About our electronic leak detection in Biggin Hill
We carry out electronic leak detection on flat roofs in Biggin Hill and across London and South East England. Testing normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Every roof is quoted on its size and build-up. You get a written report with photos. We survey flat roof membranes, roof terraces and balconies and single-ply roofs, and people most often book us about patched roofs that still leak and leaks at pipes, outlets or fixings.
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 Biggin Hill, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to, and recommendations are put by urgency where it matters.

Prices for electronic leak detection in Biggin Hill
We confirm the exact price before booking. This is what makes a difference:
- How complicated the roof is, with its valleys, chimneys and parapets
- Height and safe access
- If the survey needs thermal imaging or a drone
- Commercial roofs and larger buildings
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Booking your survey
You don’t need to know any roofing terms. Just tell us:
- The type of building and roof, like pitched or flat
- What’s prompted the survey
- Pictures from the garden or a window, if you have them
- Dates you’re working to, like exchange
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, ring 07833 053749 or use the contact form.
Flat and commercial roofs around Biggin Hill
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. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Historic houses such as Down House, about 1.7 miles north-east, show how far back building in the area around Biggin Hill goes. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
Take a building like Oaklands Primary Academy: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Biggin Hill is in London, so parking needs 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 Mark's Church, flat-roofed rear additions and dormers added over the years are worth checking.

Any roof job in Biggin Hill means planning around parking, neighbours and access. That is a good reason to find problems early, while there is time to plan, rather than in a rush after a leak.

For landlords and managing agents
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photos included.
Letting agents often book on a landlord’s behalf, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
How it works
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. A typical survey takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Surveys in Biggin Hill can be booked for any day of the week. London parking is frequently by permit or pay-and-display, so it is useful to know what’s near you. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- 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.
Getting ready for the survey
- Leave side gates unlocked
- If the roof is shared, arrange access with whoever manages the building
- Show us where any leaks or stains appear
Arrange a survey
If you are buying, it’s useful to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply phone 07833 053749 or email us whenever suits you.

Different roofs, different checks
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible but it depends on the layers.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane, which affects testing.
