Electronic leak detection in Oval: what you get
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. If your roof isn’t suitable, we’ll tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It saves a wasted visit. We survey flat roof membranes, roof terraces and balconies and green roofs, and people most often book us about leaks under green or ballasted roofs and damp inside with no sign on the roof.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Oval, the flat roof is often a shared part of the building.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

FAQs for Oval
Can parking be tricky for a visit in Oval?
Parking in Oval, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Is my home in Oval listed or in a conservation area?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
How experienced are you?
Over 20 years and more than 5,000 surveys, across London and South East England.
How does ELD work?
The waterproofing membrane normally stops an electrical current, so wherever there is a hole, it passes through. That is how we locate breaches you cannot see.
How long will testing take?
It depends on the size of the roof and its build-up. You will know roughly how long before we start.
How quickly is the report sent?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, tell us when you book.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, and it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Rented homes, blocks and businesses
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
Any of our surveys can be booked by landlords, agents and building managers in Oval. To discuss a property or a block, phone 07833 053749 or drop us an email.
Checking the roof from the ground
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.

Why get it checked now?
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.

The survey, step by step
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. In a London conversion, the way into the roof space is often from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Oval runs like any other.
- 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
- Make a note of anything you’d like us to look at
- Check we can get to the back of the property
- Tell us about any leaks, stains or damp patches you know of
Getting a price
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just ring 07833 053749 or email us when you are ready.

Bituminous membranes
Bituminous roofs frequently have laps and old repairs that can leak. Testing depends on the roof.
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
Electronic leak detection in Oval: local notes
About 1.7 miles north-west lies Buckingham Palace, a reminder of how long the area around Oval has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Within a mile and a half or so of Oval there are several hotels, and hotels, like offices and blocks of flats, often have flat roofs. If you look after one, a leak through a flat roof can put a room out of use.
For hotels and guest houses around Oval, a roof problem found early is far less disruptive than one found by a guest, so it is worth knowing the roof’s condition. If you look after a shop, office or commercial unit, for instance near Gabriel's Wharf, outlets and upstands on commercial flat roofs are the places to check before trouble starts. Landlords with a home close to Vauxhall station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.
