Stanwell Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes around Stanwell, with findings in writing and pictures to back them up. Book a weekday or weekend visit.
- Gaps at membrane joints
- Leaks at pipes, outlets or fixings
- Holes left by work on the roof
Common roof problems in Stanwell
Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
Problems we come across often include:
- Leaks through a covered membrane
- Damp inside with no sign on the roof
- Patched roofs that still leak
- Punctures from foot traffic or tools
For site and facilities teams at buildings like Stanwell Fields CofE Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Questions to ask before you book
- Are they insured for the work?
- Whether the loft is part of the inspection
- Their report turnaround times
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
Electronic leak detection in Stanwell
Our ELD testing covers flat roofs in Stanwell and the rest of London and the South East. Testing typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. We quote electronic leak detection for each roof, as the method and time depend on the roof. You get a written report with photos. If you are worried about leaking laps in the waterproofing and leaks that return after repairs, we can find out what’s behind it, on flat roof membranes, roof terraces and balconies and green roofs alike.
Outbuildings, garden rooms and garages in places like Stanwell often have flat roofs of their own. They’re rarely looked at until something gets wet. It is worth mentioning them when you book, so the visit can include them, along with the main flat roof. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we check the roof.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in.

Your questions about electronic leak detection in Stanwell
Do you look at commercial flat roofs near Stanwell, such as hotels?
Yes. As well as homes, we check flat roofs on offices, hotels, blocks of flats and commercial units. Larger commercial roofs are quoted for the building.
Will you come out to Stanwell?
We do. Villages and rural addresses get the same survey as a town house.
How long will testing take?
It depends on the size of the roof and its build-up. We’ll give you an idea when we quote.
How do I arrange electronic leak detection in Stanwell?
Simply phone 07833 053749 or use the contact form. We will ask a few questions, confirm the price and agree a date.
What insurance do you have?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We check the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys, across London and South East England.
What we look for on each type of roof
Green and ballasted roofs
Some layers may need lifting for testing. We discuss this before quoting.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane, which affects testing.
Electronic leak detection in Stanwell: local notes
There are several hotels within about a mile and a half of Stanwell. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Some old buildings in Surrey and Sussex have 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, the joins between later flat roofs and the old walls are where problems usually start. A roof leak in a hotel or guest house around Stanwell means lost rooms as well as repairs, so it pays to find faults before guests do.

What we do, step by step
Photos are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. A typical visit takes more time on a big roof than a small one, with the construction of the roof playing a part too. Parking around Stanwell is normally easier than in a town centre, but mention lanes, gates or long drives. Low roofs on bungalows can often be seen well from the ground, and the loft shows the rest.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
Before the survey
- Have keys ready for side gates, garages or roof access doors
- If you are buying, let the agent know when we’re coming
- If the roof is shared, arrange access with whoever manages the building

Leave it or get it looked at?
Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. With lower homes, common in places like Stanwell, there’s little between a roof defect and the ceiling, so water can show inside quickly once it gets past the covering. Catching the cause first saves redecorating as well.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What you get with us
- More than 20 years surveying roofs
- An independent view of the roof

What this survey can’t tell you
Without opening up the roof, some things stay hidden, so a survey has limits:
- Moisture spread under the membrane
- Roofs whose membrane or build-up is not suitable
- Parts of the roof covered by fixed equipment
