Electronic leak detection in Ayot Green: what you get
Our ELD report shows where each breach was found with photos. Your roofer can then repair those points instead of hunting for the leak. We don’t estimate repair costs; that is for your roofer to price. A retest after repairs can check the work, where the roof still suits the method. You get a written report with photos. If you are worried about punctures from foot traffic or tools and repairs that haven’t stopped the leak, we can find out what’s behind it, on liquid-applied waterproofing, commercial flat roofs and single-ply roofs alike.
Flat roofs on exposed homes in small places like Ayot Green take more wind and rain, 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. On an exposed roof, the edges tend to go first.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

How the survey changes by roof type
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible, depending on the build-up.

Ayot Green questions
How do I find out if my home in Ayot Green is listed?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you cover Ayot Green?
Yes. We work right across London and South East England, and Ayot Green is part of that. Just phone 07833 053749 or use the contact form and tell us about the property, and we will talk through which survey suits.
Does someone need to be in?
Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
How experienced are you?
More than 5,000 surveys over 20+ years.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, so wherever there’s a hole, it passes through. That lets us find breaches that are too small to see.
Is this a RICS survey?
No. This is a survey of the roof only, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
Do you take photos of the roof?
Yes. Photographs are part of every report, so you can see each point for yourself.
How the survey works
Photographs are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. Most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. Somewhere as small as Ayot Green, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- For flats, make sure roof access has been agreed
- Let us know about parking near the property
- Have any questions written down, so nothing gets missed

Do you need electronic leak detection in Ayot Green?
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
Problems we come across often include:
- Leaks through a covered membrane
- Breaches around outlets and penetrations
- Punctures from foot traffic or tools
- A flat roof leak that can’t be traced
For an older house near a landmark such as Church of St Peter, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
Choosing a roof surveyor
- What follow-up you get after the report
- What exactly goes into their report
- How long the report takes to arrive
- How much experience they have with roofs like yours
What affects the price in Ayot Green
When we price a survey, we consider:
- The type of building, from a house to a block or an office
- The use of thermal imaging or a drone
- Extensions, dormers and garages with roofs of their own
- The roof’s overall size
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.
Booking your survey
A little information up front helps. It helps to include:
- The address and postcode of the property
- Where water is showing inside, if it is
- The style of property, from a terrace to a block
- Dates you’re working to, such as exchange
Booking is simple: just ring 07833 053749 or use the contact form, let us know about the property and we will point you to the right survey. We confirm the price before anything is booked.
Can I check my roof myself?
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book and it will help the survey.
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight.
What happens if roof problems are left?
Testing a new membrane before it’s covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. Matching old materials, such as handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
For a price for your roof in Ayot Green, call 07833 053749 or drop us an email and tell us about the roof. We’ll confirm the figure before booking.

Flat and commercial roofs around Ayot Green
About 1.1 miles east lies Digswell House, a reminder of how long the area around Ayot Green has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you own a rental within reach of Welwyn Garden City station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take a building like Monk's Walk School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
