Electronic leak detection for homes and businesses in St George's Fields
Water can travel under a flat roof membrane before it shows inside. That makes leaks hard to trace by eye. ELD tests the waterproofing directly, to find where it has been breached. We test and report, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. We are often asked to look into waterproofing to test before it’s covered and holes around roof penetrations, on single-ply roofs, commercial flat roofs and liquid-applied waterproofing.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in St George's Fields, the roof above may belong to the building rather than one flat.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photo where possible, and recommendations are put in order of urgency where relevant.

Different roofs, different checks
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check before we quote.
Honest limits
Every survey has limits, and we’d rather be clear about that before booking. Bear these in mind:
- Leaks from plumbing or windows
- Sections we can’t safely access

How it works
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. In a London area like St George's Fields, the main things to sort out are parking and access: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from ground level, windows, the loft and, where it’s safe, the roof itself.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before we arrive
- Agree roof access with the managing agent if it is shared
- If it isn’t your property yet, arrange access through the agent
- Dig out any old roof reports or invoices
How to book
Photos help, if you have them. Pictures from the ground or a window are fine. To send them or to book, ring 07833 053749 or use the contact form.

DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
It is useful to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
Your questions about electronic leak detection in St George's Fields
Does a conservation area affect roof work in St George's Fields?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Will parking be an issue for a roof survey in St George's Fields?
Typically it is manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.

You receive the written report by email, with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.

What electronic leak detection looks like in St George's Fields
Benjamin Franklin House, about 1.1 miles north-west, is one of the historic houses in the wider area around St George's Fields. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, 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 St George's Fields. If you look after one, a leak through a flat roof can put a room out of use.
Anyone responsible for a site like St George's Cathedral Catholic Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you look after a shop, office or commercial unit, for example near Gabriel's Wharf, the flat roofs over shops and commercial units are worth checking before a leak, not after.
