Electronic Leak Detection in Lamarsh
Electronic leak detection to pinpoint holes in flat roof membranes around Lamarsh, with findings in writing and pictures to back them up. Weekday and weekend visits available.
- Leaks through a covered membrane
- Damage from equipment installers
- Waterproofing to test before it is covered
How the survey changes by roof type
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. Whether ELD suits them depends on the build-up.
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible, depending on the build-up.
Electronic leak detection for homes and businesses in Lamarsh
Some flat roofs cannot be tested electronically. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. If your roof isn’t suitable, we’ll tell you at the start. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It saves a wasted visit. We survey roof terraces and balconies, single-ply roofs and commercial flat roofs, and people most frequently book us about a flat roof leak that can’t be traced and leaks showing away from the breach.
Flat roofs on exposed homes in small places like Lamarsh take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, typically 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.
What you get is a clear record of the flat roof membrane on the day we saw it. It’s useful straight away, and a good reference for later, for instance when you want to check whether anything has changed.

What electronic leak detection looks like in Lamarsh
In Essex, older buildings are often clay-tiled, many with weatherboarding, and plenty of post-war and modern estates besides. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Gainsborough's House, about 3.7 miles north, is one of the historic houses in the wider area around Lamarsh. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
If you let a flat or house near Bures station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you own one of the older houses in the streets near Church of the Holy Innocents, flat-roofed rear additions and dormers added over the years are worth checking.
Lamarsh is in Essex. From houses to flats and shops in Lamarsh, we can survey the roof on a weekday or at the weekend. Lamarsh is one of the places in Essex we cover for electronic leak detection. Our Chelmsford page covers surveys nearby.
Here we cover the CO8 postcode area for electronic leak detection. We cover properties on Alphamstone Road, Henny Road and Bell Hill. If you are just outside Lamarsh, we cover Alphamstone (1 mile west), Bures Green (1 mile east), Bures (1 mile south-east), Mount Bures (2 miles south) and Cross End (2 miles south-west). Further out, we also cover Colchester (9 miles south-east), Braintree (11 miles south-west), Witham (14 miles south), Camulodunum (9 miles south-east), Halstead (6 miles south-west) and Greenstead (10 miles south-east).
Landmarks near Lamarsh
We work in homes and buildings around The Lamarsh Lion pub. The nearest railway station is Bures station, roughly 1.3 miles south-east of the centre. Nearby you’ll also find Sudbury Museum (3.5 miles north) and Mount Bures (2.1 miles south). Green spaces nearby include Cornard Mere.
What happens on the day
There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. The survey itself takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. Somewhere like Lamarsh needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Getting ready for the survey
- Check the loft hatch can be reached
- If you’re buying, let the agent know when we are coming
- Tell us about any leaks, stains or damp patches you know of
Arrange a survey
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, phone 07833 053749 or drop us an email.

What electronic leak detection doesn’t cover
A survey is a careful look at the flat roof membrane, but it can’t do everything. Its limits include:
- Moisture spread under the membrane
- Sections we can’t safely access
- Water entering through details rather than the membrane
If in doubt, ring 07833 053749 or use the contact form and we will point you to the right survey. What our survey covers.
What this survey covers
- Flat roof membranes
- Roof terraces and balconies
- Green roofs
- Single-ply roofs
- Commercial flat roofs
- Liquid-applied waterproofing
Why it’s worth a survey now in Lamarsh
ELD before paving, ballast or planting goes on is simpler. Once layers are added, finding a breach is harder. Older and listed buildings around Lamarsh may need consent and matching materials for repairs, so leaving a defect until it is urgent leaves less time to plan.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Why book with us
- We hold a CAA Flyer ID and Operator ID
- Surveys seven days a week
- Insured for professional indemnity and public liability
- Drones and thermal imaging where applicable
How we price electronic leak detection
Prices vary from roof to roof, for these reasons:
- The shape of the roof and its details
- Any need for thermal images or a drone flight
- House, block, shop or office
- How tall the building is and how easy the roof is to see
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
What we need to know
What helps most when you contact us:
- What made you get in touch
- Any stains, drips or damp patches you’ve seen indoors
- Your postcode, so we can check access and travel
- What kind of property and roof it is
If you have photos of the roof, send them over. Take them safely from the ground or a window; never climb up to get a better view. To send them or to book, ring 07833 053749 or drop us an email.

Common questions in Lamarsh
Is Lamarsh within the area you cover?
Yes, Lamarsh is covered. We work right across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does a conservation area affect roof work in Lamarsh?
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.
What happens next?
You receive the written report by email, with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Will you check the loft?
Where it’s relevant to the survey and there’s safe access, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
Can you survey in bad weather?
Light rain is usually fine; heavy rain and wind are different. Strong wind or a downpour can make access unsafe and ground a drone, and we’d agree another day.
Are you structural engineers?
No. We note visible signs such as sagging or deflection, but we’re not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.
