About our electronic leak detection in Windmill Hill
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. You get a written report with photos of each breach found. Typical surveys look at leaks that return after repairs and water coming in under a flat roof, across single-ply roofs, green roofs and flat roof membranes.
In a small place like Windmill Hill, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, frequently around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
We keep jargon out of it: where something needs attention, it says so plainly.

Windmill Hill: your questions answered
Does a conservation area affect roof work in Windmill Hill?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Do you cover smaller places like Windmill Hill?
Yes. Windmill Hill is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and South East England. Let us know about access, parking and anything unusual about getting there when you book.
How long will testing take?
Testing usually takes a length of time set by the size of the roof and how it’s built, which we set out in the quote.
What do I do with the report?
We email you the written report with photographs and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Can you survey at the weekend?
Surveys run on any day of the week. To arrange a date, ring 07833 053749 or send us an email.
Does the weather affect the survey?
It depends on the weather and the survey. Strong wind or heavy rain can make access unsafe and ground a drone, and we’d agree another day.
Will you repair the leak?
No, our part is finding the breaches. The report gives your roofer the locations.
When you need someone else
We only report everything that’s safely in view on the day, so there are some things a survey cannot cover:
- Moisture spread under the membrane
- Leaks from plumbing or windows
- Areas we cannot reach or that can’t be tested
If you are not sure which survey you need, ring 07833 053749 or email us and we will give you a straight answer before you book. What our survey covers.
What this survey covers

Surveys for landlords and agents in Windmill Hill
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out in order of urgency where relevant.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
How we price electronic leak detection
Prices vary from roof to roof, and it comes down to:
- Extra roofs, like extensions, dormers or garages
- The height of the building and how the roof can safely be seen
- The size of the roof
- Whether thermal imaging or a drone is needed
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the price for the job before booking.
What we need to know
What helps most when you contact us:
- Where any leaks, stains or damp patches show inside
- Access details, such as a loft hatch or a shared roof
- Your postcode, so we can check access and travel
- Any deadline, such as an exchange date
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or drop us an email whenever suits you.

How the survey changes by roof type
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. The build-up decides which method will work.
What happens on the day
When we arrive, we start by asking what you’ve noticed and what you’d like to know. We then inspect everything that can safely be seen. Most surveys take a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. Older roofs in small places like Windmill Hill can have low, tight loft spaces, so tell us about the loft hatch and any ladder. We only go where it’s safe.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photographs in a report for your roofer.
Before the survey
- Let us know where we can park nearby
- Move anything stored under the loft hatch
- Check pets are kept safely away
Booking 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.

Why act early in Windmill Hill
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. Older and listed buildings around Windmill Hill may need consent and matching materials for repairs, so leaving a defect until it is urgent leaves less time to plan.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.

Flat roofs in Windmill Hill
Older buildings in Essex often have clay tiles and weatherboarding, while many towns grew with post-war and newer estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses like Layer Marney Tower, about 2.9 miles east, show how far back building in the area around Windmill Hill goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
Anyone responsible for a site like Baynards Primary School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. For an older house near a landmark like Parish Church of All Saints (inworth), the flat roofs on later extensions tend to wear out long before the main roof. If you let a flat or house near Kelvedon station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
