Electronic Leak Detection in Steyning
Electronic leak detection to pinpoint holes in flat roof membranes for Steyning and the rest of West Sussex. We survey on any day of the week.
- Failed seams and laps
- Damp inside with no sign on the roof
- Punctures from foot traffic or tools
What electronic leak detection doesn’t cover
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Moisture spread under the membrane
- Roofs whose membrane or build-up is not suitable
- Leaks from walls, copings or rooflights

Electronic leak detection for homes and businesses in Steyning
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly, to find where it has been breached. It’s testing only and leave the repair to 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. We survey liquid-applied waterproofing, green roofs and single-ply roofs, and common reasons people get in touch are new roofs to check before paving or planting and leaking laps in the waterproofing.
Around a smaller place like Steyning, flat roofs typically cover extensions, garages and dormers. Even a small flat roof can let lots of water into the room below. Knowing the covering and how it was laid tells you what to expect from it. From an upstairs window, look for standing water, splits and edges coming away.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later.

FAQs for Steyning
Is the coastal weather around Steyning hard on roofs?
Places near the sea get more wind and more salt in the air than inland, and both are hard on roofs. Salt corrodes metal fixings and flashings, and wind lifts loose slates, tiles and ridge pieces.
Can you look at the flat roof of a hotel or office near Steyning?
Yes. As well as homes, we look at flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you will get a quote based on the building, and roof access is agreed with you ahead of the visit.
Does this replace a RICS home survey?
No. We’re 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.
Is it a structural engineer’s report?
No. We note visible signs like sagging or deflection, but we’re not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.
What do I do with the report?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
How fast do I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email.
Do you work in Steyning?
Yes. We survey roofs across London and South East England, and that includes Steyning.
Tips that help
Most of what helps is simple and safe from the ground. A few suggestions:
- Avoid repeated repairs without finding the cause
- Keep a note of leaks after rain
- Share any drawings of the roof
- Stay off the flat roof unless needed
The report records each breach location with photos. Your roofer uses it to carry out repairs.
Ask trades working on the roof to protect the membrane when fitting equipment. Check the roof after they’ve finished.
What happens on the day
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. A visit to Steyning is planned like any other: the time, the access and where to park are agreed ahead of time. Weekday and weekend visits are both possible. Let us know about any garages, outbuildings or extensions you want included.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Preparing for the visit
- Leave side gates unlocked
- Buyers: confirm access with the estate agent or seller
- Make sure the loft hatch can be reached
How to book
If you are buying, it’s useful to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply call 07833 053749 or send us an email whenever suits you.

What we look for on each type of roof
Green and ballasted roofs
ELD is easier on a new roof before it is covered.
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Laps and fixings are where holes often appear.
Flat and commercial roofs around Steyning
Steyning lies within about 5 miles of the sea, where sea air brings more salt and stronger wind than inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. Steyning has a number of hotels within about a mile and a half, and hotels, like offices and blocks of flats, often have flat roofs. If you look after one, a leak through a flat roof can put a room out of use.
For landlords with property near Lancing station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you look after a building such as Steyning CofE Primary School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. Hotels and guest houses near Steyning can’t easily close rooms for a leak, so it pays to find faults before guests do.

How we price electronic leak detection
When we price a survey, we consider:
- Commercial roofs and larger buildings
- The size of the roof
- Whether thermal imaging or a drone is needed
- How tall the building is and how easy the roof is to see
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.
Helping us price your survey
The more you let us know, the easier it is to price the survey. When you contact us, it helps to mention:
- What’s prompted the survey
- The property’s address and postcode
- The kind of building and roof involved
- Any stains, drips or damp patches you’ve seen indoors
You can call us seven days a week. For a price or to book, ring 07833 053749 or email us.
What happens if roof problems are left?
Testing a new membrane before it is covered is easier than tracing a leak later. Covered roofs are harder to test. Tradespeople may need to travel further to a smaller place like Steyning, so it’s useful to plan roof work rather than call someone out in a hurry. Knowing early gives you time to get the right people in.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your roof before booking.
