Electronic leak detection for homes and businesses in Bexley Riverside
You get a report showing the location of each breach with photos. Your roofer can then repair those points instead of hunting for the leak. We don’t estimate repair costs, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. Common reasons to book are breaches around outlets and penetrations and breaches hidden under paving or planting, across liquid-applied waterproofing, roof terraces and balconies and flat roof membranes.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. In Bexley Riverside, 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.
Every survey ends with a written report, with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Flat roofs in Bexley Riverside
The wider area around Bexley Riverside has a long history of building, with Hall Place and Gardens about 1.6 miles south. 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. Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Bexley Riverside is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
As a London address, Bexley Riverside can be tricky for parking: let us know about parking bays, permits or a driveway as you book. If you look after a shop, office or commercial unit, for instance near Broadway Shopping Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling.
Bexley Riverside is about 3 miles north-west of Dartford, in Greater London. We visit Bexley Riverside as part of our work across Greater London. Our area takes in places right across Greater London. There is also a page for London.

Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Green and ballasted roofs
Some layers may need lifting for testing. We discuss this before quoting.

Bexley Riverside: your questions answered
Do you cover Bexley Riverside?
Yes, Bexley Riverside is within the area we cover. We work right across London and South East England. You can call 07833 053749 or use the contact form with the address and a few details.
Can parking be tricky for a visit in Bexley Riverside?
Sometimes, yes. If Bexley Riverside has controlled parking where you are, a visitor permit is the easiest answer.
Does the weather affect the survey?
A survey can typically go ahead in light rain. High 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.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We look at the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
Can you give me structural calculations?
No. We are roof surveyors, not structural engineers. If we see signs that need an engineer’s opinion, we’ll recommend one.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance.
Tips from our surveys
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Do not keep patching the same spot
- Consider ELD before paving or planting goes on
- Have roof specifications to hand
- Record dates and spots where water appears
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
What affects the cost of electronic leak detection
A few things affect what a survey costs:
- Whether it’s a home or a commercial building
- The number of roofs, including extensions and garages
- The use of thermal imaging or a drone
- The height of the building and how the roof can safely be seen
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.
Getting in touch
There is no need for technical words. It’s enough to tell us:
- The style of property, from a terrace to a block
- Your timetable, like an exchange date
- Access details, like a loft hatch or a shared roof
- What’s prompted the survey
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. Otherwise, simply call 07833 053749 or use the contact form whenever suits you.
Signs you need electronic leak detection in Bexley Riverside
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs, depending on the build-up.
Signs worth acting on include:
- Water coming in under a flat roof
- Leaking laps in the waterproofing
- Patched roofs that still leak
- Leaks showing away from the breach
Take a building like Normandy Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Choosing a roof surveyor
- Are they insured for the work?
- Their drone registration, if they fly one
- Is there a chance to talk the report through?
- Their report turnaround times
How it works
Safety comes first on every visit. We inspect whatever is safely visible, and if part of the roof cannot be seen, the report says so. The survey typically takes a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. In Bexley Riverside, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- First, you let us know about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Before we arrive
- Point out any leaks or damp patches
- Keep pets inside or away from the areas we’re looking at
- If you’re buying, check with the agent that we can get in
Booking a survey
Booking is simple: just call 07833 053749 or email us and give us a few details about the property and we will recommend the right survey. The price is agreed up front.
