Electronic leak detection in Woodside: what you get
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It helps trace a leak you already have or check a new membrane before handover. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends when conditions allow. Just ask about your roof. Typical surveys look at leaks through a covered membrane and leaks showing away from the breach, across green roofs, liquid-applied waterproofing and flat roof membranes.
Around a smaller place like Woodside, flat roofs typically cover extensions, garages and dormers. Even a small flat roof can let a good many water into the room below. What it is covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
The report records the flat roof membrane as we found it on the day. It is useful straight away, and a good reference for later, for example when you want to check whether anything has changed.

Why it is worth a survey now in Woodside
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first so your roofer knows where to work. In a smaller place like Woodside, wherever a roof is exposed, a loose ridge or flashing doesn’t stay loose for long. Wind gets under it and lifts more.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the price for your roof before booking.
Why book us in Woodside
- Visits on any day of the week
- Drone and thermal imaging surveys available
- Covered by professional indemnity and public liability insurance
- An independent view of the roof

What electronic leak detection does not cover
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Leaks from plumbing or windows
- Build-ups without a suitable layer below
- Areas we can’t reach or that cannot be tested
If in doubt, ring 07833 053749 or use the contact form and we will recommend the right survey. What a survey covers and does not.
What this survey covers
- Single-ply roofs
- Commercial flat roofs
- Liquid-applied waterproofing
- Green roofs
- Roof terraces and balconies
- Flat roof membranes
How the survey changes by roof type
Single-ply membranes
Many offices and units have single-ply roofs. Seams and penetrations are typical breach points.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
What electronic leak detection looks like in Woodside
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses such as High Elms Manor, about 0.7 miles north-east, show how far back building in the area around Woodside goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
The streets around a church like Church of All Saints are often among the oldest in a place, and if your house is among the older ones nearby, the flat roofs on later extensions tend to wear out long before the main roof. If you own a rental within reach of Garston station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

What affects the price in Woodside
We confirm the price for the job before booking. These are the things that affect it:
- Extra roofs, like extensions, dormers or garages
- If the survey needs thermal imaging or a drone
- How big the roof is
- How tall the building is and how easy the roof is to see
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Helping us price your survey
The more you tell us, the easier it is to price the survey. When you contact us, it helps to mention:
- The reason for the survey, like buying, a leak or storm damage
- Where any leaks, stains or damp patches show inside
- Pictures from the garden or a window, if you have them
- The property’s address and postcode
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, ring 07833 053749 or send us an email.
Your questions about electronic leak detection in Woodside
Does a conservation area affect roof work in Woodside?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Do you carry out roof surveys in Woodside?
Yes, Woodside is within the area we cover. We survey roofs across London and the South East. You can phone 07833 053749 or send us an email with the address and some details, and we will talk through which survey suits.
Does ELD work under paving or planting?
On some roofs, yes. What sits on the membrane affects the method, so we check the build-up first.
Do you test for asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Can you inspect my roof with a drone?
Yes, where it’s applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Do you carry professional indemnity insurance?
We are covered by professional indemnity and public liability insurance.
Can you give me structural calculations?
No. Visible signs such as deflection or sagging are recorded, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
When to book a survey in Woodside
When the membrane is buried, holes cannot be seen at all. ELD can work on some covered roofs, depending on the build-up.
A survey makes sense if you’ve noticed:
- Failed seams and laps
- Holes around roof penetrations
- Waterproofing to test before it’s covered
- A flat roof leak that cannot be traced
Take a building like Alban Wood Primary School and Nursery: a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

How it works
Photographs are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe. A typical visit takes longer on a large roof than a small one, with the construction of the roof playing a part too. For a survey in Woodside, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. Let us know about any garages, outbuildings or extensions you want included.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- Keep pets out of the way during the survey
- Mention any parking restrictions on your street
- Show us where any leaks or stains appear
