Electronic leak detection in Jersey Farm, Hertfordshire
A careful look at the flat roof membrane at your property in Jersey Farm, and put it all in a photo-illustrated written report.
- New membranes needing a check before handover
- Leaking laps in the waterproofing
- Patched roofs that still leak
Common roof problems in Jersey Farm
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs, depending on the build-up.
We’re often asked to look at:
- Leaking laps in the waterproofing
- Leaks that return after repairs
- New membranes needing a check before handover
- Water coming in under a flat roof
If you look after a building like Skyswood Primary & Nursery School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
Choosing a roof surveyor
- What the report includes, and whether it has photos
- What follow-up you get after the report
- Their drone registration, if they fly one
- How soon the report will arrive
How electronic leak detection works in Jersey Farm
ELD can be carried out in more than one way. Low-voltage testing is usually done with the surface wet, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof and we explain which we’ll use. If neither method suits your roof, we’ll tell you before any testing starts. Typical surveys look at waterproofing to test before it’s covered and leaks through a covered membrane, on roof terraces and balconies, single-ply roofs and flat roof membranes.
Around a smaller place like Jersey Farm, flat roofs normally cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it is covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Surveys for landlords and agents in Jersey Farm
Letting agents often book on a landlord’s behalf, with the report sent to whoever needs it. Access is agreed with the tenant beforehand.
Where a roof is shared: we need access agreed with the building owner or managing agent. Let us know about it when you book and we will plan the visit with that in mind.
What affects the cost of electronic leak detection
The price reflects the time and kit the roof needs. The main factors are:
- The roof’s overall size
- The type of building, from a house to a block or an office
- How complicated the roof is, with its valleys, chimneys and parapets
- Extensions, dormers and garages with roofs of their own
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.

What electronic leak detection looks like in Jersey Farm
About 2.3 miles west lies Childwickbury Manor, a reminder of how long the area around Jersey Farm has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Take an older house close to Saint Mary's: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. If you own a rental within reach of St Albans station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Useful tips for Jersey Farm property owners
Nothing here needs a ladder. A few suggestions:
- Limit access to the roof
- Check new waterproofing before handover
- Let us know about the membrane and build-up if you know it

Your questions about electronic leak detection in Jersey Farm
Do you cover smaller places like Jersey Farm?
Yes, Jersey Farm is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is Jersey Farm in the area you cover?
We do. The survey and report are the same in Jersey Farm as anywhere else, and visits run on weekdays and weekends.
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.
What does electronic leak detection do?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage methods are normally carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach.
How it works
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. With a bit of garden around a house, as there often is around Jersey Farm, the roof can be viewed from several angles. Mention any side of the property we can’t get to. The loft, where there’s safe access, completes the picture.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- 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.
Preparing for the visit
- Let us know about parking before the day
- Leave side gates unlocked
- Show us where any leaks or stains appear
