About our electronic leak detection in Primrose Hill
ELD finds breaches in the membrane, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing will not show on the test. We will tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. You’ll also know what to check next. We’re often asked to look into leaks through a covered membrane and waterproofing to test before it’s covered, across green roofs, flat roof membranes and commercial flat roofs.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Primrose Hill, the flat roof is often a shared part of the building.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Tips from our surveys
Over many surveys, some simple habits stand out:
- Avoid repeated repairs without finding the cause
- Record dates and spots where water appears
- Act on new leaks promptly
- Use boards when working on the roof
Keep the report with the roof’s records. It is a dated record of the membrane’s condition.
Ask trades working on the roof to protect the membrane when they work up there. Check the roof after they’ve finished.

Questions from Primrose Hill
Is my home in Primrose Hill listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Do you cover commercial flat roofs around Primrose Hill?
Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.
Will you fly a drone over my roof?
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 every flight depends on the airspace and the weather.
How fast do I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed.
Can you survey in bad weather?
Light rain is normally fine; heavy rain and wind are different. Strong wind or a downpour can make access unsafe and ground a drone, so we’d move the date with you.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Does someone need to be in?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in; we will agree the details when you book.
Why get it checked now?
A visual inspection can miss tiny holes. Electronic testing can find breaches you can’t see by eye, on suitable membranes. In Primrose Hill, as across London, an overflowing gutter soaks the wall below, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.

Landlord and commercial surveys in Primrose Hill
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait.
We survey roofs for landlords and letting agents as well as homeowners. A written report with photos gives you a clear record of the flat roof membrane, useful for planning maintenance.
DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
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.
Different roofs, different checks
Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.
Inverted and paved roofs
If the build-up rules out ELD, we’ll say so.
What happens on the day
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. It typically takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. From the street, a London terrace typically shows only its front slope or parapet, so in Primrose Hill we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, let us know who can let us into the shared parts.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
How to prepare
- Mention any parking restrictions on your street
- Leave a clear route to the loft
- Dig out any old roof reports or invoices

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 phone 07833 053749 or email us when you are ready.
Advice
Local flat roofs in Primrose Hill
The wider area around Primrose Hill has a long history of building, with Winfield House about 0.7 miles south. If your house is among the older ones, expect a mix of original materials and later repairs on the roof. 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. If your home in Primrose Hill is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you run a hotel or guest house in or near Primrose Hill, a roof problem can mean rooms out of use, so it pays to find faults before guests do. If you let a flat or house near Kentish Town West station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. For businesses in and around places such as O2 Centre, a flat roof over a business is out of sight and out of mind until it leaks.
