Electronic leak detection in Cootham
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing will not show on the test. We will tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. You’ll also know what to check next. If you are worried about gaps at membrane joints and leaks through a covered membrane, we can find out what’s behind it, on commercial flat roofs, flat roof membranes and green roofs alike.
Some older homes in villages like Cootham 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. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later.

Questions from Cootham
Do you cover smaller places like Cootham?
Yes. Cootham is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and the South East. Just mention lanes, gates or anything else about the route when booking.
How do I find out if my home in Cootham is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photographs. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Will you walk on the roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs can’t always be walked on. Safe viewpoints, the loft and a drone where applicable let us see the rest.
Which method do you use?
The method is chosen to suit the roof. Low-voltage methods are normally carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
What’s the price of ELD?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. For a quote, phone 07833 053749 or drop us an email.
What do I do with the report?
You will receive the report 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.
What we look for on each type of roof
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
What we can’t see
Some things can’t be seen without opening up the roof, and that sets some limits:
- Sections we cannot safely access
- Leaks from walls, copings or rooflights
- Repairing the breaches (that’s for your roofer)
If you’re not sure which survey you need, ring 07833 053749 or email us and we’ll give you a straight answer before booking. What our survey covers.
What this survey covers

- Green roofs
Practical tips
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Get leaks traced quickly
- Tell us about the membrane and build-up if you know it
- Check trades protect the waterproofing
- Do not keep patching the same spot
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
What we do, step by step
After the inspection, everything we found is written up in a report with photos, emailed to you. As for time on site, most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. Cottages and farmhouses around Cootham often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- 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.
How to prepare
- Clear the way to the loft hatch
- For a flat or shared roof, check access with the freeholder or managing agent
- Have any paperwork from past roof work to hand
Book a survey
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or drop us an email when you are ready.
Related advice
What happens if roof problems are left?
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. Matching old materials, such as handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.
What you get with us

Flat roofs in Cootham
Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. A few old Sussex buildings still carry heavy Horsham stone slabs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. Parham House, about 1.1 miles west, is one of the historic houses in the wider area around Cootham. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
Take a building like Storrington Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. Landlords with a home close to Pulborough station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

DIY checks: what’s safe
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.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book, as it helps us focus the survey.
