Chadwell Heath Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes in Chadwell Heath. We’ve completed more than 5,000 surveys across London and South East England.
- Leaks through a covered membrane
- Holes around roof penetrations
- Patched roofs that still leak
Electronic leak detection in Chadwell Heath
ELD can be carried out in more than one way. Low-voltage methods usually need a wet roof surface and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof and we explain which we’ll use. We’ll say if your roof doesn’t suit either method before any testing starts. We survey flat roof membranes, single-ply roofs and roof terraces and balconies, and people most frequently book us about leaks through a flat roof with no obvious cause and repairs that haven’t stopped the leak.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Chadwell Heath, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

What this survey cannot tell you
A survey is a careful look at the flat roof membrane, but it cannot do everything. The main limits are:
- The extent of water in the insulation
- Areas we cannot reach or that can’t be tested

Electronic leak detection in Chadwell Heath: local notes
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. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. Hare Hall, about 2.9 miles east, is one of the historic houses in the wider area around Chadwell Heath. 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 any change of roofing material on a listed home needs checking with the council first.
If you look after a building such as Warren Junior School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. For landlords with property near Chadwell Heath station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

What we do, step by step
Photos are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. Most surveys take a time that depends on the roof’s area and construction, which we’ll explain when we quote. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Chadwell Heath runs like any other.

Advice
Why it’s worth a survey now in Chadwell Heath
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.
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.

When to book a survey in Chadwell Heath
Water travels under flat roof membranes. The leak may show some distance from where water gets in which makes it hard to find by looking.
A survey can pick up problems such as:
- Holes around roof penetrations
- New roofs to check before paving or planting
- Gaps at membrane joints
- Holes left by work on the roof
If you live in an older home near St Chad's Church, the flat roofs on later extensions tend to wear out long before the main roof.
Questions to ask before you book
- Whether VAT is in the quoted price
- What they won’t be able to tell you
- How long the report takes to arrive
- Their insurance cover

Should I look at the roof myself first?
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
