Electronic Leak Detection in Russell Hill
A careful look at the flat roof membrane at your property in Russell Hill, and put it all in a photo-illustrated written report.
- Breaches hidden under paving or planting
- Breaches around outlets and penetrations
- Leaks through a flat roof with no obvious cause
What affects the cost of electronic leak detection
What a survey costs depends on the time and equipment it needs. The main factors are:
- Extra roofs, like extensions, dormers or garages
- Building height and the viewpoints available
- How complicated the roof is, with its valleys, chimneys and parapets
- Any need for thermal images or a drone flight
To find out what your survey will cost, call 07833 053749 or email us and let us know about the roof. We’ll confirm the figure before booking.
What to let us know when you contact us
What helps most when you contact us:

- The property’s address and postcode
- Access details, such as a loft hatch or a shared roof
Photos help, if you have them. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, call 07833 053749 or email us.
Electronic leak detection for homes and businesses in Russell Hill
ELD finds breaches in the membrane but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. We’ll tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. Our report keeps that distinction clear. You will also know what to check next. We survey single-ply roofs, commercial flat roofs and green roofs, and people most often book us about stains far from any visible defect and gaps at membrane joints.
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 Russell Hill, access is agreed with whoever manages the roof ahead of the visit. 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. Photos show what each point refers to.

Russell Hill questions
Does a conservation area affect roof work in Russell Hill?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Do you cover commercial flat roofs around Russell Hill?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
Do you work in Russell Hill?
Yes. Russell Hill is part of the area we cover, and the service is the same as everywhere else we work.
Do you carry professional indemnity insurance?
Our cover is professional indemnity plus public liability, and details are available on request.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through so we can pinpoint it.
Do you look in the loft space?
Where it’s relevant to the survey and there’s safe access, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
How long have you been surveying roofs?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.
How the survey works
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. For a visit in Russell Hill, 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. We then look at what can safely be seen from the ground, windows, the loft and, where it’s safe, the roof itself.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Before we arrive
- Leave side gates unlocked
- Point out any leaks or damp patches
- Make a note of anything you’d like us to look at

Related advice
Flat and commercial roofs around Russell Hill
Russell Hill has a number of hotels within about a mile and a half. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. About 3.7 miles east lies Addington Palace, a reminder of how long the area around Russell Hill has been built on. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof.
For businesses in and around places such as St George's Walk, outlets and upstands on commercial flat roofs are the places to check before trouble starts. The streets around a church like St. Paul's are often among the oldest in a place, and if you own one of the older houses nearby, the flat roofs on later extensions tend to wear out long before the main roof. If you look after a building like Wallington Primary Academy, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

For landlords and managing agents
Where a roof is shared: we need access agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the survey around it.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
What you can safely check yourself
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Leave it or get it looked at?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. In Russell Hill, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Dealing with it early is far less disruptive.
