- Punctures from foot traffic or tools
- Breaches hidden under paving or planting
- A flat roof leak that cannot be traced
How it works
We check the roof from outside and, where it’s relevant and there is safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. Rural addresses near Walstead can be hard to find from a postcode alone, so a few directions are welcome. The visit itself is the same as anywhere else.
- You tell us 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 photographs shows where each breach is.
Preparing for the visit
- Keep pets out of the way during the survey
- Check the loft hatch can be reached
- Have any questions written down, so nothing gets missed

Electronic leak detection in Walstead: what you get
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. 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 when conditions allow. Let us know about your roof to find out more. We’re often asked to look into leaks showing away from the breach and breaches hidden under paving or planting, across roof terraces and balconies, liquid-applied waterproofing and single-ply roofs.
In a small place like Walstead, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, usually show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.
Findings are set out part by part, from the main slopes down to the gutters and outlets. It records what’s sound as well as what isn’t.

Practical tips
Nothing here needs a ladder. A few suggestions:

- Keep a note of leaks after rain
- Clear flat roof outlets regularly
- Check new waterproofing before handover
Questions about the results are welcome. We will explain what was found and what it means.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
What electronic leak detection looks like in Walstead
In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. A few old Sussex buildings still carry heavy Horsham stone slabs. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses such as Ockenden Manor, about 3.2 miles west, show how far back building in the area around Walstead goes. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
If you live in an older home near Church of the Good Shepherd, the joins between later flat roofs and the old walls are where problems typically start. If you look after a building such as Northlands Wood Primary Academy, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

What else we do in Walstead
What you can safely check yourself
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Different roofs, different checks
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
Green and ballasted roofs
Parts of the covering may have to come up. We explain what’s needed when we quote.
When to book a survey in Walstead
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
Here are some of the things we see frequently:
- Failed seams and laps
- Breaches hidden under paving or planting
- Leaks that return after repairs
- A flat roof leak that cannot be traced
If you own a rental within reach of Haywards Heath station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Questions to ask before booking
- Whether the roof space is looked at, where there is one

What if it rains on the day?
Light rain doesn’t typically stop a survey. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we’ll agree a new date if the weather is not suitable.
Does ELD work under paving or planting?
Sometimes. It depends on the build-up and the layers above the membrane, and some may need lifting. We talk this through first.
