Honey bees in roof spaces.

When someone reports bees “in the roof”, the colony is rarely in the open roof space itself. More commonly, bees entering beneath tiles are occupying a cavity wall behind the roofline, an old dismantled chimney stack hidden beneath the tiles, a soffit void, or the space within a dormer structure.
True roof space colonies – where bees are building comb in an open loft – are less common than most people expect. But they do happen, and when they do the removal requires careful access to avoid unnecessary damage.
We use thermal imaging to locate the colony before starting any work. This removes guesswork and ensures we access the right void first time.

If Bees Are Getting Into Your Home Through Light Fittings

Bees entering through light fittings indicates the colony is in a ceiling void or between floors. This is a common scenario in flat roofs and dormer structures where the void provides the enclosed space bees need.

Where Bees Actually Nest in “Roof” Scenarios

Cavity walls behind the roofline:

Bees entering beneath tiles near the eaves are often occupying the cavity wall. The roof provides shelter to the entry point but the colony is in the wall void below.

Dismantled chimney stacks:

Old chimney stacks that have been taken down to below roofline level but left in place beneath the tiles are a common nesting site. The bees enter through gaps in the tiles and occupy the void where the chimney used to be.

Soffit and fascia voids:

The void behind soffits or between fascia boards and the wall provides an enclosed space bees will readily occupy. Entry is typically through gaps where the soffit meets the wall or through ventilation slots.

Dormer structures:

Dormers create voids where the two roof planes meet. Bees entering at this junction are usually occupying the dormer roof space. This is one of the more predictable roof scenarios.

Flat roof voids:

Flat roofs with a void between the ceiling and the roof membrane – common in extensions and commercial buildings – provide ideal nesting space. Bees often occupy the space between rafters.

Open loft spaces:

Less common but it does happen. Bees entering through roof damage or ventilation points may build comb suspended from rafters in an open loft. This is the easiest scenario for access and removal.

How We Remove Bees From Roofs

External access – our preferred method where practical:

We temporarily remove roof tiles or slates, cut through the membrane (which is often deteriorated in these scenarios), and remove all the bees, comb and honey stores from above. The bees are relocated to our apiary.

This is usually more straightforward for reinstatement than accessing through ceiling plasterboard. It’s also more comfortable to work from – as opposed to working inside a hot enclosed space, reaching into a hole above your head, with wet sticky honey ready to fall along with thousands of bees.

Before reinstating the tiles or slates we clean the area as much as possible, scraping off honey and wax residue.

Dormers:
For dormer structures we usually access from within the property rather than removing external roofing, to save on the cost of complex scaffolding.

Internal access – sometimes necessary:

For some roof configurations, internal access through the ceiling is more practical. This depends on the structure, the location of the colony, and what access route causes least disruption overall. Typically this includes flat roofs and dormers.

Thermal imaging:

We use thermal imaging to locate the colony before starting work. This tells us where the bees actually are, how far the colony extends, and what access route makes most sense. It removes guesswork and prevents opening the wrong void.

Access costs:

Scaffold or Mobile Aluminum Tower is quoted separately where required. Best route of access is usually identified and indicated when we get back to you with pricing.

Proofing Roofs After Removal

What can realistically be proofed:

Specific entry points can be addressed – dormer junctions can be sealed, soffit gaps can be meshed or filled, damaged tiles can be replaced, dismantled chimney voids can be sealed.

What cannot practically be proofed:

An entire old tiled or slated roof cannot be proofed against all possible bee entry points. There are too many potential gaps and any attempt to seal them all would require work disproportionate to the problem and risk creating ventilation issues.
What can be done is to reduce the likelihood of reoccurrence by addressing the specific entry point used and making the space less attractive or accessible.

The ventilation issue:

Roof voids, soffits and ceiling spaces need airflow to prevent condensation and moisture buildup. Filling these voids densely with insulation material – which we see attempted – creates damp problems and can lead to wood rot.
Air vents, weep holes and air gaps exist for good reason and should not be sealed or blocked. We have developed proofing solutions that address bee entry without compromising building ventilation. We discuss options on site once we’ve seen the structure.

On guarantees:

No one can offer a genuine guarantee that bees won’t reoccupy a roof space. If someone offers one, read the small print – you’ll find get-out clauses that make it far less comprehensive than it sounds. See our Proofing & Guarantees page for full detail on why most bee removal guarantees aren’t worth having.

Pricing

Cost depends on how long the colony has been established, the roof configuration, what access is required, and whether the work can be completed from outside or requires internal access through ceilings.
We provide a cost indication once we understand your specific situation – photos, location, and details of where the bees are entering. We rarely need a site visit to provide an accurate cost indication.
Most roof removals are priced on a day rate basis. The job is typically completed within one day, though reinstatement may extend into a second day depending on the extent of proofing required.
Access costs are quoted separately when required.
