Electronic leak detection in Crow Green, Essex
Know where you stand with the flat roof membrane before you decide what to do next. We carry out electronic leak detection in Crow Green, with photographs and a clear written report.
- Leaks showing away from the breach
- Repairs that haven’t stopped the leak
- A flat roof leak that can’t be traced
Common roof problems in Crow Green
Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
We are often asked to look at:
- Waterproofing to test before it is covered
- Leaks under green or ballasted roofs
- Leaks through a flat roof with no obvious cause
- Leaks at pipes, outlets or fixings
Anyone responsible for a site like Larchwood Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

- How much experience they have with roofs like yours
Electronic leak detection in Crow Green
ELD finds breaches in the membrane but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. We will tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. We will point you to the likely next step. Common reasons to book are leaks that return after repairs and holes around roof penetrations, across roof terraces and balconies, single-ply roofs and flat roof membranes.
Some older homes in villages like Crow Green are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later.

What happens on the day
We will ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. For a village or hamlet like Crow Green, the journey is planned beforehand: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Before the survey
- Jot down any questions you want answered
- Buyers: confirm access with the estate agent or seller
- For flats, make sure roof access has been agreed

Your questions about electronic leak detection in Crow Green
Do you carry out roof surveys in Crow Green?
Yes, Crow Green is within the area we cover. Our area covers London and South East England. You can ring 07833 053749 or send us an email with the address and a few details.
Do you cover smaller places like Crow Green?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
Will you repair the leak?
No. ELD is testing only. The report shows where each breach is for your roofer to repair.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys.
What’s the best way to book?
To book, ring 07833 053749 or drop us an email with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
Can you find leaks on a covered flat roof?
In some cases. The layers on top and the build-up below decide it, and some may need lifting. We will discuss it before we quote.

Flat and commercial roofs around Crow Green
Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, and a good many post-war and modern estates besides. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Ingatestone Hall, about 4.4 miles east, is one of the historic houses in the wider area around Crow Green. If your house is among the older ones, expect a mix of original materials and later repairs on the roof.
The streets around a church such as Trinity Church are often among the oldest in a place, and if you own one of the older houses nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you let a flat or house near Shenfield station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Practical tips
Most of what helps is simple and safe from the ground. Our suggestions:
- Do not leave water getting in
- Share any drawings of the roof
- Note where leaks show inside and when
- Find the breach before more patching
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
What this survey cannot tell you
Without opening up the roof, some things stay hidden, so a survey has limits:
- Leaks from walls, copings or rooflights
- Sections we cannot safely access
- Roofs whose membrane or build-up isn’t suitable
If in doubt, call 07833 053749 or email us and we will recommend the right survey before booking. What a survey covers and does not.
What we check
- Single-ply roofs
- Commercial flat roofs
- Green roofs
- Roof terraces and balconies
- Liquid-applied waterproofing
- Flat roof membranes
What happens if roof problems are left?
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. Older and listed buildings around Crow Green may need consent and matching materials for repairs, so leaving a defect until it is urgent leaves less time to plan.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for your roof before you book.
