Wasp Nests Under Roof Tiles – A Common Problem for Guston Homes
A nest in the roof one summer often leads to a worry about the next. A simple check each spring from the ground can catch gaps before wasps do.
Why people ask about next year
Having dealt with a roof nest once, most householders want to know it will not come back. That is a sensible wish, and it comes with a sensible answer. The nest itself is finished once the season ends, but the gap that let the wasps in is still there unless somebody has mended it.
A wasp looking for a place in spring is not returning to an old home; it is looking for a good gap. If yours is still open, or there is another like it, a wasp may find it.
In Guston, as in any other place, a little routine each year costs less than a repeat of the summer.
The seasons help here. Wasps come out of hiding as the weather warms, so the weeks before late April are the quiet window in which to check the roof and make any repairs.
The ten-minute check in April
Choose a dry, bright day in April, before the wasps are active. Walk slowly around the outside of the house and look at the roofline from a few metres out. You do not need to climb or touch anything.
- Look along each side of the roof for tiles that are out of line, cracked or missing.
- Check the ridge and the hips for gaps in the mortar.
- Run your eye along the fascia and soffit boards for holes, cracks or loose joints.
- Look at the junctions with chimneys, dormers, porches and extensions.
- Photograph anything doubtful and list it for a roofer.
If you spot wasps already using a gap in April or May, do not interfere. Note it and arrange a treatment.
Take a notebook or your phone. A few photographs of the roof in April become a useful comparison next year, and they show a roofer exactly which tiles you were worried about.
What counts as a gap
Wasps need very little space. A hole the width of a finger will do, and a crack that looks closed from the ground may be open enough from a wasp's point of view. Do not be put off by how small the problem looks.
The usual culprits are slipped tiles, crumbled mortar, shrunk or warped boards, worn vent covers and gaps where pipes pass through the eaves. Older roofs have more of these, but newer ones are not immune.
The best repair is one made by a roofer or carpenter with the right materials, and done after any nest has been treated.
If your roof has been repaired recently, check the repair too. A new bit of lead or a freshly bedded ridge can still have a small crack along its edge.
Repairs in the right order
If a nest has used a gap, wait until it has been treated and the wasps have gone. Repairing sooner risks trapping the colony. Repairing later than April risks missing the spring window.
A tidy-up in the autumn after a nest has gone, or in early spring before wasps start flying, is the ideal moment. The wasps are absent, the weather is dry enough for roof work and the gap is closed before it is needed.
Ask the roofer to check the neighbouring boards and tiles while they are there, since one gap is often a sign of more.
If a gap is too high for you to be sure about, binoculars will tell you most of what you need. Do not climb up just for a better view.
Mesh over vents and a good seal at the soffit are the commonest improvements, and both are quick jobs for a competent carpenter.
What not to rely on
There are plenty of products and tricks on sale that claim to keep wasps away from a house. Fake nests, plug-in devices and scented sprays have no dependable effect on a wasp that has found a good gap.
Some people also hope that treating a nest will protect them from the next one. It will not; the treatment deals with the colony that is there, not with future arrivals. The real protection is a sound roof.
In the case of a sting, wash the skin gently, take out the sting if you can see it and apply a cold pack. Treat it as an emergency and call 999 if there is swelling of the face, lips or throat, or a wheeze or trouble breathing, or if dizziness or a widespread rash develops.
Be sceptical of anyone who offers a guaranteed wasp-proof roof. A well-kept roofline reduces the chance of a nest, but it cannot be absolute.
Price, booking and a plan for the year
The fee for one nest is a fixed £120 per nest, with no extra for attending. If a second nest is found at the property, it is simply £60 extra. On the price graphic, you are promised one visit guaranteed, and no sum is added for a repeat customer or a busy season.
If wasps do return, ring 01622 410 019 or use the booking form on the contact page, which also takes emergency requests out of hours. Bookings run all week, with same-day visits and evening and weekend slots, for domestic and commercial premises. Insurance and qualifications are in place for every visit.
Diary the check for April each year, and book a roofer for any repairs in the autumn. It is a small habit with a large reward.
If your property is rented, send the landlord or agent a note about any gaps you notice. Who arranges and pays for repairs depends on the tenancy agreement.
A plan made now is worth more than a scramble in August: note the April check in the diary, keep the roofer's number handy and keep this year's photographs where you can find them.
