Electronic Leak Detection in Boarshead
An experienced roof surveyor for electronic leak detection in Boarshead. Over 5,000 surveys and 20+ years behind us.

- Patched roofs that still leak
- Leaks at pipes, outlets or fixings
Different roofs, different checks
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane and that changes how testing works.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.
About our electronic leak detection in Boarshead
There are different ELD methods. Low-voltage testing is typically done with the surface wet, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof and we explain which we’ll use. If neither method suits your roof, we’ll tell you at the outset. We are often asked to look into breaches around outlets and penetrations and leaks through a covered membrane, across single-ply roofs, green roofs and liquid-applied waterproofing.
In a small place like Boarshead, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, typically 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.
Where we can’t see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t.

Boarshead: your questions answered
Is Boarshead within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Just mention lanes, gates or anything else about the route as you book.
Is Boarshead in the area you cover?
Yes. We survey roofs across London and South East England, and Boarshead is part of that. Just call 07833 053749 or use the contact form and let us know about the property, and we will talk through which survey suits.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through, which shows us where the hole is.
How long have you been surveying roofs?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.
Does electronic leak detection work on all membranes?
ELD does not suit every roof. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof won’t work, we will say so before testing.
Will I get photos?
Yes. The report includes photos of what we found.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage methods are usually carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Local flat roofs in Boarshead
With Groombridge Place about 3.3 miles north, Boarshead sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Many older homes in Sussex have handmade clay tiles and tile-hung walls. Horsham stone slab roofs survive on some old Sussex buildings, alongside oast houses and timber-framed Wealden hall houses. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you own a rental within reach of Eridge station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Boarshead is about 2 miles north-east of Crowborough, in East Sussex. In Boarshead, as across East Sussex, every roof gets the same careful survey. Boarshead is one of the places in East Sussex where we work for electronic leak detection. For surveys nearby, see our Crawley page.

What a survey costs
When we price a survey, we consider:
- The use of thermal imaging or a drone
- Height and safe access
- How complicated the roof is, with its valleys, chimneys and parapets
- Extensions, dormers and garages with roofs of their own
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
Helping us price your survey
When you call or email, these details help:
- The style of property, from a terrace to a block
- How the loft is reached, if there is one
- Photos of the roof, taken safely from the ground or a window
- Why you want a survey: buying, a leak, a storm or new work
If you are buying, it is useful to book soon after your offer is accepted, so there is time to use the report before exchange. For any other survey, just call 07833 053749 or email us when you’re ready.
For landlords and managing agents
Surveys can also be booked by buyers’ agents acting for a client. Reports are emailed, so they’re easy to pass on.

What we do, step by step
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take more time on a big roof than a small one, and the build-up of the roof makes a difference too. Cottages and farmhouses around Boarshead often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely, and anything we can’t see is noted.
- 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.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
Preparing for the visit
- For flats, check roof access has been agreed
- Make a note of anything you’d like us to look at
- Point out any leaks or damp patches

Signs you need electronic leak detection in Boarshead
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny, but still let water through.
Signs worth acting on include:
- Breaches around outlets and penetrations
- Holes left by work on the roof
- Damp inside with no sign on the roof
- Water coming in under a flat roof
For site and facilities teams at buildings like Beacon Academy, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.
Choosing a roof surveyor
