Electronic leak detection to pinpoint holes in flat roof membranes for Teddington, from an experienced roof surveyor. Every survey comes with a written report and photos.

What we’re asked to look at in Teddington
Roofs covered with paving, ballast or planting hide the membrane. Electronic methods can help on some of these roofs, depending on the build-up.
Signs worth acting on include:
- Leaks at pipes, outlets or fixings
- Gaps at membrane joints
- Holes left by work on the roof
- A flat roof leak that cannot be traced
For businesses in and around places like Bentall Centre, a flat roof over a business is out of sight and out of mind until it leaks.

How electronic leak detection works in Teddington
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It can be used to trace an existing leak or check a new membrane before handover. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Let us know about your roof to find out more. Common reasons to book are water coming in under a flat roof and holes around roof penetrations, on single-ply roofs, roof terraces and balconies and green roofs.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Teddington, the roof above may belong to the building rather than one flat.
After the visit, you get a report with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

FAQs for Teddington
Do you cover commercial flat roofs around Teddington?
Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.
Will parking be an issue for a roof survey in Teddington?
It can be, so it is useful to let us know about permits, visitor bays or off-street space as you book. The visit is then planned around what’s available.
Do you test for asbestos?
No. We don’t sample or test for asbestos. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
How quickly is the report sent?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, tell us as you book.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so the freeholder or managing agent needs to agree access. We can only inspect what we’re given access to.
Does this replace a RICS home 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.
Do you carry out surveys on Saturdays and Sundays?
We carry out surveys seven days a week. To find a day that suits you, call 07833 053749 or send us an email.
Electronic leak detection in Teddington: local notes
There are several hotels within about a mile and a half of Teddington, and hotels, like offices and blocks of flats, frequently have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
A roof leak in a hotel or guest house around Teddington means lost rooms as well as repairs. With Strawberry Hill House about 0.8 miles north, the area around Teddington has a long history. Older homes nearby may have later flat-roofed extensions or dormers, often re-covered more than once.

How it works
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photos go into the written report. It usually takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. Many London properties are flats or terraces with no side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know when booking.
- 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.
- A report with photographs shows where each breach is.
How to prepare
- Unlock side gates and any roof access doors
- Let us know about parking before the day
- If you are buying, check with the agent that we can get in
Arrange a survey

Useful tips for Teddington property owners
These tips come from what we see on roofs every week, before and after a survey:
- Stay off the flat roof unless needed
- Do not leave water getting in
- Let us know about the membrane and build-up if you know it
- Clear flat roof outlets regularly
Where the evidence points to walls, copings or rooflights, we will note it, so other causes can be checked.
Consider testing a new membrane before it is covered. Finding breaches is simpler at that stage.
What you can safely check yourself
A DIY look is useful, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level.
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
