How electronic leak detection works in Becontree
ELD can be carried out in more than one way. Low-voltage testing is normally done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof and we explain which we will use. We’ll say if your roof does not suit either method at the outset. If you are worried about failed seams and laps and leaks under green or ballasted roofs, a survey will tell you what’s going on.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Becontree, the roof above may belong to the building rather than one flat.
What you get is a clear record of the flat roof membrane on the day we saw it. It is useful straight away, and a good reference for later.

Useful tips for Becontree property owners
From years of surveys, a few habits stand out:
- Check new waterproofing before handover
- Share any drawings of the roof
- Check trades protect the waterproofing
- Stay off the flat roof unless needed
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Ask trades working on the roof to protect the membrane when fitting equipment. Have the roof looked at after other work.
The survey, step by step
We check the roof from outside and, where it is relevant and there is safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey usually 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 often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Otherwise, the visit in Becontree runs like any other.
- 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.
Getting ready for the survey
- If you are buying, check with the agent that we can get in
- Keep pets inside or away from the areas we are looking at
- Clear the way to the loft hatch

Advice
Landlords, agents and block managers in Becontree
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.

Becontree questions
Is Becontree in the area you cover?
We do. Every survey there gets the same written report with photographs.
How do I find out if my home in Becontree is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Does the weather affect the survey?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions are not right, we will talk to you about another date.
Does ELD include fixing the breach?
No. We test the membrane and report. You get the breach locations with photos for your roofer to repair.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email.
What happens after the survey?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules. We’re a CAA-registered drone operator.
What we look for on each type of roof
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Whether it can be tested depends on the build-up.
Liquid-applied waterproofing
Liquid waterproofing has no laps but holes and thin areas can occur. Whether ELD works depends on the coating and build-up.

Flat roofs in Becontree
Eastbury Manor House, about 2.1 miles south-west, is one of the historic houses in the wider area around Becontree. Older homes in the wider area often have features worth a closer look, such as 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. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For site and facilities teams at buildings like St Joseph's Catholic Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you own a rental within reach of Chadwell Heath station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

When to book a survey in Becontree
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
We are frequently asked to look at:
- Damp inside with no sign on the roof
- Patched roofs that still leak
- Breaches around outlets and penetrations
- Punctures from foot traffic or tools
Becontree is in London, so parking needs planning: let us know about parking bays, permits or a driveway when you book, as a space near the door can’t be promised.
Before booking anyone
- Will the report include photos?
- Their track record with similar roofs
- Whether any drone flown is registered with the CAA
- Whether the price includes VAT

- Parts of the roof covered by fixed equipment
- Water entering through details rather than the membrane
- The extent of water in the insulation
