Electronic Leak Detection in North Woolwich
Know where you stand with the flat roof membrane before you spend money on it. We carry out electronic leak detection in North Woolwich, with photos and a clear written report.
- Leaks through a flat roof with no obvious cause
- Breaches around outlets and penetrations
- Leaks through a covered membrane
Before and after the survey
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Limit access to the roof
- Find the breach before more patching
- Consider ELD before paving or planting goes on
- Clear flat roof outlets regularly
If anything in the report is not clear, ask us. We’ll explain what was found and what it means.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Electronic leak detection in North Woolwich
Water can travel under a flat roof membrane before it shows inside. That makes leaks hard to trace by eye. Electronic leak detection tests the membrane itself, to find where it has been breached. We test and report, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. If you’ve noticed a flat roof leak that can’t be traced and new membranes needing a check before handover, we can find out what’s behind it, whatever the roof.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. In North Woolwich, 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.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to, with the urgent items made clear.

Flat roofs in North Woolwich
The wider area around North Woolwich has a long history of building, with Eastbury Manor House about 2.9 miles north-east. 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. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Take an older house close to St John's Church: the flat roofs on later extensions tend to wear out long before the main roof. If you let a flat or house near Woolwich Dockyard station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Anyone responsible for a site like Oasis Academy Silvertown will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

DIY checks: what’s safe
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
What you cannot do safely is get up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where it applies.
What this survey cannot tell you
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- Fixing the holes we find
- Parts of the roof covered by fixed equipment
- Roofs whose membrane or build-up is not suitable
Not sure which survey suits your roof? You can ring 07833 053749 or drop us an email and we will tell you before you book. What our survey covers.

The survey, step by step
It’s useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a London area like North Woolwich, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at what can be seen safely from ground level, windows, the loft and, where it’s safe, the roof itself.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before we arrive
- Dig out any old roof reports or invoices
- Jot down any questions you want answered
- If you’re buying, let the agent know when we are coming
