Electronic leak detection in Hoxton: what you get
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. The results come in a report with photos. Typical surveys look at leaking laps in the waterproofing and leaks that return after repairs, on roof terraces and balconies, liquid-applied waterproofing and single-ply roofs.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. In Hoxton, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
We write the report in plain English, so you don’t need to be a roofer to follow it. Each point is backed by a photo where possible, and recommendations are put with the most urgent first where relevant.

What happens if roof problems are left?
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first so your roofer knows where to work. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.

Flat and commercial roofs around Hoxton
With Mansion House about 1.4 miles south, Hoxton 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 any change of roofing material on a listed home needs checking with the council first. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. 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’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For hotels and guest houses around Hoxton, a roof problem found early is far less disruptive than one found by a guest. If you live in an older home near Church of St Anne with St Columba, the flat roofs on later extensions tend to wear out long before the main roof. If you run a business near Hackney Walk, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

FAQs for Hoxton
Is parking a problem for a survey in Hoxton?
It can be, so it’s useful to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Is my home in Hoxton listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is this a RICS survey?
No. We look at the roof, not the whole building, and it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
Will you photograph what you find?
Yes, every report has them. Pictures sit next to the findings they show.
How much does electronic leak detection cost?
Each roof is quoted on its size and build-up. Send us details of the roof. Just ring 07833 053749 or send us an email for a quote.
How do you choose the testing method?
We choose the method that suits the roof. We will explain why when we quote.
What a survey costs
Prices vary from roof to roof, for these reasons:
- Commercial roofs and larger buildings
- Whether thermal imaging or a drone is needed
- Chimneys, valleys, parapets and other details
- Roof area
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for the job before booking.
Helping us price your survey
We will normally ask about:
- What made you get in touch
- Any marks or damp showing indoors
- Whether there is a loft hatch, a shared roof or tricky access
- What kind of property and roof it is
A quick phone call is normally the easiest start: ring 07833 053749 or send us an email, and we’ll ask about the building and what you need. The price is agreed before a date is set.
Different roofs, different checks
Single-ply membranes
Many offices and units have single-ply roofs. Laps and fixings are where holes often appear.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane and that changes how testing works.
Before and after the survey
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Make sure trades protect the waterproofing
- Do not leave water getting in
- Stay off the flat roof unless needed
- Let us know about the membrane and build-up if you know it
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
What happens on the day
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It normally takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
How to prepare
- Make sure we can get to the back of the property
- Clear the way to the loft hatch
- Note where any stains or damp appear
How to book
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. Otherwise, simply call 07833 053749 or email us whenever suits you.
