Electronic leak detection for homes and businesses in Hook Green
There are different ELD methods. Low-voltage testing is typically done with the surface wet, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. If neither method suits your roof, we will tell you at the outset. Typical surveys look at failed seams and laps and damp inside with no sign on the roof, on single-ply roofs, green roofs and flat roof membranes.
Somewhere as small as Hook Green, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access ahead of time. Garages and outbuildings are easy to forget, so mention any you want included when booking.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that’s said too.

Practical tips
There’s plenty you can do without going near the roof. What helps most:
- Avoid repeated repairs without finding the cause
- Limit access to the roof
- Keep outlets clear of debris
- Test new membranes before covering them
If anything in the report is not clear, ask us. We can talk you through the findings.
Don’t leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
Hook Green questions
Do roofs near the sea, like those around Hook Green, take more of a battering?
Yes, coastal weather is harder on roofs: there is more wind, and more salt in the air. Exposed details such as ridges, verges, flashings and metal fixings are the ones to watch, and Hook Green is within about 5 miles of the coast.
Do you cover smaller places like Hook Green?
Yes, Hook Green is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Do you use drones?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That lets us find breaches that are too small to see.
Will you check the loft?
Where it’s relevant to the survey and there is safe access, yes. Please clear anything stored under the hatch, and if the loft cannot be reached safely, the report says so.
Are you structural engineers?
No. We’re roof surveyors, not structural engineers, and it doesn’t include calculations. We’ll recommend an engineer if we see signs that call for one.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We look at the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Why act early in Hook Green
Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first so your roofer knows where to work. For an older or listed building in a place like Hook Green, repairs may need matching materials and consent, so leaving a defect until it’s urgent leaves less time to plan.

- Roofs whose membrane or build-up is not suitable

The survey, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting. You are welcome to ask questions while we are there. In a small place like Hook Green, access is usually the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Before we arrive

What else we do in Hook Green
Flat and commercial roofs around Hook Green
Hook Green lies within about 5 miles of the sea, and being near the sea means more wind and salt than a roof inland would face. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. With Cobham College about 3.9 miles south-east, Hook Green sits in an area with a long building history. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
If you let a flat or house near Longfield station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For an older house near a landmark like Church of St Nicholas, the flat roofs on later extensions tend to wear out long before the main roof.

Common roof problems in Hook Green
Joints and laps in a membrane can fail over time. A gap that’s hard to see can let water in long before anyone notices.
These are some of the problems a survey can pick up:
- Waterproofing to test before it’s covered
- Leaks at pipes, outlets or fixings
- Failed seams and laps
- Water coming in under a flat roof
Anyone responsible for a site like Sedley's Church of England Voluntary Aided Primary School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
Before you book any roof surveyor
