Electronic leak detection in Fontwell: what you get
Our ELD testing covers flat roofs in Fontwell and the rest of London and South East England. Testing usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. Electronic leak detection is quoted for your roof, because the method depends on the roof. You get a report with photographs. We are often asked to look into holes around roof penetrations and patched roofs that still leak, across liquid-applied waterproofing, commercial flat roofs and green roofs.
Flat roofs on exposed homes in small places like Fontwell take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, often 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 normally the first part of a flat roof to go.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

Useful tips for Fontwell property owners
Some practical points come up on survey after survey. They apply to most roofs:
- Clear flat roof outlets regularly
- Don’t leave water getting in
- Don’t keep patching the same spot
- Stay off the flat roof unless needed
If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer, and moisture readings can help.
Act on leaks quickly. Water under a membrane can spread.
What happens on the day
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe vantage point, photograph what we find and record our findings for the written report. Most visits take longer on a large roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like Fontwell can have low, tight loft spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- 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 testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
How to prepare
- Check the loft hatch can be reached
- For a flat or shared roof, check access with whoever owns or manages the building
- Have any questions written down, so nothing gets missed

Fontwell: your questions answered
How do I find out if my home in Fontwell is listed?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Is the coastal weather around Fontwell hard on roofs?
Near the coast, roofs face more wind and more salt than further inland. Salt is hard on nails, clips and metal flashings, while strong wind lifts anything already loose.
What is electronic leak detection?
A sound membrane blocks the test current, but a hole lets it through. That lets us find breaches that are too small to see.
How much does electronic leak detection cost?
We quote for each roof individually. Send us details of the roof. Just call 07833 053749 or email us for a quote.
Do you climb onto every roof?
Only where it is safe to do so. We inspect everything that’s safely in view: from the ground, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. Anything we can’t see is noted in the report.
How do I book a survey in Fontwell?
It is easiest to ring 07833 053749 or drop us an email. Give us the address and some details about the roof, and we will point you to the right survey. Surveys run on weekdays, Saturdays and Sundays.
Are you insured?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
Flat roofs in Fontwell
Fontwell lies within about 5 miles of the sea, and places near the sea get more salt in the air and more wind than inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. With Goodwood House about 4.2 miles west, Fontwell sits in an area with a long building history. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof.
Take a building like Ormiston Six Villages Academy: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Do you need electronic leak detection in Fontwell?
Water travels under flat roof membranes. The leak may show some distance from where water gets in which makes it hard to find by looking.
Here are some of the things we see often:
- Leaks through a flat roof with no obvious cause
- Leaks that return after repairs
- Breaches around outlets and penetrations
- Damage from equipment installers
If you own a rental within reach of Barnham station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
What to check before booking
- Whether the loft is part of the inspection
- What follow-up you get after the report
- Their drone registration, if they fly one
- Whether VAT is added on top
When you need someone else
It is a careful look at the flat roof membrane, not the whole story. Its limits include:
- How wet the insulation is
