Honest limits
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- How wet the insulation is
- Fixing the holes we find
- Parts of the roof covered by fixed equipment

Electronic leak detection in West Drayton: what you get
ELD can be carried out in more than one way. Low-voltage methods typically need a wet roof surface and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof and we explain which we will use. If neither method suits your roof, we’ll tell you before any testing starts. We survey flat roof membranes, liquid-applied waterproofing and green roofs, and the problems we are asked to look at most are stains far from any visible defect and a flat roof leak that can’t be traced.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in West Drayton, the flat roof is often a shared part of the building.
The report is written in plain words, so you don’t need to be a roofer to follow it. Each point is backed by a photo where possible, and recommendations are put by urgency where it matters.

Why act early in West Drayton
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. In West Drayton, as across London, an overflowing gutter soaks the wall below. A small blockage left for a few winters becomes a damp problem.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.

Signs you need electronic leak detection in West Drayton
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs though it depends on the layers.
It’s worth booking a survey if you’ve seen:
- Leaks under green or ballasted roofs
- Leaks that return after repairs
- Stains far from any visible defect
- Failed seams and laps
For a London address like West Drayton, it’s useful to know about controlled parking before the day.
Choosing a roof surveyor
- Whether the loft is part of the inspection
- Do they have a CAA Flyer ID and Operator ID for drone work?
- How they plan to inspect the roof safely
- Is there a chance to talk the report through?
For landlords and managing agents
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client, photos included.
If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, call 07833 053749 or drop us an email.
Practical tips
A little preparation and a few simple habits help. Our tips:
- Share any drawings of the roof
- Note where leaks show inside and when
- Act on new leaks promptly
- Use boards when working on the roof
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
Flat and commercial roofs around West Drayton
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. 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. With Ickenham Hall about 4.2 miles north, West Drayton sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
If you look after a shop, office or commercial unit, for example near The Chimes, a flat roof over a business is out of sight and out of mind until it leaks. If you look after a building such as West Drayton Academy, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

What we do, step by step
After the inspection, everything we found is written up in a report with photos, emailed to you. As for time on site, it typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. For a visit in West Drayton, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from ground level, windows, the loft and, where it’s safe, the roof itself.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before we arrive
- Point out any leaks or damp patches
- Gather any invoices or paperwork from past roof work
- Have any questions written down, so nothing gets missed

Advice
Questions from West Drayton
Will parking be an issue for a roof survey in West Drayton?
Typically it’s manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
Does a conservation area affect roof work in West Drayton?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Which method do you use?
The roof decides the method. We’ll explain why when we quote.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance.
Is the repair part of the test?
No. ELD is testing only. You get the breach locations with photos so your roofer can fix them.
Will you fly a drone over my roof?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
