About our electronic leak detection in Harringay
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it’s covered. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Let us know about your roof to find out more. We survey commercial flat roofs, flat roof membranes and green roofs, and common reasons people get in touch are repairs that haven’t stopped the leak and leaks through a flat roof with no obvious cause.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Harringay, access is agreed with whoever manages the roof before the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
The report works through the roof section by section, from the coverings down to the gutters. It records what’s sound as well as what is not.

What we do, step by step
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey usually takes a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. London terraces rarely offer a view of the whole roof from one spot, so in Harringay 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, tell us who can let us into the shared parts.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Getting ready for the survey
- Make a note of anything you’d like us to look at
- If it is not your property yet, arrange access through the agent
- Dig out any old roof reports or invoices

What happens if roof problems are left?
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss, on suitable membranes. Any roof job in Harringay means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.

Questions from Harringay
Does a conservation area affect roof work in Harringay?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Will parking be an issue for a roof survey in Harringay?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. The visit is then planned around what’s available.
Can you test a green or ballasted roof?
On some roofs, yes. What sits on the membrane affects the method, so we check the build-up first.
Do I have to be there for the survey?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
Do you use drones?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We’re a CAA-registered drone operator.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys, across London and South East England.
What happens next?
You will receive the report 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.

Tips from our surveys
Over many surveys, some simple habits stand out as worth the effort:
- Share any drawings of the roof
- Do not keep patching the same spot
- Keep outlets clear of debris
- Stay off the flat roof unless needed
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Make sure contractors protect the waterproofing when fitting equipment. Have the roof looked at after other work.

Electronic leak detection in Harringay: local notes
With Bruce Castle about 1.6 miles north-east, Harringay sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you own a rental within reach of Harringay Green Lanes station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For businesses in and around places such as The Mall Wood Green, outlets and upstands on commercial flat roofs are the places to check before trouble starts. If your home is one of the older ones in the streets near St Paul's Harringay, flat-roofed rear additions and dormers added over the years are worth checking.
