Electronic leak detection in Dedworth
Our ELD testing covers flat roofs in Dedworth and the rest of London and South East England. A visit typically takes a time that depends on the roof’s area and construction, which we’ll explain when we quote. Every roof is quoted on its size and build-up. You get a report with photos. If you’re worried about new membranes needing a check before handover and stains far from any visible defect, a survey will tell you what’s going on, whatever the roof.
Flat roofs in smaller places like Dedworth can be more exposed, especially where nothing shelters them, 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. A flat roof that still holds water days after rain is also worth a closer look.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

What electronic leak detection looks like in Dedworth
Historic houses such as St Leonard's Hill, about 0.6 miles south, show how far back building in the area around Dedworth goes. 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. Within a mile and a half or so of Dedworth there are several hotels, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
For landlords with property near Windsor & Eton Central station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If yours is one of the older homes in the streets near All Saints Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. For site and facilities teams at buildings like Dedworth Green First School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

What else we do in Dedworth
Why act early in Dedworth
Not every leak is in the membrane. Testing shows whether the membrane is breached, so other causes can be checked. Around Dedworth, a leak in an older house can soak into timbers and plaster, which is far harder to put right than the roof fault itself.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.
Why book with us
- Independent findings on the roof’s condition
- Two decades and more of roof surveys
- A written report with photos

Your questions about electronic leak detection in Dedworth
Do you cover commercial flat roofs around Dedworth?
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 Dedworth listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
What is electronic leak detection?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That lets us find breaches that are too small to see.
What do I do with the report?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Will you walk on the roof?
Only if it’s safe. We check everything that can safely be seen: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where applicable. The report says if anything couldn’t be seen.
Do you look in the loft space?
Yes, where the survey calls for it and there’s safe access. We look for staining, damp, daylight and signs of movement, as far as the space allows.
Is the repair part of the test?
No. We test the membrane and report. You get the breach locations with photos for your roofer to repair.
How it works
The visit usually starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes as long as needed for the roof’s area and construction, which we set out in the quote. Some parts of a survey depend on the weather, so a visit to Dedworth is booked with the forecast in mind: drone flights and thermal imaging need the right conditions, while a look from the ground and the loft can go ahead in most weather.

Related advice
How the survey changes by roof type
Bituminous membranes
ELD is frequently possible on bituminous membranes, depending on what’s below.
Green and ballasted roofs
Some layers may need lifting for testing. We discuss this before quoting.
Rented homes, blocks and businesses
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Bigger roofs take more time.
What you can safely check yourself
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
