Electronic leak detection in Great Hormead
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. The results come in a report with photos. We are frequently asked to look into breaches hidden under paving or planting and punctures from foot traffic or tools, across flat roof membranes, commercial flat roofs and roof terraces and balconies.
In a village or hamlet like Great Hormead, 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. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
We keep jargon out of it: where something needs attention, it says so plainly.

Prices for electronic leak detection in Great Hormead
We confirm the exact price before booking. These are the things that affect it:
- How tall the building is and how easy the roof is to see
- House, block, shop or office
- How many separate roofs there are, like extensions, dormers and garages
- The roof’s overall size
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.
What we need to know
Getting the details right at the start saves time. Please include:
- Any marks or damp showing indoors
- Any photos you have, taken from the ground or a window
- Whether there is a loft hatch, a shared roof or tricky access
- Any deadline, like an exchange date
Booking is simple: just ring 07833 053749 or use the contact form, let us know about the property and we’ll recommend the right survey. The price is agreed up front.
What electronic leak detection looks like in Great Hormead
An older home may be listed, or stand in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. Re-roofing in different materials may need permission there. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
The streets around a church like Church of St Nicholas are often among the oldest in a place, and if your house is among the older ones nearby, the joins between later flat roofs and the old walls are where problems usually start.

Should I look at the roof myself first?
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.
What you can’t do safely is get up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where it applies.
How the survey works
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect as long as needed for the roof’s area and construction, which we’ll explain when we quote. In a small place like Great Hormead, 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. Weekday and weekend visits are available.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- Find any records of previous roof work
- Keep pets inside or away from the areas we’re looking at
- Agree roof access with the managing agent if it is shared

Related advice
Do you need electronic leak detection in Great Hormead?
Water travels under flat roof membranes. The stain inside can be far from the hole, so tracing it by eye is difficult.
Look out for signs like these:
- Failed seams and laps
- Holes around roof penetrations
- Patched roofs that still leak
- Holes left by work on the roof
If you look after a building like Hormead Church of England (VA) First School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before booking anyone
- Will the report include photos?
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- What the survey won’t cover
- Whether the roof space is looked at, where there is one
What happens if roof problems are left?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. In a place like Great Hormead, a barn or garage roof left to fail puts whatever is inside at risk. It’s worth including them in a survey before a winter does the damage.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You’ll know the exact price before you book.
