Tufnell Park Electronic Leak Detection
Know where you stand with the flat roof membrane before you spend money on it. We carry out electronic leak detection in Tufnell Park, with photos and a clear written report.
- Stains far from any visible defect
- Leaks through a flat roof with no obvious cause
- Leaks that return after repairs
Electronic leak detection in Tufnell Park: what you get
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work and parts may need to be lifted. We will discuss it with you when we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. If testing isn’t possible, we’ll say so. We’re often asked to look into punctures from foot traffic or tools and new membranes needing a check before handover, on single-ply roofs, roof terraces and balconies 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 block or conversion in Tufnell Park, the flat roof is often a shared part of the building.
Every survey ends with a written report, with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Electronic leak detection in Tufnell Park: local notes
With Witanhurst about 1.2 miles north-west, Tufnell Park sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. 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 Tufnell Park is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Landlords with a home close to Upper Holloway station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. For site and facilities teams at buildings such as Eleanor Palmer Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. The streets around a church such as Church of St Benet and All Saints are frequently among the oldest in a place, and if yours is one of the older homes nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

What else we do in Tufnell Park
What you can safely check yourself
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where it applies.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
What we do, step by step
The visit has one job: to see as much of the flat roof membrane as can safely be seen and record it clearly. Notes and photos go into the written report. The visit normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. From the street, a London terrace typically shows only its front slope or parapet, so a visit in Tufnell Park moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before the survey
- Make sure the loft hatch can be reached
- Let us know about any leaks, stains or damp patches you know of
- Dig out any old roof reports or invoices
Booking a survey
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, call 07833 053749 or email us with the address and the days you’d prefer.
Advice
For landlords and managing agents
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client.
If you own several properties, surveys can be booked for more than one address. To arrange surveys for several addresses, phone 07833 053749 or email us.
Before and after the survey
Small things make a difference. Our tips:
- Don’t let outlets block
- Check new waterproofing before handover
- Keep foot traffic on flat roofs to a minimum
- Share any drawings of the roof
If we think the leak isn’t coming through the membrane, the report says so, so other causes can be checked.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
Questions from Tufnell Park
Is Tufnell Park in the area you cover?
We do. The survey and report are the same in Tufnell Park as anywhere else.
Is parking a problem for a survey in Tufnell Park?
It depends on the street. If Tufnell Park has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Does ELD include fixing the breach?
No. We test the membrane and report. The report shows where each breach is for your roofer to repair.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
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.
How do I book a survey in Tufnell Park?
It’s easiest to ring 07833 053749 or send us an email. Give us the address and a few details about the roof. Surveys run seven days a week.
Is my roof suitable for ELD?
ELD does not suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. We’ll tell you if yours isn’t suitable at the start.
Different roofs, different checks
EPDM rubber roofs
EPDM rubber roofs often last 30–50 years, but can still be punctured.
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Honest limits
It is useful to know what a survey won’t do before you book:
- Moisture spread under the membrane
- Leaks from walls, copings or rooflights
- Some conductive membranes
