About our electronic leak detection in Old Chiswick
You get a report showing the location of each breach with photos. Your roofer can then repair those points instead of hunting for the leak. Repair costs are not part of the report, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. If you are worried about a flat roof leak that can’t be traced and damp inside with no sign on the roof, a survey will tell you what’s going on, on flat roof membranes, green roofs and commercial flat roofs alike.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Old Chiswick, the flat roof is often a shared part of the building.
Findings are set out part by part, from the main slopes down to the gutters and outlets. It records what’s sound as well as what is not.

Local flat roofs in Old Chiswick
Within a mile and a half or so of Old Chiswick there are several hotels, and like offices and blocks, hotels often sit under flat roofs. If you look after one, a leak through a flat roof can put a room out of use. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
For hotels and guest houses around Old Chiswick, a roof problem found early is far less disruptive than one found by a guest. If you live in an older home near St. Nicholas Church, the joins between later flat roofs and the old walls are where problems normally start.

What we do, step by step
A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. For a visit in Old Chiswick, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from the ground, windows, the loft and, where it’s safe, the roof itself.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- 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
- Check pets are kept safely away
- Have any paperwork from past roof work to hand
- Let us know about parking before the day

When to book a survey in Old Chiswick
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
Things that frequently lead to a survey include:
- New membranes needing a check before handover
- Stains far from any visible defect
- Water coming in under a flat roof
- Leaking laps in the waterproofing
If you look after a building such as The William Hogarth Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
Choosing a roof surveyor
- Which parts of the roof they’ll actually see

Questions from Old Chiswick
Is my home in Old Chiswick listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Can parking be tricky for a visit in Old Chiswick?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
When does the report arrive?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline when you book.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first. Mention it when you contact us and we’ll explain what’s needed.
Do you cover Old Chiswick for electronic leak detection?
Yes. We survey roofs in Old Chiswick and the rest of Greater London, as part of our work across London and South East England. To book, phone 07833 053749 or use the contact form.
Can you survey at the weekend?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just tell us the days that suit you.
Does the weather affect the survey?
It depends on the weather and the survey. In strong wind or heavy rain, a drone cannot fly and access may not be safe, and we’d agree another day.
What affects the cost of electronic leak detection
We confirm the exact price before booking. This is what makes a difference:
- The size of the roof
- The height of the building and how the roof can be seen safely
- Any need for thermal images or a drone flight
- The shape of the roof and its details
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You’ll know the price for your survey before you book.
Booking your survey
There’s no need for technical words. Just tell us:
- Pictures of the roof from a safe spot, if you have them
- What’s prompted the survey
- How the loft is reached, if there is one
- Where any leaks, stains or damp patches show inside
Most bookings start with a short call: ring 07833 053749 or email us, and we will ask about the building and what you need. The price is agreed before a date is set.
