Electronic leak detection in Fisher, West Sussex
We take a careful look at the flat roof membrane at your property in Fisher, and put it all in a report with photos.
- Leaks at pipes, outlets or fixings
- Breaches hidden under paving or planting
- Leaking laps in the waterproofing
How electronic leak detection works in Fisher
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. We’ll say if ELD won’t work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. We survey liquid-applied waterproofing, commercial flat roofs and single-ply roofs, and people most often book us about patched roofs that still leak and gaps at membrane joints.
Flat roofs on exposed homes in small places like Fisher take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, frequently 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 typically the first part of a flat roof to go.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

What affects the cost of electronic leak detection
Not every roof costs the same to survey, for these reasons:
- Whether thermal imaging or a drone is needed
- How many separate roofs there are, like extensions, dormers and garages
- The roof’s overall size
- Whether it’s a home or a commercial building
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.
Getting in touch
A little information up front helps. It helps to include:
- What made you get in touch
- What kind of property and roof it is
- Pictures from the garden or a window, if you have them
- Where water is showing inside, if it is

FAQs for Fisher
Will you come out to Fisher?
Yes, Fisher is covered. We survey roofs across London and the South East, and smaller places are part of that. Longer journeys are simply planned beforehand.
Does being near the coast affect roofs in Fisher?
Frequently, yes. Within about 2 miles of the sea, as Fisher is, metal fixings wear faster and gales find any loose ridge or slate.
Does someone need to be in?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you’ll need a RICS survey as well.
Can every flat roof be tested?
Not every roof is suitable. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof won’t work, we will say so before testing.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Does ELD work under paving or planting?
On some roofs, yes. Covered roofs limit the methods we can use so we look at the roof first.
The survey, step by step
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. The inspection then takes as long as needed for the roof’s area and construction, and we’ll give you a guide when quoting. Cottages and farmhouses around Fisher frequently have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
How to prepare
- Mention any parking restrictions on your street
- Leave a clear route to the loft
- If you are buying, let the agent know when we’re coming

Advice
Why it is worth a survey now in Fisher
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. Older and listed buildings around Fisher may need consent and matching materials for repairs, so leaving a defect until it’s urgent leaves less time to plan.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your survey before booking.

Do you need electronic leak detection in Fisher?
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Signs worth acting on include:
- Leaks at pipes, outlets or fixings
- Breaches hidden under paving or planting
- Water coming in under a flat roof
- Patched roofs that still leak
If you look after a building such as Chichester High School For Girls, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

What electronic leak detection looks like in Fisher
Fisher lies within about 2 miles of the sea, and being near the sea means more wind and salt than a roof inland would face. Coastal wind works at the edges of flat roofs, and salt air wears metal trims and fixings. If your home is older, it is worth knowing whether it is listed or in a conservation area before planning roof work. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area.
For landlords with property near Chichester station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. The streets around a church such as St Leodegar's Church are frequently among the oldest in a place, and if yours is one of the older homes 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.

- Liquid-applied waterproofing
- Flat roof membranes
- Single-ply roofs
- Green roofs
- Commercial flat roofs
- Roof terraces and balconies
What you can safely check yourself
A DIY look is useful, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in, using safe viewpoints and a drone where it applies.
