Offington Electronic Leak Detection
A careful look at the flat roof membrane at your property in Offington, and put it all in a report with photos.
- Gaps at membrane joints
- Waterproofing to test before it is covered
- Damage from equipment installers
What we do, step by step
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Cottages and farmhouses around Offington frequently have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- For a flat or shared roof, check access with the building owner or managing agent
- Move anything stored under the loft hatch
- Jot down any questions you want answered

Advice
About our electronic leak detection in Offington
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it is covered. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Just ask about your roof. If you’re worried about holes left by work on the roof and new membranes needing a check before handover, a survey will tell you what’s going on, on green roofs, single-ply roofs and flat roof membranes alike.
In a small place like Offington, 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.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that’s said too.

FAQs for Offington
Does being near the coast affect roofs in Offington?
It can do. Within about 2 miles of the sea, as Offington is, metal fixings wear faster and gales find any loose ridge or slate.
Does a conservation area affect roof work in Offington?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
What’s the price of ELD?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. To get a quote, ring 07833 053749 or use the contact form.
Do I have to be there for the survey?
That depends on the survey. Inside the building and in the loft, we need someone to let us in; we will agree the details as you book.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Do you use low-voltage or high-voltage testing?
The roof decides the method. You’ll know which method we plan to use before we start.
Do you test for asbestos?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, like cement sheets or soffits on pre-2000 buildings.
Before and after the survey
Nothing here needs a ladder. A few suggestions:
- Keep a note of leaks after rain
- Do not let outlets block
- Check new waterproofing before handover
- Stay off the flat roof unless needed
You receive a report showing where each breach was found, with photos. Pass it to your roofer to repair the breach points.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
Electronic leak detection around Offington
Offington is within about 2 miles of the coast, and being near the sea means more wind and salt than a roof inland would face. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Older houses across Sussex frequently have handmade clay tiles, and many have tile-hanging on their upper walls. A few old Sussex buildings still carry heavy Horsham stone slabs. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
Take a building like Thomas A Becket Junior School: schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. For an older house near a landmark such as St Andrew's Church, flat-roofed rear additions and dormers added over the years are worth checking.

When to book a survey in Offington
Seams are a common weak point in flat roof waterproofing. A gap that’s hard to see can let water in for months before it shows.
Common reasons to book include:
- Damp inside with no sign on the roof
- Leaks through a covered membrane
- Failed seams and laps
- Waterproofing to test before it is covered
With Ecclesden Manor about 3.6 miles west, the area around Offington has a long history. If your home is older, its flat-roofed extension or dormer may be on its second or third covering.
Before you book any roof surveyor
- What the report includes, and whether it has photographs
- Is VAT included in the price?
- Their report turnaround times
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
When you need someone else
To be straight with you, a roof survey has limits:
- Parts of the roof covered by fixed equipment
- Leaks from plumbing or windows
- Build-ups without a suitable layer below
If in doubt, ring 07833 053749 or send us an email and we will suggest the right survey. What our survey covers.
Roof types and parts we check
- Commercial flat roofs
- Green roofs
- Single-ply roofs
- Flat roof membranes
- Liquid-applied waterproofing
- Roof terraces and balconies
Leave it or get it looked at?
Testing a new membrane before it is covered is easier than tracing a leak later. Covered roofs are harder to test. Outbuildings and barns around Offington are easy to forget, but a failed roof there can spoil what’s stored inside. It is worth including them in a survey before a winter does the damage.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.
