How electronic leak detection works in Trash Green
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It can be used to trace an existing leak or to test a new membrane before it is covered. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Tell us about your roof to find out more. We are frequently asked to look into breaches hidden under paving or planting and gaps at membrane joints, across liquid-applied waterproofing, roof terraces and balconies and green roofs.
Some older homes in villages like Trash Green 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. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
Where we cannot see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t.

Electronic leak detection in Trash Green: local notes
Mapledurham House, about 4.7 miles north, is one of the historic houses in the wider area around Trash Green. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If your home is one of the older ones in the streets near Church of St Mary the Virgin, the flat roofs on later extensions tend to wear out long before the main roof. If you let a flat or house near Theale station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Why it is worth a survey now in Trash Green
Testing a new membrane before it’s covered is easier than tracing a leak later. Covered roofs are harder to test. Matching old materials, such as handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Useful tips for Trash Green property owners
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Share any drawings of the roof
- Keep a note of leaks after rain
- Check new waterproofing before handover
- Do not leave water getting in
If anything in the report is not clear, ask us. We can talk you through the findings.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
Questions from Trash Green
Is Trash Green in the area you cover?
Yes, Trash Green is one of the places we work. Every survey there gets the same written report with photos.
Does a conservation area affect roof work in Trash Green?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you climb onto every roof?
Only where it is safe to do so. We inspect what can safely be seen: from the ground, from windows, from inside the loft space, from the roof where it is safe and by drone where applicable. The report says if anything couldn’t be seen.
What does the report include?
You get our findings in writing, part by part, with photos, finishing with recommendations. Points are put with the most urgent first where relevant.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access.
Can you test a green or ballasted roof?
Sometimes. The layers on top and the build-up below decide it and parts may need to be lifted. We will discuss it before we quote.
Does electronic leak detection work on all membranes?
ELD does not suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. We’ll tell you if yours is not suitable before testing.
Rented homes, blocks and businesses
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client.
How the survey changes by roof type
EPDM rubber roofs
Certain rubber membranes are conductive which can limit electronic testing. We’ll say if the test will not work.
Liquid-applied waterproofing
Liquid waterproofing has no laps but holes and thin areas can occur. Suitability for ELD depends on the system.
How it works
On the day, we start by asking what you’ve noticed and what you want to find out. After that, we look at everything we can see safely, from the ground, from windows, in the loft space and by drone where applicable. The survey typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Rural addresses near Trash Green 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 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 testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Preparing for the visit
- Jot down any questions you want answered
- Make sure the loft hatch can be reached
- Unlock side gates and any roof access doors
Arrange a survey
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, ring 07833 053749 or send us an email with the address and the days you’d prefer.
Advice
When to book a survey in Trash Green
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
A survey makes sense if you’ve noticed:
- Breaches around outlets and penetrations
- Failed seams and laps
- Patched roofs that still leak
- Stains far from any visible defect
Anyone responsible for a site like Burghfield St Mary's C.E. Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Questions to ask before you book
- Whether the inside of the roof is included
- Whether you can ask questions once you have the report
- What exactly goes into their report
- Whether VAT is in the quoted price
