Coggins Mill Electronic Leak Detection
Electronic leak detection for homes and businesses in Coggins Mill. More than 5,000 surveys completed across London and South East England.
- Damp inside with no sign on the roof
- Holes around roof penetrations
- Failed seams and laps
What happens if roof problems are left?
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. Matching old materials, like handmade tiles or stone slates, can take time to source. That’s one more reason to find defects before they become urgent.
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 the job before booking.

Electronic leak detection for homes and businesses in Coggins Mill
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see, so your roofer can repair them. You get a report with photographs of each breach found. We survey commercial flat roofs, single-ply roofs and liquid-applied waterproofing, and the problems we are asked to look at most are patched roofs that still leak and new membranes needing a check before handover.
Flat roofs on exposed homes in small places like Coggins Mill take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, frequently around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
Findings are set out part by part, from the coverings down to the gutters. You’ll see the good as well as the bad.

Before and after the survey
Here are a few things we’d tell any owner:
- Consider ELD before paving or planting goes on
- Limit access to the roof
- Find the breach before more patching
- Don’t let outlets block
If anything in the report is not clear, ask us. We can talk you through the findings.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
What we cannot see
No survey can tell you everything, and we’d rather be clear about that before you book. Keep these in mind:
- The extent of water in the insulation
- Build-ups without a suitable layer below
- Sections we can’t safely access
If in doubt, phone 07833 053749 or email us and we’ll suggest the right survey before booking. What a survey covers and doesn’t.

Surveys for landlords and agents in Coggins Mill
Letting agents can arrange access with tenants, at a time agreed ahead of time. We survey on any day of the week, which helps when tenants work during the week.
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photos included.
DIY checks: what’s safe
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.

How it works
Safety comes first on every visit. Everything that can be seen safely is inspected, and if part of the roof cannot be seen, the report says so. The survey usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere like Coggins Mill needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Preparing for the visit
- Leave a clear route to the loft
- Dig out any old roof reports or invoices
- For flats, check roof access has been agreed
How to book
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just phone 07833 053749 or email us when you are ready.

Local flat roofs in Coggins Mill
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, and oast houses and timber-framed Wealden hall houses are part of East Sussex’s older buildings. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 3.5 miles north-east lies Wadhurst Castle, a reminder of how long the area around Coggins Mill 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 a listed home or one in a conservation area may need consent for changes of material.
If you own a rental within reach of Wadhurst station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. For site and facilities teams at buildings such as Mayfield Church of England Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. The streets around a church such as Church of St. Dunstan are often among the oldest in a place, and if your home is one of the older ones nearby, flat-roofed rear additions and dormers added over the years are worth checking.

FAQs for Coggins Mill
Do you carry out roof surveys in Coggins Mill?
We do. The survey and report are the same in Coggins Mill as anywhere else, and visits run on weekdays and weekends.
Will you come out to Coggins Mill?
Yes, Coggins Mill is on our map. Villages and rural addresses get the same survey as a town house.
Will you go up on the roof?
Only when it is safe. Safety comes first, and fragile or steep roofs cannot always be walked on. Safe viewpoints, the loft and a drone where applicable let us see the rest.
How do you choose the testing method?
We choose the method that suits the roof. We will explain why when we quote.
What will the report tell me?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. The most urgent items are made clear.
How much does electronic leak detection cost?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. To get a quote, ring 07833 053749 or email us.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drones can’t fly safely in strong wind or heavy rain, and thermal imaging works best after a sunny day, with a dry roof and little wind. We will rearrange with you if the weather is not right.
