How electronic leak detection works in Crondall
Our ELD testing covers flat roofs in Crondall and the rest of London and South East England. A visit typically takes a length of time set by the roof’s area and construction, which we’ll explain when we quote. Every roof is quoted on its size and build-up. You get a written report with photos. We survey commercial flat roofs, roof terraces and balconies and liquid-applied waterproofing, and common reasons people get in touch are leaking laps in the waterproofing and leaks through a covered membrane.
Some older homes in villages like Crondall are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, for instance when you want to check whether anything has changed.

Why act early in Crondall
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss, on suitable membranes. Around Crondall, older homes often have old roof timbers, and water through a failed covering can rot timber if it is left.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.

Practical tips
A little preparation and a few simple habits help. Our tips:
- Find the breach before more patching
- Stay off the flat roof unless needed
- Have roof specifications to hand
- Make sure trades protect the waterproofing
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
What happens on the day
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Rural addresses near Crondall can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before we arrive
- Move anything stored under the loft hatch
- If you are buying, check with the agent that we can get in
- Make sure we can get to the back of the property

Local flat roofs in Crondall
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. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses like Farnham Castle, about 2.7 miles east, show how far back building in the area around Crondall 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.
Shop and office owners around Hart Shopping Centre may find that flat roofs over shops and units are easy to forget until water comes through a ceiling. Take an older house close to Church of All Saints: flat-roofed rear additions and dormers added over the years are worth checking. If you own a rental within reach of Farnham station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
