Waltham Forest questions
Do you cover Waltham Forest?
Yes, Waltham Forest is one of the places we work. The survey and report are the same in Waltham Forest as anywhere else, and visits run on weekdays and weekends.
How do I find out if my home in Waltham Forest is listed?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Is it a structural engineer’s report?
No. Our survey is not a structural engineer’s report, and it does not include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
How do I book a survey in Waltham Forest?
To book, phone 07833 053749 or send us an email and let us know the address and what you need to know. We will confirm the price and find a day that suits.
Can you test a green or ballasted roof?
In some cases. It depends on the build-up and the layers above the membrane, and some may need lifting. We’ll discuss it before we quote.
What does the report include?
It sets out what we found, why it matters and what we recommend, backed by photographs. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Electronic leak detection in Waltham Forest: what you get
We carry out electronic leak detection on flat roofs in Waltham Forest and across London and the South East. A visit normally takes as long as needed for the size of the roof and how it’s built, which we set out in the quote. Every roof is quoted on its size and build-up. You get a report with photos. If you’re worried about failed seams and laps and punctures from foot traffic or tools, a survey will tell you what’s going on, on single-ply roofs, green roofs and roof terraces and balconies alike.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Waltham Forest, the roof above may belong to the building rather than one flat.
The report is written in plain words, so you don’t need to be a roofer to follow it. Each point is backed by a photograph where possible, with the urgent items made clear.

What else we do in Waltham Forest
Before and after the survey
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Share any drawings of the roof
- Get leaks traced quickly
- Consider ELD before paving or planting goes on
- Keep foot traffic on flat roofs to a minimum
If anything in the report is not clear, ask us. We can talk you through the findings.
Consider testing a new membrane before it is covered. It’s easier to find holes before more layers are added.
Leave it or get it looked at?
Not every leak is in the membrane. Testing shows whether the membrane is breached, so other causes can be checked. In Waltham Forest, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the exact price before booking.
Why us?
- Drone flown under a CAA Flyer ID and Operator ID
- Photographs and a written report every time
- Independent findings on the roof’s condition
- 98% of customers satisfied

How the survey changes by roof type
Liquid-applied waterproofing
Liquid waterproofing has no laps but holes and thin areas can occur. Suitability for ELD depends on the system.
EPDM rubber roofs
Certain rubber membranes are conductive, which can rule out some methods. We’ll tell you if yours is not suitable.
What happens on the day
We do not take risks to get a closer look. We inspect whatever is safely visible, and anything we cannot see is noted in the report. The survey usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. In Waltham Forest, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- First, you let us know about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- Make a note of anything you’d like us to look at
- Check the loft hatch can be reached
- Keep pets out of the way during the survey

Flat roofs in Waltham Forest
The wider area around Waltham Forest has a long history of building, with Forty Hall about 4.7 miles north-west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, 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, often 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. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For businesses in and around places such as Edmonton Green Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts. For a London address like Waltham Forest, it’s useful to know about controlled parking before the day. For landlords with property near Chingford station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Waltham Forest is about 1 mile north-east of Chingford, in Greater London. Whether the building in Waltham Forest is a house, a flat or a commercial unit, the roof can be surveyed on a weekday or at the weekend.

DIY checks: what’s safe
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
