How electronic leak detection works in South Norwood
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair rather than guessing. Repair costs are not part of the report, so your roofer prices the work. A retest after repairs can check the work, where the roof still suits the method. You get a photo-illustrated written report. We survey liquid-applied waterproofing, commercial flat roofs and single-ply roofs, and the problems we are asked to look at most are leaks showing away from the breach and holes around roof penetrations.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in South Norwood, the roof above may belong to the building rather than one flat.
Every survey ends with a written report, with photographs, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

South Norwood: your questions answered
Do you cover South Norwood?
Yes, South Norwood is within the area we cover. Our area covers London and the South East. You can ring 07833 053749 or email us with the address and a few details, and we’ll talk through which survey suits.
Can parking be tricky for a visit in South Norwood?
It rarely stops a survey, but it is worth planning. Let us know what parking is available nearby, and the visit is planned around it.
What does electronic leak detection do?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Does electronic leak detection work on all membranes?
That depends on the roof’s membrane and layers. Let us know what you know about the roof and we’ll check whether ELD will work.
Will I get photos?
Yes. Photos are part of every report.
How long does electronic leak detection take?
It depends on the size of the roof and its build-up. You will know roughly how long before we start.
What’s the best way to book?
To arrange a survey, phone 07833 053749 or drop us an email and let us know the address and what you’d like to know. We’ll confirm the price and agree a day with you.
What we do, step by step
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, take photographs as we go and record our findings for the written report. It usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. From the street, a London terrace normally shows only its front slope or parapet, so a visit in South Norwood moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Tell us who holds the keys.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before we arrive
- Buyers: confirm access with the estate agent or seller
- If the roof is shared, arrange access with whoever manages the building
- Let us know about parking near the property

Tips that help
Here are a few things we’d tell any owner:
- Do not leave water getting in
- Keep a note of leaks after rain
- Share any drawings of the roof
- Consider ELD before paving or planting goes on
You receive a report showing where each breach was found, with photographs. Your roofer uses it to carry out repairs.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Checking the roof from the ground
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.

What else we do in South Norwood
Why get it checked now?
Some breaches are too small to see. ELD picks up breaches a visual check might miss, on suitable membranes. 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 frequently older than it looks.

Flat and commercial roofs around South Norwood
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. With Kingswood House about 2.2 miles north, South Norwood sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
Controlled parking zones are common in London, so mention any permit rules for South Norwood. Take an older house close to Church of St Mark: the joins between later flat roofs and the old walls are where problems usually start. Take a building like St Mark's Church of England Primary Academy: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

What affects the price in South Norwood
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- How complicated the roof is, with its valleys, chimneys and parapets
- The use of thermal imaging or a drone
- The type of building, from a house to a block or an office
- The height of the building and how the roof can safely be seen
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.
