About our electronic leak detection in Covent Garden
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work, and some may need lifting. We talk this through before we quote. Any details of the build-up help because they show what’s under the surface. If testing isn’t possible, we’ll say so. We survey flat roof membranes, green roofs and single-ply roofs, and people most frequently book us about leaks that return after repairs and a flat roof leak that can’t be traced.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Covent Garden, access is agreed with whoever manages the roof ahead of the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
Findings are set out part by part, from the coverings down to the gutters, each with a short note and a photograph. You’ll see the good as well as the bad.

Before and after the survey
You don’t need to be a roofer to help. Here’s what helps most:
- Keep foot traffic on flat roofs to a minimum
- Tell us about the membrane and build-up if you know it
- Use boards when working on the roof
- Get leaks traced quickly
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
Check contractors protect the waterproofing when fitting equipment. Check the roof after they’ve finished.
FAQs for Covent Garden
Does a conservation area affect roof work in Covent Garden?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Can parking be tricky for a visit in Covent Garden?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Does someone need to be in?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you when you book.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
Can you find leaks on a covered flat roof?
On some roofs, yes. What sits on the membrane affects the method, so we check the build-up first.
How long will testing take?
Testing normally takes as long as needed for the roof’s area and construction, which we set out in the quote.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage methods are typically carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
What we’re asked to look at in Covent Garden
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
Typical things we are asked to look at include:
- New roofs to check before paving or planting
- Leaks at pipes, outlets or fixings
- Leaks that return after repairs
- Breaches hidden under paving or planting
A roof leak in a hotel or guest house around Covent Garden means lost rooms as well as repairs.
Questions to ask before you book
- Which limits apply to the survey
- Is there a chance to talk the report through?
- Whether any drone flown is registered with the CAA
- How much experience they have with roofs like yours
What happens if roof problems are left?
Not every leak is in the membrane. Testing shows whether the membrane is breached so attention can go to the right place. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for the job before booking.

Electronic leak detection in Covent Garden: local notes
Historic houses such as Benjamin Franklin House, about 0.4 miles south, show how far back building in the area around Covent Garden goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. If your home in Covent Garden is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
If you run a business near Kingly Court, the flat roofs over shops and commercial units are worth checking before a leak, not after. For an older house near a landmark such as Crown Court Church, the joins between later flat roofs and the old walls are where problems typically start.

What else we do in Covent Garden
What happens on the day
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. The survey itself takes as long as needed for the membrane area and the build-up, which we set out in the quote. In a London area like Covent Garden, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from the ground, from windows, from inside the loft space and from the roof where it is safe.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photographs in a report for your roofer.
Getting ready for the survey
- Make sure the loft hatch can be reached
- Have any questions written down, so nothing gets missed
- Dig out any old roof reports or invoices

Landlords, agents and block managers in Covent Garden
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client.
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps when budgeting.
Should I look at the roof myself first?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
