Electronic Leak Detection in Walton-on-Thames
Not sure what state the flat roof membrane is in? You can book electronic leak detection in Walton-on-Thames and across Surrey.
- Leaks through a covered membrane
- Water coming in under a flat roof
- Holes around roof penetrations
Should I look at the roof myself first?
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we check the roof.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Electronic leak detection in Walton-on-Thames
Some flat roofs can’t be tested electronically. Some membranes conduct electricity themselves and some roofs do not have a suitable layer beneath the membrane. If your roof is not suitable, we’ll tell you before any testing. Any details you have about the membrane and build-up help us decide, such as drawings or specifications. It saves a wasted visit. We survey flat roof membranes, roof terraces and balconies and green roofs, and common reasons people get in touch are leaks showing away from the breach and leaks through a covered membrane.
In a town like Walton-on-Thames, flat roofs are common on rear extensions, garages, porches and dormers. Many are felt, and newer ones may be EPDM rubber or GRP. Ponding water, splits along the edges and lifting upstands are the usual warning signs. Water that sits for days after rain is frequently the first sign a flat roof needs attention.
The report records the flat roof membrane as we found it on the day. It’s useful straight away, and a good reference for later, for instance when you want to check whether anything has changed.

Tips that help
There’s plenty you can do without going near the roof. What helps most:
- Avoid repeated repairs without finding the cause
- Stay off the flat roof unless needed
- Clear flat roof outlets regularly
- Act on new leaks promptly
Wet insulation may need attention after a leak. Your roofer can advise on that and other checks can help judge it.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
What we do, step by step
There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. A typical survey takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. For a home in Walton-on-Thames, the main things we need are a way into the loft, a route to the back garden and somewhere to park. If you will not be there yourself, let us know who will let us in.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Make a note of anything you’d like us to look at
- Dig out any old roof reports or invoices
- Leave side gates unlocked

Advice
Different roofs, different checks
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
For landlords and managing agents
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Tell us about it when you book and we will plan the survey around it.

Flat and commercial roofs around Walton-on-Thames
In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. With The Homewood about 2.5 miles south, Walton-on-Thames 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 any change of roofing material on a listed home needs checking with the council first.
Take an older house close to St John: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. For site and facilities teams at buildings such as Walton Oak Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. If you own a rental within reach of Walton-On-Thames station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

FAQs for Walton-on-Thames
Is there anything to prepare before you come to Walton-on-Thames?
The main thing is access, inside and out, plus somewhere to park in Walton-on-Thames. It also helps to know about any leaks or earlier repairs.
Is Walton-on-Thames in the area you cover?
Yes, Walton-on-Thames is one of the places we work. The survey and report are the same in Walton-on-Thames as anywhere else, and visits run on weekdays and weekends.
Do you test for asbestos?
No. We do not sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
Can every flat roof be tested?
It depends on the membrane and the build-up. Let us know what you know about the roof and we’ll check whether ELD will work.
How much time does ELD need?
It depends on the size of the roof and its build-up. You’ll know roughly how long before we start.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We look at the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
What does the report include?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
