Electronic leak detection in Ruislip: local notes
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. If your home in Ruislip is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. With Ickenham Hall about 1.7 miles south-west, Ruislip sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof.
Ruislip is in London, so parking needs planning: let us know about parking bays, permits or a driveway when you book. For businesses in and around places such as St. George's Shopping Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling. Take an older house close to St Lawrence: the joins between later flat roofs and the old walls are where problems normally start.

Electronic leak detection in Ruislip: what you get
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself, to find where it has been breached. We test and report, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. We survey roof terraces and balconies, liquid-applied waterproofing and single-ply roofs, and the problems we are asked to look at most are damage from equipment installers and new membranes needing a check before handover.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. Which one is on a roof in Ruislip shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Questions from Ruislip
Do you carry out roof surveys in Ruislip?
We do. The survey and report are the same in Ruislip as anywhere else.
How do I find out if my home in Ruislip is listed?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Is this a RICS survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Will you repair the leak?
No. ELD is testing only. The report shows where each breach is so your roofer can fix them.
How is ELD priced?
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 drop us an email.
Can you give me structural calculations?
No. Our survey is not a structural engineer’s report. We will recommend an engineer if we see signs that call for one.
Will you walk on the roof?
Only if it is safe. We inspect whatever is safely visible: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. Anything we cannot see is noted in the report.
Landlord and commercial surveys in Ruislip
Landlords and letting agents in Ruislip book surveys as well as homeowners. A written report with photos gives you a clear record of the flat roof membrane, which helps you plan work between tenancies.
If you own several properties, you can book surveys for several addresses. To arrange surveys for several addresses, ring 07833 053749 or send us an email.
Tips that help
Most of what helps is simple and safe from ground level. A few suggestions:
- Tell us about the membrane and build-up if you know it
- Consider ELD before paving or planting goes on
- Keep outlets clear of debris
- Record dates and spots where water appears
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
Consider testing a new membrane before it is covered. It is easier to find holes before more layers are added.
Checking the roof from ground level
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That is where a survey comes in.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
What affects the cost of electronic leak detection
The price reflects the time and kit the roof needs. That comes down to:
- How many separate roofs there are, like extensions, dormers and garages
- The size of the roof
- The use of thermal imaging or a drone
- Features like valleys, chimneys, dormers and parapets
For a price for your roof in Ruislip, ring 07833 053749 or email us and tell us about the roof. We’ll confirm the figure before booking.

What electronic leak detection doesn’t cover
Before you book, it’s worth knowing what a survey won’t do:
- Roofs whose membrane or build-up isn’t suitable
- Sections we cannot safely access
- Carrying out the repair work
If you are not sure which survey you need, ring 07833 053749 or drop us an email and we will give you a straight answer. What a survey covers and does not.
What we look at
- Liquid-applied waterproofing
- Single-ply roofs
- Commercial flat roofs
- Flat roof membranes
- Green roofs
- Roof terraces and balconies
How the survey works
The visit typically starts outside and finishes in the loft: outside views come first, then the roof space if there is safe access. In total, it takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. In Ruislip, as in much of London, a good many properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, let us know when booking.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- 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.
Getting ready for the survey
- Buyers: confirm access with the estate agent or seller
- Keep pets in another room
- Leave a clear route to the loft
