About our electronic leak detection in Kennington
Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. If your roof isn’t suitable, we will tell you at the start. Any details you have about the membrane and build-up help us decide, like drawings or specifications. It avoids arranging a test that cannot give results. We survey single-ply roofs, commercial flat roofs and flat roof membranes, and the problems we are asked to look at most are leaks through a flat roof with no obvious cause and new membranes needing a check before handover.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. In Kennington, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
The report is written in plain words, so it makes sense without any roofing background. Photos show what each point refers to, and recommendations are put in order of urgency where relevant.

Electronic leak detection in Kennington: local notes
About 1.7 miles north-west lies Buckingham Palace, a reminder of how long the area around Kennington has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Kennington has a number of hotels within about a mile and a half. If you look after one, a leak through a flat roof can put a room out of use.
Landlords with a home close to Vauxhall station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. A roof leak in a hotel or guest house around Kennington means lost rooms as well as repairs.
Kennington is about 2 miles south-west of London, in Greater London. Roofs in Kennington get the same thorough look as anywhere else in Greater London. Kennington is one of the towns and villages in Greater London where we work for electronic leak detection.

How we price electronic leak detection
Not every roof costs the same to survey, and it comes down to:
- The number of roofs, including extensions and garages
- Whether it is a home or a commercial building
- Height and safe access
- If the survey needs thermal imaging or a drone
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
Booking your survey
If you can, have these to hand when you contact us:
- Pictures of the roof from a safe spot, if you have them
- The kind of building and roof involved
- How the loft is reached, if there is one
- The property’s address and postcode
Every survey is priced before it’s booked, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, call 07833 053749 or email us.
Kennington questions
Does a conservation area affect roof work in Kennington?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you look at commercial flat roofs near Kennington, such as hotels?
Yes, we cover commercial roofs as well as homes. Access to the roof is sorted out with whoever manages the building before the day.
Will you check the loft?
If there is a loft and safe access to it, yes. The roof space can show things the outside can’t, such as damp timbers, staining or daylight.
Will you go up on the roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the loft space and a drone where applicable.
Do you take photos of the roof?
Yes, every report has them. Pictures sit next to the findings they show, which makes the report easy to follow.
Can you give me structural calculations?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
What if it rains on the day?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. We will rearrange with you if the weather isn’t right.
Why get it checked now?
ELD before paving, ballast or planting goes on is simpler. Once layers are added, finding a breach is harder. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

What we do, step by step
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from every safe viewpoint, take photographs as we go and record our findings for the written report. Most visits take a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. In a London conversion, the way into the roof space is often from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- You tell us about the roof and where water is showing.
- 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.
- A report with photos shows where each breach is.
Before the survey
- If the roof is shared, arrange access with whoever manages the building
- Unlock side gates and any roof access doors
- Move anything stored under the loft hatch
Booking a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or use the contact form when you’re ready.
Advice
What we cannot see
We only report whatever is safely visible on the day, so some things are outside what a survey can do:
- Sections we can’t safely access
- Leaks from plumbing or windows
- Build-ups without a suitable layer below

Roof types and parts we check
- Roof terraces and balconies
- Commercial flat roofs
- Single-ply roofs
- Liquid-applied waterproofing

What we are asked to look at in Kennington
Repeated leaks after repairs suggest the real breach hasn’t been found. Electronic testing helps pinpoint it.
Problems we come across often include:
- Patched roofs that still leak
- Leaks through a flat roof with no obvious cause
- Failed seams and laps
- Breaches hidden under paving or planting
Take an older house close to Calvary Church of God in Christ: the joins between later flat roofs and the old walls are where problems typically start.
What to check before booking
- Will they check the loft as well as the outside?
- Which limits apply to the survey
- Their report turnaround times
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
