Electronic leak detection in Queensbury
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing will not show on the test. If the evidence points elsewhere, we’ll say so. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. You’ll also know what to check next. If you’ve noticed holes around roof penetrations and water coming in under a flat roof, we can find out what’s behind it.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Queensbury, the roof above may belong to the building rather than one flat.
Where we can’t see part of the flat roof membrane, the report says so. That way, it is clear what was covered and what wasn’t.

Surveys for landlords and agents in Queensbury
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time, and they’re priced for the size.
An agent can book and manage the survey for a landlord. Access is agreed with the tenant beforehand.
Queensbury: your questions answered
Is Queensbury in the area you cover?
Yes. We work right across London and the South East, and Queensbury is part of that. You can call 07833 053749 or send us an email with the address and a few details.
Is parking a problem for a survey in Queensbury?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. The visit is then planned around what’s available.
Do you survey on Saturdays and Sundays?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you when you book.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning, with the building owner or managing agent. Tell us about it as you book and we’ll explain what’s needed.
When does the report arrive?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
Does this replace a RICS home survey?
No. We look at the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing aren’t part of what we do. We flag materials that could contain asbestos, like cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
What a survey costs
We confirm the exact price before booking. This is what makes a difference:
- Features like valleys, chimneys, dormers and parapets
- How tall the building is and how easy the roof is to see
- Extra roofs, like extensions, dormers or garages
- Whether it is a home or a commercial building
To find out what your survey will cost, ring 07833 053749 or use the contact form with the address and some details. We’ll confirm the figure before booking.
What to let us know when you contact us
When you call or email, these details help:
- Any marks or damp showing indoors
- The reason for the survey, such as buying, a leak or storm damage
- Whether there’s a loft hatch, a shared roof or tricky access
- Pictures from the garden or a window, if you have them
If you have photos of the roof, send them over. Take them safely from the ground or a window. To get started, phone 07833 053749 or email us.
What happens if roof problems are left?
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Tips from our surveys
Nothing here needs a ladder. A few suggestions:
- Check trades protect the waterproofing
- Stay off the flat roof unless needed
- Act on new leaks promptly
- Avoid repeated repairs without finding the cause
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
How it works
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. Most visits take a length of time set by the roof’s area and construction, which we set out in the quote. Surveys in Queensbury can be booked for any day of the week. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
How to prepare
- Keep pets in another room
- Let us know where we can park nearby
- Make a note of anything you’d like us to look at
Booking a survey
We confirm the price for the job before booking, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, ring 07833 053749 or email us.

Electronic leak detection around Queensbury
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 2.7 miles west lies Headstone Manor, a reminder of how long the area around Queensbury has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
If you own a rental within reach of Kenton station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Take a building like Glebe Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you live in an older home near All Saints Church, the joins between later flat roofs and the old walls are where problems typically start.
