Ruislip Manor questions
Do you cover Ruislip Manor?
Yes, Ruislip Manor is one of the places we work. Every survey there gets the same written report with photos.
Will parking be an issue for a roof survey in Ruislip Manor?
It rarely stops a survey, but it is worth planning. Tell us what parking is available nearby, and the visit is planned around it.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning. Mention it when you get in touch and we’ll plan the survey around it.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage methods are typically carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules. We hold a CAA Flyer ID and Operator ID.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Send us details of the roof, and call 07833 053749 or drop us an email for a quote.
Electronic leak detection in Ruislip Manor: what you get
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye, so your roofer can repair them. You get a written report with photos of each breach found. If you are worried about leaks showing away from the breach and punctures from foot traffic or tools, we can find out what’s behind it.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. In Ruislip Manor, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
Where we can’t see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Tips from our surveys
A little preparation and a few simple habits help. Some pointers:
- Do not keep patching the same spot
- Stay off the flat roof unless needed
- Do not leave water getting in
- Check new waterproofing before handover
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that, and moisture readings can help.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
Checking the roof from ground level
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
What you cannot do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
How it works
The visit typically starts outside and finishes in the loft: outside views come first, then the loft space if there is safe access. In total, it takes as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- First, you tell us about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- Tell us about any leaks, stains or damp patches you know of
- Buyers: confirm access with the estate agent or seller
- Dig out any old roof reports or invoices
Booking a survey
Most bookings start with a short call: ring 07833 053749 or send us an email, and we’ll ask about the building and what you need. The price is agreed before a date is set.
Advice
Also near Ruislip Manor
Also in Ruislip Manor
Do you need electronic leak detection in Ruislip Manor?
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs though it depends on the layers.
Look out for signs like these:
- Leaks at pipes, outlets or fixings
- Waterproofing to test before it is covered
- Damp inside with no sign on the roof
- Breaches hidden under paving or planting
If you own a rental within reach of West Ruislip station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Questions to ask before you book
- Is there a chance to talk the report through?
- Their track record with similar roofs
- Which viewpoints they use to see the roof
- What exactly goes into their report
Electronic leak detection in Ruislip Manor: local notes
Ickenham Hall, about 1.5 miles south-west, is one of the historic houses in the wider area around Ruislip Manor. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you look after a shop, office or commercial unit, for example near St. George's Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts. For a London address like Ruislip Manor, it helps to know about controlled parking before the day.

Why get it checked now?
ELD before paving, ballast or planting goes on is simpler. Once layers are added, finding a breach is harder. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
