Electronic leak detection for homes and businesses in Hailey
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly and locates the breach. We test and report and leave the repair to your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. If you are worried about leaks through a flat roof with no obvious cause and damage from equipment installers, a survey will tell you what’s going on, whatever the roof.
In a village or hamlet like Hailey, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them as you book.
The report is written in plain words, so it makes sense without any roofing background. Photos show what each point refers to, with the urgent items made clear.

Hailey: your questions answered
Does a conservation area affect roof work in Hailey?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Will you come out to Hailey?
Yes, Hailey is on our map. A small place gets exactly the same survey as a big one.
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 will talk to you about another date.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Tell us what you know about the roof and we’ll check whether ELD will work.
What do I do with the report?
You receive the written report by email, with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Do you look in the roof space?
If the survey needs it and the loft space can be reached safely, yes. Please clear anything stored under the hatch.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Send us details of the roof. Just phone 07833 053749 or send us an email for a quote.
Before and after the survey
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Keep a note of leaks after rain
- Have roof specifications to hand
- Keep outlets clear of debris
- Do not leave water getting in
If water has been getting in, insulation under the membrane may be wet. That’s something to discuss with your roofer, and moisture readings can help.
Do not leave a flat roof leak running. Water under a membrane can spread.
Common roof problems in Hailey
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
Typical things we’re asked to look at include:
- Breaches hidden under paving or planting
- Leaking laps in the waterproofing
- Leaks showing away from the breach
- Patched roofs that still leak
Landlords with a home close to St Margarets (Herts) station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Choosing a roof surveyor
- What happens after the report arrives
- How long they’ve been surveying roofs
- Whether they hold professional indemnity and public liability insurance
- What the survey won’t cover
Can I check my roof myself?
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
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. Leave anything above ground level to a survey.

What else we do in Hailey
What happens if roof problems are left?
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. Around Hailey, older homes frequently have old roof timbers, and water through a failed covering can rot timber if it’s left.

What electronic leak detection looks like in Hailey
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. An older home may be listed, or stand in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. In either case, a change of roofing material may need consent.
If you live in an older home near Church of the Holy Trinity, the joins between later flat roofs and the old walls are where problems typically start. For site and facilities teams at buildings such as Roselands Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

How it works
The visit has one job: to see as much of the flat roof membrane as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. It usually takes as long as needed for the membrane area and the build-up, which we’ll explain when we quote. Older rural homes like those around Hailey can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- 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.
How to prepare
- Tell us where we can park nearby
- Have any paperwork from past roof work to hand
- Note where any stains or damp appear
Arrange a survey
A quick phone call is typically the easiest start: call 07833 053749 or email us and we’ll ask a few questions about the roof. The price is agreed before a date is set.
