Electronic leak detection for homes and businesses in Thundersley
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. We’ll say if ELD will not work on your roof at the start. Any details you have about the membrane and build-up help us decide, like drawings or specifications. It avoids arranging a test that cannot give results. We survey roof terraces and balconies, green roofs and liquid-applied waterproofing, and the problems we’re asked to look at most are leaks under green or ballasted roofs and repairs that haven’t stopped the leak.
Garages and porches on estates in towns like Thundersley often have flat roofs. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check before they’re disturbed. Each kind of covering, from felt to rubber and GRP, is checked in its own way. Asbestos testing isn’t part of what we do, though a report may flag materials that could contain it.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Prices for electronic leak detection in Thundersley
What a survey costs depends on the time and equipment it needs. The main factors are:
- How big the roof is
- The number of roofs, including extensions and garages
- The type of building, from a house to a block or an office
- If the survey needs thermal imaging or a drone
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for the job before booking.
What we need to know
We’ll normally ask about:
- Pictures from the garden or a window, if you have them
- Where any leaks, stains or damp patches show inside
- What’s prompted the survey
- Your postcode, so we can check access and travel
Getting a price is simple: just call 07833 053749 or email us and give us some details about the property and we will recommend the right survey. The price is agreed up front.
How the survey works
We look at the roof from outside and, where it’s relevant and there is safe access, from inside the roof space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey normally takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. In Thundersley, parking is rarely complicated, though it is useful to know about driveways or restrictions. The inspection covers everything that’s safely in view from outside, from windows and from the roof space.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before we arrive
- If you’re buying, let the agent know when we’re coming
- Mention any parking restrictions on your street
- Keep pets out of the way during the survey

Why get it checked now?
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. Extensions and dormers on homes around Thundersley frequently hide the first signs of trouble at their joints with the main roof. Left for a few seasons, it can spoil plaster, skirting and flooring inside.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Why book with us
- Drones and thermal imaging where applicable
- 5,000+ roofs surveyed
- Independent findings on the roof’s condition
- Every finding written up with photos

When to book a survey in Thundersley
When the membrane is buried, holes cannot be seen at all. ELD can work on some covered roofs though it depends on the layers.
A survey can pick up problems such as:
- Holes left by work on the roof
- Leaks through a flat roof with no obvious cause
- Repairs that haven’t stopped the leak
- Leaks at pipes, outlets or fixings
If you look after a building such as Thundersley Primary School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

Local flat roofs in Thundersley
Thundersley is within about 4 miles of the coast, so there is more wind and more salt in the air than further inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Weatherboarded walls and clay tile roofs are typical of older Essex buildings, while many towns grew with post-war and newer estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If your home is one of the older ones in the streets near Church of St Peter, the flat roofs on later extensions tend to wear out long before the main roof. For landlords with property near Rayleigh station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Thundersley is about 3 miles north of Canvey Island, in Essex. Houses, flats, blocks and commercial buildings in Thundersley can all book electronic leak detection, with a written report and photographs every time. Across Essex, we cover Thundersley. For surveys nearby, see our Chelmsford page.

Thundersley: your questions answered
Does being near the coast affect roofs in Thundersley?
Frequently, yes. Within about 4 miles of the sea, as Thundersley is, metal fixings wear faster and gales find any loose ridge or slate.
Do you cover Thundersley?
We do. The survey and report are the same in Thundersley as anywhere else.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance, and details are available on request.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
What will the report tell me?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
Will you repair the leak?
No. We test the membrane and report. The report shows where each breach is for your roofer to repair.
Can every flat roof be tested?
Not every roof is suitable. Certain membranes are conductive, and some build-ups lack a suitable layer below. If your roof will not work, we will say so at the start.
What this survey can’t tell you
Without opening up the roof, some things stay hidden, so a survey has limits:
- Moisture spread under the membrane
- Some conductive membranes
- Water entering through details rather than the membrane
