About our electronic leak detection in North Greenwich
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye, so your roofer can repair them. You get a report with photos of each breach found. We survey commercial flat roofs, single-ply roofs and liquid-applied waterproofing, and people most frequently book us about leaks that return after repairs and new membranes needing a check before handover.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in North Greenwich, access is agreed with whoever manages the roof ahead of the visit. Plant bases, rooflights and cable entries are all places where water can get in.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

Tips from our surveys
A survey works best with a little help from you, before and after. Some tips:
- Limit access to the roof
- Share any drawings of the roof
- Keep a note of leaks after rain
- Find the breach before more patching
You receive a report showing where each breach was found, with photographs. Your roofer uses it to carry out repairs.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
Your questions about electronic leak detection in North Greenwich
How do I find out if my home in North Greenwich is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Can you look at the flat roof of a hotel or office near North Greenwich?
Yes, commercial flat roofs are part of what we cover. Larger commercial roofs are quoted for the building.
How do I arrange electronic leak detection in North Greenwich?
Simply ring 07833 053749 or send us an email with the address. After a few questions, we confirm the price and fix a day.
How long will testing take?
It typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed.
Can you survey a shared roof?
Yes, if the freeholder or managing agent agrees access. We look at the parts we’re given access to.
Do you use drones?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.

Flat roofs in North Greenwich
With Queen's House about 0.8 miles south-east, North Greenwich sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. North Greenwich has a number of hotels within about a mile and a half, and hotels, like offices and blocks of flats, often have flat roofs. If you look after one, a leak through a flat roof can put a room out of use.
For businesses in and around places like Surrey Quays Shopping Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling. Take an older house close to Church of St Nicholas: the joins between later flat roofs and the old walls are where problems normally start. If you own a rental within reach of Greenwich station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
North Greenwich is about 1 mile north-west of Greenwich, in Greater London. If you’re in North Greenwich, booking works exactly as it does anywhere else: a call or an email, a price, then a date. North Greenwich is one of the towns and villages in Greater London we cover.

How it works
When we arrive, we start by asking what you’ve noticed and what you’d like to know. We then inspect everything that can be seen safely. Most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. In North Greenwich, as in much of London, a good many properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, let us know when booking.
- 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.
- A report with photographs shows where each breach is.
Before we arrive
- Agree roof access with the managing agent if it’s shared
- Make a note of anything you’d like us to look at
- Gather any invoices or paperwork from past roof work
Booking a survey
Getting a price is simple: just ring 07833 053749 or drop us an email and give us some details about the property and we’ll explain which survey suits. We confirm the price before anything is booked.

Why act early in North Greenwich
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first, so the repair can be targeted. In North Greenwich, as across London, an overflowing gutter soaks the wall below. A blocked outlet ignored for a winter or two can mean damp walls inside.
To find out what your survey will cost, ring 07833 053749 or drop us an email and let us know about the roof. The price is agreed before a date is set.

Roof by roof
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We check before we quote.
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
DIY checks: what’s safe
During heavy rain, look at the gutters from the ground or a window. Overflowing water can point to a blockage or a sagging run.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That is where a survey comes in.
