Electronic leak detection in Rush Green, Hertfordshire
Not sure what state the flat roof membrane is in? We carry out electronic leak detection in Rush Green and across Hertfordshire, with plain-English findings.
- Leaks showing away from the breach
- Breaches around outlets and penetrations
- Punctures from foot traffic or tools
Do you need electronic leak detection in Rush Green?
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
Here are some of the things we see often:
- Leaks that return after repairs
- Leaking laps in the waterproofing
- Damage from equipment installers
- Leaks under green or ballasted roofs
Take a building like Wheatcroft Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Choosing a roof surveyor
- When you’ll get the report
- Whether the inside of the roof is included
- What happens after the report arrives
- How much experience they have with roofs like yours
Electronic leak detection in Rush Green: what you get
There are different ELD methods. Low-voltage testing is normally done with the surface wet, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. If neither method suits your roof, we’ll tell you at the outset. If you are worried about failed seams and laps and new roofs to check before paving or planting, we can find out what’s behind it, whatever the roof.
Flat roofs on exposed homes in small places like Rush Green take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are typically the first part of a flat roof to go.
The report is written in plain words, so you don’t need to be a roofer to follow it. Each point is backed by a photograph where possible.

Before and after the survey
Nothing here needs a ladder. A few suggestions:
- Keep a note of leaks after rain
- Check trades protect the waterproofing
- Get leaks traced quickly
- Find the breach before more patching
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Make sure contractors protect the waterproofing when fitting equipment. Have the roof looked at after other work.

What electronic leak detection looks like in Rush Green
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. England has around 10,000 conservation areas and about 500,000 listed buildings. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so check with the council.
For an older house near a landmark such as Church of the Holy Trinity, the joins between later flat roofs and the old walls are where problems normally start. If you let a flat or house near Ware station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Your questions about electronic leak detection in Rush Green
Is Rush Green within the area you cover?
Yes. Rush Green is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and South East England. Just mention lanes, gates or anything else about the route when booking.
Is my home in Rush Green listed or in a conservation area?
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 test for asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Which method do you use?
It depends on the membrane and the build-up. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
How much time does ELD need?
The roof’s size and build-up decide how long it takes. You will know roughly how long before we start.
What does the report include?
It explains what we saw, what it means and what we’d suggest, backed by photographs. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Can you test a green or ballasted roof?
Sometimes. It depends on the build-up and the layers above the membrane, and some may need lifting. We will discuss it before we quote.
Why it is worth a survey now in Rush Green
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole first, so the repair can be targeted. Older and listed buildings around Rush Green may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.

How it works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. The inspection then takes a time that depends on the roof’s area and construction, which we’ll explain when we quote. In a hamlet or village like Rush Green, a postcode does not always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Getting ready for the survey
- Have keys ready for side gates, garages or roof access doors
- Move anything stored under the loft hatch
- Keep pets out of the way during the survey
Booking a survey
Getting a price is simple: just call 07833 053749 or send us an email and give us some details about the property and we’ll explain which survey suits. The price is agreed up front.
