Electronic leak detection for homes and businesses in Herongate
We carry out electronic leak detection on flat roofs in Herongate and across London and the South East. Testing typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Electronic leak detection is quoted for your roof, because the method depends on the roof. You get a written report with photos. Common reasons to book are waterproofing to test before it’s covered and water coming in under a flat roof, on green roofs, roof terraces and balconies and liquid-applied waterproofing.
In a small place like Herongate, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, normally show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.
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.

Do you need electronic leak detection in Herongate?
When the membrane is buried, holes cannot be seen at all. Electronic methods can help on some of these roofs, depending on the build-up.
These are some of the problems a survey can pick up:
- Repairs that haven’t stopped the leak
- Damage from equipment installers
- Damp inside with no sign on the roof
- Leaks through a covered membrane
If you look after a building such as Brentwood County High School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.
Questions to ask before booking
- Are they insured for the work?
- What’s outside the scope of the survey
- What experience they bring
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
Different roofs, different checks
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Bituminous membranes
Many flat roofs use bitumen-based membranes. The build-up decides which method will work.
What we do, step by step
Every roof is different, but as a rough guide the survey takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. If you have questions on the day, just ask. For a village or hamlet like Herongate, the journey is planned in advance: let us know about lanes, gates and parking. On the day, we inspect everything that’s safely in view, inside and out.
- 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.
- 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.
Before we arrive
- Let us know about parking near the property
- Check pets are kept safely away
- Find any records of previous roof work

Questions from Herongate
Is my home in Herongate listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you cover smaller places like Herongate?
Yes. Herongate is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when you book.
Is my roof suitable for ELD?
That depends on the roof’s membrane and layers. Share any details you have and we will confirm suitability.
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, while outside access can be discussed as you book.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day. Just say which days work for you.
How do I book a survey in Herongate?
To book, phone 07833 053749 or send us an email and let us know the address and what you need to know. We’ll confirm the price and agree a day with you.
Do you use low-voltage or high-voltage testing?
The roof decides the method. We’ll explain why when we quote.
What this survey cannot tell you
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Moisture spread under the membrane
- Build-ups without a suitable layer below
- Repairing the breaches (that’s for your roofer)
Not sure which survey suits your roof? You can phone 07833 053749 or email us and we’ll tell you before you book. The full list of what we check.
What this survey covers
- Single-ply roofs
- Liquid-applied waterproofing
- Flat roof membranes
- Commercial flat roofs
- Roof terraces and balconies
- Green roofs
Leave it or get it looked at?
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. For older village homes like those around Herongate, the right replacement materials are not always easy to find quickly. Spotting a problem early leaves room to find them.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You’ll know the price for your roof before you book.
