Electronic leak detection in Letchmore Heath: what you get
ELD can be carried out in more than one way. Low-voltage methods typically need a wet roof surface, 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 will explain our choice. If neither method suits your roof, we will tell you at the outset. Typical surveys look at damp inside with no sign on the roof and breaches hidden under paving or planting, on flat roof membranes, green roofs and single-ply roofs.
Some older homes in villages like Letchmore Heath are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that is said too.

What happens if roof problems are left?
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. For older village homes like those around Letchmore Heath, the right replacement materials aren’t always easy to find quickly. Spotting a problem early leaves room to find them.

When to book a survey in Letchmore Heath
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
We’re frequently asked to look at:
- Gaps at membrane joints
- Leaks through a covered membrane
- Leaks at pipes, outlets or fixings
- New membranes needing a check before handover
If you own a rental within reach of Radlett station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
What to check before booking
- How much experience they have with roofs like yours
- How they plan to inspect the roof safely
- Whether VAT is added on top
- When you will get the report
Your questions about electronic leak detection in Letchmore Heath
Will you come out to Letchmore Heath?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is Letchmore Heath in the area you cover?
We do. The survey and report are the same in Letchmore Heath as anywhere else, and visits run on weekdays and weekends.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Do you use drones?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules. We’re a CAA-registered drone operator.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days as you book.
Do I have to be there for the survey?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you when booking.
How much time does ELD need?
It depends on the size of the roof and its build-up. We will give you an idea when we quote.
How it works
The visit typically starts outside and finishes in the loft: outside views come first, then the roof space if there’s safe access. All told, expect a time that depends on the roof’s area and construction, which we set out in the quote. In a hamlet or village like Letchmore Heath, a postcode does not always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- First, you tell us about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
How to prepare
- Tell us about parking before the day
- Move anything stored under the loft hatch
- Note where any stains or damp appear
Arrange a survey
If you are buying, it is useful to book soon after your offer is accepted, so there is time to use the report before exchange. Otherwise, simply phone 07833 053749 or email us whenever suits you.

What electronic leak detection looks like in Letchmore Heath
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. High Elms Manor, about 3.5 miles north-west, is one of the historic houses in the wider area around Letchmore Heath. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
For site and facilities teams at buildings like Fair Field Junior School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you run a business near Harlequin Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.

What we look for on each type of roof
Inverted and paved roofs
We will tell you if your inverted or paved roof isn’t suitable.
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We look at this first.
What we cannot see
Every survey has limits, and we’d rather be clear about that before you book. Keep these in mind:
- Some conductive membranes
- Fixing the holes we find
- Parts of the roof covered by fixed equipment
If in doubt, phone 07833 053749 or use the contact form and we’ll suggest the right survey. What a survey covers and does not.
What we look at
- Flat roof membranes
- Roof terraces and balconies
- Single-ply roofs
- Green roofs
- Commercial flat roofs
- Liquid-applied waterproofing
Tips that help
Over many surveys, some simple habits stand out as worth the effort:
- Use boards when working on the roof
- Record dates and spots where water appears
- Find the breach before more patching
- Don’t let outlets block
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that and other checks can help judge it.
Consider testing a new membrane before it is covered. It’s easier to find holes before more layers are added.
