How electronic leak detection works in Hanworth
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye, so your roofer can repair them. You get a report with photos of each breach found. We survey commercial flat roofs, roof terraces and balconies and flat roof membranes, and people most often book us about leaks that return after repairs and damage from equipment installers.
In a smaller place like Hanworth, 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. Standing water that lingers for days after rain is another sign worth watching for.
What you get is a clear record of the flat roof membrane on the day we saw it. It is useful right away, and a good reference for later.

What affects the cost of electronic leak detection
Prices always include VAT. The things that change the price are:
- Any need for thermal images or a drone flight
- Roof area
- Chimneys, valleys, parapets and other details
- How tall the building is and how easy the roof is to see
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the price for the job before booking.
Getting in touch
We will normally ask about:
- Photos of the roof, taken safely from ground level or a window
- Where the property is, with the postcode
- The style of property, from a terrace to a block
- Why you want a survey: buying, a leak, a storm or new work
A quick phone call is typically the easiest start: phone 07833 053749 or drop us an email. You will have a price before anything is arranged.

Hanworth questions
Is my home in Hanworth listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Should a flat-roofed garage or porch in Hanworth be checked too?
Usually, yes: let us know about it when booking so the visit can include it. Flat-roofed garages and porches are common in new towns like Bracknell, and older felt coverings may be near the end of their life.
How soon will I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
Will you repair the leak?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
What insurance do you have?
Our cover is professional indemnity plus public liability, and details are available on request.
What if it rains on the day?
Light rain doesn’t usually stop a survey. High wind or heavy rain can stop drone flights and make roof access unsafe, so we will agree a new date if the weather isn’t suitable.
How experienced are you?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and South East England.
Local flat roofs in Hanworth
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. Hanworth is part of Bracknell, one of the post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Flat-roofed garages, porches and extensions from that era may have been re-covered more than once, or not at all. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check them before they’re disturbed.
For an older house near a landmark such as St Michael and St Mary Magdalene's Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Anyone responsible for a site like The Pines School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you run a business near The Lexicon, a flat roof over a business is out of sight and out of mind until it leaks.

What we can’t see
To be straight with you, a roof survey has limits:
- The extent of water in the insulation
- Roofs whose membrane or build-up is not suitable
- Leaks from plumbing or windows

Roofs we survey in Hanworth
- Flat roof membranes
- Green roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
- Single-ply roofs
- Commercial flat roofs
The survey, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes a length of time set by the size of the roof and how it’s built, which we set out in the quote. Some parts of a survey depend on the weather, so a visit to Hanworth is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- Gather any invoices or paperwork from past roof work
- Keep pets out of the way during the survey
- If it is not your property yet, arrange access through the agent
Booking a survey
If you have photos of the roof, send them over. Pictures from ground level or a window are fine; never climb up to get a better view. To send them or to book, call 07833 053749 or email us.

Practical tips
Over many surveys, some simple habits stand out:
- Use boards when working on the roof
- Limit access to the roof
- Do not keep patching the same spot
- Keep outlets clear of debris
If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer, and moisture readings can help.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
Can I check my roof myself?
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
The one thing to avoid is getting up close. Roofs are fragile and slippery. That is where a survey comes in.
Landlord and commercial surveys in Hanworth
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time, and they’re priced for the size.
