How much does electronic leak detection cost?
Each roof is quoted on its size and build-up. Let us know about the roof and where it leaks. Just call 07833 053749 or send us an email for a quote.
What’s in the survey report?
It explains what we saw, what it means and what we’d suggest, with photographs throughout. It also says if any part of the roof couldn’t be seen safely.
Will you repair the leak?
No. ELD is testing only. You get the breach locations with photos for your roofer to repair.
Does electronic leak detection work on all membranes?
ELD does not suit every roof. Certain membranes are conductive and some roofs lack the layer the test needs. We’ll tell you if yours isn’t suitable before testing.
Do you need to get into the loft?
If there is a loft and safe access to it, yes. The roof space can show things the outside can’t, like damp timbers, staining or daylight.
About our electronic leak detection in Furnace Wood
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or check a new membrane before handover. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays, depending on the weather. Let us know about your roof to find out more. If you’re worried about waterproofing to test before it’s covered and breaches hidden under paving or planting, a survey will tell you what’s going on, whatever the roof.
Somewhere as small as Furnace Wood, 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. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when booking.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later.

DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
Electronic leak detection around Furnace Wood
In Sussex, older roofs are frequently handmade clay tile, frequently with tile-hanging on the walls below. A few old Sussex buildings still carry heavy Horsham stone slabs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 3 miles south-east lies Saint Hill Manor, a reminder of how long the area around Furnace Wood has been built on. If your house is among the older ones, 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 East Grinstead station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We start with what you know about the roof and the leak.
