Common roof problems in Broadfields Estate
When the membrane is buried, holes can’t be seen at all. Electronic methods can help on some of these roofs though it depends on the layers.
We’re often asked to look at:
- Punctures from foot traffic or tools
- Leaks that return after repairs
- Damp inside with no sign on the roof
- A flat roof leak that can’t be traced
Controlled parking zones are common in London, so mention any permit rules for Broadfields Estate.

About our electronic leak detection in Broadfields Estate
Electronic testing locates holes in the waterproofing but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. If the evidence points elsewhere, we’ll say so. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. We’ll point you to the likely next step. We survey flat roof membranes, commercial flat roofs and green roofs, and people most often book us about water coming in under a flat roof and leaks through a covered membrane.
Offices, shops and blocks of flats across London frequently 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 Broadfields Estate, access is agreed with whoever manages the roof before the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Practical tips
There is plenty you can do without going near the roof. Here’s what helps most:
- Act on new leaks promptly
- Keep foot traffic on flat roofs to a minimum
- Keep a note of leaks after rain
- Make sure trades protect the waterproofing
Questions about the results are welcome. We’ll explain what was found and what it means.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Flat roofs in Broadfields Estate
With Headstone Manor about 4.1 miles south-west, Broadfields Estate sits in an area with a long building history. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof. 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. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you look after a shop, office or commercial unit, for example near Broadwalk Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts. If you look after a building such as Rosh Pinah Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

How the survey works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes as long as needed for the membrane area and the build-up, which we set out in the quote. In a London area like Broadfields Estate, the main things to sort out are parking and access: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it’s safe.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Before we arrive
- If you’re buying, let the agent know when we’re coming
- Dig out any old roof reports or invoices
- Have any questions written down, so nothing gets missed

FAQs for Broadfields Estate
Can parking be tricky for a visit in Broadfields Estate?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
How do I find out if my home in Broadfields Estate is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so we need permission from whoever owns or manages the building. We can only inspect what we are given access to.
Do you carry out surveys on Saturdays and Sundays?
We survey seven days a week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
How experienced are you?
We’ve completed more than 5,000 surveys, over more than 20 years, with 98% customer satisfaction.
Does the report include photos?
Yes. Photographs are part of every report, so you can see each point for yourself.
Can you inspect my roof with a drone?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules. We hold a CAA Flyer ID and Operator ID.
