What electronic leak detection looks like in Puddle Dock
Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. The wider area around Puddle Dock has a long history of building, with Hare Hall about 4.1 miles north-west. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Puddle Dock is in London, so parking needs planning: let us know about parking bays, permits or a driveway when booking, as a space near the door cannot be promised. If you own a rental within reach of Upminster station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

About our electronic leak detection in Puddle Dock
There are different ELD methods. Low-voltage methods usually need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof, and we’ll explain our choice. We will say if your roof doesn’t suit either method at the outset. If you’ve noticed punctures from foot traffic or tools and new membranes needing a check before handover, we can find out what’s behind it, on roof terraces and balconies, liquid-applied waterproofing and green roofs alike.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Puddle Dock, access is agreed with whoever manages the roof ahead of the visit. Plant bases, rooflights and cable entries are all places where water can get in.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t.

How we price electronic leak detection
Prices vary from roof to roof, and it comes down to:
- Extra roofs, like extensions, dormers or garages
- Height and safe access
- The type of building, from a house to a block or an office
- The roof’s overall size
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for your roof before you book.
What we need to know
A little information up front helps. It is useful to include:
- What made you get in touch
- The address and postcode of the property
- Dates you’re working to, like exchange
- Access details, like a loft hatch or a shared roof

What we’re asked to look at in Puddle Dock
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak for months before it shows.
These are some of the problems a survey can pick up:
- Leaks under green or ballasted roofs
- Patched roofs that still leak
- Leaking laps in the waterproofing
- Breaches around outlets and penetrations
The streets around a church such as Moor Lane Church are frequently among the oldest in a place, and if yours is one of the older homes nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Questions to ask before booking
- How much experience they have with roofs like yours
- Their insurance cover
- What they will not be able to tell you
- Their drone registration, if they fly one
Roof by roof
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. Whether ELD suits them depends on the build-up.

Your questions about electronic leak detection in Puddle Dock
Is Puddle Dock in the area you cover?
We do. The survey and report are the same in Puddle Dock as anywhere else.
Does a conservation area affect roof work in Puddle Dock?
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.
What insurance do you have?
We hold professional indemnity and public liability insurance, for every survey we carry out.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
How long does electronic leak detection take?
It depends on the size of the roof and its build-up. You will know roughly how long before we start.
How do I book a survey in Puddle Dock?
It is easiest to phone 07833 053749 or drop us an email. Let us know the address and a little about the roof, and we will point you to the right survey. We survey on weekdays and at weekends.
Will you walk on the roof?
Only where it’s safe to do so. We check everything that can be seen safely: from ground level, from windows, from inside the roof space, from the roof where it is safe and by drone where applicable. Anything we cannot see is noted in the report.
What happens on the day
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photos go into the written report. It typically takes a length of time set by the membrane area and the build-up, which we set out in the quote. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- You tell us 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.
Before we arrive
- Leave side gates unlocked
- Let us know about parking near the property
- For a flat or shared roof, check access with whoever owns or manages the building
Booking a survey

Advice
Why act early in Puddle Dock
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That is a good reason to find problems early, while there’s time to plan, rather than in a rush after a leak.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.

Before and after the survey
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Find the breach before more patching
- Test new membranes before covering them
- Don’t leave water getting in
- Have roof specifications to hand
If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer and other checks can help judge it.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
