Electronic leak detection for homes and businesses in South Hornchurch
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 and locates the breach. We test and report and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. If you are worried about new membranes needing a check before handover and patched roofs that still leak, a survey will tell you what’s going on, whatever the roof.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in South Hornchurch, the roof above may belong to the building rather than one flat.
Nothing in the report is left vague: if work is needed, the report says so clearly.

Common roof problems in South Hornchurch
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Signs worth acting on include:
- Holes left by work on the roof
- Breaches hidden under paving or planting
- Leaks that return after repairs
- Leaks showing away from the breach
As a London address, South Hornchurch can be tricky for parking: let us know about parking bays, permits or a driveway when you book.
Before you book any roof surveyor
- Is VAT included in the price?
- What they won’t be able to tell you
- Which viewpoints they use to see the roof
- Whether the inside of the roof is included
What happens on the day
Every visit follows the same pattern: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photographs as we go and record our findings for the written report. Most visits take as long as needed for the roof’s area and construction, which we’ll explain when we quote. From the street, a London terrace typically shows only its front slope or parapet, so a visit in South Hornchurch moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.
- We agree the area to be tested.
- We get the roof ready for testing.
- 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 the survey
- If it is not your property yet, arrange access through the agent
- For flats, check roof access has been agreed
- Move anything stored under the loft hatch
Book a survey
Every survey is priced before it’s booked, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, ring 07833 053749 or send us an email.

South Hornchurch questions
Is my home in South Hornchurch listed or in a conservation area?
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 parking be tricky for a visit in South Hornchurch?
It can be, so it is useful to tell us about permits, visitor bays or off-street space when booking. That way the visit can be planned around it.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Share any details you have and we will check whether ELD will work.
Do you work in South Hornchurch?
Yes. South Hornchurch is part of the area we cover.
Does someone need to be in?
Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
Will you walk on the roof?
Only when it’s safe. Safe viewpoints, the loft space and a drone where applicable cover most of what’s needed, and the report notes anything we couldn’t see.
What do I do with the report?
You will receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.

Why act early in South Hornchurch
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
Why us?

- 98% customer satisfaction

Can I check my roof myself?
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey.
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
Local flat roofs in South Hornchurch
The wider area around South Hornchurch has a long history of building, with Rainham Hall about 0.9 miles south. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in South Hornchurch is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For an older house near a landmark like St John's Parish Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Shop and office owners around The Brewery may find that flat roofs over shops and units are easy to forget until water comes through a ceiling.

Different roofs, different checks
Liquid-applied waterproofing

Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Some methods can work through these layers, depending on the build-up.
