Any of our surveys can be booked by landlords, agents and building managers in Greenwich. For a price for a let property or a block, call 07833 053749 or send us an email.
Electronic leak detection for homes and businesses in Greenwich
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It can be used to trace an existing leak or check a new membrane before handover. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Tell us about your roof to find out more. If you’ve noticed leaks that return after repairs and punctures from foot traffic or tools, a survey will tell you what’s going on, whatever the roof.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. In Greenwich, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are frequently felt or asphalt, newer ones rubber or GRP.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

When you need someone else
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Parts of the roof covered by fixed equipment
- Build-ups without a suitable layer below
- Leaks from walls, copings or rooflights
If you are not sure which survey you need, call 07833 053749 or send us an email and we will give you a straight answer before booking. The full list of what we check.

Common questions in Greenwich
How do I find out if my home in Greenwich 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.
Can parking be tricky for a visit in Greenwich?
It can be, so it’s useful to tell us about permits, visitor bays or off-street space as you book. That way the visit can be planned around it.
How do you choose the testing method?
We choose the method that suits the roof. You will know which method we plan to use before we start.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so we need permission from whoever owns or manages the building. We inspect only the parts we’re allowed to reach.
Do you work in Greenwich?
Yes. Our area covers London and South East England, and that includes Greenwich.
Does someone need to be in?
That depends on the survey. Inside the building and in the loft, we need someone to let us in; we’ll agree the details when booking.
Do you use drones?
Yes, where it’s applicable. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Signs you need electronic leak detection in Greenwich
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole which makes it hard to find by looking.
A survey can pick up problems such as:
- Patched roofs that still leak
- Damp inside with no sign on the roof
- Breaches around outlets and penetrations
- New membranes needing a check before handover
For hotels and guest houses around Greenwich, a roof problem found early is far less disruptive than one found by a guest.
Questions to ask before you book
- What follow-up you get after the report
- What the survey won’t cover
- How long the report takes to arrive

Electronic leak detection in Greenwich: local notes
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. If your home in Greenwich is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. There are several hotels within about a mile and a half of Greenwich, and hotels, like offices and blocks of flats, often have flat roofs. If you look after one, a leak through a flat roof can put a room out of use.
Take an older house close to St Mary's Church: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Queen's House lies about 0.2 miles north-west, so building around Greenwich goes back a long way. If your home is older, its flat-roofed extension or dormer may be on its second or third covering.
Greenwich is about 4 miles east of London, in Greater London. Whether the building in Greenwich is a house, a flat or a commercial unit, we can survey the roof. Across Greater London, we cover Greenwich.
We survey roofs across the SE10, SE3 and SE8 postcode area for electronic leak detection. Local streets include Cade Road, Webb Road and Creek Road, all of which we cover. Greenwich sits on or near the A2203 and A2211, which makes travel easy. If you’re just outside Greenwich, we cover Maze Hill (1 mile north-east), Vanbrugh Park Estate (1 mile east), Blackheath (1 mile south-east), Westcombe Park (1 mile east) and Isle of Dogs (1 mile north-west). We also work in nearby towns such as London (4 miles west), City of Westminster (7 miles west), Marylebone (7 miles west), Kensington (9 miles west), St Pancras (6 miles north-west) and Shoreditch (5 miles north-west).
What’s near Greenwich
We work in homes and buildings around The Plume of Feathers pub, John Roan School and Royal School of Naval Architecture and Marine Engineering, among other places. You will also find Island Gardens (0.6 miles north-west) and St. Paul's (1.1 miles west). There is a railway station in Greenwich itself: Maze Hill station. Well-known places in the area include Greenwich Castle (within half a mile south-west) and Greenwich District Hospital (0.5 miles north-east). Green spaces nearby include Tower Hill and Creekside Discovery Centre.
The survey, step by step
You do not need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will take it from there. The survey itself takes as long as needed for the roof’s area and construction, which we’ll explain when we quote. Surveys in Greenwich can be booked for any day of the week. 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.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
How to prepare
- Dig out any old roof reports or invoices
- Let us know about parking before the day
- Note where any stains or damp appear
Getting a price
If you have photos of the roof, send them over. Take them safely from ground level or a window, and please do not climb up for a closer look. To send them or to book, phone 07833 053749 or send us an email.
Advice
How the survey changes by roof type
Single-ply membranes
Many offices and units have single-ply roofs. Seams and penetrations are typical breach points.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
What affects the cost of electronic leak detection
What a survey costs depends on the time and equipment it needs. The main factors are:
- The height of the building and how the roof can safely be seen
- Extra roofs, like extensions, dormers or garages
- The type of building, from a house to a block or an office
- Chimneys, valleys, parapets and other details
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.
Getting in touch
Getting the details right at the start saves time. Please include:
- The reason for the survey, such as buying, a leak or storm damage
- Your postcode, so we can check access and travel
- How the loft is reached, if there is one
- Dates you are working to, such as exchange
A quick phone call is typically the easiest start: ring 07833 053749 or email us. The price is agreed before a date is set.
