Electronic leak detection in Margaretting
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see, so your roofer can repair them. The results come in a report with photos. We are often asked to look into leaks at pipes, outlets or fixings and patched roofs that still leak, across roof terraces and balconies, green roofs and liquid-applied waterproofing.
In a small place like Margaretting, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
Findings are set out part by part, from the coverings down to the gutters, each with a short note and a photograph. You’ll see the good as well as the bad.

Why it is worth a survey now in Margaretting
Patching where you think the leak is often misses it. Testing shows where the membrane is actually breached. Older cottages and farmhouses around Margaretting can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.

Margaretting: your questions answered
Do you cover Margaretting?
Yes, Margaretting is within the area we cover. We cover the whole of London and South East England. You can phone 07833 053749 or send us an email with the address and a few details.
Is Margaretting within the area you cover?
Yes, Margaretting is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is the repair part of the test?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
Can you survey at the weekend?
We survey seven days a week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
Does the weather affect the survey?
Light rain does not typically stop a survey. High wind or heavy rain can stop drone flights and make roof access unsafe, so we will agree a new date if the weather is not suitable.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. We’ll talk about access when booking.

How the survey works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect as long as needed for the roof’s area and construction, which we set out in the quote. In a hamlet or village like Margaretting, a postcode doesn’t always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Getting ready for the survey

How to book
Getting a price is simple: just call 07833 053749 or use the contact form, tell us about the property and we’ll suggest the right survey. We confirm the price before anything is booked.
Advice
Practical tips
There’s plenty you can do without going near the roof. Here’s what helps most:
- Test new membranes before covering them
- Keep foot traffic on flat roofs to a minimum
- Have roof specifications to hand
- Get leaks traced quickly
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that and other checks can help judge it.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Different roofs, different checks
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We check this first.
Bituminous membranes
Many flat roofs use bitumen-based membranes. The build-up decides which method will work.
What you can safely check yourself
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
What electronic leak detection looks like in Margaretting
Older buildings in Essex often have clay tiles and weatherboarding, alongside plenty of post-war and newer estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. With Hylands about 1.8 miles north-east, Margaretting sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
Anyone responsible for a site like Anglo European School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. Take an older house close to Church of St Margaret: flat-roofed rear additions and dormers added over the years are worth checking. If you let a flat or house near Ingatestone station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
