Electronic leak detection in Dorney, Windsor and Maidenhead
We take a careful look at the flat roof membrane at your property in Dorney, with photos and a written report.
- Breaches hidden under paving or planting
- Leaks at pipes, outlets or fixings
- Failed seams and laps
How the survey changes by roof type
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane, which affects testing.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Electronic leak detection in Dorney
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing will not show on the test. We’ll tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. You’ll also know what to check next. If you’ve noticed stains far from any visible defect and leaking laps in the waterproofing, we can find out what’s behind it.
Older buildings in small places like Dorney may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
The report works through the roof section by section, from the coverings down to the gutters, each with a short note and a photo. You’ll see the good as well as the bad.

What else we do in Dorney
The survey, step by step
We check the roof from outside and, where it is relevant and there is safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement. The whole visit usually takes a length of time set by the roof’s area and construction, which we’ll explain when we quote. In a hamlet or village like Dorney, a postcode doesn’t always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
How to prepare
- If it is not your property yet, arrange access through the agent
- Keep pets in another room
- Gather any invoices or paperwork from past roof work

If you’re not sure which survey you need, ring 07833 053749 or email us and we’ll give you a straight answer before booking. What our survey covers.
What we check
- Roof terraces and balconies
- Commercial flat roofs
- Single-ply roofs
- Flat roof membranes
- Green roofs
- Liquid-applied waterproofing
Tips from our surveys
Over many surveys, some simple habits stand out as worth the effort:
- Have roof specifications to hand
- Test new membranes before covering them
- Record dates and spots where water appears
- Act on new leaks promptly
Where the evidence points to walls, copings or rooflights, we’ll note it, with a suggestion of what to check next.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
Signs you need electronic leak detection in Dorney
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
A survey can pick up problems like:
- Failed seams and laps
- Damp inside with no sign on the roof
- Punctures from foot traffic or tools
- Leaks through a flat roof with no obvious cause
Landlords with a home close to Burnham station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
What to check before booking
- Whether you get a written report with photos
- Whether the loft is part of the inspection
- Their report turnaround times
- What’s outside the scope of the survey
What happens if roof problems are left?
A visual inspection can miss tiny holes. Electronic testing can find breaches you can’t see by eye where the roof suits it. Older and listed buildings around Dorney may need consent and matching materials for repairs, so leaving a defect until it is urgent leaves less time to plan.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your survey before booking.

Electronic leak detection around Dorney
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. The wider area around Dorney has a long history of building, with Dorney Court about 0.5 miles west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
Anyone responsible for a site like Western House Academy will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. If you live in an older home near Church of St James, the flat roofs on later extensions tend to wear out long before the main roof.

FAQs for Dorney
Does a conservation area affect roof work in Dorney?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you cover Dorney?
Yes, Dorney is within the area we cover. We cover the whole of London and South East England. You can call 07833 053749 or drop us an email with the address and some details.
Can you survey in bad weather?
Light rain does not typically stop a survey, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so if conditions aren’t right we will arrange another day with you.
Can you test a green or ballasted roof?
In some cases. The layers on top and the build-up below decide it, and some may need lifting. We talk this through first.
How long will testing take?
The roof’s size and build-up decide how long it takes. You will know roughly how long before we start.
Is it a structural engineer’s report?
No. We point out what can be seen, such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Is this an asbestos survey?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings.
