What electronic leak detection looks like in De Beauvoir Town
Within a mile and a half or so of De Beauvoir Town there are several hotels, and like offices and blocks, hotels frequently sit under flat roofs. If you look after one, a leak through a flat roof can put a room out of use. 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. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Anyone responsible for a site like Our Lady and St Joseph Catholic Primary School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. Landlords with a home close to Dalston Junction station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Electronic leak detection in De Beauvoir Town: what you get
ELD finds breaches in the membrane, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing will not show on the test. If the evidence points elsewhere, we’ll say so. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. We will point you to the likely next step. If you’ve noticed waterproofing to test before it’s covered and a flat roof leak that can’t be traced, we can find out what’s behind it, whatever the roof.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in De Beauvoir Town, 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.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

How the survey works
The visit usually starts outside and finishes in the loft: outside views come first, then the roof space if there is safe access. In total, it takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. In De Beauvoir Town, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
Before we arrive
- Show us where any leaks or stains appear
- Agree roof access with the managing agent if it’s shared
- Let us know about parking near the property

- Commercial roofs and larger buildings
- How many separate roofs there are, such as extensions, dormers and garages

How the survey changes by roof type
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Laps and fixings are where holes frequently appear.
Bituminous membranes
Older felt roofs often have seams and patches where breaches occur. We test where the roof suits it.
Questions from De Beauvoir Town
Is my home in De Beauvoir Town listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Do you look at commercial flat roofs near De Beauvoir Town, such as hotels?
Yes, commercial buildings, hotels included, are part of the work. Access to the roof is sorted out with whoever manages the building before the day.
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, which shows us where the hole is.
What if it rains on the day?
A survey can normally go ahead in light rain, and it can even help show where water is getting in. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so if conditions are not right we will arrange another day with you.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys.
How much time does ELD need?
It usually takes a length of time set by the size of the roof and how it’s built, which we set out in the quote.
Do you use drones?
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.
Tips from our surveys
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Test new membranes before covering them
- Record dates and spots where water appears
- Get leaks traced quickly
- Find the breach before more patching
If anything in the report is not clear, ask us. We’ll explain what was found and what it means.
Check contractors protect the waterproofing when they work up there. Check the roof after they’ve finished.
Do you need electronic leak detection in De Beauvoir Town?
Holes in a membrane frequently come from feet, tools or debris. Many are tiny but water still finds them.
Most people get in touch after spotting one of these:
- Leaks at pipes, outlets or fixings
- Damage from equipment installers
- Stains far from any visible defect
- Breaches hidden under paving or planting
The streets around a church such as Church of St Peter are often among the oldest in a place, and if you own one of the older houses nearby, the flat roofs on later extensions tend to wear out long before the main roof.
What to check before booking
- Is there a chance to talk the report through?
- How they plan to inspect the roof safely
- Will they check the loft as well as the outside?
- Whether VAT is added on top
What we cannot see
We only report whatever is safely visible on the day, so there are some things a survey can’t cover:
- Fixing the holes we find
- The extent of water in the insulation
- Parts of the roof covered by fixed equipment
