What we look for on each type of roof
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible but it depends on the layers.
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Electronic leak detection for homes and businesses in Coalhill
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It can be used to trace an existing leak or check a new membrane before handover. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Let us know about your roof to find out more. We are often asked to look into leaks showing away from the breach and leaks that return after repairs, across liquid-applied waterproofing, green roofs and commercial flat roofs.
In a village or hamlet like Coalhill, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
What you get is a clear record of the flat roof membrane on the day we saw it. It’s useful right away, and a good reference for later.

What else we do in Coalhill
Do you need electronic leak detection in Coalhill?
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
Things that often lead to a survey include:
- Punctures from foot traffic or tools
- Breaches around outlets and penetrations
- Waterproofing to test before it’s covered
- Patched roofs that still leak
If you let a flat or house near Battlesbridge station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Before you book anyone
- Whether the loft is part of the inspection
- How much experience they have with roofs like yours
- What insurance they carry
- What the survey will not cover
What we do, step by step
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 longer on a large roof than a small one, with the construction of the roof playing a part too. Rural addresses near Coalhill can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- First, you tell us about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Preparing for the visit
- Let us know about parking before the day
- Leave a clear route to the loft
- Jot down any questions you want answered
Booking a survey
Photos help, if you have them. Take them safely from ground level or a window. To get started, call 07833 053749 or drop us an email.

Practical tips
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Clear flat roof outlets regularly
- Keep foot traffic on flat roofs to a minimum
- Check new waterproofing before handover
- Ask contractors to protect the membrane
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Do not leave a flat roof leak running. Water under a membrane can spread.

Flat roofs in Coalhill
Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, and plenty of post-war and modern estates besides. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 4.5 miles north lies Danbury Place, a reminder of how long the area around Coalhill has been built on. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof.
If you live in an older home near Church of St Peter, the flat roofs on later extensions tend to wear out long before the main roof.

Your questions about electronic leak detection in Coalhill
Is my home in Coalhill listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you cover Coalhill?
Yes. Our area covers London and South East England, and Coalhill is part of that. Just ring 07833 053749 or drop us an email and tell us about the property.
Will you walk on the roof?
Only if it’s safe. We inspect whatever is safely visible: from the ground, from windows, from inside the roof space, from the roof where it is safe and by drone where it applies. Anything we can’t see is noted in the report.
Do you carry out surveys on Saturdays and Sundays?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you when booking.
Do you use drones?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
Do you look in the roof space?
If there’s a loft and safe access to it, yes. From inside, the underside of the roof often shows damp, staining or daylight that cannot be seen from outside.
Can you survey a shared roof?
Yes, if the freeholder or managing agent agrees access. On a shared roof we can only inspect the parts we are allowed to reach, and the report makes that clear.
