Electronic Leak Detection in Haultwick
Electronic leak detection to pinpoint holes in flat roof membranes for Haultwick, from an experienced roof surveyor. You get a clear written report with photographs.
- Repairs that haven’t stopped the leak
- Leaks through a covered membrane
- Breaches around outlets and penetrations
Common roof problems in Haultwick
Joints and laps in a membrane can fail over time. Small openings at laps can leak long before anyone notices.
Signs worth acting on include:
- Stains far from any visible defect
- Waterproofing to test before it’s covered
- A flat roof leak that cannot be traced
- Patched roofs that still leak
For site and facilities teams at buildings such as Munden Church of England Voluntary Controlled Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before you book any roof surveyor
- Is there a chance to talk the report through?
- Do they have a CAA Flyer ID and Operator ID for drone work?
- What the survey won’t cover
- How they plan to inspect the roof safely
Electronic leak detection in Haultwick
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or check a new membrane before handover. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends when conditions allow. Tell us about your roof to find out more. We survey green roofs, commercial flat roofs and liquid-applied waterproofing, and common reasons people get in touch are leaking laps in the waterproofing and water coming in under a flat roof.
Older buildings in small places like Haultwick may be listed or in a conservation area, which can shape what a new flat roof may look like. 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. Listed building consent is needed for changes that affect a listed building’s special interest.
Findings are set out part by part, from the main slopes down to the gutters and outlets, each with a short note and a photograph. It records what’s sound as well as what is not.

What electronic leak detection looks like in Haultwick
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. The wider area around Haultwick has a long history of building, with Aston Bury about 3.9 miles west. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
Take an older house close to Parish Church of All Saints: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. Landlords with a home close to Watton-At-Stone station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

The survey, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. You’re welcome to ask questions while we are there. Older rural homes like those around Haultwick can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before the survey
- Let us know about any leaks, stains or damp patches you know of
- Gather any invoices or paperwork from past roof work
- Unlock side gates and any roof access doors
How to book
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 use the contact form whenever suits you.
Advice
Tips that help
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Consider ELD before paving or planting goes on
- Find the breach before more patching
- Do not leave water getting in
- Tell us about the membrane and build-up if you know it
If anything in the report is not clear, ask us. We can talk you through the findings.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
Your questions about electronic leak detection in Haultwick
Does a conservation area affect roof work in Haultwick?
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. 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.
Is Haultwick in the area you cover?
Yes, Haultwick is within the area we cover. We work right across London and the South East. Just ring 07833 053749 or send us an email and let us know about the property.
What’s in the report?
It works through the roof part by part, in writing and with photos, finishing with recommendations. The most urgent items are made clear.
Is my roof suitable for ELD?
ELD does not suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. We’ll tell you if yours isn’t suitable at the start.
How long does electronic leak detection take?
It normally takes longer on a large roof than a small one, with the construction of the roof playing a part too.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are frequently shared, so we need permission from the building owner or managing agent. We inspect only the parts we are allowed to reach.
How experienced are you?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.

What affects the cost of electronic leak detection
A few things affect what a survey costs:
- Roof area
- The type of building, from a house to a block or an office
- How many separate roofs there are, like extensions, dormers and garages
- How complicated the roof is, with its valleys, chimneys and parapets
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You’ll know the price for your survey before booking.
Getting in touch
You don’t need to know any roofing terms. It’s enough to let us know:
- What’s prompted the survey
- Your timetable, such as an exchange date
- Where water is showing inside, if it is
- Anything about access we should know
To book a survey, phone 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.
Why get it checked now?
Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. Older and listed buildings around Haultwick may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
To find out what your survey will cost, ring 07833 053749 or drop us an email with the address and a few details. The price is agreed before a date is set.
