Why it’s worth a survey now in Little Walden
Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first so your roofer knows where to work. Around Little Walden, older homes often have old roof timbers, and water through a failed covering can rot timber if it is left.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.

Electronic leak detection in Little Walden: what you get
ELD finds breaches in the membrane, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. We’ll 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’ll point you to the likely next step. We survey liquid-applied waterproofing, green roofs and flat roof membranes, and people most often book us about damp inside with no sign on the roof and leaks through a covered membrane.
Somewhere as small as Little Walden, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access ahead of time. Garages and outbuildings are easy to forget, so mention any you want included when you book.
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.

Checking the roof from ground level
What you cannot do safely is get up close. Roofs are fragile and slippery. That part is for a survey.
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us as you book and it will help the survey.
When to book a survey in Little Walden
Joints and laps in a membrane can fail over time. A gap that is hard to see can let water in for months before it shows.
It is worth booking a survey if you’ve seen:
- Leaks showing away from the breach
- Holes around roof penetrations
- Punctures from foot traffic or tools
- Repairs that haven’t stopped the leak
If you live in an older home near St John, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
What to check before booking
- When you will get the report
- How long they’ve been surveying roofs
- Whether VAT is in the quoted price
- Whether they hold professional indemnity and public liability insurance
Electronic leak detection around Little Walden
Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, alongside a good many post-war and newer estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. The wider area around Little Walden has a long history of building, with Audley End House about 2.5 miles south-west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
Landlords with a home close to Great Chesterford station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint. For site and facilities teams at buildings such as Saffron Walden County High School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Little Walden is about 2 miles north of Saffron Walden, in Essex. Anywhere in Little Walden, we can carry out electronic leak detection at your property, on a weekday, Saturday or Sunday. Little Walden is one of the towns and villages in Essex where we work. We also survey roofs in Chelmsford.

Before and after the survey
You don’t need to be a roofer to help. What helps most:
- Keep foot traffic on flat roofs to a minimum
- Act on new leaks promptly
- Test new membranes before covering them
- Use boards when working on the roof
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
How the survey works
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like Little Walden can have low, tight loft spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Before the survey
- Tell us about any leaks, stains or damp patches you know of
- Mention any parking restrictions on your street
- For a flat or shared roof, check access with the freeholder or managing agent
Book a survey
Every survey is priced before it is booked, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, phone 07833 053749 or email us.

Little Walden: your questions answered
Does a conservation area affect roof work in Little Walden?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. 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.
Will you come out to Little Walden?
Yes, Little Walden is covered. We survey roofs across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
How much does electronic leak detection cost?
Each roof is quoted on its size and build-up. Tell us about the roof and where it leaks, and call 07833 053749 or drop us an email for a quote.
Is this an asbestos survey?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
Does the weather affect the survey?
A survey can normally go ahead in light rain, and it can even help show where water is getting in. Strong wind or a downpour can stop drone flights and make roof access unsafe, so if conditions are not right we’ll arrange another day with you.
How do you choose the testing method?
We choose the method that suits the roof. You will know which method we plan to use before we start.
Do you use drones?
Yes, where it’s applicable. 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.

What affects the price in Little Walden
Not every roof costs the same to survey, and it comes down to:
- How many separate roofs there are, such as extensions, dormers and garages
- House, block, shop or office
- The size of the roof
- How tall the building is and how easy the roof is to see
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the exact price before booking.
What to tell us when you contact us
There’s no need for technical words. It’s enough to let us know:

- The property’s address and postcode
- Whether there is a loft hatch, a shared roof or tricky access
- Where water is showing inside, if it is
To book a survey, call 07833 053749 or drop us an email and let us know the address and what’s prompted the survey. You’ll know the price before anything is booked.
