About our electronic leak detection in Hersham
Electronic testing locates holes in the waterproofing but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. We will tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. We’ll point you to the likely next step. If you’ve noticed stains far from any visible defect and leaking laps in the waterproofing, we can find out what’s behind it, on flat roof membranes, roof terraces and balconies and commercial flat roofs alike.
In a smaller place like Hersham, some flat roofs sit in the open, 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. A flat roof that still holds water days after rain is also worth a closer look.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

How the survey changes by roof type
Single-ply membranes
Some single-ply membranes suit electronic testing well, depending on the type and build-up.
Inverted and paved roofs
Paving and terraces cover the membrane. Suitability depends on the layers.
What you can safely check yourself
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking and it will help the survey.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.

Before and after the survey
Small things make a difference. Our tips:
- Find the breach before more patching
- Limit access to the roof
- Keep a note of leaks after rain
- Keep outlets clear of debris
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.
The survey, step by step
A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from every safe vantage point, take photos as we go and make notes for the report. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. In a smaller place like Hersham, parking is seldom the issue; lanes, gates and long drives are worth mentioning. On bungalows and lower roofs, much can be seen from the ground, with the loft showing the underside.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
How to prepare
- Keep pets in another room
- For flats, make sure roof access has been agreed
- Buyers: confirm access with the estate agent or seller

What we’re asked to look at in Hersham
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
Signs worth acting on include:
- Stains far from any visible defect
- Leaks through a covered membrane
- Waterproofing to test before it is covered
- Holes around roof penetrations
If you look after a building like Bell Farm Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

Flat roofs in Hersham
The Homewood, about 1.4 miles south-east, is one of the historic houses in the wider area around Hersham. 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. Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If yours is one of the older homes in the streets near Church of St Peter, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. For landlords with property near Walton-On-Thames station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Why it’s worth a survey now in Hersham
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. In a smaller place like Hersham, wherever a roof is exposed, a loose ridge or flashing does not stay loose for long. Wind gets under it and lifts more, and water follows.
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.
