Electronic Leak Detection in Coney Hall
Electronic leak detection in Coney Hall from an independent, experienced roof surveyor. Over 5,000 surveys and 20+ years behind us across London and South East England.
- Holes left by work on the roof
- Leaks showing away from the breach
- Leaks through a flat roof with no obvious cause
How electronic leak detection works in Coney Hall
ELD can be carried out in more than one way. Low-voltage testing is typically done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. If neither method suits your roof, we’ll tell you at the outset. Common reasons to book are leaking laps in the waterproofing and repairs that haven’t stopped the leak, across flat roof membranes, green roofs and roof terraces and balconies.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in Coney Hall shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

- Green roofs
DIY checks: what’s safe
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we look at the roof.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Signs you need electronic leak detection in Coney Hall
Joints and laps in a membrane can fail over time. A gap that’s hard to see can let water in for months before it shows.
Things that frequently lead to a survey include:
- New roofs to check before paving or planting
- Gaps at membrane joints
- Damage from equipment installers
- Leaks showing away from the breach
Parking in Coney Hall, as in most of London, takes a little planning: let us know about parking bays, permits or a driveway when you book.
Questions to ask before booking
- Which viewpoints they use to see the roof
- Which limits apply to the survey
- What insurance they carry
- Whether the loft space is looked at, where there is one
Flat and commercial roofs around Coney Hall
Historic houses such as Addington Palace, about 1.2 miles south-west, show how far back building in the area around Coney Hall goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Outer London has plenty 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.
Take a building like Forest Academy: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Shop and office owners around The Mall may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts.

London parking is often by permit or pay-and-display, so it helps 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.

Coney Hall questions
Can parking be tricky for a visit in Coney Hall?
It depends on the street. If Coney Hall has controlled parking where you are, a visitor permit is the easiest answer.
Is my home in Coney Hall listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
What’s the best way to book?
Simply ring 07833 053749 or drop us an email with the address. We’ll ask a few questions, confirm the price and agree a date.
Which method do you use?
We choose the method that suits the roof. You’ll know which method we plan to use before we start.
Can you survey a shared roof?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from the freeholder or managing agent. We inspect only the parts we are allowed to reach.
Will I get photos?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
What if it rains on the day?
Light rain is usually fine; heavy rain and wind are different. Strong wind or a downpour can make access unsafe and ground a drone, and we’d agree another day.
What happens if roof problems are left?
Repairs in the wrong place leave the leak in place. Testing shows where the membrane is actually breached. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.

Different roofs, different checks
Bituminous membranes
Bituminous roofs often have laps and old repairs where breaches occur. Testing depends on the roof.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Suitability for ELD depends on the system.
