Electronic leak detection in Rudgwick, West Sussex
Not sure what state the flat roof membrane is in? We carry out electronic leak detection in Rudgwick and across West Sussex, with plain-English findings.
- New membranes needing a check before handover
- Damage from equipment installers
- Failed seams and laps
Roof by roof
Inverted and paved roofs
Paving and terraces cover the membrane. Suitability depends on the layers.
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
How electronic leak detection works in Rudgwick
ELD can be carried out in more than one way. Low-voltage testing is normally done with the surface wet, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof, and we’ll explain our choice. If neither method suits your roof, we’ll tell you at the outset. We survey roof terraces and balconies, commercial flat roofs and liquid-applied waterproofing, and people most often book us about leaks through a flat roof with no obvious cause and leaks that return after repairs.
In a small place like Rudgwick, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, normally show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
Nothing in the report is left vague: where something needs attention, it says so plainly.

Flat roofs in Rudgwick
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. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. What can be done to an older roof may depend on listing or a conservation area. The council is the place to check, along with Historic England’s list, ideally before any re-roofing is planned.
If you live in an older home near Holy Trinity Church, flat-roofed rear additions and dormers added over the years are worth checking. Landlords with a home close to Christs Hospital station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.

What happens on the day
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. Around Rudgwick, older homes can have small or awkward roof spaces, so it’s useful to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before we arrive
- Note where any stains or damp appear
- If you are buying, let the agent know when we are coming
- Make sure the loft hatch can be reached
Getting a price
If you have photos of the roof, send them over. Take them safely from the ground or a window, and please do not climb up for a closer look. To get started, phone 07833 053749 or drop us an email.

What a survey costs
Several things affect the price of a survey:
- The shape of the roof and its details
- Extensions, dormers and garages with roofs of their own
- The type of building, from a house to a block or an office
- The size of the roof
For a price for your roof in Rudgwick, ring 07833 053749 or email us and let us know about the roof. The price is agreed before a date is set.
Booking your survey
Getting the details right at the start saves time. Please include:
- Where water is showing inside, if it is
- Pictures of the roof from a safe spot, if you have them
- Anything about access we should know
- The reason for the survey, such as buying, a leak or storm damage
We confirm the price for your survey before booking, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, phone 07833 053749 or email us.
Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Consider ELD before paving or planting goes on
- Use boards when working on the roof
- Note where leaks show inside and when
- Do not leave water getting in
If water has been getting in, insulation under the membrane may be wet. That’s something to discuss with your roofer, and moisture readings can help.
Don’t leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
Common questions in Rudgwick
Is my home in Rudgwick listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Do you cover smaller places like Rudgwick?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Let us know about the roof and where it leaks, and call 07833 053749 or drop us an email for a quote.
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.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That’s how we locate breaches you cannot see.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you when booking.
Do you take photos of the roof?
Yes. The report includes photos of what we found, so you can see exactly what each finding refers to.
When to book a survey in Rudgwick
Roofs covered with paving, ballast or planting hide the membrane. Electronic methods can help on some of these roofs though it depends on the layers.
People normally book a survey after spotting one of these:
- Water coming in under a flat roof
- Patched roofs that still leak
- Damage from equipment installers
- Leaks under green or ballasted roofs
If you look after a building such as Rudgwick Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Choosing a roof surveyor
- Whether the loft is part of the inspection
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Which limits apply to the survey
- Are they insured for the work?
