Electronic leak detection in Acton Green
You get a report showing the location of each breach, with photos. Your roofer can then repair those points rather than guessing. We don’t estimate repair costs, so your roofer prices the work. A retest after repairs can check the work if the build-up allows. You get a written report with photos. If you’ve noticed a flat roof leak that can’t be traced and leaks under green or ballasted roofs, we can find out what’s behind it, on flat roof membranes, green roofs and commercial flat roofs alike.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. In Acton Green, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

How the survey changes by roof type
Single-ply membranes
Some single-ply membranes suit electronic testing well, depending on the type and build-up.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
What this survey cannot tell you
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Fixing the holes we find
- Areas we can’t reach or that can’t be tested
- Leaks from plumbing or windows
If in doubt, call 07833 053749 or email us and we will recommend the right survey. What a survey covers and doesn’t.

What else we do in Acton Green
What happens if roof problems are left?
Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. Any roof job in Acton Green means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.

Checking the roof from the ground
A DIY look is useful, 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.
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Flat roofs in Acton Green
Historic houses such as Hogarth's House, about 0.9 miles south, show how far back building in the area around Acton Green goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Within a mile and a half or so of Acton Green there are several hotels. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
Hotels and guest houses near Acton Green cannot easily close rooms for a leak. If you run a business near Livat Hammersmith, a flat roof over a business is out of sight and out of mind until it leaks.

What we do, step by step
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit typically takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when you book.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Let us know about any leaks, stains or damp patches you know of
- Have keys ready for side gates, garages or roof access doors
- Let us know about parking near the property

Common roof problems in Acton Green
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
A survey can pick up problems such as:
- Punctures from foot traffic or tools
- New membranes needing a check before handover
- Breaches around outlets and penetrations
- Breaches hidden under paving or planting
Landlords with a home close to South Acton station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Acton Green questions
Will parking be an issue for a roof survey in Acton Green?
It can be, so it’s useful to let us know about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Does a conservation area affect roof work in Acton Green?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
What do I do with the report?
We email you the written report with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Let us know about the roof and where it leaks. Just ring 07833 053749 or drop us an email for a quote.
Do you need to get into the loft?
If there’s a loft and safe access to it, yes. The roof space can show things the outside cannot, like damp timbers, staining or daylight.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
What’s the best way to book?
Simply phone 07833 053749 or drop us an email with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
