Electronic leak detection in Eltham: what you get
Some flat roofs cannot be tested electronically. Some membranes conduct electricity themselves and some roofs don’t have a suitable layer beneath the membrane. If your roof isn’t suitable, we will tell you at the start. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It saves a wasted visit. If you’re worried about stains far from any visible defect and water coming in under a flat roof, a survey will tell you what’s going on, whatever the roof.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Eltham, access is agreed with whoever manages the roof before the visit. Plant bases, rooflights and cable entries are all places where water can get in.
Where we cannot see part of the flat roof membrane, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

The survey, step by step
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes as long as needed for the roof’s area and construction, which we set out in the quote. From the street, a London terrace normally shows only its front slope or parapet, so a visit in Eltham moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- 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.
Before the survey
- Keep pets inside or away from the areas we are looking at
- Have any paperwork from past roof work to hand
- If it is not your property yet, arrange access through the agent
Booking a survey
If you are buying, it’s useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or drop us an email when you’re ready.

Flat roofs in Eltham
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. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. With Eltham Palace about 0.4 miles north-west, Eltham sits in an area with a long building history. Older homes in the wider area frequently have features worth a closer look, like 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.
If you look after a building such as St Thomas More Catholic Comprehensive School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Landlords with a home close to Mottingham station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.

What we are asked to look at in Eltham
Holes in a membrane frequently come from feet, tools or debris. Many are tiny but water still finds them.
Look out for signs like these:
- Punctures from foot traffic or tools
- Damp inside with no sign on the roof
- Leaks through a covered membrane
- Leaks at pipes, outlets or fixings
For a London address like Eltham, it’s useful to know about controlled parking before the day, along with any off-street space.

Roof by roof
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Some methods can work through these layers but it depends on the layers.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Prices for electronic leak detection in Eltham
To price your survey, we check:
- Any need for thermal images or a drone flight
- Extensions, dormers and garages with roofs of their own
- Building height and the viewpoints available
- 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 it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What we need to know
When you call or email, these details help:
- Pictures of the roof from a safe spot, if you have them
- Anything about access we should know
- Your timetable, such as an exchange date
- What kind of property and roof it is
A quick phone call is usually the easiest start: phone 07833 053749 or drop us an email and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.
Questions from Eltham
Can parking be tricky for a visit in Eltham?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. The visit is then planned around what’s available.
Do you carry out roof surveys in Eltham?
Yes, Eltham is one of the places we work. The survey and report are the same in Eltham as anywhere else.
Which method do you use?
The method is chosen to suit the roof. Low-voltage methods are normally carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
When does the report arrive?
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. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first, with the building owner or managing agent. Mention it when you contact us and we will plan the survey around it.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
