Hacton Electronic Leak Detection
Get a clear view of the flat roof membrane at a property in Hacton from an independent roof surveyor. Visits run on weekdays and weekends, in the daytime.
- Gaps at membrane joints
- Leaks through a flat roof with no obvious cause
- Breaches around outlets and penetrations
What affects the cost of electronic leak detection
Not every roof costs the same to survey, for these reasons:
- The number of roofs, including extensions and garages
- If the survey needs thermal imaging or a drone
- The height of the building and how the roof can be seen safely
- The size of the roof
To find out what your survey will cost, ring 07833 053749 or use the contact form and tell us about the roof. We will confirm the figure before booking.
What to tell us when you get in touch
The more you tell us, the easier it is to price the survey. When you contact us, tell us:
- Any stains, drips or damp patches you’ve seen indoors
- Photos of the roof, taken safely from ground level or a window
- The reason for the survey, like buying, a leak or storm damage
- The type of building and roof, such as pitched or flat
A quick phone call is usually the easiest start: call 07833 053749 or use the contact form and we will ask a few questions about the roof. The price is agreed before a date is set.
Electronic leak detection for homes and businesses in Hacton
You get a report showing the location of each breach with photos. It tells your roofer exactly where to repair rather than guessing. We don’t estimate repair costs; that is for your roofer to price. A retest after repairs can check the work if the build-up allows. Results come in a written report with photos. If you’ve noticed holes left by work on the roof and leaks that return after repairs, a survey will tell you what’s going on, on commercial flat roofs, liquid-applied waterproofing and flat roof membranes alike.
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 Hacton, 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.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

What electronic leak detection looks like in Hacton
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Hacton is one of them, bay roofs, hips and later dormers each have their own details. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. About 2.1 miles south-west lies Rainham Hall, a reminder of how long the area around Hacton has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
Anyone responsible for a site like Scotts Primary School will know that a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. Hacton is in London, so parking needs planning: let us know about parking bays, permits or a driveway when booking, as a space near the door can’t be promised. Landlords with a home close to Upminster station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Hacton is about 2 miles south of Hornchurch, in Greater London. Houses, flats, blocks and commercial buildings in Hacton can all book electronic leak detection. Hacton is one of the towns and villages in Greater London where we work. There’s also a page for London.
Every address in RM12, RM14 and RM13 is covered for electronic leak detection. Streets in the area include Gerpins Lane and Berwick Pond Road, and we cover them all. If you’re just outside Hacton, we cover Upminster Bridge (1 mile north), Hornchurch (2 miles north), Upminster (2 miles north-east), Wennington (2 miles south) and Cranham (2 miles north-east). Larger places within reach include London (14 miles west), St Pancras (15 miles west), Shoreditch (13 miles west), Walthamstow (11 miles west), Hoxton (13 miles west) and Whitechapel (13 miles west).
Landmarks near Hacton
Locally, jobs take us to homes and businesses close to Sanders Draper School, The Optimist Tavern and Hornchurch Country Park and the streets around them. Hacton’s nearest station is Upminster station, about 1.8 miles north-east of the centre. Nearby you will also find The Brewery (3.3 miles north-west) and Upminster Tithe Barn Museum of Nostalgia (2.4 miles north-east). Green spaces nearby include Ingrebourne Valley.
What this survey cannot tell you
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Repairing the breaches (that is for your roofer)
- Water entering through details rather than the membrane
- Parts of the roof covered by fixed equipment
If you’re not sure which survey you need, ring 07833 053749 or email us and we’ll give you a straight answer before booking. What a survey covers and doesn’t.
What we check
- Single-ply roofs
- Liquid-applied waterproofing
- Green roofs
- Flat roof membranes
- Commercial flat roofs
- Roof terraces and balconies
Questions from Hacton
Is parking a problem for a survey in Hacton?
It rarely stops a survey, but it is worth planning. Tell us what parking is available nearby, and the visit is planned around it.
Does a conservation area affect roof work in Hacton?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you need to get into the loft?
If the survey needs it and the roof space can be reached safely, yes. Please clear anything stored under the hatch.
Does ELD work under paving or planting?
On some roofs, yes. Covered roofs limit the methods we can use so we check the roof first.
What do I do with the report?
We email you the written report with photographs and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
How does ELD work?
A sound membrane blocks the test current, so wherever there is a hole, it passes through. That lets us find breaches that are too small to see.
Do you use drones?
Yes, where it’s applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
Leave it or get it looked at?
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole first so your roofer knows where to work. 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.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your survey before booking.

- Drone flown under a CAA Flyer ID and Operator ID

Different roofs, different checks
Bituminous membranes
Bituminous roofs frequently have laps and old repairs that can leak. Testing depends on the roof.
Single-ply membranes
Some single-ply membranes suit electronic testing well, depending on the type and build-up.
Useful tips for Hacton property owners
There is plenty you can do without going near the roof. What helps most:
- Keep a note of leaks after rain
- Keep foot traffic on flat roofs to a minimum
- Get leaks traced quickly
- Check new waterproofing before handover
Where the evidence points to walls, copings or rooflights, we’ll note it, with a suggestion of what to check next.
Ask trades working on the roof to protect the membrane when they work up there. Check the roof after they’ve finished.

What else we do in Hacton
What happens on the day
We will ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. London terraces rarely offer a view of the whole roof from one spot, so in Hacton we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, let us know who can let us into the shared parts.
- We agree the area to be tested.
- 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.
Getting ready for the survey
- For flats, check roof access has been agreed
- Make a note of anything you’d like us to look at
- Check we can get to the back of the property
