How electronic leak detection works in Langenhoe
Our ELD testing covers flat roofs in Langenhoe and the rest of London and the South East. A visit usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Every roof is quoted on its size and build-up. The results come in a written report with photos. We survey flat roof membranes, liquid-applied waterproofing and commercial flat roofs, and people most often book us about failed seams and laps and holes around roof penetrations.
Some older homes in villages like Langenhoe 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. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

The survey, step by step
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like Langenhoe can have low, tight loft spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- Mention any parking restrictions on your street
- For a flat or shared roof, check access with the building owner or managing agent
- If you’re buying, let the agent know when we’re coming
Book a survey

Local flat roofs in Langenhoe
Langenhoe is within about 2 miles of the coast, so there is more wind and more salt in the air than further inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. Layer Marney Tower, about 4.9 miles west, is one of the historic houses in the wider area around Langenhoe. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
If you own a rental within reach of Wivenhoe station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Anyone responsible for a site like Langenhoe Community Primary School and Pre-School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
Langenhoe is about 4 miles south of Colchester, in Essex. Langenhoe is one of many places we visit across Essex. Our area takes in places right across Essex. Chelmsford is in our area too.

We also cover Abberton (1 mile north), Fingringhoe (1 mile north-east), Berechurch (2 miles north), East Donyland (2 miles north-east) and High Park Corner (2 miles north-east).

What we’re asked to look at in Langenhoe
Holes in a membrane often come from feet, tools or debris. Some are too small to see but water still finds them.
These are some of the problems a survey can pick up:
- Water coming in under a flat roof
- Damp inside with no sign on the roof
- Damage from equipment installers
- Gaps at membrane joints
If your home is one of the older ones in the streets near Church of St Andrew, the flat roofs on later extensions tend to wear out long before the main roof.
Questions to ask before booking
- How long the report takes to arrive
- Whether the inside of the roof is included
- What the report includes, and whether it has photographs
- Which viewpoints they use to see the roof
Different roofs, different checks
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but punctures and seam failures still happen.
Liquid-applied waterproofing
Pinholes in a coating can let water through. Where the roof suits it, testing can find them.
Can I check my roof myself?
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
What affects the cost of electronic leak detection
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- Whether thermal imaging or a drone is needed
- How many separate roofs there are, such as extensions, dormers and garages
- The roof’s overall size
- Height and safe access
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Booking your survey
When you call or email, these details help:
- When you need the report by
- Where the property is, with the postcode
- Any photos you have, taken from ground level or a window
- What made you get in touch
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, call 07833 053749 or drop us an email.
Practical tips
From years of surveys, a few habits stand out:
- Record dates and spots where water appears
- Clear flat roof outlets regularly
- Make sure trades protect the waterproofing
- Check new waterproofing before handover
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
Common questions in Langenhoe
Is Langenhoe within the area you cover?
Yes, smaller places are covered as well as towns. We survey roofs across London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Is the coastal weather around Langenhoe hard on roofs?
Yes, coastal weather is harder on roofs: there is more wind, and more salt in the air. Ridges, verges, flashings and fixings are where it normally shows, and Langenhoe is within about 2 miles of the coast.
Can you survey a shared roof?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from whoever owns or manages the building. We inspect only the parts we are allowed to reach.
Is this a RICS survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you when booking.
Is the repair part of the test?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
Are you insured?
We hold professional indemnity and public liability insurance, for every survey we carry out.
