Landlords and agents in Heath Park book surveys as well as homeowners. A written report with photos gives you a clear record of the flat roof membrane, which helps you plan work between tenancies.
How electronic leak detection works in Heath Park
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current that passes through the membrane only where there’s a breach. It can find holes too small to spot by eye, so your roofer can repair them. The results come in a report with photos. We survey liquid-applied waterproofing, single-ply roofs and commercial flat roofs, and the problems we are asked to look at most are leaks through a flat roof with no obvious cause and new roofs to check before paving or planting.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Heath Park, the roof above may belong to the building rather than one flat.
Every survey ends with a written report, with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

DIY checks: what’s safe
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.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
Signs you need electronic leak detection in Heath Park
Holes in a membrane often come from feet, tools or debris. Some are too small to see, but still let water through.
Most people get in touch after spotting something like this:
- Stains far from any visible defect
- Leaking laps in the waterproofing
- Breaches around outlets and penetrations
- Waterproofing to test before it’s covered
If you let a flat or house near Gidea Park station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Choosing a roof surveyor
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Their track record with similar roofs
- Whether the loft space is looked at, where there is one
- Whether they hold professional indemnity and public liability insurance
What this survey can’t tell you
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Some conductive membranes
- Carrying out the repair work
- How wet the insulation is
If in doubt, call 07833 053749 or send us an email and we’ll recommend the right survey before you book. What our survey covers.
Roof types and parts we check
- Roof terraces and balconies
- Liquid-applied waterproofing
- Commercial flat roofs
- Flat roof membranes
- Green roofs
- Single-ply roofs
How it works
There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. A typical survey takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Heath Park runs like any other.
- First, we confirm which roof areas are included.
- 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.
How to prepare
- Check the loft hatch can be reached
- Point out any leaks or damp patches
- Find any records of previous roof work

Heath Park: your questions answered
Do you cover commercial flat roofs around Heath Park?
Yes. As well as homes, we check flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you’ll get a quote based on the building.
Can parking be tricky for a visit in Heath Park?
It rarely stops a survey, but it is worth planning. Tell us what parking is available nearby, and the visit is planned around it.
Can you inspect my roof with a drone?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
Is it a structural engineer’s report?
No. Our survey is not a structural engineer’s report, and it does not include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
What happens next?
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.
Do I need to be at home?
That depends on the survey. For inside areas and the loft space, someone has to give us access; we’ll agree the details when you book.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.

Tips from our surveys
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Record dates and spots where water appears
- Find the breach before more patching
- Do not leave water getting in
- Limit access to the roof
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
