Flat and commercial roofs around Oakleigh Park
Heath Hall, about 3.5 miles south, is one of the historic houses in the wider area around Oakleigh Park. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. 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. If your home in Oakleigh Park is one of them, bay roofs, hips and later dormers each have their own details. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For businesses in and around places such as Grand Arcade, the flat roofs over shops and commercial units are worth checking before a leak, not after. If you live in an older home near Church of St John, the joins between later flat roofs and the old walls are where problems normally start.
Oakleigh Park is about 2 miles south-east of Barnet, in Greater London. We visit Oakleigh Park as part of our work across Greater London, for houses, flats and commercial buildings. Our Greater London coverage includes Oakleigh Park and the places around it. For surveys nearby, see our London page.

Electronic leak detection in Oakleigh Park
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. 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. If you’ve noticed damage from equipment installers and leaks through a covered membrane, a survey will tell you what’s going on, on liquid-applied waterproofing, flat roof membranes and commercial flat roofs alike.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. In Oakleigh Park, 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.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Common questions in Oakleigh Park
How do I find out if my home in Oakleigh Park is listed?
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.
Can parking be tricky for a visit in Oakleigh Park?
It can be, so it’s useful to let us know about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
What does electronic leak detection do?
A sound membrane blocks the test current, but a hole lets it through. That’s how we locate breaches you can’t see.
How many surveys have you done?
We have more than 20 years’ experience and have completed over 5,000 surveys.
What if it rains on the day?
Light rain is typically fine; heavy rain and wind are different. In high wind or heavy rain, a drone cannot fly and access may not be safe, and we’d agree another day.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when you book.
Do you work in Oakleigh Park?
Yes. We cover Oakleigh Park and the rest of Greater London. For a price, ring 07833 053749 or use the contact form.
Tips that help
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Note where leaks show inside and when
- Don’t leave water getting in
- Test new membranes before covering them
- Don’t keep patching the same spot
You receive a report showing where each breach was found, with photos. Pass it to your roofer to repair the breach points.
Consider testing a new membrane before it’s covered. It’s easier to find holes before more layers are added.

Why act early in Oakleigh Park
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. 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.

Roof by roof
Single-ply membranes
Single-ply can be punctured by tools or fixings. Testing helps find them.
Bituminous membranes
Older felt roofs frequently have seams and patches that can leak. Testing depends on the roof.
Signs you need electronic leak detection in Oakleigh Park
Water travels under flat roof membranes. The stain inside can be far from the hole which makes it hard to find by looking.
Here are some of the things we see frequently:
- Leaks through a flat roof with no obvious cause
- Damage from equipment installers
- New membranes needing a check before handover
- Repairs that haven’t stopped the leak
If you let a flat or house near Oakleigh Park station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Before booking any roof surveyor
- Which parts of the roof they’ll actually see
- Their track record with similar roofs
- When you’ll get the report
- Whether you can ask questions once you have the report
What we do, step by step
Before we start, let us know why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting. In Oakleigh Park, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Before we arrive
- Let us know about parking near the property
- Agree roof access with the managing agent if it is shared
- Make sure pets are kept safely away
Arrange a survey
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. Otherwise, simply ring 07833 053749 or send us an email whenever suits you.
