Electronic leak detection in Lower Horncroft, West Sussex

Leave it or get it looked at?
Patching where you think the leak is often misses it. Testing shows where the membrane is actually breached. Older cottages and farmhouses around Lower Horncroft can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
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.

Electronic leak detection in Lower Horncroft: what you get
There are different ELD methods. Low-voltage testing is normally done with the surface wet and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof and we explain which we’ll use. We will say if your roof doesn’t suit either method at the outset. We survey commercial flat roofs, flat roof membranes and single-ply roofs, and common reasons people get in touch are punctures from foot traffic or tools and waterproofing to test before it’s covered.
In a small place like Lower Horncroft, 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. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
Where we can’t see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

DIY checks: what’s safe
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
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.
The survey, step by step
Once we have finished looking, we write up our findings in a report with photographs, emailed to you. As for time on site, most surveys take as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. Rural addresses near Lower Horncroft can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We start with what you know about the roof and the leak.
- 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.
- You get a report with photos of each breach.
How to prepare
- Check pets are kept safely away
- Point out any leaks or damp patches
- Have any questions written down, so nothing gets missed
Booking a survey
If you are buying, it’s useful to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just phone 07833 053749 or use the contact form when you are ready.
Advice
Before and after the survey
Over many surveys, some simple habits stand out:
- Have roof specifications to hand
- Find the breach before more patching
- Do not leave water getting in
- Limit access to the roof
If water has been getting in, insulation under the membrane may be wet. That’s something to discuss with your roofer and other checks can help judge it.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
Lower Horncroft questions
Do you cover smaller places like Lower Horncroft?
Yes, smaller places are covered as well as towns. We survey roofs across London and South East England. Just mention lanes, gates or anything else about the route when booking.
Is my home in Lower Horncroft listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photos. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
How many surveys have you done?
We have more than 20 years’ experience and have carried out more than 5,000 surveys across London and South East England.
Do you look in the loft space?
If it’s needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement.
Will you walk on the roof?
Not always. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the loft space and a drone where it applies.
Can you tell me if my roof has asbestos?
No. We don’t carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
What affects the price in Lower Horncroft
Prices vary from roof to roof, for these reasons:
- How tall the building is and how easy the roof is to see
- The shape of the roof and its details
- The type of building, from a house to a block or an office
- The use of thermal imaging or a drone
What a survey costs comes down to the roof itself: its size, its height, how many sections it has 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.
Booking your survey
To price your survey accurately, we will ask about:
- Any stains, drips or damp patches you’ve seen indoors
- What kind of property and roof it is
- What made you get in touch
- Pictures from the garden or a window, if you have them
If you have photos of the roof, send them over. Pictures from ground level or a window are fine, and please don’t climb up for a closer look. To get started, call 07833 053749 or drop us an email.
Flat and commercial roofs around Lower Horncroft
About 2.2 miles south-west lies Bignor Roman Villa, a reminder of how long the area around Lower Horncroft has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. Some old buildings in Sussex have Horsham stone slab roofs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you let a flat or house near Pulborough station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For an older house near a landmark like Church of St Agatha, the joins between later flat roofs and the old walls are where problems normally start.

Common roof problems in Lower Horncroft
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
Typical things we are asked to look at include:
- Gaps at membrane joints
- Punctures from foot traffic or tools
- Patched roofs that still leak
- New roofs to check before paving or planting
Take a building like Fittleworth CofE Village School: a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.
