Electronic leak detection in Marden's Hill
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye, so your roofer can repair them. The results come in a report with photos. Common reasons to book are stains far from any visible defect and waterproofing to test before it’s covered, on green roofs, liquid-applied waterproofing and roof terraces and balconies.
In a village or hamlet like Marden's Hill, flat roofs are usually on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access in advance. If there are outbuildings or garages with flat roofs, mention them as you book.
The report is written in plain words, so you don’t need to be a roofer to follow it. Each point is backed by a photograph where possible, and recommendations are put by urgency where it matters.

Leave it or get it looked at?
Testing a new membrane before it’s covered is easier than tracing a leak later. Covered roofs are harder to test. In a small place like Marden's Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before you book.

What electronic leak detection looks like in Marden's Hill
Older houses across Sussex frequently 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. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. The wider area around Marden's Hill has a long history of building, with Groombridge Place about 3.8 miles north-east. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
Anyone responsible for a site like St John's Church of England Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. Landlords with a home close to Crowborough station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.

What we are asked to look at in Marden's Hill
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny but water still finds them.
Common reasons to book include:
- Water coming in under a flat roof
- Damp inside with no sign on the roof
- Leaks at pipes, outlets or fixings
- Failed seams and laps
Take an older house close to St John's Church: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

- Whether VAT is added on top
- Do they have a CAA Flyer ID and Operator ID for drone work?
- What the survey won’t cover
What you can safely check yourself
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.

FAQs for Marden's Hill
Do you cover Marden's Hill?
We do. Every survey there gets the same written report with photographs.
Is my home in Marden's Hill listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
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 recommend a specialist asbestos surveyor checks them before they’re disturbed.
Is this a RICS survey?
No. This is a survey of the roof only, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
How is ELD priced?
We quote for each roof individually. Tell us about the roof and where it leaks. Just call 07833 053749 or send us an email for a quote.
Will you walk on the roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and the report notes anything we couldn’t see.
How do you choose the testing method?
The roof decides the method. We’ll explain why when we quote.
