Electronic leak detection in North Ockendon
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it is covered. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays, depending on the weather. Let us know about your roof to find out more. Common reasons to book are patched roofs that still leak and water coming in under a flat roof, across green roofs, single-ply roofs and flat roof membranes.
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. Which one is on a roof in North Ockendon shapes how it is checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Local flat roofs in North Ockendon
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 4.5 miles north-west lies Hare Hall, a reminder of how long the area around North Ockendon has been built on. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
For a London address like North Ockendon, it is useful to know about controlled parking before the day. For site and facilities teams at buildings like The James Oglethorpe Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Do you need electronic leak detection in North Ockendon?
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.

- Water coming in under a flat roof
- Breaches around outlets and penetrations
- Stains far from any visible defect
- Leaks under green or ballasted roofs
Shop and office owners around Ealing Broadway Centre may find that flat roofs over shops and units are easy to forget until water comes through a ceiling.

Common questions in North Ockendon
Can parking be tricky for a visit in North Ockendon?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Does a conservation area affect roof work in North Ockendon?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Can you tell me if my roof has asbestos?
No. We don’t carry out asbestos surveys or testing. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Do I need to be at home?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you when booking.
What happens after the survey?
You will 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.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when booking.
What happens on the day
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. From the street, a London terrace normally shows only its front slope or parapet, so a visit in North Ockendon moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- 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
- Check pets are kept safely away
- Have keys ready for side gates, garages or roof access doors
- If it is not your property yet, arrange access through the agent

Advice
DIY checks: what’s safe
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That is where a survey comes in, using safe viewpoints and a drone where it applies.
Rented homes, blocks and businesses
Letting agents frequently book on a landlord’s behalf, with the report sent to whoever needs it. Access is agreed with the tenant beforehand.
We also survey roofs for businesses and commercial landlords. Bigger roofs take more time.
What a survey costs
Prices always include VAT. The things that change the price are:
- House, block, shop or office
- Building height and the viewpoints available
- How big the roof is
- The number of roofs, including extensions and garages
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What to tell us when you get in touch
A little information up front helps. It is useful to include:
- What’s prompted the survey
- Your timetable, such as an exchange date
- Pictures of the roof from a safe spot, if you have them
- Whether there is a loft hatch, a shared roof or tricky access
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To get started, call 07833 053749 or drop us an email.
What this survey can’t tell you
Before you book, it’s worth knowing what a survey will not do:
- Some conductive membranes
- Leaks from walls, copings or rooflights
- Areas we can’t reach or that cannot be tested
If in doubt, ring 07833 053749 or drop us an email and we will point you to the right survey before booking. What a survey covers and does not.
