What this survey cannot tell you

- Fixing the holes we find
- The extent of water in the insulation
- Leaks from plumbing or windows

Electronic leak detection in Turnham Green
Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. We’ll say if ELD won’t work on your roof before any testing. Any details you have about the membrane and build-up help us decide, including drawings, specifications or the roofer’s paperwork. It avoids arranging a test that can’t give results. We survey commercial flat roofs, flat roof membranes and single-ply roofs, and common reasons people get in touch are leaks through a covered membrane and leaks at pipes, outlets or fixings.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. Which one is on a roof in Turnham Green shapes how it is checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Flat and commercial roofs around Turnham Green
The wider area around Turnham Green has a long history of building, with Hogarth's House about 0.2 miles west. 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. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Turnham Green is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If your house is among the older ones in the streets near St. Nicholas Church, the flat roofs on later extensions tend to wear out long before the main roof. A roof leak in a hotel or guest house around Turnham Green means lost rooms as well as repairs.

Turnham Green questions
Can you look at the flat roof of a hotel or office near Turnham Green?
Yes, we cover commercial roofs as well as homes. Access to the roof is sorted out with whoever manages the building before the day.
How do I find out if my home in Turnham Green is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
How much does electronic leak detection cost?
We quote for each roof individually. Let us know about the roof and where it leaks. Just call 07833 053749 or send us an email for a quote.
How does ELD work?
A sound membrane blocks the test current, so wherever there’s a hole, it passes through. That is how we locate breaches you cannot see.
Is it a structural engineer’s report?
No. We are roof surveyors, not structural engineers, and it does not include calculations. We will recommend an engineer if we see signs that call for one.
Will I get photos?
Yes. We photograph the roof as we go, and the report uses them to show each finding alongside our recommendations.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
How it works
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. You are welcome to ask questions while we’re there. In a London conversion, the way into the loft space is often from a communal landing or the top flat. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- You tell us 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.
- A report with photographs shows where each breach is.
How to prepare
- Make sure the loft hatch can be reached
- If you are buying, let the agent know when we’re coming
- Jot down any questions you want answered

Advice
Can I check my roof myself?
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey, using safe viewpoints and a drone where it applies.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
How the survey changes by roof type
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check before we quote.
What a survey costs
Not every roof costs the same to survey, for these reasons:
- Features like valleys, chimneys, dormers and parapets
- Extensions, dormers and garages with roofs of their own
- The height of the building and how the roof can safely be seen
- The type of building, from a house to a block or an office
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for the job before you book.
Booking your survey
Getting the details right at the start saves time. Please include:
- Your postcode, so we can check access and travel
- Access details, like a loft hatch or a shared roof
- Where water is showing inside, if it is
- Dates you’re working to, like exchange
To book a survey, ring 07833 053749 or send us an email with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.
Do you need electronic leak detection in Turnham Green?
On a flat roof, water spreads under the waterproofing. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
A survey can pick up problems such as:
- Water coming in under a flat roof
- New roofs to check before paving or planting
- Leaks that return after repairs
- Damage from equipment installers
Landlords with a home close to Chiswick station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Before booking any roof surveyor
- Which limits apply to the survey
- What insurance they carry
- Will they check the loft as well as the outside?
- Whether you get a written report with photos
