Electronic Leak Detection in Tokyngton
Find out what’s going on with the flat roof membrane before you decide what to do next. Electronic leak detection in Tokyngton.
- Damp inside with no sign on the roof
- Repairs that haven’t stopped the leak
- Leaks through a flat roof with no obvious cause
How electronic leak detection works in Tokyngton
ELD can be carried out in more than one way. Low-voltage testing is usually done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof and we explain which we’ll use. We will say if your roof doesn’t suit either method before any testing starts. If you’re worried about breaches around outlets and penetrations and leaks through a flat roof with no obvious cause, we can find out what’s behind it, on liquid-applied waterproofing, roof terraces and balconies and flat roof membranes alike.
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 block or conversion in Tokyngton, the flat roof is often a shared part of the building.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

Useful tips for Tokyngton property owners
A survey works best with a little help from you, before and after. Tips:
- Keep foot traffic on flat roofs to a minimum
- Share any drawings of the roof
- Note where leaks show inside and when
- Keep outlets clear of debris
If we think the leak isn’t coming through the membrane, the report says so, with a suggestion of what to check next.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
How the survey changes by roof type
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Green and ballasted roofs
ELD is easier on a new roof before it’s covered.
How we price electronic leak detection
Prices always include VAT. The things that change the price are:
- Features like valleys, chimneys, dormers and parapets
- Roof area
- Height and safe access
- The use of thermal imaging or a drone
To find out what your survey will cost, call 07833 053749 or drop us an email and let us know about the roof. The price is agreed before a date is set.
What we need to know
You don’t need to know any roofing terms. It’s enough to let us know:
- What kind of property and roof it is
- The property’s address and postcode
- When you need the report by
- Access details, like a loft hatch or a shared roof
Photos help, if you have them. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, ring 07833 053749 or drop us an email.
How it works
Once we have finished looking, we write up our findings as a written report with photos, sent to you by email. As for time on site, most surveys take a length of time set by the size of the roof and how it’s built, and we’ll give you a guide when quoting. In a London conversion, the way into the roof space is often from a communal landing or the top flat. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Tokyngton runs like any other.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- 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.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- If you’re buying, check with the agent that we can get in
- Make a note of anything you’d like us to look at
- Check pets are kept safely away
Book a survey

Advice
Flat roofs in Tokyngton
The wider area around Tokyngton has a long history of building, with Pitzhanger Manor about 2.8 miles south-west. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. There are several hotels within about a mile and a half of Tokyngton, 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.
If your home is one of the older ones in the streets near St Michael the Archangel, flat-roofed rear additions and dormers added over the years are worth checking. If you look after a shop, office or commercial unit, for example near London Designer Outlet, a flat roof over a business is out of sight and out of mind until it leaks. For hotels and guest houses around Tokyngton, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do.

Your questions about electronic leak detection in Tokyngton
Does a conservation area affect roof work in Tokyngton?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Can parking be tricky for a visit in Tokyngton?
It depends on the street. If Tokyngton has controlled parking where you are, a visitor permit is the easiest answer.
Does someone need to be in?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Does ELD work under paving or planting?
On some roofs, yes. What sits on the membrane affects the method so we look at the roof first.
How soon will I get the report?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.

What you can safely check yourself
