Harmans Water Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes in Harmans Water, carried out by an experienced roof surveyor. You get a clear written report with photos.
- Gaps at membrane joints
- Leaks through a flat roof with no obvious cause
- New roofs to check before paving or planting
Signs you need electronic leak detection in Harmans Water
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
Problems we come across often include:
- Patched roofs that still leak
- Waterproofing to test before it is covered
- Water coming in under a flat roof
- Punctures from foot traffic or tools
Landlords with a home close to Martins Heron station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Before you book anyone
- How long they’ve been surveying roofs
- Whether VAT is in the quoted price
- Whether you can ask questions once you have the report
- How long the report takes to arrive
How electronic leak detection works in Harmans Water
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help because they show what’s under the surface. We will tell you if the roof cannot be tested. If you’re worried about a flat roof leak that can’t be traced and leaks at pipes, outlets or fixings, a survey will tell you what’s going on, on roof terraces and balconies, green roofs and liquid-applied waterproofing alike.
Outbuildings, garden rooms and garages in places like Harmans Water 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.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

For landlords and managing agents
Buyers’ agents can book surveys on behalf of their clients. Reports are emailed, so they’re easy to pass on.
Letting agents often book on a landlord’s behalf, with the report sent to whoever needs it. Access is agreed with the tenant ahead of time.
DIY checks: what’s safe
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
Your questions about electronic leak detection in Harmans Water
How do I find out if my home in Harmans Water is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Is Harmans Water within the area you cover?
Yes, Harmans Water is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
What’s in the report?
It works through the roof part by part, in writing and with photos. The most urgent items are made clear.
Is the repair part of the test?
No. We test the membrane and report. You get the breach locations with photos so your roofer can fix them.
Do you need to get into the loft?
If the survey needs it and the roof space can be reached safely, yes. Please clear anything stored under the hatch.
Is my roof suitable for ELD?
That depends on the roof’s membrane and layers. Tell us what you know about the roof and we’ll confirm suitability.
How it works
There is not much for you to do on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. A typical survey takes 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 Harmans Water, parking is seldom the issue; lanes, gates and long drives are worth mentioning. On bungalows and lower roofs, much can be seen from ground level, with the loft showing the underside.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Preparing for the visit
- Agree roof access with the managing agent if it is shared
- Have any questions written down, so nothing gets missed
- Move anything stored under the loft hatch
How to book
To arrange a survey, call 07833 053749 or send us an email with the address and what you’d like to know about the roof. We’ll confirm the price before you book.

Flat and commercial roofs around Harmans Water
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. 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, ideally before any re-roofing is planned.
If you look after a building such as Harmans Water Primary School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. If you look after a shop, office or commercial unit, for instance near The Lexicon, the flat roofs over shops and commercial units are worth checking before a leak, not after.

A survey works best with a little help from you, before and after. Some tips:
- Use boards when working on the roof
- Limit access to the roof
- Keep outlets clear of debris
- Record dates and spots where water appears
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
Ask trades working on the roof to protect the membrane when fitting equipment. Check the roof after they’ve finished.
Prices for electronic leak detection in Harmans Water
What a survey costs depends on the time and equipment it needs. That comes down to:
- How big the roof is
- The use of thermal imaging or a drone
- How tall the building is and how easy the roof is to see
- Features like valleys, chimneys, dormers and parapets
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 safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

We’ll usually ask about:
- The reason for the survey, such as buying, a leak or storm damage
- Access details, like a loft hatch or a shared roof
