Electronic leak detection to pinpoint holes in flat roof membranes across Holland Park, using drones and thermal imaging where it applies. Get in touch for a price.
- Punctures from foot traffic or tools
- Leaks showing away from the breach
- Waterproofing to test before it is covered
What happens on the day
You do not need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we will get on with the inspection. A typical survey takes longer on a large roof than a small one, with the construction of the roof playing a part too. For a visit in Holland Park, 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.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photos in a report for your roofer.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Find any records of previous roof work
- Make sure the loft hatch can be reached

Advice
How electronic leak detection works in Holland Park
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. Repair costs aren’t part of the report; that’s for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. Results come in a written report with photos. If you are worried about leaks showing away from the breach and breaches hidden under paving or planting, a survey will tell you what’s going on.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Holland Park, the flat roof is often a shared part of the building.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Questions from Holland Park
Do you look at commercial flat roofs near Holland Park, like hotels?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you’ll get a quote based on the building, and roof access is agreed with you before the visit.
Does a conservation area affect roof work in Holland Park?
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’s the best way to book?
The quickest way is to phone 07833 053749 or email us. Tell us the address and a little about the roof. Surveys run seven days a week.
Can you survey at the weekend?
Surveys run on weekdays and at weekends. To find a day that suits you, phone 07833 053749 or drop us an email.
Does this replace a RICS home survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
Will you repair the leak?
No. ELD is testing only. The report shows where each breach is for your roofer to repair.
Which method do you use?
The roof decides the method. You’ll know which method we plan to use before we start.
Flat and commercial roofs around Holland Park
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. With Leighton House about 0.4 miles south, Holland Park sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
Shop and office owners around Kensington Arcade may find that flat roofs over shops and units are easy to forget until water comes through a ceiling. Hotels and guest houses near Holland Park cannot easily close rooms for a leak, so it’s worth knowing the roof’s condition.

Common roof problems in Holland Park
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
We are often asked to look at:
- Leaks through a flat roof with no obvious cause
- New membranes needing a check before handover
- Leaks showing away from the breach
- Holes left by work on the roof
Take an older house close to Church of St George: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Questions to ask before booking
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether the price includes VAT
- Which parts of the roof they’ll actually see
- What follow-up you get after the report
Checking the roof from ground level
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in, using safe viewpoints and a drone where applicable.
What we cannot see
Some things can’t be seen without opening up the roof, so a survey has limits:
- Build-ups without a suitable layer below
- Sections we cannot safely access
- Water entering through details rather than the membrane
If in doubt, phone 07833 053749 or email us and we will suggest the right survey before booking. What a survey covers and doesn’t.
What we look at
- Roof terraces and balconies
- Flat roof membranes
- Single-ply roofs
- Green roofs
- Liquid-applied waterproofing
- Commercial flat roofs
For landlords and managing agents
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photographs included.
Letting agents can arrange access with tenants, at a time agreed beforehand. We survey on weekdays and at weekends, which can make access easier.
Practical tips
Here are a few things we’d tell any owner:
- Do not keep patching the same spot
- Clear flat roof outlets regularly
- Ask contractors to protect the membrane
- Have roof specifications to hand
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that, and moisture readings can help.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
