Electronic leak detection in Bounds Green: 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. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a written report with photos of each breach found. We survey commercial flat roofs, single-ply roofs and flat roof membranes, and the problems we’re asked to look at most are a flat roof leak that can’t be traced and leaks showing away from the breach.
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, and each fails in its own way. Which one is on a roof in Bounds Green shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

What you can safely check yourself
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
The one thing to avoid is getting up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where it applies.
What we cannot see
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Fixing the holes we find
- Sections we can’t safely access
- Leaks from walls, copings or rooflights
Not sure which survey suits your roof? You can phone 07833 053749 or drop us an email and we’ll tell you. The full list of what we check.
Roof types and parts we check
- Green roofs
- Commercial flat roofs
- Roof terraces and balconies
- Flat roof membranes
- Single-ply roofs
- Liquid-applied waterproofing
Different roofs, different checks
Bituminous membranes
ELD is often possible on bituminous membranes though the layers below matter.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers, depending on the build-up.
Prices for electronic leak detection in Bounds Green
What a survey costs depends on the time and equipment it needs. That comes down to:
- How big the roof is
- The use of thermal imaging or a drone
- Extra roofs, like extensions, dormers or garages
- Commercial roofs and larger buildings
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 your roof before booking.
What we need to know
Here’s what helps us most when you contact us:
- The kind of building and roof involved
- Where water is showing inside, if it is
- When you need the report by
- Photos of the roof, taken safely from ground level or a window
A quick phone call is normally the easiest start: ring 07833 053749 or email us, and we’ll ask about the building and what you need. You will have a price before anything is arranged.

How the survey works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes a time that depends on the roof’s area and construction, which we’ll explain when we quote. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that is the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Bounds Green runs like any other.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Tell us about any leaks, stains or damp patches you know of
- Tell us about parking before the day
- Make sure the loft hatch can be reached
Arrange a survey
You can call us seven days a week. To book or ask a question, phone 07833 053749 or send us an email.

Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. If your home in Bounds Green is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. About 2.2 miles east lies Bruce Castle, a reminder of how long the area around Bounds Green has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
For site and facilities teams at buildings like Bounds Green Infant School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. For a London address like Bounds Green, it helps to know about controlled parking before the day. If your house is among the older ones in the streets near St Barnabas Greek Orthodox Church, the joins between later flat roofs and the old walls are where problems normally start.

FAQs for Bounds Green
Can parking be tricky for a visit in Bounds Green?
Parking in Bounds Green, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Does a conservation area affect roof work in Bounds Green?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Can you find leaks on a covered flat roof?
On some roofs, yes. What sits on the membrane affects the method so we look at the roof first.
Is the repair part of the test?
No. ELD is testing only. You get the breach locations with photos so your roofer can fix them.
How long will testing take?
It depends on the size of the roof and its build-up. You will know roughly how long before we start.
Do you use drones?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We’re a CAA-registered drone operator.
