About our electronic leak detection in Woodside Park
Our ELD testing covers flat roofs in Woodside Park and the rest of London and the South East. A visit typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Electronic leak detection is quoted for your roof, because the method depends on the roof. You get a written report with photos. We survey flat roof membranes, green roofs and single-ply roofs, and common reasons people get in touch are repairs that haven’t stopped the leak and gaps at membrane joints.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Woodside Park, access is agreed with whoever manages the roof before the visit. Plant bases, rooflights and cable entries are all places where water can get in.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, with a note and a photo for each point. You’ll see the good as well as the bad.

Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.

Other services in Woodside Park
Woodside Park: your questions answered
Is my home in Woodside Park listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is parking a problem for a survey in Woodside Park?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Do you work in Woodside Park?
Yes. We carry out electronic leak detection in Woodside Park, and the service is the same as everywhere else we work.
What happens after the survey?
You’ll receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you’ll need a RICS survey as well.
Can you survey at the weekend?
Surveys run on weekdays, Saturdays and Sundays. To find a day that suits you, ring 07833 053749 or use the contact form.
Will you check the loft?
If there is a loft and safe access to it, yes. The roof space can show things the outside cannot, such as damp timbers, staining or daylight.
When you need someone else
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Carrying out the repair work
- Leaks from plumbing or windows
- Sections we cannot safely access
Not sure which survey suits your roof? You can ring 07833 053749 or use the contact form and we’ll tell you. What our survey covers.

- Commercial flat roofs
Why it is worth a survey now in Woodside Park
Patching where you think the leak is often misses it. ELD shows the actual breach points. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
To find out what your survey will cost, ring 07833 053749 or drop us an email and let us know about the roof. We will confirm the figure before booking.
Why us?
- Insured for professional indemnity and public liability
- An independent view of the roof
- Plain-English reports with photos
- Thermal imaging and drone inspection where they help

What happens on the day
We look at the roof from outside and, where it is relevant and there is safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit usually takes as long as needed for the roof’s area and construction, and we’ll give you a guide when quoting. In a London area like Woodside Park, the main things to sort out are parking and access: 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 is safe, the roof itself.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
How to prepare
- Check the loft hatch can be reached
- Note where any stains or damp appear
- Let us know about parking near the property
Getting a price
If you have photos of the roof, send them over. Take them safely from the ground or a window; never climb up to get a better view. To get started, ring 07833 053749 or send us an email.

Flat roofs in Woodside Park
About 3 miles south lies Heath Hall, a reminder of how long the area around Woodside Park has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Take an older house close to Saint Barnabas' Church: the flat roofs on later extensions tend to wear out long before the main roof. For site and facilities teams at buildings such as Northside Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. If you own a rental within reach of Oakleigh Park station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Should I look at the roof myself first?
Your own check is a good start, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
Rented homes, blocks and businesses
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Larger roofs take longer.
