How electronic leak detection works in Compton
We carry out electronic leak detection on flat roofs in Compton and across London and South East England. A visit typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. We quote electronic leak detection for each roof, as the method and time depend on the roof. You get a photo-illustrated written report. Common reasons to book are damp inside with no sign on the roof and failed seams and laps, across liquid-applied waterproofing, single-ply roofs and roof terraces and balconies.
In a small place like Compton, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later, like when you want to compare after future work.

The survey, step by step
After the inspection, everything we found is written up as a photo-illustrated written report, sent to you by email. As for time on site, most surveys take more time on a big roof than a small one, and the build-up of the roof makes a difference too. For a village or hamlet like Compton, the journey is planned in advance: let us know about narrow lanes, gates, long drives and where we can park. The roof is looked at from the ground, from windows, from the loft where there’s safe access and from the roof where it is safe.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
How to prepare
- Keep pets out of the way during the survey
- Let us know about parking near the property
- If the roof is shared, arrange access with whoever manages the building

What this survey cannot tell you
No survey can tell you everything, and we’d rather be clear about that before booking. Bear these in mind:
- Repairing the breaches (that’s for your roofer)
- Areas we can’t reach or that can’t be tested
- How wet the insulation is
If you are not sure which survey you need, ring 07833 053749 or email us and we’ll give you a straight answer before you book. The full list of what we check.
What we look at
- Roof terraces and balconies
- Green roofs
- Commercial flat roofs
- Liquid-applied waterproofing
- Single-ply roofs
- Flat roof membranes
Should I look at the roof myself first?
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
Your own check is a good start, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
Why it is worth a survey now in Compton
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. For older village homes like those around Compton, the right replacement materials are not always easy to find quickly. Spotting a problem early leaves room to find them.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.

Your questions about electronic leak detection in Compton
Is my home in Compton listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Is Compton in the area you cover?
Yes, Compton is within the area we cover. Our area covers London and the South East. You can ring 07833 053749 or use the contact form with the address and some details, and we will talk through which survey suits.
Does electronic leak detection work on all membranes?
That depends on the roof’s membrane and layers. Share any details you have and we will confirm suitability.
How many surveys have you done?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and the South East.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
What if it rains on the day?
Some surveys depend on the weather more than others. Drones cannot fly safely in strong wind or a downpour, and thermal imaging works best after a sunny day, with a dry roof and little wind. We’ll rearrange with you if the weather is not right.
What happens after the survey?
You receive the written report by email, with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Tips from our surveys
A little preparation and a few simple habits help. Our tips:
- Keep foot traffic on flat roofs to a minimum
- Share any drawings of the roof
- Record dates and spots where water appears
- Test new membranes before covering them
Where the evidence points to walls, copings or rooflights, we’ll note it, so other causes can be checked.
Consider testing a new membrane before it is covered. It’s easier to find holes before more layers are added.
What electronic leak detection looks like in Compton
Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. The wider area around Compton has a long history of building, with Loseley Park about 1 mile east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Take a building like Loseley Fields Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If yours is one of the older homes in the streets near Church of St Nicholas, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
