Almost everybody who describes this says the same thing: it sounds far too big to be a squirrel.
There is a good structural reason for that, and once you know it the noise becomes a genuinely useful diagnostic rather than just an alarming one.
Why it sounds so large
A grey squirrel weighs around half a kilogram. What it is landing on is a ceiling — a thin plasterboard membrane stretched across joists with an air void above it and a room below. That is a drum. A half-kilogram animal landing on a drum from a joist is genuinely loud, and the sound arrives in the room amplified rather than muffled.
The five noises
- Thumping. Landing after a jump between joists. The one that makes people sit up in bed
- Running. Short, fast, purposeful bursts that stop dead rather than tailing off
- Rolling. Something being moved — a cached nut, a piece of debris — which sounds oddly like a marble and confuses everybody
- Gnawing. Coarse, rhythmic and much heavier than a mouse. Often the longest single stretch of noise
- Dragging. Nesting material being hauled about, mostly in autumn and before breeding
Reading the timing
This is the part worth acting on. Grey squirrels are diurnal: they are out and about in daylight and quiet overnight. So the noise clusters into two peaks — roughly the first two hours after first light, and again in the late afternoon before they settle.
That pattern is very hard to mistake for anything else. Rats and mice run at night and go quiet as the house wakes up. Birds are confined to the eaves and are loudest in spring. A jackdaw in a chimney is a scrabbling, echoing noise in a flue rather than a hollow one overhead.
Write the times down for three days. Time of day, roughly how long, and which room it is above. That short list settles the species and the elevation before anybody arrives, and it costs nothing.
Where the noise is coming from
Sound travels along joists and through cavities, so the room you hear it in is not always the part of the roof it is happening in. In a terrace it can genuinely be a neighbouring roof space. Two checks help: whether it is always above the same room, and whether the loudest point is near an outside wall, which is where the entry usually is.
Noises that are not an animal at all
- Water pipes ticking as they warm and cool — regular, and tied to heating times
- Roof timbers expanding on a sunny afternoon — single cracks, not movement
- Loose aerial cable or a lifted tile in wind — only in weather
- A ball valve or tank refilling — tied to taps and toilets
Questions
Could one squirrel really make that much noise?
Yes. It is the commonest thing people find hard to believe, and the ceiling is the reason.
Why does it stop for days and then start again?
A roof space is a resting site rather than a residence. Activity follows weather, food and the season, so gaps of several days mean very little.
Is high-pitched squeaking a squirrel?
It can be young, typically in spring or late summer. It is worth mentioning when you call, because it changes the timing of the work.
