How electronic leak detection works in Norton
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use and parts may need to be lifted. We’ll discuss it with you when we quote. Any details of the build-up help because they show what’s under the surface. If testing is not possible, we will say so. We survey commercial flat roofs, green roofs and liquid-applied waterproofing, and common reasons people get in touch are damp inside with no sign on the roof and a flat roof leak that can’t be traced.
In a small place like Norton, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, usually 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.
Nothing in the report is left vague: if work is needed, the report says so clearly.

Your questions about electronic leak detection in Norton
Does a conservation area affect roof work in Norton?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Is Norton within the area you cover?
Yes, Norton is covered. We survey roofs across London and the South East, and smaller places are part of that. Longer journeys are simply planned ahead of time.
Which method do you use?
It depends on the membrane and the build-up. Low-voltage testing usually needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Can you test a green or ballasted roof?
In some cases. The layers on top and the build-up below decide it, and some may need lifting. We’ll discuss it before we quote.
Does this replace a RICS home survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
How fast do I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. We check the parts we are given access to.
How it works
After the inspection, everything we found is written up in a report with photos, sent to you by email. As for time on site, most surveys take longer on a large roof than a small one, with the construction of the roof playing a part too. Somewhere as small as Norton, 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 confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- Let us know about parking near the property
- Note where any stains or damp appear
- Buyers: confirm access with the estate agent or seller

Advice
Roof by roof
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Suitability for ELD depends on the system.
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Prices for electronic leak detection in Norton
What a survey costs depends on the time and equipment it needs. That comes down to:
- If the survey needs thermal imaging or a drone
- Height and safe access
- How many separate roofs there are, such as extensions, dormers and garages
- Roof area
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
Getting in touch
If you can, have these to hand when you get in touch:
- Any stains, drips or damp patches you’ve seen indoors
- What kind of property and roof it is
- What’s prompted the survey
- Photos of the roof, taken safely from the ground or a window
If you’re buying, it is useful to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply call 07833 053749 or email us whenever suits you.
Flat and commercial roofs around Norton
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 3.4 miles north lies Hinxworth Place, a reminder of how long the area around Norton has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
For landlords with property near Baldock station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you live in an older home near Church of St Nicholas, the flat roofs on later extensions tend to wear out long before the main roof.

Why get it checked now?

Signs you need electronic leak detection in Norton
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
Problems we come across frequently include:
- Holes left by work on the roof
- Waterproofing to test before it is covered
- Leaks through a covered membrane
- Leaks at pipes, outlets or fixings
For site and facilities teams at buildings such as Norton St Nicholas CofE (VA) Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
