Hanscombe End Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes around Hanscombe End, with a written report you can act on. Weekday and weekend visits available.
- New membranes needing a check before handover
- Damp inside with no sign on the roof
- Leaks through a flat roof with no obvious cause
What we look for on each type of roof
Bituminous membranes
Bituminous roofs often have laps and old repairs where breaches occur. Testing depends on the roof.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check before we quote.
How electronic leak detection works in Hanscombe End
You get a report showing the location of each breach with photos. It tells your roofer exactly where to repair instead of hunting for the leak. We don’t estimate repair costs, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. You get a photo-illustrated written report. We survey liquid-applied waterproofing, green roofs and flat roof membranes, and common reasons people get in touch are damp inside with no sign on the roof and holes around roof penetrations.
In a small place like Hanscombe End, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
We write the report in plain English, so you do not need to be a roofer to follow it. Each point is backed by a photo where possible, and recommendations are put with the most urgent first where relevant.

Businesses and commercial landlords can book us too. Bigger roofs take more time.
Tips that help
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Stay off the flat roof unless needed
- Ask contractors to protect the membrane
- Find the breach before more patching
- Don’t let outlets block
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Make sure contractors protect the waterproofing when fitting equipment. Have the roof looked at after other work.
Signs you need electronic leak detection in Hanscombe End
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
Look out for signs like these:
- Breaches around outlets and penetrations
- Leaks through a flat roof with no obvious cause
- Damp inside with no sign on the roof
- Leaks that return after repairs
Anyone responsible for a site like Shillington Lower School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
Questions to ask before booking
- Their drone registration, if they fly one
- Whether the loft space is looked at, where there is one
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Whether they hold professional indemnity and public liability insurance
Hanscombe End questions
Do you cover smaller places like Hanscombe End?
Yes, smaller places are covered as well as towns. We survey roofs across London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Do you carry out roof surveys in Hanscombe End?
We do. The survey and report are the same in Hanscombe End as anywhere else, and visits run on weekdays and weekends.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions are not right, we’ll talk to you about another date.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys.
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 every flight depends on the airspace and the weather.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning. Mention it when you get in touch and we’ll plan the survey around it.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage testing normally needs a wet surface and high-voltage methods need the membrane dry and exposed.
DIY checks: what’s safe
What you cannot do safely is get up close. Roofs are fragile and slippery. That part is for a survey.
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
Flat roofs in Hanscombe End
Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you live in an older home near Church of All Saints, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

How it works
We do not take risks to get a closer look. Everything that can safely be seen is inspected, and if part of the roof cannot be seen, the report says so. Most visits take a length of time set by the membrane area and the build-up, which we’ll explain when we quote. Around Hanscombe End, older homes can have small or awkward roof spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it’s safe.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- Have any paperwork from past roof work to hand
- Note where any stains or damp appear
- Make a note of anything you’d like us to look at
