Electronic Leak Detection in Catslip
Electronic leak detection to pinpoint holes in flat roof membranes around Catslip, with findings in writing and pictures to back them up. Book a weekday or weekend visit.

Electronic leak detection in Catslip: what you get
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair instead of hunting for the leak. Repair costs aren’t part of the report, so your roofer prices the work. A retest after repairs can check the work, where the roof still suits the method. You get a report with photos. We survey commercial flat roofs, single-ply roofs and flat roof membranes, and the problems we are asked to look at most are damage from equipment installers and repairs that haven’t stopped the leak.
Somewhere as small as Catslip, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: outlets, upstands, edges and the covering itself. We simply plan the journey and access ahead of time. Garages and outbuildings are easy to forget, so mention any you want included when you book.
The report records the flat roof membrane as we found it on the day. It is useful straight away, and a good reference for later, such as when you want to compare after future work.

Checking the roof from ground level
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Why it is worth a survey now in Catslip
Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first so your roofer knows where to work. Outbuildings and barns around Catslip are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your survey before booking.

- Leaks from plumbing or windows
- Moisture spread under the membrane

Local flat roofs in Catslip
Older buildings in west Oxfordshire frequently have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 2.2 miles south-east lies Greys Court, a reminder of how long the area around Catslip has been built on. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
For site and facilities teams at buildings such as Nettlebed Community School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. Landlords with a home close to Henley-On-Thames station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. If your house is among the older ones in the streets near Church of St Bartholomew, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Catslip is about 7 miles north of Caversham, in Oxfordshire. We provide electronic leak detection for householders, landlords and businesses in Catslip and the surrounding area. Across Oxfordshire, we cover Catslip. There is also a page for Reading.

Tips from our surveys
There is plenty you can do without going near the roof. What helps most:
- Clear flat roof outlets regularly
- Tell us about the membrane and build-up if you know it
- Find the breach before more patching
- Consider ELD before paving or planting goes on
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
How the survey changes by roof type
Green and ballasted roofs
Parts of the covering may have to come up. We discuss this before quoting.
EPDM rubber roofs
EPDM rubber roofs often last 30–50 years, but punctures and seam failures still happen.

Catslip questions
How do I find out if my home in Catslip is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you cover smaller places like Catslip?
Yes. Catslip is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

How do I arrange electronic leak detection in Catslip?
Simply call 07833 053749 or use the contact form. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
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.
Is the repair part of the test?
No. We test the membrane and report. You get the breach locations with photos so your roofer can fix them.
Can every flat roof be tested?
That depends on the roof’s membrane and layers. Share any details you have and we will check whether ELD will work.
What happens on the day
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. Somewhere like Catslip needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there is safe access and from the roof where it is safe.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- 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 the survey
- Let us know about parking before the day
- Have keys ready for side gates, garages or roof access doors
- Have any paperwork from past roof work to hand
