Different roofs, different checks
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible, depending on the build-up.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Suitability for ELD depends on the system.
Electronic leak detection for homes and businesses in Crowhurst Lane End
Roofs covered with paving, ballast or planting need more thought. 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’ll say so. We survey green roofs, flat roof membranes and commercial flat roofs, and common reasons people get in touch are new membranes needing a check before handover and a flat roof leak that can’t be traced.
In a small place like Crowhurst Lane End, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, usually show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

Leave it or get it looked at?
Testing a new membrane before it is covered is easier than tracing a leak later. Covered roofs are harder to test. Matching old materials, such as handmade tiles or stone slates, can take time to source. That’s one more reason to find defects before they become urgent.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.

Tips that help
You do not need to be a roofer to help. What helps most:
- Stay off the flat roof unless needed
- Consider ELD before paving or planting goes on
- Keep a note of leaks after rain
- Get leaks traced quickly
If anything in the report is not clear, ask us. We’ll explain what was found and what it means.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
Crowhurst Lane End questions
Does a conservation area affect roof work in Crowhurst Lane End?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Do you cover Crowhurst Lane End?
Yes, Crowhurst Lane End is within the area we cover. We work right across London and South East England. Just ring 07833 053749 or use the contact form and tell us about the property.
How long have you been surveying roofs?
Over 5,000 surveys so far, over more than 20 years, and 98% of clients are satisfied.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Does ELD work under paving or planting?
On some roofs, yes. Covered roofs limit the methods we can use so we check the roof first.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. For a quote, call 07833 053749 or send us an email.
What happens next?
You’ll receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
What we cannot see
No survey can tell you everything, and we’d rather be clear about that before booking. Bear these in mind:
- Roofs whose membrane or build-up is not suitable
- How wet the insulation is
- Leaks from plumbing or windows
If in doubt, ring 07833 053749 or drop us an email and we’ll recommend the right survey. What our survey covers.

How we price electronic leak detection
When we price a survey, we consider:
- Roof area
- Whether it is a home or a commercial building
- Features like valleys, chimneys, dormers and parapets
- Extra roofs, like extensions, dormers or garages
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Electronic leak detection around Crowhurst Lane End
With Titsey Place about 4.6 miles north-east, Crowhurst Lane End sits in an area with a long building history. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For landlords with property near Godstone station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take a building like St Stephen's CofE Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you live in an older home near Church of St George, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

What we do, step by step
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself takes as long as needed for the membrane area and the build-up, which we set out in the quote. Around Crowhurst Lane End, older homes can have small or awkward roof spaces, so tell us about the loft hatch and any ladder. We only go where it is safe.
- 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.
- The method depends on the membrane and what sits above and below it.
- 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.
How to prepare
- Leave side gates unlocked
- Leave a clear route to the loft
- For flats, check roof access has been agreed
