How electronic leak detection works in Upton Park
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs do not have a suitable layer beneath the membrane. We’ll say if ELD won’t work on your roof before any testing. 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 are often asked to look into new membranes needing a check before handover and repairs that haven’t stopped the leak, on commercial flat roofs, flat roof membranes and green roofs.
On a London roof terrace or a flat roof over a back addition, water frequently 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 Upton Park, the flat roof is often a shared part of the building.
After the visit, you get a written report with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

How we price electronic leak detection
The price reflects the time and kit the roof needs. The main factors are:
- The use of thermal imaging or a drone
- How big the roof is
- The shape of the roof and its details
- The number of roofs, including extensions and garages
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before you book.
What we need to know
There is no need for technical words. It is enough to let us know:
- Your timetable, like an exchange date
- What’s prompted the survey
- The type of building and roof, such as pitched or flat
- Any photos you have, taken from ground level or a window
Most bookings start with a short call: call 07833 053749 or send us an email and we’ll ask a few questions about the roof. You will have a price before anything is arranged.
What else we do in Upton Park
What happens if roof problems are left?
Patching where you think the leak is often misses it. Testing shows where the membrane is actually breached. 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.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You’ll know the price for the job before you book.

Electronic leak detection around Upton Park
About 2.7 miles east lies Eastbury Manor House, a reminder of how long the area around Upton Park has been built on. 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 any change of roofing material on a listed home needs checking with the council first. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Take a building like St Edward's Catholic Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you let a flat or house near Woodgrange Park station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Near you in Upton Park
In Upton Park, that means homes and buildings near Lister Community School, The Service for Deaf and Partially Hearing Children and West Ham Park and the streets around them. The nearest railway station is Woodgrange Park station, about 1.2 miles north.

Rented homes, blocks and businesses
We survey roofs for landlords and letting agents as well as householders. The report gives you a dated record of the flat roof membrane, with photographs.
If the property is let, the agent or a tenant can let us in, at a time agreed ahead of time. We survey on any day of the week, which can make access easier.
How it works
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents as you book.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before the survey
- For flats, make sure roof access has been agreed
- Make sure pets are kept safely away
- Leave a clear route to the loft
How to book
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, call 07833 053749 or email us.

Useful tips for Upton Park property owners
Here are a few things we’d tell any owner, before and after a survey:
- Note where leaks show inside and when
- Use boards when working on the roof
- Get leaks traced quickly
- Avoid repeated repairs without finding the cause
The report records each breach location with photos. Your roofer uses it to carry out repairs.
Don’t leave a flat roof leak running. Water under a membrane can spread.
