About our electronic leak detection in Belvedere
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves and some roofs do not have a suitable layer beneath the membrane. If your roof is not suitable, we’ll tell you at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. We survey liquid-applied waterproofing, roof terraces and balconies and single-ply roofs, and common reasons people get in touch are failed seams and laps and new membranes needing a check before handover.
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 block or conversion in Belvedere, the flat roof is frequently a shared part of the building.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

How the survey changes by roof type
Liquid-applied waterproofing
Liquid waterproofing has no laps, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.
Inverted and paved roofs
Paving and terraces cover the membrane. Whether it can be tested depends on the build-up.
The survey, step by step
Before we start, let us know why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit typically takes a length of time set by the roof’s area and construction, which we’ll explain when we quote. In Belvedere, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We start with what you know about the roof and the leak.
- 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
- Check we can get to the back of the property
- Keep pets inside or away from the areas we’re looking at
- If you are buying, check with the agent that we can get in
Arrange a survey
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 email us whenever suits you.
Advice
Your questions about electronic leak detection in Belvedere
Does a conservation area affect roof work in Belvedere?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Do you carry out roof surveys in Belvedere?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
What do I do with the report?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Do you carry professional indemnity insurance?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
Do you test for asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
Will you fly a drone over my roof?
Where it helps and it’s safe, yes. Whether we can fly on the day depends on the weather and the airspace rules. We hold a CAA Flyer ID and Operator ID.

Signs you need electronic leak detection in Belvedere
Joints and laps in a membrane can fail over time. A gap that’s hard to see can let water in for months before it shows.
Typical things we’re asked to look at include:
- Leaks showing away from the breach
- Punctures from foot traffic or tools
- Leaks that return after repairs
- Breaches around outlets and penetrations
Take an older house close to Parish Church of All Saints: flat-roofed rear additions and dormers added over the years are worth checking.

- When you’ll get the report
- Do they have a CAA Flyer ID and Operator ID for drone work?

Electronic leak detection in Belvedere: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 2.3 miles south-west lies Red House, a reminder of how long the area around Belvedere has been built on. 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.
If you own a rental within reach of Belvedere station, the flat roof over a let home is worth a look before it becomes a tenant complaint. As a London address, Belvedere can be tricky for parking: a visitor permit or a nearby bay makes the day easier, as a space near the door cannot be promised.
Belvedere is about 3 miles east of Plumstead, in Greater London. Houses, flats, blocks and commercial buildings in Belvedere can all book electronic leak detection, with a written report and photographs every time. Belvedere is one of the places in Greater London where we work for electronic leak detection. Our London page covers surveys nearby.

Before and after the survey
A survey works best with a little help from you, before and after. Some tips:
- Avoid repeated repairs without finding the cause
- Test new membranes before covering them
- Make sure trades protect the waterproofing
- Keep outlets clear of debris
If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer, and moisture readings can help.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
Landlords, agents and block managers in Belvedere
Landlords and agents in Belvedere book surveys as well as householders. The report gives you a dated record of the flat roof membrane, with photos, useful for planning maintenance.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Checking the roof from ground level
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry.
