Electronic leak detection in Northway
There are different ELD methods. Low-voltage testing is normally done with the surface wet, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof and we explain which we will use. If neither method suits your roof, we’ll tell you at the outset. If you’ve noticed leaks showing away from the breach and leaks that return after repairs, we can find out what’s behind it, whatever the roof.
In a smaller place like Northway, some flat roofs sit in the open, so wind catches loose edges and trims. Sun on a flat roof also ages felt and bitumen. The signs are splits, blisters and edges coming away, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
The report doesn’t just list problems. It explains what we found, why it matters and what we recommend.

What electronic leak detection doesn’t cover
Some things can’t be seen without opening up the roof, and that sets some limits:
- Parts of the roof covered by fixed equipment
- Carrying out the repair work
- Moisture spread under the membrane

Roofs we survey in Northway
- Single-ply roofs
- Green roofs
- Liquid-applied waterproofing
- Commercial flat roofs
- Flat roof membranes
- Roof terraces and balconies
Before and after the survey
Here are a few things we’d tell any owner, before and after a survey:
- Keep outlets clear of debris
- Limit access to the roof
- Consider ELD before paving or planting goes on
- Find the breach before more patching
Where the evidence points to walls, copings or rooflights, we’ll note it, so other causes can be checked.
Make sure contractors protect the waterproofing when they work up there. Have the roof looked at after other work.
Why act early in Northway
Not every leak is in the membrane. Testing shows whether the membrane is breached, so other causes can be checked. On a bungalow or cottage around Northway, the roof sits close to the rooms below, so a small leak can mark a ceiling within a few storms. Finding the cause first saves a second job inside.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.

Northway: your questions answered
How do I find out if my home in Northway is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Do you cover Northway?
Yes. Our area covers London and South East England, and Northway is part of that. Just phone 07833 053749 or email us and let us know about the property.
Does electronic leak detection work on all membranes?
Not every roof is suitable. Some membranes conduct electricity and some roofs lack the layer the test needs. If your roof won’t work, we’ll say so at the start.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Do you test for asbestos?
No. We do not sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
Will you check the loft?
If there is a loft and safe access to it, yes. The loft space can show things the outside cannot, like damp timbers, staining or daylight.
Will I get photos?
Yes. Photographs are part of every report, so you can see exactly what each finding refers to.
How the survey changes by roof type
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
Bituminous membranes
Bitumen roofs can often be tested electronically though the layers below matter.
Flat roofs in Northway
About 1.5 miles south-west lies Holywell Manor, a reminder of how long the area around Northway has been built on. Older homes in the wider area often have features worth a closer look, such as 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. West Oxfordshire’s older buildings frequently carry Cotswold stone slates, and a few villages in the county keep their thatch. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
Take an older house close to St Anthony of Padua: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. For businesses in and around places such as Clarendon Shopping Centre, a flat roof over a business is out of sight and out of mind until it leaks. If you own a rental within reach of Oxford station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

How it works
We don’t take risks to get a closer look. We inspect what can be seen safely, and if part of the roof can’t be seen, the report says so. Most visits take longer on a large roof than a small one, and the build-up of the roof makes a difference too. Some parts of a survey depend on the weather, so a visit to Northway is booked with the forecast in mind: drone flights and thermal imaging need the right conditions, while a look from ground level and the loft can go ahead in most weather.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Before we arrive
- Keep pets inside or away from the areas we are looking at
- Have keys ready for side gates, garages or roof access doors
- For a flat or shared roof, check access with the freeholder or managing agent
