Electronic Leak Detection in Crockenhill

How electronic leak detection works in Crockenhill
Electronic testing locates holes in the waterproofing but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. If the evidence points elsewhere, we will say so. It won’t show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. You’ll also know what to check next. We survey liquid-applied waterproofing, commercial flat roofs and single-ply roofs, and common reasons people get in touch are leaks through a flat roof with no obvious cause and damage from equipment installers.
In a small place like Crockenhill, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. 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 typically the first part of a flat roof to go.
Where we cannot see part of the flat roof membrane, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

How the survey changes by roof type
Liquid-applied waterproofing
Liquid waterproofing has no laps but holes and thin areas can occur. Suitability for ELD depends on the system.
Green and ballasted roofs
Parts of the covering may have to come up. We explain what’s needed when we quote.
The survey, step by step
It’s useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. Most visits take a length of time set by the membrane area and the build-up, which we set out in the quote. In a small place like Crockenhill, access is usually the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- 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.
Getting ready for the survey
- Make sure pets are kept safely away
- Let us know about parking near the property
- Agree roof access with the managing agent if it is shared

Advice
Questions from Crockenhill
Will you come out to Crockenhill?
Yes, Crockenhill is on our map. A small place gets exactly the same survey as a big one.
Is my home in Crockenhill listed or in a conservation area?
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.
How long have you been surveying roofs?
Over 5,000 surveys so far, across 20+ years of surveying roofs, and 98% of clients are satisfied.
Will you go up on the roof?
Only where it’s safe to do so. We inspect everything that’s safely in view: from the ground, from windows, from inside the roof space, from the roof where it is safe and by drone where applicable. Anything we can’t see is noted in the report.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Can you survey in bad weather?
Light rain does not usually stop a survey, and it can even help show where water is getting in. Strong wind or a downpour can stop drone flights and make roof access unsafe, so if conditions are not right we will arrange another day with you.
Do you look in the loft space?
Yes, where the survey calls for it and there’s safe access. We look for staining, damp, daylight and signs of movement.
What electronic leak detection looks like in Crockenhill
Across Kent, older roofs are often handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. You’ll also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. The wider area around Crockenhill has a long history of building, with Lullingstone Castle about 2.3 miles south-east. 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.
For an older house near a landmark such as Church of All Souls, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. For site and facilities teams at buildings such as Crockenhill Primary School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

Why act early in Crockenhill
Not every leak is in the membrane. Testing shows whether the membrane is breached so attention can go to the right place. Around Crockenhill, older homes often have old roof timbers, where water from a failed roof can cause rot if it’s left.

DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
