Electronic leak detection in Leatherhead: local notes
Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Horsham stone slab roofs survive on some old buildings in Surrey. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. Polesden Lacey, about 3.4 miles south-west, is one of the historic houses in the wider area around Leatherhead. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
If you look after a shop, office or commercial unit, for example near The Ashley Centre, a flat roof over a business is out of sight and out of mind until it leaks. If you look after a building such as Leatherhead Trinity School and Children's Centre, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you own a rental within reach of Leatherhead station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Electronic leak detection in Leatherhead
Some flat roofs cannot be tested electronically. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. If your roof is not suitable, we’ll tell you at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. If you’ve noticed holes around roof penetrations and leaks showing away from the breach, we can find out what’s behind it, on liquid-applied waterproofing, roof terraces and balconies and single-ply roofs alike.
In a town like Leatherhead, 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 is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to, with the urgent items made clear.

Useful tips for Leatherhead property owners
Over many surveys, some simple habits stand out as worth the effort:
- Stay off the flat roof unless needed
- Have roof specifications to hand
- Clear flat roof outlets regularly
- Act on new leaks promptly
Wet insulation may need attention after a leak. That’s something to discuss with your roofer and other checks can help judge it.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Why it is worth a survey now in Leatherhead
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss, on suitable membranes. Around Leatherhead, gutters that overflow soak the wall below. At roof level, a loose tile or tired flashing does the same. Neither gets better on its own.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

For landlords and managing agents
Letting agents can arrange access with tenants, at a time agreed ahead of time. We survey on weekdays, Saturdays and Sundays, which can make access easier.
Freeholders and residents’ companies use a roof report to plan and budget, putting the urgent items at the top.
What you can safely check yourself
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
How it works
Photographs are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. Most surveys take as long as needed for the roof’s area and construction, which we’ll explain when we quote. A typical visit in Leatherhead begins with the street side of the roof and then moves round the building. The back garden is frequently where extensions, dormers and rear slopes are best seen. Then, if it can be reached safely, we look in the loft.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.

Questions from Leatherhead
Do you carry out roof surveys in Leatherhead?
Yes. Our area covers London and South East England, and Leatherhead is part of that. Just phone 07833 053749 or email us and let us know about the property.
Is my home in Leatherhead listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
What does electronic leak detection do?
A sound membrane blocks the test current, but a hole lets it through. That’s how we locate breaches you can’t see.
What’s in the report?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Do you test for asbestos?
No. Asbestos surveys and sampling are not something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
Will you repair the leak?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
Is it a structural engineer’s report?
No. We’re roof surveyors, not structural engineers, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we will recommend one.
