Electronic leak detection in Herne Hill: what you get
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work, and some may need lifting. We’ll discuss it with you when we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. We will tell you if the roof can’t be tested. We survey green roofs, single-ply roofs and commercial flat roofs, and common reasons people get in touch are leaks showing away from the breach and new roofs to check before paving or planting.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Herne Hill, the roof above may belong to the building rather than one flat.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

How the survey works
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, let us know when booking.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- The breaches are recorded with photographs in a report for your roofer.
Before the survey
- If the roof is shared, arrange access with whoever manages the building
- Unlock side gates and any roof access doors
- Tell us where we can park nearby
Book a survey
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To send them or to book, ring 07833 053749 or drop us an email.

Landlord and commercial surveys in Herne Hill

Local flat roofs in Herne Hill
The wider area around Herne Hill has a long history of building, with Kingswood House about 1.7 miles south. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. There are several hotels within about a mile and a half of Herne Hill, 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.
For an older house near a landmark such as Saint Faith's, the flat roofs on later extensions tend to wear out long before the main roof. If you let a flat or house near North Dulwich station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Prices for electronic leak detection in Herne Hill
Prices vary from roof to roof, for these reasons:
- The size of the roof
- Height and safe access
- Commercial roofs and larger buildings
- The use of thermal imaging or a drone
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. It’s enough to tell us:
- Whether there is a loft hatch, a shared roof or tricky access
- Dates you are working to, such as exchange
- What kind of property and roof it is
- Pictures of the roof from a safe spot, if you have them
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, phone 07833 053749 or use the contact form.
DIY checks: what’s safe
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
Common questions in Herne Hill
Is my home in Herne Hill listed or in a conservation area?
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 Herne Hill, such as hotels?
Yes. As well as homes, we look at flat roofs on offices, hotels, blocks of flats and commercial units. Larger commercial roofs are quoted for the building.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so whoever owns or manages the building needs to agree access. We inspect only the parts we are allowed to reach.
Do you use drones?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We are a CAA-registered drone operator.
What do I do with the report?
The report comes 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 do I book a survey in Herne Hill?
To arrange a survey, call 07833 053749 or send us an email and let us know the address and what you want to find out. We’ll confirm the price and find a day that suits.
Is this a RICS survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.

Why act early in Herne Hill
A visual inspection can miss tiny holes. Electronic testing can find breaches you can’t see by eye where the roof suits it. In Herne Hill, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the exact price before booking.

Signs you need electronic leak detection in Herne Hill
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole, so tracing it by eye is difficult.
These are some of the problems a survey can pick up:
- Leaks through a flat roof with no obvious cause
- New membranes needing a check before handover
- Repairs that haven’t stopped the leak
- Breaches around outlets and penetrations
For businesses in and around places like Surrey Quays Shopping Centre, a flat roof over a business is out of sight and out of mind until it leaks.
Questions to ask before you book
- What the report includes, and whether it has photos
- What they will not be able to tell you
- How long they’ve been surveying roofs
- Whether the loft is part of the inspection
