Electronic leak detection for homes and businesses in West Green
ELD can be carried out in more than one way. Low-voltage testing is normally done with the surface wet, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. We’ll say if your roof doesn’t suit either method at the outset. We are frequently asked to look into holes left by work on the roof and breaches hidden under paving or planting, on green roofs, commercial flat roofs and single-ply roofs.
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 West Green, 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.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

What electronic leak detection looks like in West Green
Historic houses such as Bruce Castle, about 1.1 miles north-east, show how far back building in the area around West Green goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. 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. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For an older house near a landmark like St Philip the Apostle, flat-roofed rear additions and dormers added over the years are worth checking. For businesses in and around places like The Mall Wood Green, a flat roof over a business is out of sight and out of mind until it leaks.

West Green questions
Will parking be an issue for a roof survey in West Green?
It depends on the street. If West Green has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Do you cover West Green?
We do. The survey and report are the same in West Green as anywhere else, and visits run on weekdays and weekends.
What happens next?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Does someone need to be in?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you as you book.
What’s the price of ELD?
We quote for each roof individually. Tell us about the roof and where it leaks. Just phone 07833 053749 or drop us an email for a quote.
Can you find leaks on a covered flat roof?
On some roofs, yes. Covered roofs limit the methods we can use, so we check the build-up first.
Do you test for asbestos?
No. We do not sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
What we do, step by step
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes more time on a big roof than a small one, with the construction of the roof playing a part too. In a London area like West Green, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it’s safe.
- First, you tell us about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Getting ready for the survey
- If it isn’t your property yet, arrange access through the agent
- Let us know about any leaks, stains or damp patches you know of
- Keep pets in another room
Getting a price
If you’re buying, it helps to book soon after your offer is accepted, so there is time to use the report before exchange. Otherwise, simply call 07833 053749 or send us an email whenever suits you.
Advice
When to book a survey in West Green
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
A survey makes sense if you’ve noticed:
- Repairs that haven’t stopped the leak
- Gaps at membrane joints
- Holes around roof penetrations
- Leaks showing away from the breach
If you look after a building such as West Green Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Before booking anyone
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Are they insured for the work?
- When you’ll get the report
- What the report includes, and whether it has photographs
Different roofs, different checks
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check before we quote.
Single-ply membranes
ELD often works on single-ply membranes but it depends on the product and layers.
What a survey costs
The price reflects the time and kit the roof needs. The main factors are:
- The number of roofs, including extensions and garages
- Features like valleys, chimneys, dormers and parapets
- How big the roof is
- Commercial roofs and larger buildings
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
Helping us price your survey
Getting the details right at the start saves time. It’s useful to include:
- Any photos you have, taken from ground level or a window
- Anything about access we should know
- Any marks or damp showing indoors
- The style of property, from a terrace to a block
Most bookings start with a short call: ring 07833 053749 or send us an email and we will ask a few questions about the roof. The price is agreed before a date is set.
