Electronic leak detection in Langley
Some flat roofs can’t 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, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. Typical surveys look at failed seams and laps and new roofs to check before paving or planting, across flat roof membranes, roof terraces and balconies and green roofs.
Flat roofs on exposed homes in small places like Langley take more wind and rain, which is hard on edges, upstands and joins in the covering. 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. Exposed edges are usually the first part of a flat roof to go.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Prices for electronic leak detection in Langley
Several things affect the price of a survey:
- The roof’s overall size
- Features like valleys, chimneys, dormers and parapets
- Whether thermal imaging or a drone is needed
- Extra roofs, like extensions, dormers or garages
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.
Getting in touch
Before you get in touch, it helps to have:

Questions from Langley
Does a conservation area affect roof work in Langley?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is Langley in the area you cover?
Yes, Langley is within the area we cover. We cover the whole of London and South East England. Just phone 07833 053749 or use the contact form and tell us about the property.
Can you survey at the weekend?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
What do I do with the report?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Do you test for asbestos?
No. We don’t sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
Is the repair part of the test?
No. ELD is testing only. The report shows where each breach is for your roofer to repair.
Can you give me structural calculations?
No. We point out what can be seen, like sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
The survey, step by step
On the day, we begin with a quick chat about the roof and anything that’s worrying you. After that, we check everything we can see safely, from ground level, from windows, in the loft space and by drone where applicable. The survey normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. Rural addresses near Langley can be hard to find from a postcode alone, so a few directions are welcome. 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.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
How to prepare
- Show us where any leaks or stains appear
- Jot down any questions you want answered
- Let us know about parking near the property
Booking a survey
If you are buying, it’s useful to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just phone 07833 053749 or email us when you are ready.
Advice
Landlord and commercial surveys in Langley
We survey roofs for landlords and letting agents as well as homeowners. A photo-illustrated written report gives you a clear record of the flat roof membrane.
Businesses and commercial landlords can book us too. Bigger roofs take more time, and they’re priced for the size.
Why get it checked now?
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first so your roofer knows where to work. For an older or listed building in a place like Langley, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the exact price before booking.

Local flat roofs in Langley
Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent. Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, alongside plenty of post-war and newer estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you own a rental within reach of Audley End station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. The streets around a church such as Church of St John the Evangelist are often among the oldest in a place, and if your house is among the older ones nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
