Electronic Leak Detection in Middle Park
Electronic leak detection to pinpoint holes in flat roof membranes in Middle Park, carried out by an experienced roof surveyor. You get a clear written report with photos.
- Leaks at pipes, outlets or fixings
- Damage from equipment installers
- New roofs to check before paving or planting
Practical tips
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Tell us about the membrane and build-up if you know it
- Note where leaks show inside and when
- Get leaks traced quickly
- Consider ELD before paving or planting goes on
If we think the leak isn’t coming through the membrane, the report says so, so other causes can be checked.
Ask trades working on the roof to protect the membrane when fitting equipment. Check the roof after they’ve finished.
Electronic leak detection in Middle Park
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. If testing is not possible, we’ll say so. We are frequently asked to look into breaches around outlets and penetrations and new roofs to check before paving or planting, on roof terraces and balconies, liquid-applied waterproofing and single-ply roofs.
Offices, shops and blocks of flats across London often 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 Middle Park, access is agreed with whoever manages the roof before the visit. Plant bases, rooflights and cable entries are all places where water can get in.
Where we can’t see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

What we cannot see
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Repairing the breaches (that’s for your roofer)
- Water entering through details rather than the membrane
- Parts of the roof covered by fixed equipment

What else we do in Middle Park
Middle Park: your questions answered
Is Middle Park in the area you cover?
We do. Every survey there gets the same written report with photographs.
Does a conservation area affect roof work in Middle Park?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
How fast do I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. To get a quote, call 07833 053749 or send us an email.
Which days do you carry out surveys?
We carry out surveys seven days a week. To arrange a date, call 07833 053749 or email us.
What if it rains on the day?
It can, depending on the survey. Drones can’t fly safely in strong wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We’ll rearrange with you if the weather isn’t right.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
What we do, step by step
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. After that, we check everything we can see safely. The survey normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a London area like Middle Park, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at everything that’s safely in view from ground level, windows, the loft and, where it is safe, the roof itself.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before the survey
- Have keys ready for side gates, garages or roof access doors
- Have any paperwork from past roof work to hand
- If you’re buying, let the agent know when we’re coming
Booking a survey
A quick phone call is normally the easiest start: ring 07833 053749 or use the contact form and we’ll ask a few questions about the roof. You will have a price before anything is arranged.
Related advice
Rented homes, blocks and businesses
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps when budgeting.
If the property is let, the agent or a tenant can let us in. Surveys run on weekdays and at weekends, which helps when tenants work during the week.
Should I look at the roof myself first?
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.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
Local flat roofs in Middle Park
With Eltham Palace about 0.4 miles east, Middle Park sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of 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. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you run a business near Lewisham Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts. The streets around a church like Church of St Saviour are often among the oldest in a place, and if your house is among 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. If you own a rental within reach of Mottingham station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

What we look for on each type of roof

ELD frequently works on single-ply membranes, depending on the type and build-up.
EPDM rubber roofs
Certain rubber membranes are conductive which can limit electronic testing. We will tell you if yours is not suitable.
