Electronic Leak Detection in Tinsley Green
Know where you stand with the flat roof membrane before you spend money on it. We carry out electronic leak detection in Tinsley Green, with photographs and a clear written report.
- Repairs that haven’t stopped the leak
- Water coming in under a flat roof
- Leaks under green or ballasted roofs
What this survey cannot tell you
Without opening up the roof, some things stay hidden, so a survey has limits:
- Some conductive membranes
- Leaks from plumbing or windows
- The extent of water in the insulation

Electronic leak detection in Tinsley Green: what you get
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. If the evidence points elsewhere, we’ll say so. It won’t show water getting in through brickwork or around frames. Our report keeps that distinction clear. You’ll also know what to check next. If you’re worried about holes around roof penetrations and water coming in under a flat roof, we can find out what’s behind it, on commercial flat roofs, flat roof membranes and liquid-applied waterproofing alike.
Flat roofs on exposed homes in small places like Tinsley Green 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. Rubber and GRP last longer, though trims and joints still need a look. 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.

Why get it checked now?
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. In a small place like Tinsley Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.
Why us?
- An independent look at the roof
- PI and public liability insurance
- Drones and thermal imaging where it applies
- Surveys seven days a week

Do you need electronic leak detection in Tinsley Green?
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs, depending on the build-up.
We’re often asked to look at:
- Water coming in under a flat roof
- New membranes needing a check before handover
- Leaking laps in the waterproofing
- Holes left by work on the roof
Landlords with a home close to Gatwick Airport station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.
Questions to ask before you book

Tinsley Green: your questions answered
Do you cover Tinsley Green?
We do. The survey and report are the same in Tinsley Green as anywhere else, and visits run on weekdays and weekends.
Is Tinsley Green within the area you cover?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
Will you check the loft?
Typically, if there is one and it can be reached safely. From inside, the underside of the roof frequently shows damp, staining or daylight that cannot be seen from outside.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Share any details you have and we will check whether ELD will work.
How much time does ELD need?
It depends on the size of the roof and its build-up. We’ll give you an idea when we quote.
How much does electronic leak detection cost?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. To get a quote, phone 07833 053749 or use the contact form.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning, with the building owner or managing agent. Tell us about it when you book and we will explain what’s needed.
Flat and commercial roofs around Tinsley Green
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. Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. A few old Sussex buildings still carry heavy Horsham stone slabs. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you run a business near County Mall, the flat roofs over shops and commercial units are worth checking before a leak, not after. Take an older house close to St Michael and All Angels Church: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

What you can safely check yourself
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we look at the roof.

Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
Single-ply membranes
Many offices and units have single-ply roofs. Seams and penetrations are typical breach points.
The survey, step by step
Photographs are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. Most surveys take a length of time set by the size of the roof and how it’s built, which we set out in the quote. Somewhere as small as Tinsley Green, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- 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.
- You receive the results to pass to your roofer.
Preparing for the visit
- Buyers: confirm access with the estate agent or seller
- Agree roof access with the managing agent if it is shared
- Note where any stains or damp appear
Booking a survey
A quick phone call is normally the easiest start: call 07833 053749 or send us an email and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.
