Electronic leak detection for homes and businesses in Bayswater
Some flat roofs cannot be tested electronically. Certain membranes conduct electricity and some roofs do not have a suitable layer beneath the membrane. We will say if ELD won’t work on your roof at the start. Any details you have about the membrane and build-up help us decide, such as drawings or specifications. It avoids arranging a test that cannot give results. We survey single-ply roofs, commercial flat roofs and green roofs, and people most often book us about patched roofs that still leak and holes left by work on the roof.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. In Bayswater, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend.

Common questions in Bayswater
Is parking a problem for a survey in Bayswater?
Parking in Bayswater, 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 booking.
Can you look at the flat roof of a hotel or office near Bayswater?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
Do you use drones?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Will you walk on the roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where applicable let us see the rest.
Are you structural engineers?
No. We point out what can be seen, such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Do you need to get into the loft?
Where it’s relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch.
What affects the cost of electronic leak detection
We confirm the price for your survey before booking. This is what makes a difference:
- Extensions, dormers and garages with roofs of their own
- Whether thermal imaging or a drone is needed
- Whether it is a home or a commercial building
- The roof’s overall size
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
Helping us price your survey
You do not need to know any roofing terms. It’s enough to let us know:
- Your postcode, so we can check access and travel
- Dates you’re working to, like exchange
- What kind of property and roof it is
- Pictures from the garden or a window, if you have them
Photos help, if you have them. Take them safely from ground level or a window; never climb up to get a better view. To get started, ring 07833 053749 or send us an email.
How the survey changes by roof type
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check before we quote.
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
Signs you need electronic leak detection in Bayswater
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Some are too small to see but water still finds them.
People typically book a survey after spotting one of these:
- Repairs that haven’t stopped the leak
- Damp inside with no sign on the roof
- Holes around roof penetrations
- New roofs to check before paving or planting
A roof leak in a hotel or guest house around Bayswater means lost rooms as well as repairs, so it pays to find faults before guests do.
What to check before booking
- Whether the roof space is looked at, where there is one
- What happens after the report arrives
- Whether you get a written report with photos
- Whether the price includes VAT
How it works
The aim of the visit is simple: to see as much of the flat roof membrane as can safely be seen and record it clearly. Notes and photographs go into the written report. It usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. For a visit in Bayswater, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from the ground, from windows, from inside the roof space and from the roof where it’s safe.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photos in a report for your roofer.
How to prepare
- Have any questions written down, so nothing gets missed
- Keep pets inside or away from the areas we’re looking at
- If it is not your property yet, arrange access through the agent
Booking a survey

For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps when budgeting.
Can I check my roof myself?
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.

For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
The streets around a church such as Essex Street Chapel are often among the oldest in a place, and if yours is one of the older homes nearby, flat-roofed rear additions and dormers added over the years are worth checking.
