Bird proofing, eaves & pest exclusion
In short
Birds, squirrels and wasps get into a roof through gaps at the eaves, under loose ridge tiles or through rotten soffits. Proofing means closing the actual entry points properly, at the right time of year, and repairing whatever let them in.
Also called: Birds in the roof · Birds nesting under tiles · Squirrels in loft · Eaves protection
Signs you need this
- Scratching, scrabbling or birdsong from the loft or eaves
- Birds repeatedly disappearing under the tiles at eaves level
- Droppings on a windowsill, path or flat roof below the eaves
- Chewed or holed soffit and fascia boards
- Nesting material visible in a gutter or valley
- Wasps entering at a consistent point in the eaves
Anything living in a roof got there through a gap, and the gap is usually a defect rather than a design feature. Rotten soffit boards, a broken eaves comb, a missing tile, a loose ridge or a gap where a verge has lost its mortar — all of them are roofing faults first and pest entry points second.
That is the important framing, because closing the hole without fixing the reason it is there is a temporary measure. A soffit that squirrels chewed through was soft because it had been wet for years; blocking the hole in soft timber lasts until they try again a foot along.
Timing is a legal matter and not a preference. All wild birds, their active nests and their eggs are protected under the Wildlife and Countryside Act 1981, and it is an offence to intentionally damage or destroy a nest while it is in use or being built. In practice that means proofing work happens outside the nesting season, and where an active nest is found the work waits. A roofer who offers to clear an occupied nest in May is offering to break the law on your behalf.
The commonest entrants have their own patterns. Starlings and sparrows get under loose tiles at the eaves and into the roof space. Pigeons roost on flat areas and in valleys and make a considerable mess that blocks outlets. Squirrels chew through soffit boards and fascias and are much more destructive once inside, because they will take on cabling. Wasps build in lofts and under eaves and are best left to a pest controller before any roofing work starts.
Proofing done properly is a repair rather than a netting job. Eaves combs and filler units close the gap between the tiles and the fascia — the gap that exists on every tiled roof and that many houses have lost. Rotten soffits and fascias get replaced rather than patched. Loose ridge and verge units get refixed. Where netting or mesh is genuinely needed, on a flat area or a valley that pigeons use, it is fitted so it does not itself trap water or debris.
One important caveat: proofing must not block the ventilation. Sealing the eaves to keep birds out, without providing a ventilation path, converts a bird problem into a condensation problem. Eaves combs and vented soffit systems are designed to do both — exclude the wildlife and keep the airflow — which is why the right product matters.
What the job covers
- Entry points identified rather than guessed at
- The underlying defect repaired — rotten timber, loose units
- Eaves combs and filler units fitted to close the tile gap
- Ventilation maintained while excluding wildlife
- Work timed to respect the bird nesting season and the law
- Referral to a pest controller where wasps or an infestation are present
What it costs
We don't publish a price for this yet, because a number pulled out of the air is worse than no number at all — your roofer has to honour it. On roofing it would also be close to meaningless: access is often the biggest single factor, and it varies enormously house to house. You'll get a firm price for your actual job when they ring you back, before any work starts. The quote itself is free and there's no obligation either way.
Common questions
There are birds nesting in my roof. Can you remove them?
Not while the nest is active. All wild birds, their eggs and their nests in use are protected under the Wildlife and Countryside Act 1981, so proofing work waits until the nest is finished with. Anyone offering to clear an occupied nest in the middle of the season is offering to break the law for you.
When can proofing be done?
Outside the nesting season, once any nest is no longer in use — in practice usually late summer through to early spring, and it depends on the species. That is also the sensible time for the roofing repairs that go with it, since the entry point is nearly always a defect that needs fixing anyway.
Will sealing the eaves cause condensation?
It will if it is done with the wrong product. The eaves are where the roof gets its ventilation, so blocking them solid converts a bird problem into a damp loft. Eaves combs and vented systems exclude wildlife while keeping the air path open, which is exactly why the product choice matters.
Squirrels have got into my loft. What now?
Get the animals dealt with by a pest controller first, then the entry points. Squirrels chew through soft soffit and fascia timber and will damage cabling once inside, so it is worth acting promptly. The roofing part of the job is replacing the timber they got through rather than patching it, because they will simply go through the soft board again.
