How electronic leak detection works in Northam
Our ELD testing covers flat roofs in Northam and the rest of London and South East England. A visit normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. Every roof is quoted on its size and build-up. The results come in a written report with photos. If you’ve noticed waterproofing to test before it’s covered and leaks through a flat roof with no obvious cause, we can find out what’s behind it.
Around a smaller place like Northam, flat roofs normally cover extensions, garages and dormers. Even a small flat roof can let lots of water into the room below. Knowing the covering and how it was laid tells you what to expect from it, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
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.

Signs you need electronic leak detection in Northam
On a flat roof, water spreads under the waterproofing. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
Common reasons to book include:
- Holes left by work on the roof
- Leaks that return after repairs
- Gaps at membrane joints
- Water coming in under a flat roof
If you run a hotel or guest house in or near Northam, a roof problem can mean rooms out of use, so it pays to find faults before guests do.
Choosing a roof surveyor
- Whether they hold professional indemnity and public liability insurance
- Whether VAT is added on top
- How long they’ve been surveying roofs
- Which viewpoints they use to see the roof
Local flat roofs in Northam
Northam lies within about 2 miles of the sea, where sea air brings more salt and stronger wind than inland. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. About 1.3 miles south-west lies Southampton Tudor House and Garden, a reminder of how long the area around Northam 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.
For an older house near a landmark such as Church of St Augustine, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. If you let a flat or house near Bitterne station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Northam questions
Do you look at commercial flat roofs near Northam, like hotels?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
Is the coastal weather around Northam hard on roofs?
Often, yes. Northam is within about 2 miles of the sea, and coastal roofs tend to see faster wear on metal parts and more wind lifting loose pieces.
Do you climb onto every roof?
Only when it is safe. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the loft space and a drone where it applies.
Do you take photos of the roof?
Yes. Photos are part of every report, so you can see exactly what each finding refers to.
What’s the best way to book?
To arrange a survey, call 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
Do you cover Northam for electronic leak detection?
Yes. We survey roofs across London and South East England, and that includes Northam.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. You’ll know roughly how long before we start.
How it works
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. Most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. Parking around Northam is usually easier than in a town centre, but mention lanes, gates or long drives. On bungalows and lower roofs, much can be seen from ground level, with the loft showing the underside, while taller roofs may need other vantage points or the drone where applicable.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.

DIY checks: what’s safe
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
How we price electronic leak detection
Prices vary from roof to roof, for these reasons:
- The type of building, from a house to a block or an office
- Whether thermal imaging or a drone is needed
- The height of the building and how the roof can safely be seen
- The size of the roof
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your survey before booking.
Booking your survey
To price your survey accurately, we’ll ask about:
- Pictures from the garden or a window, if you have them
- Why you want a survey: buying, a leak, a storm or new work
- What kind of property and roof it is
- When you need the report by
To arrange a survey, ring 07833 053749 or email us and let us know the address and what’s prompted the survey. We’ll confirm the price before booking.
Leave it or get it looked at?
Some breaches are too small to see. Electronic testing can find breaches you cannot see by eye where the roof suits it. Around Northam, leaves and moss in gutters lead to overflowing water and damp walls, especially where trees overhang. Dealing with the cause is simple; drying out a wall is not.
