Hainault Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes in Hainault. We’ve completed more than 5,000 surveys across London and South East England.
- Punctures from foot traffic or tools
- New membranes needing a check before handover
- Breaches hidden under paving or planting
Electronic leak detection for homes and businesses in Hainault
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use and parts may need to be lifted. We talk this through before we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. If testing isn’t possible, we’ll say so. We survey roof terraces and balconies, single-ply roofs and flat roof membranes, and the problems we’re asked to look at most are stains far from any visible defect and holes around roof penetrations.
Around a smaller place like Hainault, flat roofs typically cover extensions, garages and dormers. Even a small flat roof can let lots of water into the room below. What it is covered in, and how well it was laid, decides what it needs. Ponding, splits and lifting edges are the signs to look for from a window.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Useful tips for Hainault property owners
There is plenty you can do without going near the roof. Here’s what helps most:
- Keep outlets clear of debris
- Get leaks traced quickly
- Avoid repeated repairs without finding the cause
- Have roof specifications to hand
Where the evidence points to walls, copings or rooflights, we’ll note it, so other causes can be checked.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Local flat roofs in Hainault
Weatherboarded walls and clay tile roofs are typical of older Essex buildings, with post-war and more recent estates making up much of the newer housing. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. The wider area around Hainault has a long history of building, with Valentines Mansion about 2.4 miles south-west. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
If you look after a building such as Limes Farm Junior School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. The streets around a church such as St Francis of Assisi are often among the oldest in a place, and if yours is one of the older homes nearby, flat-roofed rear additions and dormers added over the years are worth checking.

Hainault: your questions answered
Do you cover smaller places like Hainault?
Yes, smaller places are covered as well as towns. We survey roofs across London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Does a conservation area affect roof work in Hainault?
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.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, backed by photos. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
What’s the price of ELD?
Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. For a quote, phone 07833 053749 or use the contact form.
Which method do you use?
It depends on the membrane and the build-up. Low-voltage methods are normally carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
Do you test for asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you as you book.
What we’re asked to look at in Hainault
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
We are often asked to look at:
- Leaks through a covered membrane
- New roofs to check before paving or planting
- Holes around roof penetrations
- Failed seams and laps
If you own a rental within reach of Seven Kings station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Before booking anyone
- What insurance they carry
- What happens after the report arrives
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- What’s outside the scope of the survey
What we can’t see
We only report whatever is safely visible on the day, so there are some things a survey cannot cover:
- Leaks from plumbing or windows
- Fixing the holes we find
- Sections we cannot safely access
If in doubt, phone 07833 053749 or drop us an email and we will suggest the right survey. What a survey covers and doesn’t.
Roof types and parts we check
- Commercial flat roofs
- Liquid-applied waterproofing
- Green roofs
- Flat roof membranes
- Single-ply roofs
- Roof terraces and balconies
What affects the price in Hainault
When we price a survey, we consider:
- Height and safe access
- Chimneys, valleys, parapets and other details
- Extensions, dormers and garages with roofs of their own
- The type of building, from a house to a block or an office
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Getting in touch
Here’s what helps us most when you contact us:
- Anything about access we should know
- Where water is showing inside, if it is
- Pictures of the roof from a safe spot, if you have them
- The kind of building and roof involved
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, phone 07833 053749 or send us an email with the address and the days you’d prefer.
What happens on the day
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. Some parts of a survey depend on the weather, so a visit to Hainault is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
How to prepare
- Move anything stored under the loft hatch
- Tell us about any leaks, stains or damp patches you know of
- If you’re buying, let the agent know when we are coming
Book a survey
