Electronic leak detection in High Cross, West Sussex
Electronic leak detection to pinpoint holes in flat roof membranes for High Cross, from an experienced roof surveyor. Every survey comes with a written report and photos.

- Gaps at membrane joints
- Holes left by work on the roof
What electronic leak detection doesn’t cover
No survey can tell you everything, and we’d rather be clear about that before you book. Keep these in mind:
- Water entering through details rather than the membrane
- Sections we cannot safely access
- Repairing the breaches (that’s for your roofer)
If in doubt, call 07833 053749 or drop us an email and we will point you to the right survey. The full list of what we check.
Roof types and parts we check

- Liquid-applied waterproofing
- Flat roof membranes
- Single-ply roofs
- Green roofs
- Roof terraces and balconies
Electronic leak detection in High Cross: what you get
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help because they show what’s under the surface. We will tell you if the roof can’t be tested. Typical surveys look at leaks that return after repairs and water coming in under a flat roof, on green roofs, single-ply roofs and liquid-applied waterproofing.
Some older homes in villages like High Cross are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
Findings are set out part by part, from the main slopes down to the gutters and outlets, with a note and a photo for each point. You’ll see the good as well as the bad.

For landlords and managing agents
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Let us know about it as you book and we’ll plan the survey around it.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
What happens if roof problems are left?
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. In a place like High Cross, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
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 price for the job before booking.
Why book with us
- Thermal imaging and drones used where they help
- Plain-English reports with photos
- An independent view of the roof
- More than 5,000 surveys completed

What electronic leak detection looks like in High Cross
Older houses across Sussex frequently have handmade clay tiles, and many have tile-hanging on their upper walls. Some old buildings in 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. An older home may be listed, or stand in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent.
For landlords with property near Hassocks station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. The streets around a church such as The Parish Church of St Bartholomew are often among the oldest in a place, and if your home is one of the older ones nearby, flat-roofed rear additions and dormers added over the years are worth checking. Take a building like Albourne CofE Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Questions from High Cross
Is High Cross within the area you cover?
Yes, High Cross is covered. We work right across London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is High Cross in the area you cover?
Yes, High Cross is one of the places we work. The survey and report are the same in High Cross as anywhere else.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are often shared, so whoever owns or manages the building needs to agree access. We can only inspect what we’re given access to.
Do I need to be at home?
That depends on the survey. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when you book.
What’s the price of ELD?
We quote for each roof individually. Tell us about the roof and where it leaks. Just phone 07833 053749 or drop us an email for a quote.
Which method do you use?
We choose the method that suits the roof. We’ll explain why when we quote.
Does the weather affect the survey?
Light rain is normally fine; heavy rain and wind are different. Strong wind or a downpour can make access unsafe and ground a drone, so we’d move the date with you.
How the survey changes by roof type
Single-ply membranes
Some single-ply membranes suit electronic testing well, depending on the type and build-up.
Green and ballasted roofs
Some layers may need lifting for testing. We explain what’s needed when we quote.
What you can safely check yourself
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.

How the survey works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from each safe vantage point, photograph what we find and record our findings for the written report. Most visits take as long as needed for the roof’s area and construction, which we set out in the quote. In a hamlet or village like High Cross, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
How to prepare
- Have any questions written down, so nothing gets missed
- Dig out any old roof reports or invoices
- Keep pets in another room
