Questions from Kings Cross
Will parking be an issue for a roof survey in Kings Cross?
Parking in Kings Cross, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can you look at the flat roof of a hotel or office near Kings Cross?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
What is electronic leak detection?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached so we can pinpoint it.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed.
Does the weather affect the survey?
Light rain is usually fine; heavy rain and wind are different. Strong wind or heavy rain can make access unsafe and ground a drone, so we’d move the date with you.
What’s in the report?
It sets out what we found, why it matters and what we recommend, backed by photographs. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Does someone need to be in?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Electronic leak detection in Kings Cross: what you get
There are different ELD methods. Low-voltage testing is typically done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof, and we will explain our choice. We’ll say if your roof does not suit either method before any testing starts. Common reasons to book are leaks that return after repairs and gaps at membrane joints, across flat roof membranes, roof terraces and balconies and commercial flat roofs.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. In Kings Cross, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
After the visit, you get a written report with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Electronic leak detection around Kings Cross
With Dr Johnson's House about 1.2 miles south-east, Kings Cross sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. There are several hotels within about a mile and a half of Kings Cross. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
If you let a flat or house near London Kings Cross station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. Hotels and guest houses near Kings Cross cannot easily close rooms for a leak, so it pays to find faults before guests do.

Checking the roof from the ground
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.

Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Moisture spread under the membrane
- Water entering through details rather than the membrane
- Roofs whose membrane or build-up is not suitable

What happens if roof problems are left?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That’s a good reason to find problems early, while there’s time to plan.

What we do, step by step
There is not much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. A typical survey takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. In a London conversion, the way into the roof space is often from a communal landing or the top flat. If that applies to your building, it’s useful to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Preparing for the visit
- Point out any leaks or damp patches
- Leave side gates unlocked
- Dig out any old roof reports or invoices
Book a survey

When to book a survey in Kings Cross
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
It is worth booking a survey if you’ve seen:
- Leaks showing away from the breach
- Breaches around outlets and penetrations
- Damage from equipment installers
- New membranes needing a check before handover
For site and facilities teams at buildings such as Argyle Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
What to check before booking
- Is there a chance to talk the report through?
- What experience they bring
- Which parts of the roof they’ll actually see
- Which limits apply to the survey
