Graffham Electronic Leak Detection
We carry out electronic leak detection in Graffham and the rest of West Sussex. Surveys run on weekdays, Saturdays and Sundays.
- Repairs that haven’t stopped the leak
- Leaks showing away from the breach
- Leaks through a flat roof with no obvious cause
Can I check my roof myself?
What you cannot do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That’s where a survey comes in, using safe viewpoints and a drone where applicable.
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.
Electronic leak detection for homes and businesses in Graffham
Water can travel under a flat roof membrane before it shows inside. That makes leaks hard to trace by eye. ELD tests the waterproofing directly and locates the breach. It’s testing only, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. If you’re worried about gaps at membrane joints and waterproofing to test before it’s covered, we can find out what’s behind it, whatever the roof.
Somewhere as small as Graffham, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
The report does not just list problems. It explains what we found, why it matters and what we recommend.

Flat and commercial roofs around Graffham
Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. A few old Sussex buildings still carry heavy Horsham stone slabs. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. With Cowdray House about 3.5 miles north-west, Graffham sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
The streets around a church such as The Parish Church of St Giles are often among the oldest in a place, and if your house is among the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Graffham is about 9 miles north-east of Chichester, in West Sussex. We visit Graffham as part of our work across West Sussex, for houses, flats and commercial buildings. Graffham is one of the towns and villages in West Sussex we cover. You can also see our page for Portsmouth.

What electronic leak detection does not cover
A survey is a careful look at the flat roof membrane, but it cannot do everything. Its limits include:
- Build-ups without a suitable layer below
- Sections we can’t safely access
- Fixing the holes we find
If in doubt, phone 07833 053749 or email us and we’ll suggest the right survey. What our survey covers.
Roofs we survey in Graffham
- Liquid-applied waterproofing
- Single-ply roofs
- Commercial flat roofs
- Flat roof membranes
- Roof terraces and balconies
- Green roofs
Common roof problems in Graffham
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs though it depends on the layers.
Problems we come across frequently include:
- Holes around roof penetrations
- Patched roofs that still leak
- Leaking laps in the waterproofing
- Punctures from foot traffic or tools
For site and facilities teams at buildings such as Graffham CofE Infant School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Choosing a roof surveyor
- Which limits apply to the survey
- Their track record with similar roofs
- What insurance they carry
- How they’ll see the roof: from ground level, the loft, the roof or by drone

Surveys for landlords and agents in Graffham
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you get in touch and we will plan the visit with that in mind.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
Before and after the survey
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Ask contractors to protect the membrane
- Find the breach before more patching
- Don’t leave water getting in
- Have roof specifications to hand
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.
Common questions in Graffham
Is Graffham within the area you cover?
Yes, smaller places are covered as well as towns. Our area covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Graffham in the area you cover?
Yes, Graffham is within the area we cover. We cover the whole of London and South East England. You can phone 07833 053749 or email us with the address and a few details, and we will talk through which survey suits.
How is ELD priced?
We quote for each roof individually. Let us know about the roof and where it leaks, and call 07833 053749 or send us an email for a quote.
Does the weather affect the survey?
Light rain does not normally stop a survey, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we will agree a new date if the weather isn’t suitable.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage methods are usually carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
When does the report arrive?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
How many surveys have you done?
Over 20 years and more than 5,000 surveys, across London and South East England.
What we do, step by step
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. Cottages and farmhouses around Graffham often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely, and anything we cannot see is noted.
- 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.
Preparing for the visit
- Point out any leaks or damp patches
- If it is not your property yet, arrange access through the agent
- Let us know where we can park nearby
