How electronic leak detection works in Compton
Some flat roofs cannot be tested electronically. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. If your roof is not suitable, we’ll tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It saves a wasted visit. Common reasons to book are a flat roof leak that can’t be traced and breaches hidden under paving or planting, across liquid-applied waterproofing, roof terraces and balconies and single-ply roofs.
Some older homes in villages like Compton 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.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Can I check my roof myself?
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
A DIY look is useful, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
The survey, step by step
The visit usually starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes longer on a large roof than a small one, with the construction of the roof playing a part too. Around Compton, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Let us know where we can park nearby
- If you are buying, let the agent know when we are coming
Booking a survey
If you have photos of the roof, send them over. Pictures from the ground or a window are fine, and please do not climb up for a closer look. To get started, call 07833 053749 or use the contact form.

Electronic leak detection in Compton: local notes
In Sussex, older roofs are frequently handmade clay tile, frequently with tile-hanging on the walls below. A few old Sussex buildings still carry heavy Horsham stone slabs. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. Uppark, about 1.8 miles north, is one of the historic houses in the wider area around Compton. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
If you own a rental within reach of Rowlands Castle station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Anyone responsible for a site like Compton and Up Marden CofE Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If your house is among the older ones in the streets near The Parish Church of St Mary, the joins between later flat roofs and the old walls are where problems typically start.
Compton is about 5 miles east of Horndean, in West Sussex. If you’re in Compton, booking works exactly as it does anywhere else: get in touch, agree the price and pick a day. Our area takes in places right across West Sussex, large and small. There’s also a page for Portsmouth.

Different roofs, different checks
EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We will say if the test won’t work.
Single-ply membranes
ELD often works on single-ply membranes but it depends on the product and layers.
What affects the price in Compton
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- Extensions, dormers and garages with roofs of their own
- If the survey needs thermal imaging or a drone
- Commercial roofs and larger buildings
- The shape of the roof and its details
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for the job before you book.
Getting in touch
A little information up front helps. It helps to include:
- The type of building and roof, such as pitched or flat
- Pictures from the garden or a window, if you have them
- Where any leaks, stains or damp patches show inside
- Where the property is, with the postcode
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply phone 07833 053749 or send us an email whenever suits you.
Questions from Compton
Is my home in Compton listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is Compton in the area you cover?
Yes, Compton is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Do I need to be at home?
Not always. If we only need the outside, we can agree that beforehand, but anything inside needs someone there to give access.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Will you walk on the roof?
Not always. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the loft space and a drone where it applies.
How experienced are you?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and the South East.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
Why act early in Compton
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. In a small place like Compton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
