About our electronic leak detection in Ellen's Green
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. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Tell us about your roof to find out more. If you are worried about holes around roof penetrations and waterproofing to test before it’s covered, a survey will tell you what’s going on, on commercial flat roofs, single-ply roofs and flat roof membranes alike.
Some older homes in villages like Ellen's Green are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Findings are set out part by part, from the main slopes down to the gutters and outlets, each with a short note and a photo. You’ll see the good as well as the bad.

What happens on the day
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take a length of time set by the roof’s area and construction, and we’ll give you a guide when quoting. Older roofs in small places like Ellen's Green can have low, tight loft spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.

Before and after the survey
There is plenty you can do without going near the roof. What helps most:
- Do not let outlets block
- Check trades protect the waterproofing
- Do not leave water getting in
- Record dates and spots where water appears
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Local flat roofs in Ellen's Green
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 fill the gaps in between, on extensions, garages, dormers and business premises. Listing and conservation areas can both shape what roof work is allowed on an older home. The council is the place to check, along with Historic England’s list, ideally before any re-roofing is planned.
If you let a flat or house near Warnham station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Whatever the street in Ellen's Green, a roof costs least to look after when faults are caught early.

Questions from Ellen's Green
Does a conservation area affect roof work in Ellen's Green?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Is Ellen's Green within the area you cover?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
What does the report include?
You get our findings in writing, part by part, with photos, finishing with recommendations. Points are put by urgency where it matters.
Which method do you use?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
What do I do with the report?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
How many surveys have you done?
Over 20 years and more than 5,000 surveys, across London and South East England.
What happens if roof problems are left?
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. Older cottages and farmhouses around Ellen's Green can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.

What we look at
- Single-ply roofs
- Commercial flat roofs
- Green roofs
- Liquid-applied waterproofing
- Flat roof membranes
- Roof terraces and balconies
Different roofs, different checks
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Bituminous membranes
ELD is often possible on bituminous membranes, depending on what’s below.
What affects the price in Ellen's Green
When we price a survey, we consider:
- How tall the building is and how easy the roof is to see
- If the survey needs thermal imaging or a drone
- Commercial roofs and larger buildings
- The roof’s overall size
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.
Getting in touch
Before you get in touch, it helps to have:
