Electronic leak detection for homes and businesses in Cholsey
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use and parts may need to be lifted. We talk this through before we quote. Any details of the build-up help because they show what’s under the surface. If testing is not possible, we will say so. We are frequently asked to look into leaking laps in the waterproofing and leaks that return after repairs, on liquid-applied waterproofing, single-ply roofs and green roofs.
In a smaller place like Cholsey, some flat roofs sit in the open, where wind can catch loose edges and trims. Sun on a flat roof also ages felt and bitumen. The signs are splits, blisters and edges coming away. A flat roof that still holds water days after rain is also worth a closer look.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t.

What affects the price in Cholsey
A few things affect what a survey costs:
- Any need for thermal images or a drone flight
- Roof area
- Whether it’s a home or a commercial building
- The height of the building and how the roof can be seen safely
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
What we need to know
These details help when you get in touch:
- Any deadline, like an exchange date
- Pictures from the garden or a window, if you have them
- The style of property, from a terrace to a block
- The reason for the survey, such as buying, a leak or storm damage
Getting a price is simple: just call 07833 053749 or send us an email, tell us about the property and we’ll explain which survey suits. We confirm the price before anything is booked.
Cholsey: your questions answered
Do you cover Cholsey?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Will you come out to Cholsey?
Yes. Cholsey is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and South East England. Just mention lanes, gates or anything else about the route when you book.
Can you test a green or ballasted roof?
It can be possible, depending on the roof. Covered roofs limit the methods we can use, so we check the build-up first.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. Roofs over flats are frequently shared, so we need permission from the freeholder or managing agent. We can only inspect what we are given access to.
Can every flat roof be tested?
Not every roof is suitable. Some membranes conduct electricity, and some build-ups lack a suitable layer below. If your roof won’t work, we will say so at the start.
Does the report include photographs?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
How experienced are you?
Over 20 years and more than 5,000 surveys.

What we look for on each type of roof
EPDM rubber roofs
EPDM rubber roofs frequently last 30–50 years, but punctures and seam failures still happen.
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. ELD can help locate them on suitable roofs.
What electronic leak detection looks like in Cholsey
West Oxfordshire’s older buildings frequently carry Cotswold stone slates, and a few villages in the county keep their 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. With Brightwell Manor about 2.9 miles north, Cholsey sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
Take an older house close to Church of St Mary: the joins between later flat roofs and the old walls are where problems typically start. Anyone responsible for a site like Cholsey Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Landlords with a home close to Cholsey station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

How the survey works
On the day, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can be seen safely. Most surveys take more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a smaller place like Cholsey, parking is seldom the issue; lanes, gates and long drives are worth mentioning. On bungalows and lower roofs, much can be seen from the ground, with the loft showing the underside, while taller roofs may need other vantage points or the drone where applicable.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
How to prepare
- Have any questions written down, so nothing gets missed
- Let us know about any leaks, stains or damp patches you know of
- Leave side gates unlocked

Advice
Tips from our surveys
A little preparation and a few simple habits help. Some pointers:
- Test new membranes before covering them
- Ask contractors to protect the membrane
- Record dates and spots where water appears
- Find the breach before more patching
If anything in the report is not clear, ask us. We’ll explain what was found and what it means.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
What we can’t see
It helps to know what a survey won’t do before you book:
- Areas we can’t reach or that cannot be tested
- Build-ups without a suitable layer below
- Moisture spread under the membrane
