Electronic Leak Detection in Purfleet-on-Thames

- Leaks showing away from the breach
How electronic leak detection works in Purfleet-on-Thames
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. We will tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. You’ll also know what to check next. If you’ve noticed new membranes needing a check before handover and holes left by work on the roof, we can find out what’s behind it, on commercial flat roofs, roof terraces and balconies and liquid-applied waterproofing alike.
Around a smaller place like Purfleet-on-Thames, flat roofs normally cover extensions, garages and dormers. Even a small flat roof can let lots of water into the room below. Knowing the covering and how it was laid tells you what to expect from it. From an upstairs window, look for standing water, splits and edges coming away.
We write the report in plain English, so you do not need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

Flat roofs in Purfleet-on-Thames
Rainham Hall, about 3.1 miles north-west, is one of the historic houses in the wider area around Purfleet-on-Thames. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area. In Essex, older buildings are frequently clay-tiled, many with weatherboarding, alongside a good many post-war and newer estates. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you run a business near Lakeside Shopping Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after. If you live in an older home near St Stephen's Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Purfleet-on-Thames is about 3 miles north of Dartford, in Thurrock. From houses to flats and shops in Purfleet-on-Thames, we can survey the roof. Our area takes in places right across Thurrock. There is also a page for London.

Before and after the survey
From years of surveys, a few habits stand out:
- Consider ELD before paving or planting goes on
- Keep a note of leaks after rain
- Avoid repeated repairs without finding the cause
- Share any drawings of the roof
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
The survey, step by step
After the inspection, everything we found is written up in a report with photographs, sent to you by email. On timing, it normally takes a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting. In a smaller place like Purfleet-on-Thames, parking is seldom the issue; lanes, gates and long drives are worth mentioning. On bungalows and lower roofs, much can be seen from the ground, with the loft showing the underside.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Getting ready for the survey
- Mention any parking restrictions on your street
- Have keys ready for side gates, garages or roof access doors
- Check pets are kept safely away
Arrange a survey
Booking is simple: just ring 07833 053749 or send us an email, let us know about the property and we’ll explain which survey suits. The price is agreed up front.
Advice
Do you need electronic leak detection in Purfleet-on-Thames?
Seams are a common weak point in flat roof waterproofing. A gap that’s hard to see can let water in for months before it shows.
Most people get in touch after spotting something like this:
- Gaps at membrane joints
- Damage from equipment installers
- Stains far from any visible defect
- Leaks through a flat roof with no obvious cause
If you let a flat or house near Purfleet station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
What to check before booking
- What the report includes, and whether it has photographs
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether you can ask questions once you have the report
- How soon the report will arrive
Questions from Purfleet-on-Thames
Does a conservation area affect roof work in Purfleet-on-Thames?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Do you carry out roof surveys in Purfleet-on-Thames?
Yes, Purfleet-on-Thames is one of the places we work. Every survey there gets the same written report with photographs.
Do you take photos of the roof?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
What is electronic leak detection?
A sound membrane blocks the test current, so wherever there is a hole, it passes through. That lets us find breaches that are too small to see.
Will you walk on the roof?
Only where it is safe to do so. We look at everything that can safely be seen: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
Will you check the loft?
Where it’s relevant to the survey and there’s safe access, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
Does ELD work under paving or planting?
In some cases. The layers on top and the build-up below decide it and parts may need to be lifted. We talk this through first.
