Electronic leak detection for homes and businesses in Caldecott
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. We’ll tell you if the roof can’t be tested. If you’ve noticed breaches around outlets and penetrations and leaking laps in the waterproofing, we can find out what’s behind it, whatever the roof.
In a smaller place like Caldecott, some flat roofs sit in the open, where wind can catch loose edges and trims. Felt and bitumen also age in strong sun. The signs are splits, blisters and edges coming away, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
After the visit, you get a report with photographs, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Leave it or get it looked at?
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. Around Caldecott, a leak in an older house can soak into timbers and plaster, and that is a much bigger job than the original defect.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

No survey can tell you everything, and we’d rather be clear about that before booking. Keep these in mind:
- Roofs whose membrane or build-up is not suitable
- Carrying out the repair work

Questions from Caldecott
Is Caldecott within the area you cover?
Yes, Caldecott is covered. We cover the whole of London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you look at commercial flat roofs near Caldecott, like hotels?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you’ll get a quote based on the building, and roof access is agreed with you before the visit.
What happens next?
You’ll receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
How much does electronic leak detection cost?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. For a quote, ring 07833 053749 or drop us an email.
Do I have to be there for the survey?
Not always. If we only need the outside, we can agree that beforehand, but anything inside needs someone there to give access.
Does the report include photos?
Yes, plenty. Pictures sit next to the findings they show, which makes the report easy to follow.

Useful tips for Caldecott property owners
Small things make a difference. Our tips:
- Share any drawings of the roof
- Keep outlets clear of debris
- Keep a note of leaks after rain
- Do not keep patching the same spot
Wet insulation may need attention after a leak. Your roofer can advise on that and other checks can help judge it.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.
The survey, step by step
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. The inspection then takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. With a bit of garden around a house, as there often is around Caldecott, the roof can be viewed from several angles. Let us know if any side is fenced off or hard to reach. Inside, the loft is looked at where it can be reached safely.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Getting ready for the survey
- Let us know about parking near the property
- Make a note of anything you’d like us to look at
- Keep pets out of the way during the survey

What we look for on each type of roof

ELD on EPDM depends on the product and the layers. We check before we quote.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible but it depends on the layers.
Local flat roofs in Caldecott
Cotswold stone slates are found on older buildings in west Oxfordshire, and thatch survives in some of the county’s villages. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Clifton Hampden Manor, about 3.5 miles east, is one of the historic houses in the wider area around Caldecott. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
If you look after a building such as Thameside Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. A roof leak in a hotel or guest house around Caldecott means lost rooms as well as repairs, so it is worth knowing the roof’s condition. For an older house near a landmark like St Helen's Church, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
