How electronic leak detection works in South Street
A leak in a flat roof frequently shows up a long way from where the water gets in. That makes leaks hard to trace by eye. ELD tests the waterproofing directly, to find where it has been breached. We test and report, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. We survey roof terraces and balconies, single-ply roofs and flat roof membranes, and the problems we are asked to look at most are leaking laps in the waterproofing and holes left by work on the roof.
In a small place like South Street, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
We keep jargon out of it: if work is needed, the report says so clearly.

What happens on the day
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. The inspection then takes longer on a large roof than a small one, with the construction of the roof playing a part too. Rural addresses near South Street can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Getting ready for the survey
- Unlock side gates and any roof access doors
- Move anything stored under the loft hatch
- For a flat or shared roof, check access with the building owner or managing agent

Advice
Why it’s worth a survey now in South Street
Some flat roof leaks come from walls or details. ELD helps rule the membrane in or out, so other causes can be checked. Older and listed buildings around South Street may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
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. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Why book with us
- Two decades and more of roof surveys
- Professional indemnity and public liability insurance
- Drones and thermal imaging where it applies
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID

Can I check my roof myself?
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.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.

More services for South Street
South Street: your questions answered
Is my home in South Street listed or in a conservation area?
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.
Is South Street within the area you cover?
Yes, South Street is covered. We survey roofs across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do I need to be at home?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you when booking.
Do you need to get into the loft?
If it is needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
How long will testing take?
It depends on the size of the roof and its build-up. You will know roughly how long before we start.
How do I book a survey in South Street?
Simply phone 07833 053749 or email us. We’ll ask a few questions, confirm the price and agree a date.
Tips that help
There is plenty you can do without going near the roof. What helps most:
- Ask contractors to protect the membrane
- Record dates and spots where water appears
- Consider ELD before paving or planting goes on
- Keep outlets clear of debris
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
ELD before paving, ballast or planting goes on is worth considering. It’s easier to find holes before more layers are added.
What a survey costs
Several things affect the price of a survey:
- Whether thermal imaging or a drone is needed
- The type of building, from a house to a block or an office
- Height and safe access
- The size of the roof
For a price for your roof in South Street, phone 07833 053749 or send us an email and tell us about the roof. The price is agreed before a date is set.
Getting in touch
To price your survey accurately, we’ll ask about:
- What made you get in touch
- Photos of the roof, taken safely from ground level or a window
- Where any leaks, stains or damp patches show inside
- Any deadline, such as an exchange date

What electronic leak detection looks like in South Street
Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Some old buildings in Sussex have Horsham stone slab roofs, and oast houses and timber-framed Wealden hall houses are part of East Sussex’s older buildings. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. If your home is older, it’s worth knowing whether it’s listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
If you own a rental within reach of Plumpton station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For site and facilities teams at buildings such as Chailey School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. Take an older house close to The Parish Church of St Peter: the flat roofs on later extensions tend to wear out long before the main roof.
