Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we’ll plan the visit with that in mind.
About our electronic leak detection in Henley-on-Thames
Electronic testing locates holes in the waterproofing but not every way water gets 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. The report makes clear what was and wasn’t tested. We’ll point you to the likely next step. We survey commercial flat roofs, liquid-applied waterproofing and green roofs, and people most frequently book us about waterproofing to test before it’s covered and repairs that haven’t stopped the leak.
In smaller places like Henley-on-Thames, flat roofs are mostly on extensions, garages, porches and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it’s covered in, and how well it was laid, decides what it needs. Ponding, splits and lifting edges are the signs to look for from a window.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

How we price electronic leak detection
Not every roof costs the same to survey, and it comes down to:
- The number of roofs, including extensions and garages
- Whether thermal imaging or a drone is needed
- House, block, shop or office
- How big the roof is
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your roof before booking.
Helping us price your survey
If you can, have these to hand when you get in touch:
- Whether there’s a loft hatch, a shared roof or tricky access
- Pictures of the roof from a safe spot, if you have them
- What kind of property and roof it is
- Your postcode, so we can check access and travel
Photos help, if you have them. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, call 07833 053749 or use the contact form.

Electronic leak detection in Henley-on-Thames: local notes
About 2.3 miles west lies Greys Court, a reminder of how long the area around Henley-on-Thames has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. There are several hotels within about a mile and a half of Henley-on-Thames. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
Take a building like Trinity Church of England Primary School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. Take an older house close to Holy Trinity Church: the flat roofs on later extensions tend to wear out long before the main roof.

Henley-on-Thames: your questions answered
Is Henley-on-Thames within the area you cover?
Yes, we do. We cover the whole of London and South East England, and smaller places are part of that. Longer journeys are simply planned beforehand.
Does a conservation area affect roof work in Henley-on-Thames?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach, and the report makes that clear.
What’s the best way to book?
Simply ring 07833 053749 or email us. After a few questions, we confirm the price and fix a day, weekday or weekend.
What is electronic leak detection?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That lets us find breaches that are too small to see.
What does the report include?
It sets out what we found, why it matters and what we recommend, backed by photos. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Do you carry out surveys on Saturdays and Sundays?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days when you book.
Why get it checked now?
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. Around Henley-on-Thames, leaves and moss in gutters lead to overflowing water and damp walls, especially where trees overhang. Dealing with the cause is simple; drying out a wall is not.
To find out what your survey will cost, call 07833 053749 or use the contact form and tell us about the roof. We’ll confirm the figure before booking.

What happens on the day
The visit normally starts outside and finishes in the loft: outside views come first, then the roof space if there’s safe access. All told, expect longer on a large roof than a small one, with the construction of the roof playing a part too. Parking around Henley-on-Thames is typically easier than in a town centre, but mention lanes, gates or long drives. On bungalows and lower roofs, much can be seen from ground level, with the loft showing the underside.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Getting ready for the survey
- Mention any parking restrictions on your street
- Show us where any leaks or stains appear
- Keep pets out of the way during the survey
