Electronic leak detection in Sandford-on-Thames: what you get
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. It will not show water getting in through brickwork or around frames. Our report keeps that distinction clear. We’ll point you to the likely next step. We survey roof terraces and balconies, commercial flat roofs and flat roof membranes, and common reasons people get in touch are a flat roof leak that can’t be traced and damage from equipment installers.
Older buildings in small places like Sandford-on-Thames may be listed or in a conservation area, which can shape what a new flat roof may look like. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
Every survey ends with a written report, with photographs, emailed to you. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Tips that help
A few practical points come up again and again on our surveys. They apply to most roofs:
- Limit access to the roof
- Have roof specifications to hand
- Record dates and spots where water appears
- Ask contractors to protect the membrane
If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer, and moisture readings can help.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
How it works
There is not much for you to do on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. A typical survey takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. For a village or hamlet like Sandford-on-Thames, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- First, you tell us about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photographs in a report for your roofer.
Preparing for the visit
- Tell us about parking before the day
- Keep pets inside or away from the areas we’re looking at
- Have any paperwork from past roof work to hand

Landlords, agents and block managers in Sandford-on-Thames
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
An agent can book and manage the survey for a landlord, and the report can go to both. We agree a time with the tenant beforehand.
Honest limits
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Moisture spread under the membrane
- Repairing the breaches (that’s for your roofer)
- Some conductive membranes

- Leaks that return after repairs
- Leaks through a flat roof with no obvious cause
- Breaches around outlets and penetrations
- Holes left by work on the roof
If you let a flat or house near Radley station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

FAQs for Sandford-on-Thames
Do you cover smaller places like Sandford-on-Thames?
We do. A small place gets exactly the same survey as a big one.
How do I find out if my home in Sandford-on-Thames is listed?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
How does ELD work?
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.
How soon will I get the report?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
How much does electronic leak detection cost?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. To get a quote, phone 07833 053749 or email us.
Do you climb onto every roof?
Only if it’s safe. We inspect what can be seen safely: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
What does the report include?
It sets out what we found, why it matters and what we recommend, backed by photos. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
