Electronic Leak Detection in Balcombe Lane
Electronic leak detection in Balcombe Lane from an independent, experienced roof surveyor. Over 5,000 surveys and 20+ years behind us across London and the South East.
- Leaks under green or ballasted roofs
- Leaks that return after repairs
- Gaps at membrane joints
Practical tips
A survey works best with a little help from you, before and after. Some tips:
- Find the breach before more patching
- Do not let outlets block
- Note where leaks show inside and when
- Ask contractors to protect the membrane
If water has been getting in, insulation under the membrane may be wet. 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.
Electronic leak detection in Balcombe Lane
A leak in a flat roof often shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself, to find where it has been breached. We test and report, 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. We survey roof terraces and balconies, flat roof membranes and single-ply roofs, and the problems we are asked to look at most are patched roofs that still leak and leaks showing away from the breach.
In a small place like Balcombe Lane, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, normally show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

What we look for on each type of roof
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Local flat roofs in Balcombe Lane
Historic houses such as Tyes Place, about 3 miles south-west, show how far back building in the area around Balcombe Lane goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. Some old buildings in Sussex have Horsham stone slab roofs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
Shop and office owners around County Mall may find that flat roofs over shops and units are easy to forget until water comes through a ceiling. If you own a rental within reach of Balcombe station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Take a building like Balcombe CofE Controlled Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

How it works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe vantage point, take photos as we go and record our findings for the written report. It normally takes a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting. Cottages and farmhouses around Balcombe Lane often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
How to prepare
- Check we can get to the back of the property
- If you’re buying, let the agent know when we’re coming
- Keep pets out of the way during the survey

Common questions in Balcombe Lane
How do I find out if my home in Balcombe Lane is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Do you cover smaller places like Balcombe Lane?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Just mention lanes, gates or anything else about the route when booking.
What’s the best way to book?
To arrange a survey, phone 07833 053749 or use the contact form and let us know the address and what you want to find out. We’ll confirm the price and find a day that suits.
Will you repair the leak?
No. We test the membrane and report. You get the breach locations with photos for your roofer to repair.
Will you go up on the roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the roof space and a drone where it applies, and the report records anything we couldn’t see.
Is my roof suitable for ELD?
That depends on the roof’s membrane and layers. Let us know what you know about the roof and we will check whether ELD will work.
Does someone need to be in?
Not necessarily. If we only need the outside, we can agree that beforehand, but anything inside needs someone there to give access.
Can I check my roof myself?
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
