About our electronic leak detection in John's Cross
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 will discuss it with you when we quote. Any details of the build-up help because they show what’s under the surface. If testing isn’t possible, we’ll say so. If you’ve noticed stains far from any visible defect and leaks through a flat roof with no obvious cause, we can find out what’s behind it, whatever the roof.
In a village or hamlet like John's Cross, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
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.

FAQs for John's Cross
Do you cover John's Cross?
Yes, John's Cross is one of the places we work. Every survey there gets the same written report with photographs.
How do I find out if my home in John's Cross is listed?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you look in the roof space?
If there is a loft and safe access to it, yes. From inside, the underside of the roof often shows damp, staining or daylight that can’t be seen from outside.
How fast do I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed, ready to forward.
How long does electronic leak detection take?
Testing typically takes longer on a large roof than a small one, with the construction of the roof playing a part too.
What happens after the survey?
You will receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Can you test a green or ballasted roof?
On some roofs, yes. Covered roofs limit the methods we can use so we check the roof first.

Green and ballasted roofs
Parts of the covering may have to come up. We discuss this before quoting.
Bituminous membranes
Many flat roofs use bitumen-based membranes. The build-up decides which method will work.
When you need someone else
No survey can tell you everything, and it’s better to know them up front. Bear these in mind:
- The extent of water in the insulation
- Repairing the breaches (that’s for your roofer)
- Areas we can’t reach or that can’t be tested

What we do, step by step
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from every safe viewpoint, photograph what we find and record our findings for the written report. It normally takes a time that depends on the roof’s area and construction, which we set out in the quote. Cottages and farmhouses around John's Cross often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we can’t see is noted.
- 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.
Getting ready for the survey
- Agree roof access with the managing agent if it is shared
- Move anything stored under the loft hatch
- If you are buying, check with the agent that we can get in

We confirm the exact price before you book, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, ring 07833 053749 or drop us an email.
Advice
Prices for electronic leak detection in John's Cross
Prices vary from roof to roof, and it comes down to:
- The shape of the roof and its details
- Building height and the viewpoints available
- Extensions, dormers and garages with roofs of their own
- The type of building, from a house to a block or an office
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.
What we need to know
When you call or email, these details help:
- Any photos you have, taken from the ground or a window
- Whether there is a loft hatch, a shared roof or tricky access
- Any stains, drips or damp patches you’ve seen indoors

If you have photos of the roof, send them over. Take them safely from ground level or a window. To send them or to book, phone 07833 053749 or email us.

DIY checks: what’s safe
The one thing to avoid is getting up close. Roofs are fragile and slippery. That’s where a survey comes in, using safe viewpoints and a drone where applicable.
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
Flat roofs in John's Cross
Historic houses like Durhamford Manor, about 2.1 miles south-east, show how far back building in the area around John's Cross goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. Many older homes in Sussex have handmade clay tiles and tile-hung walls. Some old buildings in Sussex have Horsham stone slab roofs, and oast houses and timber-framed Wealden hall houses are part of East Sussex’s older buildings. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Take an older house close to The Parish Church of All Saints: the flat roofs on later extensions tend to wear out long before the main roof. Anyone responsible for a site like Vinehall School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you let a flat or house near Robertsbridge station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
