explain why squirrel problems keep recurring in some Theale properties even after a clear-out.
The usual entry points
- Gaps where soffit boards meet fascias, especially where wood has warped or rotted slightly
- Loose or missing roof tiles, particularly around ridges and valleys
- Gaps around gable end vents or damaged mesh covers
- Openings around chimneys where flashing has lifted
- Damaged or poorly fitted felt at the roof edge
- Existing holes left by previous pest activity that are never properly sealed
Why squirrels can exploit such small gaps
A grey squirrel can squeeze through a gap not much bigger than a couple of inches across, and their front teeth grow continuously, which gives them both the motivation and the ability to gnaw softened or rotten timber wider until it's big enough to pass through. Once one squirrel has created a route in and out, the enlarged gap and the scent left behind often attracts others.
Trees, fences and roof proximity
Access isn't only about the state of the roof itself - it's also about how easily a squirrel can reach it. Overhanging tree branches, tall fence panels close to the eaves, and even drainpipes running up to roof level all give squirrels a route from the ground or a neighbouring garden straight onto the roofline. This is a particularly common factor on the tree-lined streets around Theale, where mature gardens back onto woodland or green space.
Older properties versus newer builds
Period properties in and around Theale often have timber soffits and fascias that have weathered over decades, giving squirrels softer material to work with. Newer builds aren't immune either - poorly sealed vents, gaps left during construction, or minor settlement around roofline joints can all create an opening if left unchecked.
