Electronic leak detection for homes and businesses in Duckett's Green
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work, and some may need lifting. We talk this through before we quote. Any details of the build-up help because they show what’s under the surface. We’ll tell you if the roof cannot be tested. Typical surveys look at patched roofs that still leak and leaks under green or ballasted roofs, on green roofs, commercial flat roofs and single-ply roofs.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. In Duckett's Green, 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.
Findings are set out part by part, from the main slopes down to the gutters and outlets, with a note and a photo for each point. It records what’s sound as well as what is not.

Can I check my roof myself?
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.

What affects the cost of electronic leak detection
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- The number of roofs, including extensions and garages
- Whether thermal imaging or a drone is needed
- How complicated the roof is, with its valleys, chimneys and parapets
- House, block, shop or office
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Helping us price your survey
To price your survey accurately, we’ll ask about:
- When you need the report by
- Access details, such as a loft hatch or a shared roof
- What made you get in touch
- Your postcode, so we can check access and travel
Our phone lines are open seven days a week. To book or ask a question, call 07833 053749 or drop us an email.
Flat and commercial roofs around Duckett's Green
With Bruce Castle about 1.2 miles north-east, Duckett's Green sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. If your home in Duckett's Green 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.
For businesses in and around places such as The Mall Wood Green, the flat roofs over shops and commercial units are worth checking before a leak, not after. Take a building like St John Vianney RC Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Parking in Duckett's Green, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier, as a space near the door cannot be promised.

What we do, step by step
The visit typically 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. All told, expect as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when booking.
- 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.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
How to prepare
- Make sure pets are kept safely away
- For flats, make sure roof access has been agreed
- Let us know about any leaks, stains or damp patches you know of
How to book
Getting a price is simple: just call 07833 053749 or use the contact form and give us some details about the property and we’ll explain which survey suits. The price is agreed up front.

Your questions about electronic leak detection in Duckett's Green
Does a conservation area affect roof work in Duckett's Green?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Will parking be an issue for a roof survey in Duckett's Green?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. That way the visit can be planned around it.
Will you walk on the roof?
Only where it’s safe to do so. We inspect whatever is safely visible: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
Which method do you use?
The roof decides the method. You will know which method we plan to use before we start.
How experienced are you?
Over 5,000 surveys so far, across 20+ years of surveying roofs.
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.
What do I do with the report?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Surveys for landlords and agents in Duckett's Green
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Larger roofs take longer.
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client, photos included.
Different roofs, different checks
Bituminous membranes
Bituminous roofs often have laps and old repairs where breaches occur. We test where the roof suits it.
Inverted and paved roofs
Paving and terraces cover the membrane. Suitability depends on the layers.
Before and after the survey
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Use boards when working on the roof
- Keep outlets clear of debris
- Have roof specifications to hand
- Record dates and spots where water appears
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.
