About our electronic leak detection in Lightwater
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. We’ll tell you if we think the leak is coming from somewhere else. It will not show water getting in through brickwork or around frames. Our report keeps that distinction clear. We’ll point you to the likely next step. If you are worried about stains far from any visible defect and leaks at pipes, outlets or fixings, we can find out what’s behind it, on green roofs, liquid-applied waterproofing and roof terraces and balconies alike.
Flat roofs in smaller places like Lightwater can be more exposed, particularly where nothing shelters them, where wind can catch loose edges and trims. Felt and bitumen also age in strong sun. The signs are splits, blisters and edges coming away. Standing water that lingers for days after rain is another sign worth watching for.
We keep jargon out of it: where something needs attention, it says so plainly.

Why it is worth a survey now in Lightwater
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. Blocked gutters on homes around Lightwater overflow and soak walls. Dealing with the cause is simple; drying out a wall is not.
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. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Before and after the survey
Over many surveys, some simple habits stand out as worth the effort:
- Act on new leaks promptly
- Check new waterproofing before handover
- Let us know about the membrane and build-up if you know it
- Note where leaks show inside and when
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.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
What we do, step by step
Every roof is different, but as a rough guide the survey takes more time on a big roof than a small one, with the construction of the roof playing a part too. You are welcome to ask questions while we’re there. In a smaller place like Lightwater, as anywhere, the forecast plays a part: the parts that need calm, dry weather are planned around it.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
How to prepare
- If you are buying, let the agent know when we are coming
- For flats, check roof access has been agreed
- Have keys ready for side gates, garages or roof access doors
How to book
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, phone 07833 053749 or send us an email with the address and the days you’d prefer.
Advice
What this survey can’t tell you
Every survey has limits, and we’d rather be clear about that before booking. Keep these in mind:
- Parts of the roof covered by fixed equipment
- Repairing the breaches (that is for your roofer)
- Moisture spread under the membrane

Do you need electronic leak detection in Lightwater?
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
These are some of the problems a survey can pick up:
- Leaks under green or ballasted roofs
- Patched roofs that still leak
- Gaps at membrane joints
- Leaks showing away from the breach
If you own a rental within reach of Bagshot station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Local flat roofs in Lightwater
What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand, before anyone quotes for re-roofing. In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. 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.
Anyone responsible for a site like Hammond School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you live in an older home near All Saints, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Your questions about electronic leak detection in Lightwater
Is my home in Lightwater listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Will you come out to Lightwater?
Yes, Lightwater is covered. We survey roofs across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
Does ELD work under paving or planting?
It can be possible, depending on the roof. Covered roofs limit the methods we can use so we check the roof first.
How much time does ELD need?
Testing normally takes longer on a large roof than a small one, with the construction of the roof playing a part too.
What is electronic leak detection?
A sound membrane blocks the test current, but a hole lets it through. That is how we locate breaches you cannot see.
What happens after the survey?
You’ll receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
