About our electronic leak detection in Brockley
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work and parts may need to be lifted. We will 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. If testing isn’t possible, we’ll say so. If you are worried about patched roofs that still leak and a flat roof leak that can’t be traced, a survey will tell you what’s going on, on roof terraces and balconies, liquid-applied waterproofing and green roofs alike.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Brockley, access is agreed with whoever manages the roof ahead of the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

How it works
A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from every safe vantage point, photograph what we find and record our findings for the written report. Most visits take as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. For a visit in Brockley, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it is safe.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before the survey
- Mention any parking restrictions on your street
- Agree roof access with the managing agent if it’s shared
- Have any paperwork from past roof work to hand

A quick phone call is normally the easiest start: phone 07833 053749 or send us an email. You’ll have a price before anything is arranged.
Advice
Leave it or get it looked at?
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. Many older London roofs have only old felt under the slates, or no underlay at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.

Electronic leak detection around Brockley
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. With Queen's House about 2.4 miles north-east, Brockley sits in an area with a long building history. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
Anyone responsible for a site like Beecroft Garden Primary will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. The streets around a church such as Church of St Hilda are frequently among the oldest in a place, and if your home is one of the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Questions from Brockley
Is parking a problem for a survey in Brockley?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is my home in Brockley listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Let us know what you know about the roof and we’ll confirm suitability.
What happens after the survey?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are frequently shared, so we need permission from the freeholder or managing agent. We inspect only the parts we’re allowed to reach.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Is Brockley in your area?
Yes, we do. We carry out electronic leak detection in Brockley.
How the survey changes by roof type
Single-ply membranes
ELD often works on single-ply membranes but it depends on the product and layers.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers but it depends on the layers.
When you need someone else
Some things cannot be seen without opening up the roof, so a survey has limits:
- Parts of the roof covered by fixed equipment
- Some conductive membranes
- The extent of water in the insulation
If in doubt, phone 07833 053749 or send us an email and we’ll suggest the right survey. The full list of what we check.

What we’re asked to look at in Brockley
Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
It is worth booking a survey if you’ve seen:
- Water coming in under a flat roof
- Leaks at pipes, outlets or fixings
- Holes left by work on the roof
- Breaches hidden under paving or planting
Controlled parking zones are common in London, so mention any permit rules for Brockley, along with any off-street space.
Before booking any roof surveyor
- Their insurance cover
- How soon the report will arrive
- What experience they bring
- Their drone registration, if they fly one
What a survey costs
The price reflects the time and kit the roof needs. That comes down to:
- Any need for thermal images or a drone flight
- Height and safe access
- How many separate roofs there are, such as extensions, dormers and garages
- Features like valleys, chimneys, dormers and parapets
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the exact price before booking.
