Common questions in Oakthorpe Park
Do you carry out roof surveys in Oakthorpe Park?
We do. The survey and report are the same in Oakthorpe Park as anywhere else.
Will parking be an issue for a roof survey in Oakthorpe Park?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
What’s the best way to book?
Just ring 07833 053749 or send us an email with the address. We’ll ask a few questions, confirm the price and agree a date.
Is this an asbestos survey?
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.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when booking.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photos. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Will you go up on the roof?
Only if it’s safe. We check everything that can safely be seen: from the ground, from windows, from inside the roof space, from the roof where it is safe and by drone where applicable. The report says if anything couldn’t be seen.
Electronic leak detection in Oakthorpe Park: what you get
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It can be used to trace an existing leak or check a new membrane before handover. We quote for each roof based on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Let us know about your roof to find out more. We survey flat roof membranes, commercial flat roofs and green roofs, and people most often book us about leaks through a covered membrane and damage from equipment installers.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Oakthorpe Park, the flat roof is often a shared part of the building.
Where we can’t see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Places near Oakthorpe Park
What else we do in Oakthorpe Park
What we look for on each type of roof
Liquid-applied waterproofing
Pinholes in a coating can let water through. ELD can help locate them on suitable roofs.
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Laps and fixings are where holes frequently appear.
How it works
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit normally takes as long as needed for the roof’s area and construction, and we’ll give you a guide when quoting. London terraces rarely offer a view of the whole roof from one spot, so in Oakthorpe Park we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, tell us who can let us into the shared parts.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- 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.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- Jot down any questions you want answered
- Keep pets out of the way during the survey
- Unlock side gates and any roof access doors
Arrange a survey
Most bookings start with a short call: phone 07833 053749 or send us an email. You will have a price before anything is arranged.

What electronic leak detection looks like in Oakthorpe Park
Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Oakthorpe Park is one of them, bay roofs, hips and later dormers each have their own details. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 1.7 miles south-east lies Bruce Castle, a reminder of how long the area around Oakthorpe Park has been built on. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years.
Take an older house close to St Michael-at-Bowes: the joins between later flat roofs and the old walls are where problems typically start. Shop and office owners around The Mall Wood Green may find that flat roofs over shops and units are easy to forget until water comes through a ceiling. Take a building like St Anne's Catholic High School for Girls: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Should I look at the roof myself first?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Tips from our surveys
A little preparation and a few simple habits help. Our tips:
- Don’t let outlets block
- Tell us about the membrane and build-up if you know it
- Do not leave water getting in
- Don’t keep patching the same spot
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
What happens if roof problems are left?
Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first so your roofer knows where to work. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. When the stain finally shows, the damage underneath is often older than it looks.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
