Electronic leak detection in Palmers Green
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It can be used to trace an existing leak or check a new membrane before handover. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Let us know about your roof to find out more. We survey roof terraces and balconies, single-ply roofs and flat roof membranes, and the problems we’re asked to look at most are leaks that return after repairs and leaking laps in the waterproofing.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Palmers Green, access is agreed with whoever manages the roof before the visit. Plant bases, rooflights and cable entries are all places where water can get in.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Questions from Palmers Green
Do you cover Palmers Green?
Yes. We work right across London and the South East, and Palmers Green is part of that. You can phone 07833 053749 or send us an email with the address and some details.
Will parking be an issue for a roof survey in Palmers Green?
It rarely stops a survey, but it’s worth planning. Let us know the parking rules on your street and we will work around them.
Can you tell me if my roof has asbestos?
No. We don’t sample or test for asbestos. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
How is ELD priced?
Each roof is quoted on its size and build-up. Send us details of the roof, and ring 07833 053749 or drop us an email for a quote.
Do you look in the roof space?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys, across London and South East England.
How much time does ELD need?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.

EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We’ll say if the test will not work.
Single-ply membranes
ELD frequently works on single-ply membranes but it depends on the product and layers.
Common roof problems in Palmers Green
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
Look out for signs like these:
- Holes around roof penetrations
- New roofs to check before paving or planting
- Leaks through a covered membrane
- Stains far from any visible defect
If you own a rental within reach of Palmers Green station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Electronic leak detection in Palmers Green: local notes
Bruce Castle, about 1.9 miles south-east, is one of the historic houses in the wider area around Palmers Green. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. 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. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Parking in Palmers Green, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier. Shop and office owners around The Mall Wood Green may find that the flat roofs over shops and commercial units are worth checking before a leak, not after.

What we do, step by step
Every visit follows the same pattern: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photos as we go and record our findings for the written report. It usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. From the street, a London terrace normally shows only its front slope or parapet, so a visit in Palmers Green moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- 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.
Preparing for the visit
- Mention any parking restrictions on your street
- For a flat or shared roof, check access with the building owner or managing agent
- Move anything stored under the loft hatch

Tips that help
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Share any drawings of the roof
- Limit access to the roof
- Act on new leaks promptly
- Do not keep patching the same spot
Questions about the results are welcome. We will explain what was found and what it means.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
