About our electronic leak detection in Warnham
We carry out electronic leak detection on flat roofs in Warnham and across London and the South East. Testing usually takes as long as needed for the membrane area and the build-up, which we’ll explain when we quote. Electronic leak detection is quoted for your roof, because the method depends on the roof. The results come in a written report with photos. We survey flat roof membranes, roof terraces and balconies and liquid-applied waterproofing, and common reasons people get in touch are damage from equipment installers and gaps at membrane joints.
Some older homes in villages like Warnham are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
Every survey ends with a written report, with photographs, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

FAQs for Warnham
Does a conservation area affect roof work in Warnham?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you cover Warnham?
Yes, Warnham is one of the places we work. The survey and report are the same in Warnham as anywhere else, and visits run on weekdays and weekends.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Let us know what you know about the roof and we will confirm suitability.
How does ELD work?
The waterproofing membrane normally stops an electrical current, so wherever there is a hole, it passes through. That is how we locate breaches you can’t see.
What happens next?
You will receive the report by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
How much time does ELD need?
Testing usually takes a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting.
How quickly is the report sent?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email, ready to forward.
Landlords, agents and block managers in Warnham
We survey roofs for landlords and letting agents as well as homeowners. A written report with photographs gives you a clear record of the flat roof membrane.
Letting agents can arrange access with tenants, at a time agreed ahead of time. Surveys run on any day of the week, which helps when tenants work during the week.

Common roof problems in Warnham
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole which makes it hard to find by looking.
A survey makes sense if you’ve noticed:
- Leaks through a flat roof with no obvious cause
- Leaks showing away from the breach
- Holes around roof penetrations
- Leaks that return after repairs
If you look after a building such as Warnham CofE Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Choosing a roof surveyor
- Which viewpoints they use to see the roof
- What experience they bring
- Their report turnaround times
- What follow-up you get after the report
Why get it checked now?
Repairs in the wrong place leave the leak in place. Testing shows where the membrane is actually breached. Older and listed buildings around Warnham may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

What we do, step by step
The aim of the visit is simple: to see as much of the flat roof membrane as can be seen safely and record it clearly. Notes and photos go into the written report. 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. Around Warnham, older homes can have small or awkward roof spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.

What electronic leak detection looks like in Warnham
Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Some old buildings in Sussex have Horsham stone slab roofs. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. 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 the council is the place to ask.
If you live in an older home near The Parish Church of St Margaret, the flat roofs on later extensions tend to wear out long before the main roof. Landlords with a home close to Warnham station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
