Crow's Green Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes for Crow's Green and the rest of Essex. Surveys run on any day of the week.
- Failed seams and laps
- Leaks through a covered membrane
- Leaks showing away from the breach
How electronic leak detection works in Crow's Green
You get a report showing the location of each breach, with photos. Your roofer can then repair those points instead of hunting for the leak. Repair costs are not part of the report, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. If you are worried about holes left by work on the roof and repairs that haven’t stopped the leak, a survey will tell you what’s going on, on liquid-applied waterproofing, commercial flat roofs and green roofs alike.
Older buildings in small places like Crow's Green may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

Before and after the survey
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Don’t keep patching the same spot
- Share any drawings of the roof
- Get leaks traced quickly
- Keep outlets clear of debris
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
What we look for on each type of roof
Liquid-applied waterproofing
Pinholes in a coating can let water through. Where the roof suits it, testing can find them.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane and that changes how testing works.
What we cannot see
It is a careful look at the flat roof membrane, not the whole story. The main limits are:
- Carrying out the repair work
- Parts of the roof covered by fixed equipment
- Roofs whose membrane or build-up isn’t suitable

What else we do in Crow's Green
What we do, step by step
We look at the roof from outside and, where it’s relevant and there’s safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. Older rural homes like those around Crow's Green can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely, and anything we can’t see is noted.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Have keys ready for side gates, garages or roof access doors
- Leave a clear route to the loft
- Jot down any questions you want answered
Getting a price
If you are buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or email us when you’re ready.

Electronic leak detection around Crow's Green
Listing and conservation areas can both shape what roof work is allowed on an older home. The council is the place to check, along with Historic England’s list. Weatherboarded walls and clay tile roofs are typical of older Essex buildings, with post-war and more recent estates making up much of the newer housing. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If your house is among the older ones in the streets near Church of St James, 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 let a flat or house near Braintree station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

What you can safely check yourself
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
What you cannot do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That’s where a survey comes in.
FAQs for Crow's Green
Is my home in Crow's Green listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you carry out roof surveys in Crow's Green?
Yes, Crow's Green is one of the places we work. The survey and report are the same in Crow's Green as anywhere else, and visits run on weekdays and weekends.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. Roofs over flats are often shared, so we need permission from the building owner or managing agent. We inspect only the parts we’re allowed to reach.
How experienced are you?
We’ve been surveying roofs for over 20 years and have carried out more than 5,000 surveys.
Does electronic leak detection work on all membranes?
ELD does not suit every roof. Some membranes conduct electricity, and some build-ups lack a suitable layer below. If your roof will not work, we will say so before testing.
Do you use drones?
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.
Does ELD work under paving or planting?
In some cases. It depends on the build-up and the layers above the membrane, and some may need lifting. We talk this through first.
Surveys for landlords and agents in Crow's Green
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.
