Electronic leak detection in Barns Green
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We talk this through before we quote. Any details of the build-up help because they show what’s under the surface. If testing isn’t possible, we’ll say so. We are frequently asked to look into damp inside with no sign on the roof and waterproofing to test before it’s covered, across single-ply roofs, green roofs and liquid-applied waterproofing.
In a village or hamlet like Barns Green, flat roofs are normally on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when you book.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, with a note and a photo for each point. You’ll see the good as well as the bad.

- Leaks from walls, copings or rooflights
If you’re not sure which survey you need, call 07833 053749 or email us and we will give you a straight answer. What a survey covers and does not.

- Single-ply roofs
- Flat roof membranes
- Liquid-applied waterproofing
- Commercial flat roofs
- Green roofs
- Roof terraces and balconies
Rented homes, blocks and businesses
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time, and they’re priced for the size.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait.
What happens on the day
We don’t take risks to get a closer look. We inspect whatever is safely visible, and if part of the roof cannot be seen, the report says so. Most visits take more time on a big roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like Barns Green can have low, tight loft spaces, so tell us about the loft hatch and any ladder. We only go where it is safe.
- First, you tell us about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
Before we arrive
- Let us know about parking before the day
- For a flat or shared roof, check access with whoever owns or manages the building
- Find any records of previous roof work

Advice
What electronic leak detection looks like in Barns Green
Older buildings may be listed or sit in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. Re-roofing in different materials may need permission there. In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. Some old buildings in Sussex have Horsham stone slab roofs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
For site and facilities teams at buildings such as Barns Green Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Landlords with a home close to Christs Hospital station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Barns Green questions
Is Barns Green within the area you cover?
Yes. Barns Green is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
How do I find out if my home in Barns Green is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
How quickly is the report sent?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed.
Can you find leaks on a covered flat roof?
On some roofs, yes. What sits on the membrane affects the method so we check the roof first.
Do you use low-voltage or high-voltage testing?
The roof decides the method. You will know which method we plan to use before we start.
What is electronic leak detection?
A sound membrane blocks the test current, but a hole lets it through. That lets us find breaches that are too small to see.
What’s the best way to book?
It is easiest to call 07833 053749 or send us an email. Give us the address and some details about the roof. We survey on weekdays and at weekends.
Before and after the survey
A survey works best with a little help from you, before and after. Tips:
- Ask contractors to protect the membrane
- Test new membranes before covering them
- Find the breach before more patching
- Act on new leaks promptly
Wet insulation may need attention after a leak. That’s something to discuss with your roofer, and moisture readings can help.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
