How electronic leak detection works in Hertingfordbury
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work and parts may need to be lifted. We talk this through before we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. We will tell you if the roof can’t be tested. We’re often asked to look into breaches hidden under paving or planting and new membranes needing a check before handover, on green roofs, flat roof membranes and commercial flat roofs.
Flat roofs on exposed homes in small places like Hertingfordbury take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, usually show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
Every survey ends with a written report, with photographs, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Electronic leak detection in Hertingfordbury: local notes
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Hertingfordbury has a number of hotels within about a mile and a half, and like offices and blocks, hotels frequently sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
If you live in an older home near Church of St Mary and St John, flat-roofed rear additions and dormers added over the years are worth checking. For landlords with property near Hertford North station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

The survey, step by step
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes more time on a big roof than a small one, with the construction of the roof playing a part too. Somewhere like Hertingfordbury needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect what can be seen safely, inside and out.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
How to prepare
- Have any questions written down, so nothing gets missed
- Leave side gates unlocked
- Buyers: confirm access with the estate agent or seller
Arrange a survey
A quick phone call is normally the easiest start: call 07833 053749 or send us an email. You will have a price before anything is arranged.

Practical tips
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Limit access to the roof
- Consider ELD before paving or planting goes on
- Tell us about the membrane and build-up if you know it
- Do not keep patching the same spot
Wet insulation may need attention after a leak. Your roofer can advise on that and other checks can help judge it.
Ask trades working on the roof to protect the membrane when they work up there. Check the roof after they’ve finished.
Do you need electronic leak detection in Hertingfordbury?
Repeated leaks after repairs suggest the real breach hasn’t been found. Electronic testing helps pinpoint it.
Most people get in touch after spotting something like this:
- Patched roofs that still leak
- Leaks under green or ballasted roofs
- Breaches around outlets and penetrations
- Damp inside with no sign on the roof
Digswell House lies about 4.6 miles north-west, so building around Hertingfordbury goes back a long way. Older houses nearby frequently have flat roofs added much later, built to very different standards from the main roof.
Before booking any roof surveyor
- What the report includes, and whether it has photographs
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- What they won’t be able to tell you
- Are they insured for the work?
Leave it or get it looked at?
Testing a new membrane before it’s covered is easier than tracing a leak later. Covered roofs are harder to test. Older cottages and farmhouses around Hertingfordbury can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Hertingfordbury questions
Will you come out to Hertingfordbury?
Yes, we do. We work right across London and the South East, and smaller places are part of that. Longer journeys are simply planned ahead of time.
Do you cover commercial flat roofs around Hertingfordbury?
Yes. As well as homes, we check flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you’ll get a quote based on the building.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
How long does electronic leak detection take?
Testing normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too.
Can you survey at the weekend?
Surveys run on weekdays, Saturdays and Sundays. To arrange a date, phone 07833 053749 or use the contact form.
Will you check the loft?
Normally, if there’s one and it can be reached safely. The loft space can show things the outside can’t, such as damp timbers, staining or daylight.
What does the report include?
You get our findings in writing, part by part, with photos, finishing with recommendations. Points are put in order of urgency where relevant.
