Electronic leak detection for homes and businesses in Charing Cross
Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. If your roof is not suitable, we will tell you at the start. Telling us what you know about the roof’s membrane and layers helps, like drawings or specifications. It avoids arranging a test that cannot give results. We survey roof terraces and balconies, flat roof membranes and commercial flat roofs, and the problems we’re asked to look at most are leaks through a flat roof with no obvious cause and new roofs to check before paving or planting.
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 Charing Cross, the flat roof is often a shared part of the building.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

The survey, step by step
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from each safe vantage point, photograph what we find and make notes for the report. It usually takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. In Charing Cross, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Before we arrive
- Agree roof access with the managing agent if it is shared
- Make a note of anything you’d like us to look at
- Keep pets in another room
How to book
If you have photos of the roof, send them over. Take them safely from ground level or a window. To send them or to book, call 07833 053749 or send us an email.

Local flat roofs in Charing Cross
Inner London’s Victorian and Edwardian terraces frequently have Welsh slate roofs. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. With Benjamin Franklin House about 0.1 miles east, Charing Cross sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead.
Anyone responsible for a site like Soho Parish CofE Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. For hotels and guest houses around Charing Cross, a roof problem found early is far less disruptive than one found by a guest, so it is worth knowing the roof’s condition.

Tips that help
Nothing here needs a ladder. A few suggestions:
- Share any drawings of the roof
- Limit access to the roof
- Clear flat roof outlets regularly
- Consider ELD before paving or planting goes on
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.

Prices for electronic leak detection in Charing Cross
We confirm the price for the job before booking. This is what makes a difference:
- Features like valleys, chimneys, dormers and parapets
- Building height and the viewpoints available
- How big the roof is
- Extra roofs, like extensions, dormers or garages
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Booking your survey

- The style of property, from a terrace to a block
- Where water is showing inside, if it is
- Photos of the roof, taken safely from ground level or a window
- What’s prompted the survey
Getting a price is simple: just call 07833 053749 or use the contact form, tell us about the property and we will explain which survey suits. We confirm the price before anything is booked.

FAQs for Charing Cross
Will parking be an issue for a roof survey in Charing Cross?
Normally it is manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.
Does a conservation area affect roof work in Charing Cross?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. Roofs over flats are frequently shared, so we need permission from the freeholder or managing agent. We inspect only the parts we are allowed to reach.
Is my roof suitable for ELD?
That depends on the roof’s membrane and layers. Share any details you have and we will check whether ELD will work.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
Can you test a green or ballasted roof?
In some cases. The layers on top and the build-up below decide it and parts may need to be lifted. We’ll discuss it before we quote.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. We’ll talk about access when booking.
