Electronic leak detection for homes and businesses in New Charlton
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. If testing isn’t possible, we will say so. Typical surveys look at punctures from foot traffic or tools and gaps at membrane joints, across single-ply roofs, flat roof membranes and green roofs.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in New Charlton shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, each with a short note and a photograph. It records what’s sound as well as what isn’t.

Tips from our surveys
Most of what helps is simple and safe from ground level. A few suggestions:
- Tell us about the membrane and build-up if you know it
- Test new membranes before covering them
- Get leaks traced quickly
- Check trades protect the waterproofing
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Ask trades working on the roof to protect the membrane when fitting equipment. Have the roof looked at after other work.
Local flat roofs in New Charlton
With Queen's House about 1.8 miles west, New Charlton sits in an area with a long building history. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof. Within a mile and a half or so of New Charlton there are several hotels, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
If you live in an older home near St Catherine Labouré, the flat roofs on later extensions tend to wear out long before the main roof. Shop and office owners around Gallions Reach Shopping Park may find that the flat roofs over shops and commercial units are worth checking before a leak, not after.

Your questions about electronic leak detection in New Charlton
How do I find out if my home in New Charlton is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Do you look at commercial flat roofs near New Charlton, such as hotels?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
How quickly is the report sent?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email, ready to forward.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, so wherever there is a hole, it passes through. That is how we locate breaches you can’t see.
What will the report tell me?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
How many surveys have you done?
More than 5,000 surveys over 20+ years, across London and South East England.
Does ELD include fixing the breach?
No. We test the membrane and report. The report shows where each breach is so your roofer can fix them.
What we do, step by step
On the day, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can safely be seen, using the ground, windows, the loft and a drone where applicable. The survey typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it’s useful to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Before the survey
- Make sure pets are kept safely away
- Buyers: confirm access with the estate agent or seller
- Gather any invoices or paperwork from past roof work

DIY checks: what’s safe
Look up at the roof after a storm, from the ground: 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.
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
