Electronic leak detection for homes and businesses in West Grinstead
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. If the evidence points elsewhere, we’ll say so. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. We will point you to the likely next step. Typical surveys look at leaks under green or ballasted roofs and leaks at pipes, outlets or fixings, on green roofs, commercial flat roofs and liquid-applied waterproofing.
Older buildings in small places like West Grinstead may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
Nothing in the report is left vague: where something needs attention, it says so plainly.

Signs you need electronic leak detection in West Grinstead
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs, depending on the build-up.
Common reasons to book include:
- Leaks under green or ballasted roofs
- Stains far from any visible defect
- Holes left by work on the roof
- Leaks through a flat roof with no obvious cause
Whatever the street in West Grinstead, a roof costs least to look after when faults are caught early.
Choosing a roof surveyor
- Whether any drone flown is registered with the CAA
- What the survey won’t cover
- Will they check the loft as well as the outside?
- What exactly goes into their report
Tips that help
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Don’t keep patching the same spot
- Get leaks traced quickly
- Note where leaks show inside and when
- Don’t let outlets block
Keep the report with the roof’s records. It is a dated record of the membrane’s condition.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
What electronic leak detection looks like in West Grinstead
Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand, before anyone quotes for re-roofing. In Sussex, older roofs are frequently handmade clay tile, frequently with tile-hanging on the walls below. Horsham stone slab roofs survive on some old Sussex buildings. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Take an older house close to Shrine Church of Our Lady of Consolation and St Francis: the joins between later flat roofs and the old walls are where problems normally start.

How the survey works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes longer on a large roof than a small one, with the construction of the roof playing a part too. If you have questions on the day, just ask. Around West Grinstead, older homes can have small or awkward roof spaces, so it’s useful to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Preparing for the visit
- Jot down any questions you want answered
- Have keys ready for side gates, garages or roof access doors
- If it is not your property yet, arrange access through the agent

Related advice
Should I look at the roof myself first?
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.

Can you give me structural calculations?
No. We note visible signs such as sagging or deflection, but we are not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.
Do I need to be at home?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you when booking.
