- Leaks at pipes, outlets or fixings
- Waterproofing to test before it’s covered
The survey, step by step
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. After that, we look at everything we can see safely, using the ground, windows, the loft and a drone where it applies. The survey normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- 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.
Getting ready for the survey

Advice
Electronic leak detection in South Street: what you get
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. We’ll tell you if the roof cannot be tested. Common reasons to book are leaks that return after repairs and breaches hidden under paving or planting, on liquid-applied waterproofing, roof terraces and balconies and single-ply roofs.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. In South Street, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Honest limits
Every survey has limits, and we’d rather be clear about that before you book. Bear these in mind:
- Some conductive membranes
- How wet the insulation is
- Sections we can’t safely access
If in doubt, ring 07833 053749 or email us and we’ll point you to the right survey. What a survey covers and doesn’t.
Roof types and parts we check
- Flat roof membranes
- Liquid-applied waterproofing

- Green roofs
What we look for on each type of roof
Single-ply membranes
Some single-ply membranes suit electronic testing well, depending on the type and build-up.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
South Street questions
Is parking a problem for a survey in South Street?
Sometimes, yes. If South Street has controlled parking where you are, a visitor permit is the easiest answer.
Is my home in South Street listed or in a conservation area?
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.
What happens next?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
How many surveys have you done?
We have more than 20 years’ experience and have completed over 5,000 surveys across London and the South East.
What does the report include?
It works through the roof part by part, in writing and with photos, finishing with recommendations. Points are put in order of urgency where relevant.
Can you tell me if my roof has asbestos?
No. We do not sample or test for asbestos. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.

Why act early in South Street
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. When the stain finally shows, the damage underneath is frequently older than it looks.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for the job before booking.

Flat roofs in South Street
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Titsey Place, about 2.1 miles south-west, is one of the historic houses in the wider area around South Street. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
Landlords with a home close to Oxted station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For site and facilities teams at buildings such as Charles Darwin School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. If you live in an older home near Church of St Mary the Virgin, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
South Street is about 4 miles north-east of Oxted, in Greater London. We carry out electronic leak detection in South Street for houses, flats, blocks and commercial buildings. South Street is one of the towns and villages in Greater London we cover. There is also a page for London.

Landlords, agents and block managers in South Street
Landlords, agents and building managers in South Street and across Greater London can book any of our surveys. For a price for a let property or a block, ring 07833 053749 or email us.
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time.
Can I check my roof myself?
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
