About our electronic leak detection in High Cogges
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. The results come in a report with photos. If you’ve noticed water coming in under a flat roof and holes around roof penetrations, a survey will tell you what’s going on, whatever the roof.
Some older homes in villages like High Cogges are listed or in a conservation area, which can shape what a new flat roof may look like. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Useful tips for High Cogges property owners
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Do not keep patching the same spot
- Test new membranes before covering them
- Act on new leaks promptly
- Clear flat roof outlets regularly
You receive a report showing where each breach was found, with photographs. Your roofer uses it to carry out repairs.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.

For landlords and managing agents
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Tell us about it when you book and we will plan the survey around it.
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
Electronic leak detection in High Cogges: local notes
Minster Lovell Hall, about 3.6 miles north-west, is one of the historic houses in the wider area around High Cogges. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
Hotels and guest houses near High Cogges can’t easily close rooms for a leak, so it pays to find faults before guests do. For an older house near a landmark like Church of St James, the flat roofs on later extensions tend to wear out long before the main roof.

FAQs for High Cogges
Do you look at commercial flat roofs near High Cogges, such as hotels?
Yes, commercial buildings, hotels included, are part of the work. Access to the roof is sorted out with whoever manages the building before the day.
Is my home in High Cogges listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
What is electronic leak detection?
The waterproofing membrane normally stops an electrical current, so wherever there is a hole, it passes through. That lets us find breaches that are too small to see.
Will you check the loft?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps.
What happens after the survey?
You will receive the report by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
How quickly is the report sent?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
