About our electronic leak detection in Ditton Hill
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. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. We survey flat roof membranes, commercial flat roofs and single-ply roofs, and the problems we are asked to look at most are punctures from foot traffic or tools and leaks through a covered membrane.
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 Ditton Hill, the roof above may belong to the building rather than one flat.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Common roof problems in Ditton Hill
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny but water still finds them.
It’s worth booking a survey if you’ve seen:
- Leaking laps in the waterproofing
- New roofs to check before paving or planting
- Breaches hidden under paving or planting
- Punctures from foot traffic or tools
If you let a flat or house near Surbiton station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Questions to ask before booking
- How much experience they have with roofs like yours
- Whether the loft is part of the inspection
- What the survey won’t cover
- When you’ll get the report
Tips from our surveys
A survey works best with a little help from you, before and after. Tips:
- Test new membranes before covering them
- Don’t keep patching the same spot
- Get leaks traced quickly
- Use boards when working on the roof
If we think the leak isn’t coming through the membrane, the report says so, with a suggestion of what to check next.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
Checking the roof from the ground
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book.
What you can’t do safely is get up close. Roofs are fragile and slippery. That’s where a survey comes in, using safe viewpoints and a drone where applicable.

Honest limits
In fairness, there are limits to any roof survey:
- Water entering through details rather than the membrane
- Parts of the roof covered by fixed equipment
- Repairing the breaches (that’s for your roofer)

Flat roofs in Ditton Hill
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. If your home in Ditton Hill is one of them, bay roofs, hips and later dormers each have their own details. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 2 miles north-west lies Hampton Court Palace, a reminder of how long the area around Ditton Hill has been built on.

FAQs for Ditton Hill
Do you cover Ditton Hill?
We do. Every survey there gets the same written report with photos.

Do I have to be there for the survey?
Someone needs to let us in if we are looking inside or in the loft. We will talk about access when you book.
What’s in the report?
You get our findings in writing, part by part, with photos, finishing with recommendations. The most urgent items are made clear.
Do you survey roofs on blocks of flats?
Yes, if the building owner or managing agent agrees access. We look at the parts we’re given access to.
Will I get photos?
Yes. Photos are part of every report, so you can see each point for yourself.
How many surveys have you done?
We have completed more than 5,000 surveys, over more than 20 years.
The survey, step by step
We do not take risks to get a closer look. Everything that can safely be seen is inspected, and anything we cannot see is noted in the report. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. In a London area like Ditton Hill, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from ground level, windows, the loft and, where it’s safe, the roof itself.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
Preparing for the visit
- Find any records of previous roof work
- Buyers: confirm access with the estate agent or seller
- Leave side gates unlocked
