About our electronic leak detection in Millwall
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or check a new membrane before handover. We quote for each roof based on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. We’re frequently asked to look into leaks under green or ballasted roofs and holes left by work on the roof, on commercial flat roofs, liquid-applied waterproofing and flat roof membranes.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Millwall, the roof above may belong to the building rather than one flat.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Tips that help
A survey works best with a little help from you, before and after. Tips:
- Have roof specifications to hand
- Make sure trades protect the waterproofing
- Check new waterproofing before handover
- Keep a note of leaks after rain
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
What a survey costs
What a survey costs depends on the time and equipment it needs. The main factors are:
- Whether thermal imaging or a drone is needed
- The height of the building and how the roof can safely be seen
- The shape of the roof and its details
- Extra roofs, like extensions, dormers or garages
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Booking your survey
A little information up front helps. It’s useful to include:
- Dates you’re working to, like exchange
- What kind of property and roof it is
- Any marks or damp showing indoors
- Photos of the roof, taken safely from the ground or a window
To arrange a survey, ring 07833 053749 or use the contact form with the address and what you’d like to know about the roof. You will know the price before anything is booked.
What we are asked to look at in Millwall
When the membrane is buried, holes can’t be seen at all. Electronic methods can help on some of these roofs though it depends on the layers.
These are some of the problems a survey can pick up:
- Leaks that return after repairs
- Holes around roof penetrations
- Damp inside with no sign on the roof
- Leaks under green or ballasted roofs
If you run a business near Surrey Quays Shopping Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling.
Questions to ask before booking
- Their drone registration, if they fly one
- Whether you get a written report with photos
- Whether the price includes VAT
- Which parts of the roof they’ll actually see
What we do, step by step
Photos are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. A typical visit takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. From the street, a London terrace typically shows only its front slope or parapet, so in Millwall we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, let us know who can let us into the shared parts.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before the survey
- Gather any invoices or paperwork from past roof work
- Tell us about any leaks, stains or damp patches you know of
- For flats, make sure roof access has been agreed

Questions from Millwall
Do you cover commercial flat roofs around Millwall?
Yes. As well as homes, we look at flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you’ll get a quote based on the building, and roof access is agreed with you before the visit.
Does a conservation area affect roof work in Millwall?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you test for asbestos?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
How do I arrange electronic leak detection in Millwall?
The quickest way is to phone 07833 053749 or drop us an email. Give us the address and some details about the roof, and we’ll take it from there. Surveys run seven days a week.
What do I do with the report?
We email you the written report with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you when you book.
Do you climb onto every roof?
Only if it’s safe. We inspect whatever is safely visible: from the ground, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. Anything we can’t see is noted in the report.
Different roofs, different checks
Green and ballasted roofs
ELD is easier on a new roof before it is covered.
EPDM rubber roofs
Certain rubber membranes are conductive which can limit electronic testing. We will tell you if yours isn’t suitable.
Electronic leak detection in Millwall: local notes
With Queen's House about 0.9 miles south-east, Millwall sits in an area with a long building history. If your house is among 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. Within a mile and a half or so of Millwall there are several hotels, and hotels, like offices and blocks of flats, frequently have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
If you own a rental within reach of Deptford station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take a building like Harbinger Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
