How electronic leak detection works in Tongham
Our ELD testing covers flat roofs in Tongham and the rest of London and the South East. A visit normally takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. Electronic leak detection is quoted for your roof, because the method depends on the roof. You get a written report with photos. If you’re worried about leaks that return after repairs and water coming in under a flat roof, we can find out what’s behind it, whatever the roof.
In smaller places like Tongham, 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. Knowing the covering and how it was laid tells you what to expect from it, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
Nothing in the report is left vague: if work is needed, the report says so clearly.

What we do, step by step
The visit usually starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. For a survey in Tongham, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.
- First, you let us know about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- 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.
Preparing for the visit
- Check the loft hatch can be reached
- Show us where any leaks or stains appear
- Let us know about parking near the property
Getting a price

Advice
Roof by roof
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.
Bituminous membranes
Bitumen roofs can frequently be tested electronically, depending on what’s below.
Flat and commercial roofs around Tongham
Historic houses such as Wanborough Manor, about 3.1 miles east, show how far back building in the area around Tongham goes. 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. Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Anyone responsible for a site like St Paul's CofE Infant School & Nursery will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. Take an older house close to Church of St Paul: the joins between later flat roofs and the old walls are where problems typically start.

What else we do in Tongham
Common questions in Tongham
Will you come out to Tongham?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Tongham?
We do. Every survey there gets the same written report with photos.
Can you test a green or ballasted roof?
In some cases. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We will discuss it before we quote.
Will you photograph what you find?
Yes. Photos are part of every report.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. To get a quote, ring 07833 053749 or email us.
Can you survey at the weekend?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
Do you test for asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
What we’re asked to look at in Tongham
When the membrane is buried, holes cannot be seen at all. ELD can work on some covered roofs though it depends on the layers.
A survey makes sense if you’ve noticed:
- Holes left by work on the roof
- Leaks under green or ballasted roofs
- Holes around roof penetrations
- A flat roof leak that cannot be traced
Landlords with a home close to Ash station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Questions to ask before booking
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- What the survey won’t cover
- What exactly goes into their report
- What happens after the report arrives
Checking the roof from the ground
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Why it is worth a survey now in Tongham
Not every leak is in the membrane. ELD helps rule the membrane in or out, so other causes can be checked. Homes in smaller places like Tongham can face more weather, so a loose ridge or verge soon lets rain in. Wind gets under it and lifts more, and water follows.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
