How electronic leak detection works in Chesham
ELD can be carried out in more than one way. Low-voltage methods normally need a wet roof surface and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof, and we will explain our choice. If neither method suits your roof, we will tell you before any testing starts. If you’ve noticed a flat roof leak that can’t be traced and gaps at membrane joints, a survey will tell you what’s going on, whatever the roof.
Around Chesham, many garages, porches and extensions have flat roofs of their own. Cement sheet roofs on buildings from before 2000 may contain asbestos, which a specialist asbestos surveyor should check before anyone disturbs them. Felt, rubber and fibreglass coverings each need a different approach. We do not test for asbestos, but our reports may flag materials that could contain it.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Practical tips
Nothing here needs a ladder. Our suggestions:
- Don’t let outlets block
- Act on new leaks promptly
- Keep a note of leaks after rain
- Test new membranes before covering them
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
Electronic leak detection around Chesham
The wider area around Chesham has a long history of building, with Cholesbury Manor House about 3.5 miles north-west. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Some villages in Buckinghamshire still have thatched roofs. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Landlords with a home close to Amersham station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

What we do, step by step
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. Most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. Semi-detached and terraced homes in a town like Chesham frequently share a roof line with the neighbours, so we check what can be seen of the shared parts from your side. Let us know about any known leaks, past repairs or building work as you book.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
How to prepare
- Gather any invoices or paperwork from past roof work
- Tell us about any leaks, stains or damp patches you know of
- Jot down any questions you want answered
How to book
To arrange a survey, ring 07833 053749 or send us an email and tell us the address and what’s prompted the survey. We will confirm the price before booking.

What we cannot see
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- Leaks from walls, copings or rooflights
- Sections we can’t safely access
- Repairing the breaches (that’s for your roofer)
If in doubt, call 07833 053749 or drop us an email and we’ll point you to the right survey. What our survey covers.
What this survey covers
- Liquid-applied waterproofing
- Single-ply roofs
- Green roofs
- Commercial flat roofs
- Flat roof membranes
- Roof terraces and balconies
Roof by roof
Single-ply membranes
ELD frequently works on single-ply membranes, depending on the type and build-up.
Inverted and paved roofs
We will tell you if your inverted or paved roof isn’t suitable.
Do you need electronic leak detection in Chesham?
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
A survey can pick up problems such as:
- Breaches around outlets and penetrations
- Leaks through a covered membrane
- Water coming in under a flat roof
- Patched roofs that still leak
Take a building like Elmtree Infant and Nursery School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
What to check before booking

Common questions in Chesham
Is there anything to prepare before you come to Chesham?
Very little. Unlock side gates, keep pets in another room and dig out any invoices from past roof work.
Is Chesham in the area you cover?
We do. Every survey there gets the same written report with photographs.
Do you carry professional indemnity insurance?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Will you check the loft?
Where it’s relevant to the survey and there is safe access, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
Does the weather affect the survey?
Light rain does not typically stop a survey, and it can even help show where water is getting in. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so we’ll agree a new date if the weather isn’t suitable.
Can you give me structural calculations?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
How long does electronic leak detection take?
Testing normally takes as long as needed for the roof’s area and construction, which we set out in the quote.
