About our electronic leak detection in South Holmwood
A leak in a flat roof often shows up a long way from where the water gets in. That makes leaks hard to trace by eye. ELD tests the waterproofing directly, to find where it has been breached. It’s testing only, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. We then send you the results in a written report. If you’ve noticed water coming in under a flat roof and leaks under green or ballasted roofs, we can find out what’s behind it, on flat roof membranes, roof terraces and balconies and green roofs alike.
Older buildings in small places like South Holmwood may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. 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. Changes that affect a listed building’s special interest need listed building consent.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

What electronic leak detection looks like in South Holmwood
Historic houses such as Polesden Lacey, about 5 miles north-west, show how far back building in the area around South Holmwood goes. If you own one of the older houses, expect a mix of original materials and later repairs on the roof. In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you live in an older home near Church of St Mary Magdalene, the flat roofs on later extensions tend to wear out long before the main roof. Anyone responsible for a site like The Priory CofE Voluntary Aided School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. For landlords with property near Holmwood station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

What happens after the survey?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Will you fly a drone over my roof?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
How experienced are you?

Will you photograph what you find?
Yes, every report has them. Each finding is shown in a picture where possible.
Roof by roof
Bituminous membranes
Many flat roofs use bitumen-based membranes. The build-up decides which method will work.
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
Surveys for landlords and agents in South Holmwood
Buyers’ agents can book surveys on behalf of their clients. Reports are emailed, so they’re easy to pass on, photos included.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
Should I look at the roof myself first?
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
The one thing to avoid is getting up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where it applies.
What happens if roof problems are left?
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. Matching old materials, such as handmade tiles or stone slates, can take time to source. That’s one more reason to find defects before they become urgent.
The cost of a survey depends on the roof: 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.

Practical tips
Most of what helps is simple and safe from the ground. Our suggestions:
- Keep outlets clear of debris
- Get leaks traced quickly
- Use boards when working on the roof
- Find the breach before more patching
If anything in the report is not clear, ask us. We will explain what was found and what it means.
Ask trades working on the roof to protect the membrane when fitting equipment. Check the roof after they’ve finished.
The survey, step by step
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. A typical survey takes more time on a big roof than a small one, with the construction of the roof playing a part too. In a small place like South Holmwood, access is usually the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- 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.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
How to prepare
- Have any questions written down, so nothing gets missed
- Show us where any leaks or stains appear
- Unlock side gates and any roof access doors
