Electronic leak detection in Northend: what you get
Our ELD testing covers flat roofs in Northend and the rest of London and South East England. Testing typically takes a time that depends on the size of the roof and how it’s built, and we’ll give you a guide when quoting. Every roof is quoted on its size and build-up. The results come in a written report with photos. We survey flat roof membranes, roof terraces and balconies and single-ply roofs, and common reasons people get in touch are failed seams and laps and leaks through a covered membrane.
In a small place like Northend, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, normally show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that’s said too.

What electronic leak detection looks like in Northend
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Stonor Park, about 2.1 miles south, is one of the historic houses in the wider area around Northend. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
Around Northend, as everywhere, small roof faults are simplest to sort before they let water in.

The survey, step by step
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey normally takes a length of time set by the roof’s area and construction, which we set out in the quote. Somewhere as small as Northend, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
How to prepare
- Have any questions written down, so nothing gets missed
- Mention any parking restrictions on your street
- Find any records of previous roof work

What you can safely check yourself
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book.
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
What we cannot see
It is a careful look at the flat roof membrane, not the whole story. The main limits are:
- Roofs whose membrane or build-up is not suitable
- Repairing the breaches (that is for your roofer)
- The extent of water in the insulation
If you are not sure which survey you need, phone 07833 053749 or drop us an email and we’ll give you a straight answer before booking. What a survey covers and doesn’t.
Roofs we survey in Northend
- Roof terraces and balconies
- Green roofs
- Flat roof membranes
- Commercial flat roofs
- Single-ply roofs
- Liquid-applied waterproofing
Surveys for landlords and agents in Northend
Letting agents frequently book on a landlord’s behalf. We agree a time with the tenant beforehand.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
What affects the price in Northend
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- Commercial roofs and larger buildings
- The shape of the roof and its details
- If the survey needs thermal imaging or a drone
- How tall the building is and how easy the roof is to see
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
What we need to know
We will typically ask about:
- Any marks or damp showing indoors
- Any deadline, such as an exchange date
- Photos of the roof, taken safely from the ground or a window
- The kind of building and roof involved
Every survey is priced before it’s booked, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, call 07833 053749 or use the contact form.
How the survey changes by roof type
Liquid-applied waterproofing
Liquid waterproofing has no laps, but can still have thin spots or holes. Suitability for ELD depends on the system.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers but it depends on the layers.
Your questions about electronic leak detection in Northend
Is my home in Northend listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Will you come out to Northend?
Yes, we do. We cover the whole of London and South East England, and smaller places are part of that. Longer journeys are simply planned beforehand.
What happens after the survey?
You receive the written report by email, with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Just say which days work for you.
How do you choose the testing method?
The roof decides the method. We’ll explain why when we quote.
How do I book a survey in Northend?
Simply call 07833 053749 or drop us an email with the address. We will ask a few questions, confirm the price and agree a date.
Do you look in the roof space?
Normally, if there’s one and it can be reached safely. The loft space can show things the outside can’t, such as damp timbers, staining or daylight.
