Electronic leak detection for homes and businesses in Puddledock
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an 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 written report with photographs of each breach found. We survey liquid-applied waterproofing, green roofs and roof terraces and balconies, and people most often book us about holes around roof penetrations and gaps at membrane joints.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Puddledock, the roof above may belong to the building rather than one flat.
It is not only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

What you can safely check yourself
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Share it with us as you book and it will help the survey.
Electronic leak detection in Puddledock: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. If your home in Puddledock is one of them, bay roofs, hips and later dormers each have their own details. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. Chartwell, about 0.6 miles north-west, is one of the historic houses in the wider area around Puddledock. 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.
If you live in an older home near Holy Trinity Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Controlled parking zones are common in London, so mention any permit rules for Puddledock, along with any off-street space. Landlords with a home close to Edenbridge station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Rented homes, blocks and businesses

Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Let us know about it as you book and we’ll plan the visit with that in mind.

How it works
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. A typical survey takes longer on a large roof than a small one, with the construction of the roof playing a part too. For a visit in Puddledock, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it’s safe.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Preparing for the visit
- Leave side gates unlocked
- Gather any invoices or paperwork from past roof work
- Keep pets in another room

Practical tips
There’s plenty you can do without going near the roof. What helps most:
- Consider ELD before paving or planting goes on
- Note where leaks show inside and when
- Have roof specifications to hand
- Limit access to the roof
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
Ask trades working on the roof to protect the membrane when fitting equipment. Check the roof after they’ve finished.

EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but punctures and seam failures still happen.
Inverted and paved roofs
If the build-up rules out ELD, we will say so.
Your questions about electronic leak detection in Puddledock
Is my home in Puddledock listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is parking a problem for a survey in Puddledock?
It can be, so it helps to let us know about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
What’s in the report?
You get our findings in writing, part by part, with photos. The most urgent items are made clear.
Do you use low-voltage or high-voltage testing?
We choose the method that suits the roof. You’ll know which method we plan to use before we start.
Does the weather affect the survey?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. We’ll rearrange with you if the weather is not right.
Do I have to be there for the survey?
That depends on the survey. Inside the building and in the loft, we need someone to let us in; we will agree the details when booking.
Does electronic leak detection work on all membranes?
Not every roof is suitable. Certain membranes are conductive, and some build-ups lack a suitable layer below. We’ll tell you if yours is not suitable before testing.
What we can’t see
No survey can tell you everything, and it is better to know them up front. Keep these in mind:
- Moisture spread under the membrane
- Areas we can’t reach or that can’t be tested
- Leaks from plumbing or windows
If you are not sure which survey you need, ring 07833 053749 or email us and we’ll give you a straight answer. The full list of what we check.
