Electronic leak detection in Rainham, Greater London
We take a careful look at the flat roof membrane at your property in Rainham, and put it all in a written report with photos.
- Patched roofs that still leak
- Punctures from foot traffic or tools
- Leaks under green or ballasted roofs
Do you need electronic leak detection in Rainham?
When the membrane is buried, holes can’t be seen at all. ELD can work on some covered roofs, depending on the build-up.
Problems we come across often include:
- Leaks showing away from the breach
- Leaks through a covered membrane
- New membranes needing a check before handover
- A flat roof leak that can’t be traced
For a London address like Rainham, it’s useful to know about controlled parking before the day.
Before booking any roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Their insurance cover
- What follow-up you get after the report
- Will the report include photos?
How electronic leak detection works in Rainham
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work and parts may need to be lifted. We talk this through before we quote. Any details of the build-up help, as they show what lies beneath the surface. If testing isn’t possible, we’ll say so. Common reasons to book are a flat roof leak that can’t be traced and leaks through a covered membrane, on liquid-applied waterproofing, roof terraces and balconies and single-ply roofs.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Rainham, the flat roof is frequently a shared part of the building.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photograph where possible, with the urgent items made clear.

Rainham: your questions answered
Do you cover Rainham?
Yes. We work right across London and the South East, and Rainham is part of that. Just phone 07833 053749 or drop us an email and let us know about the property, and we will talk through which survey suits.
Does a conservation area affect roof work in Rainham?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
How long will testing take?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
Do you test for asbestos?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
What is electronic leak detection?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through so we can pinpoint it.
What if it rains on the day?
It can, depending on the survey. Drones can’t fly safely in strong wind or a downpour, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions aren’t right, we’ll talk to you about another date.
Rented homes, blocks and businesses
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Let us know about it when you book and we will plan the survey around it.
Freeholders and residents’ companies use a roof report to plan and budget, putting the urgent items at the top.
How the survey changes by roof type
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Seams and penetrations are typical breach points.
Green and ballasted roofs
Parts of the covering may have to come up. We explain what’s needed when we quote.
The survey, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. If you have questions on the day, just ask. In a London conversion, the way into the roof space is frequently from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Before the survey
- Leave a clear route to the loft
- Tell us about any leaks, stains or damp patches you know of
- Keep pets inside or away from the areas we are looking at
How to book
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or drop us an email whenever suits you.

Flat roofs in Rainham
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. The wider area around Rainham has a long history of building, with Rainham Hall about 0.2 miles west. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
If your house is among the older ones in the streets near Church of St Helen and St Giles, the flat roofs on later extensions tend to wear out long before the main roof. For landlords with property near Rainham (Essex) station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Rainham is about 4 miles south of Romford, in Greater London. Surveys in Rainham work the same way as everywhere we cover: a careful inspection, photographs and a written report. Our Greater London coverage includes Rainham. There is also a page for London.
