Wasp Nests Under Roof Tiles – A Common Problem for Shrewsbury Homes
A nest under the tiles gives itself away through the wasps’ comings and goings, and watching those from a safe spot on the ground tells a technician most of what they need.
The tell-tale line in the air
Wasps are creatures of habit. Once a colony has a way into the roof, workers use the same gap again and again, and over a warm afternoon that repetition draws a visible line through the air. Stand in the garden and look up at the roof edge, and you may see wasps arriving in a steady stream, hovering briefly at one spot and vanishing.
The line is more reliable than the sound of buzzing, because sound travels strangely around a house. A hum might seem to come from the chimney when the entrance is actually at the far end of the eaves. Your eyes are the better instrument.
The first few days of noticing are worth using. If you can describe a precise point, such as the third tile along from the gutter on the left, the technician has a head start.
Early morning and late afternoon can be especially useful, because wasps are travelling steadily and the low sun lights up the roof edge. In the middle of a hot day the numbers can seem to thin out, as some workers stay cool inside the nest.
How to watch without getting close
The aim is to observe from a distance that keeps you outside the wasps’ attention. Several metres back is a sensible minimum, and further is better.
- Choose a dry, warm morning or afternoon, when the wasps are active.
- Stand still, with the sun behind you if possible, so you can see against the light of the sky.
- Watch for five or ten minutes rather than a few seconds.
- Count roughly how many wasps arrive in a minute and note whether the numbers rise or fall.
- Keep children and pets indoors while you watch.
If you have binoculars, they let you stay far enough away that the wasps pay you no attention at all.
If you can stand at two points, one on each side of the entrance, you can build up a clearer idea of the angle at which wasps arrive. This is not essential, but it sometimes helps with a roof that has several gables or an extension.
Take a phone photograph of the roofline from your usual viewing point and mark where the traffic goes. It can save a lot of explanation on the phone.
Why this is not a ladder job
The most common mistake with a roof-level nest is to fetch a ladder and take a closer look. A ladder puts you at the height of the nest, with a hand on the rungs and nowhere to go if wasps respond. A swarm at head height on a ladder is a recipe for a fall as well as for stings.
Roofs and the edges of roofs add to the danger. Tiles can be loose, gutters can be brittle and the ground below may be uneven. These are risks even without wasps.
A nest at the top of a house is best left to qualified, fully insured technicians who work at height as part of the job. The treatment is safe and effective, and you stay on the ground.
There is another reason the ground is the right place to be. Tiles can slip, and a ladder resting against a gutter or a fascia board can crack plastic fittings. The damage can end up costing far more than the problem you set out to solve.
Please do not seal the gap
Filling the hole at the roof edge looks like an obvious step. If the wasps cannot get in, the problem should end. In practice the colony is already inside, and workers that cannot leave through the front door look for another exit.
That other exit is often into the house, through a light fitting, a gap around a pipe or a loose hatch. Sealing too soon can therefore turn a nuisance outside into a problem in the bedroom.
Leave the gap open until the nest has been treated and the wasps have gone. Repairs can follow, and a roofer or builder is the right person for them.
It is also worth knowing that wasps do not need a large entrance. A narrow gap between tile and underlay, or beside a bargeboard, is plenty. A tidy-looking roof edge can still hide a large colony.
The fixed price, even at height
One worry people have is that a nest on the roof must cost more than one in a garden. It does not. The price is £80 per nest, fixed, whether the nest is in a shed, a bush or the roofline. There are no hidden fees and nothing is added for the location or the time of day.
A second nest on the same property is £40 flat, and there is no call-out charge. One visit is guaranteed.

Booking, and what happens afterwards
To book, phone 07916 322 280 or use the online form on the contact page. Give the address, describe where you have watched the wasps entering and say whether anyone is allergic to stings, so the booking can be prioritised. Evening and weekend appointments are available.
After treatment, wasps still in the roof will gradually stop. Some dead ones may fall into the gutter or onto the ground below, and a few may wander indoors. Sweep them up and put them in a sealed bag.
Ask at booking whether the empty nest can be taken down. Once activity has stopped, a roofer can check and repair the gap.
If you live in a terrace or a pair of semis, mention it when you book and say which side the wasps appear to favour. The technician can then plan where to stand.
