Electronic leak detection in Selham
ELD can be carried out in more than one way. Low-voltage methods usually need a wet roof surface and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof, and we will explain our choice. We’ll say if your roof does not suit either method before any testing starts. If you’ve noticed waterproofing to test before it’s covered and punctures from foot traffic or tools, a survey will tell you what’s going on.
In a small place like Selham, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which frequently last around 15–20 years, normally show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are typically the first part of a flat roof to go.
It is not only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

How the survey changes by roof type
Bituminous membranes
ELD is often possible on bituminous membranes, depending on what’s below.
EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We’ll tell you if yours is not suitable.
Common roof problems in Selham
Other trades on the roof can puncture the waterproofing. Fixings, equipment and foot traffic can leave small holes.
Things that often lead to a survey include:
- Breaches around outlets and penetrations
- Punctures from foot traffic or tools
- Water coming in under a flat roof
- Leaks under green or ballasted roofs
If your home is one of the older ones in the streets near Church of St James, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Before booking anyone
- Which parts of the roof they’ll actually see
- Whether any drone flown is registered with the CAA
- Whether the loft is part of the inspection
- Their report turnaround times
What happens on the day
After the inspection, everything we found is written up as a photo-illustrated written report, sent to you by email. As for time on site, it normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Somewhere like Selham needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect what can safely be seen, inside and out.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Getting ready for the survey
- Show us where any leaks or stains appear
- Keep pets in another room
- Have keys ready for side gates, garages or roof access doors
Getting a price
Booking is simple: just ring 07833 053749 or send us an email and give us a few details about the property and we will explain which survey suits. We confirm the price before anything is booked.

Do you cover smaller places like Selham?

No. ELD is testing only. You get the breach locations with photos for your roofer to repair.
How do I arrange electronic leak detection in Selham?
To book, ring 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
How much time does ELD need?
Testing normally takes a length of time set by the size of the roof and how it’s built, and we’ll give you a guide when quoting.
Is my roof suitable for ELD?
ELD does not suit every roof. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof will not work, we will say so before testing.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.

Why it is worth a survey now in Selham
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. Matching old materials, such as handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Before and after the survey
A few practical points come up again and again on our surveys. They apply to most roofs:
- Use boards when working on the roof
- Check new waterproofing before handover
- Keep outlets clear of debris
- Do not keep patching the same spot
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Make sure contractors protect the waterproofing when fitting equipment. Have the roof looked at after other work.
