Electronic leak detection in Totteridge
We carry out electronic leak detection on flat roofs in Totteridge and across London and the South East. A visit normally takes as long as needed for the roof’s area and construction, which we’ll explain when we quote. Electronic leak detection is quoted for your roof, because the method depends on the roof. The results come in a written report with photos. If you’ve noticed holes around roof penetrations and gaps at membrane joints, we can find out what’s behind it.
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 Totteridge, the flat roof is often a shared part of the building.
Findings are set out part by part, from the coverings down to the gutters, with a note and a photo for each point. You will see the good as well as the bad.

Totteridge: your questions answered
Does a conservation area affect roof work in Totteridge?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you cover Totteridge?
Yes, Totteridge is within the area we cover. Our area covers London and the South East. You can ring 07833 053749 or use the contact form with the address and a few details.
Is the repair part of the test?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
I live in a flat. Can you survey the roof?
Yes, if whoever owns or manages the building agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
Which method do you use?
The roof decides the method. You will know which method we plan to use before we start.
What do I do with the report?
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.
How much time does ELD need?
The roof’s size and build-up decide how long it takes. You’ll know roughly how long before we start.
What electronic leak detection does not cover
Every survey has limits, and we’d rather be clear about that before booking. Keep these in mind:
- The extent of water in the insulation
- Some conductive membranes
- Carrying out the repair work

What this survey covers
- Green roofs
- Flat roof membranes
- Single-ply roofs
- Roof terraces and balconies
- Liquid-applied waterproofing
- Commercial flat roofs
What we look for on each type of roof
Bituminous membranes
Bituminous roofs often have laps and old repairs where breaches occur. We test where the roof suits it.
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible but it depends on the layers.
Local flat roofs in Totteridge
Wyllyotts Manor, about 4.2 miles north, is one of the historic houses in the wider area around Totteridge. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. 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. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
Parking in Totteridge, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier, as a space near the door can’t be promised. If you live in an older home near St Andrew's Church, flat-roofed rear additions and dormers added over the years are worth checking. If you own a rental within reach of Oakleigh Park station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Totteridge is about 1 mile south-west of Barnet, in Greater London. Surveys in Totteridge work the same way as everywhere we cover: a careful inspection, photos and a written report.

Landlord and commercial surveys in Totteridge
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
Letting agents frequently book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
Leave it or get it looked at?
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole 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. When the stain finally shows, the damage underneath is frequently older than it looks.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

What we do, step by step
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. A typical visit takes a time that depends on the roof’s area and construction, which we set out in the quote. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
How to prepare
- Keep pets out of the way during the survey
- If you are buying, let the agent know when we’re coming
- Show us where any leaks or stains appear
Booking a survey
To book a survey, phone 07833 053749 or drop us an email with the address and what you’d like to know about the roof. We will confirm the price before booking.
Advice
What you can safely check yourself
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
