Electronic leak detection in Hexton
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. You get a written report with photos of each breach found. If you’re worried about failed seams and laps and repairs that haven’t stopped the leak, we can find out what’s behind it, on commercial flat roofs, liquid-applied waterproofing and green roofs alike.
Flat roofs on exposed homes in small places like Hexton take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, frequently around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photo where possible, with the urgent items made clear.

Flat roofs in Hexton
Harlington Manor, about 4.3 miles west, is one of the historic houses in the wider area around Hexton. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Landlords with a home close to Harlington station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you look after a building such as Hexton Junior Mixed and Infant School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
Hexton is in Hertfordshire. Hexton is part of the area we cover and the surrounding area across London and South East England. Hexton is one of the places in Hertfordshire where we work for electronic leak detection. We also survey roofs in Milton Keynes.

Practical tips
A survey works best with a little help from you, before and after. Tips:
- Note where leaks show inside and when
- Keep foot traffic on flat roofs to a minimum
- Find the breach before more patching
- Have roof specifications to hand
Where the evidence points to walls, copings or rooflights, we’ll note it, so other causes can be checked.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
What happens if roof problems are left?
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole first so your roofer knows where to work. Where a roof is exposed, as many are in small places like Hexton, driving rain gets into any weakness, and damp in older walls is slow to dry out.

How it works
On the day, we begin with a quick chat about the roof and anything that is worrying you. After that, we look at everything we can see safely, from ground level, from windows, in the roof space and by drone where it applies. The survey normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. Rural addresses near Hexton can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Preparing for the visit
- Leave a clear route to the loft
- Gather any invoices or paperwork from past roof work
- Agree roof access with the managing agent if it is shared
Getting a price
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. Otherwise, simply ring 07833 053749 or email us whenever suits you.

What we are asked to look at in Hexton
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
We are frequently asked to look at:
- Leaks through a flat roof with no obvious cause
- Stains far from any visible defect
- Leaking laps in the waterproofing
- Leaks at pipes, outlets or fixings
For an older house near a landmark such as Church of St Faith (Church of England), flat-roofed rear additions and dormers added over the years are worth checking.
Choosing a roof surveyor
- Their report turnaround times
- Whether VAT is in the quoted price
- What experience they bring
- Whether they hold professional indemnity and public liability insurance
Common questions in Hexton
Do you cover Hexton?
We do. Every survey there gets the same written report with photos.
Will you come out to Hexton?
Yes. Hexton 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 the repair part of the test?
No. We test the membrane and report. You get the breach locations with photos so your roofer can fix them.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you’ll need a RICS survey as well.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys.
What do I do with the report?
We email you the written report with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
How the survey changes by roof type
Single-ply membranes
ELD often works on single-ply membranes, depending on the type and build-up.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Whether ELD works depends on the coating and build-up.
