How electronic leak detection works in Partridge Green
ELD finds breaches in the membrane but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. We will tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. Our report keeps that distinction clear. You will also know what to check next. Typical surveys look at patched roofs that still leak and water coming in under a flat roof, on roof terraces and balconies, single-ply roofs and liquid-applied waterproofing.
In a small place like Partridge Green, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which frequently last around 15–20 years, usually show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

What we’re asked to look at in Partridge Green
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak long before anyone notices.
These are some of the problems a survey can pick up:
- Leaks showing away from the breach
- Patched roofs that still leak
- Leaks at pipes, outlets or fixings
- New membranes needing a check before handover
Take a building like Jolesfield CofE Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Before you book any roof surveyor
- What the report includes, and whether it has photos
- Which viewpoints they use to see the roof
- How long they’ve been surveying roofs
- How soon the report will arrive
How it works
The visit has one job: to see as much of the flat roof membrane as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. It normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. Rural addresses near Partridge Green can be hard to find from a postcode alone, 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.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before we arrive
- For a flat or shared roof, check access with whoever owns or manages the building
- Dig out any old roof reports or invoices
- Keep pets in another room

Flat roofs in Partridge Green
Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Horsham stone slab roofs survive on some old Sussex buildings. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. England has around 10,000 conservation areas and about 500,000 listed buildings. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so check with the council.
The streets around a church like St Michael and All Angels Church are often among the oldest in a place, and if yours is one of the older homes nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

Honest limits
Some things cannot be seen without opening up the roof, and that sets some limits:
- The extent of water in the insulation
- Water entering through details rather than the membrane
- Carrying out the repair work
If you are not sure which survey you need, ring 07833 053749 or email us and we will give you a straight answer before booking. The full list of what we check.
What this survey covers
- Roof terraces and balconies
- Single-ply roofs
- Flat roof membranes
- Green roofs
- Liquid-applied waterproofing
- Commercial flat roofs
What you can safely check yourself
What you cannot do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That is where a survey comes in, using safe viewpoints and a drone where it applies.
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
Tips that help
There is plenty you can do without going near the roof. Here’s what helps most:
- Have roof specifications to hand
- Clear flat roof outlets regularly
- Check new waterproofing before handover
- Get leaks traced quickly
If anything in the report isn’t clear, ask us. We will explain what was found and what it means.
Check contractors protect the waterproofing when they work up there. Check the roof after they’ve finished.

Questions from Partridge Green
Is my home in Partridge Green listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Do you cover Partridge Green?
Yes, Partridge Green is one of the places we work. The survey and report are the same in Partridge Green as anywhere else.
How long does electronic leak detection take?
It normally takes a length of time set by the size of the roof and how it’s built, which we set out in the quote.
Can you inspect my roof with a drone?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
Do you carry professional indemnity insurance?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
Will you repair the leak?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
Do I need to be at home?
That depends on the survey. For inside areas and the roof space, someone has to give us access; we will agree the details as you book.
