Electronic Leak Detection in Staples Corner
Electronic leak detection in Staples Corner, with over 20 years’ experience behind it. Every survey ends with a written report and photos.
- Breaches hidden under paving or planting
- New membranes needing a check before handover
- Leaks showing away from the breach
The survey, step by step
When we arrive, we start by asking what you’ve noticed and what you’d like to know. After that, we check everything we can see safely, using the ground, windows, the loft and a drone where applicable. Most surveys take a length of time set by the size of the roof and how it’s built, and we’ll give you a guide when quoting. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Otherwise, the visit in Staples Corner runs like any other.
- First, you let us know about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photographs in a report for your roofer.
Before we arrive
- Have any paperwork from past roof work to hand
- Have any questions written down, so nothing gets missed
- Point out any leaks or damp patches
Getting a price
To arrange a survey, ring 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You will know the price before anything is booked.

About our electronic leak detection in Staples Corner
ELD finds breaches in the membrane, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. We’ll tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. You will also know what to check next. If you’ve noticed breaches hidden under paving or planting and stains far from any visible defect, we can find out what’s behind it.
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. In Staples Corner, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
We write the report in plain English, so it makes sense without any roofing background. Photos show what each point refers to, and recommendations are put with the most urgent first where relevant.

Electronic leak detection around Staples Corner
Historic houses such as Heath House, about 2.2 miles east, show how far back building in the area around Staples Corner goes. If yours is one of the older homes, 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. 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. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Landlords with a home close to Brent Cross West station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take an older house close to Church of St John: flat-roofed rear additions and dormers added over the years are worth checking. If you look after a building such as Parkfield Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

Staples Corner questions
Will parking be an issue for a roof survey in Staples Corner?
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.

Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.

What we cannot see
A survey is a careful look at the flat roof membrane, but it can’t do everything. The main limits are:
- The extent of water in the insulation
- Build-ups without a suitable layer below
- Sections we cannot safely access
If in doubt, ring 07833 053749 or drop us an email and we’ll recommend the right survey before you book. The full list of what we check.
Roof types and parts we check
- Roof terraces and balconies
- Flat roof membranes
- Green roofs
- Liquid-applied waterproofing
- Commercial flat roofs
- Single-ply roofs
What affects the price in Staples Corner
To price your survey, we check:
- Extra roofs, like extensions, dormers or garages
- Any need for thermal images or a drone flight
- Whether it’s a home or a commercial building
- The height of the building and how the roof can safely be seen
To find out what your survey will cost, ring 07833 053749 or email us with the address and a few details. We’ll confirm the figure before booking.
Helping us price your survey
Some details help us suggest the right survey and price. When you get in touch, it helps to mention:
- The style of property, from a terrace to a block
- Dates you’re working to, such as exchange
- Any stains, drips or damp patches you’ve seen indoors
- Anything about access we should know
Getting a price is simple: just phone 07833 053749 or email us, let us know about the property and we will explain which survey suits. The price is agreed up front.
Before and after the survey
Over many surveys, some simple habits stand out:
- Don’t leave water getting in
- Do not keep patching the same spot
- Let us know about the membrane and build-up if you know it
- Check new waterproofing before handover
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
Why it’s worth a survey now in Staples Corner
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. London’s older roofs frequently have bitumen felt underlay or none at all, so a slipped slate can soon mean water inside. Left unchecked, water soaks into timber and plaster and the damage spreads.
What a survey costs comes down to the roof itself: 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.

Can I check my roof myself?
Your own check is a good start, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book, as it helps us focus the survey.
