The survey, step by step
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey usually takes a time that depends on the membrane area and the build-up, which we set out in the quote. Around Coursehorn, older homes can have small or awkward roof spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Getting ready for the survey
- Keep pets inside or away from the areas we are looking at
- Gather any invoices or paperwork from past roof work
- Leave side gates unlocked
Arrange a survey
Booking is simple: just call 07833 053749 or send us an email, let us know about the property and we’ll point you to the right survey. We confirm the price before anything is booked.

Electronic leak detection in Coursehorn: what you get
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use, and some may need lifting. We talk this through before we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. If testing is not possible, we will say so. If you’ve noticed holes left by work on the roof and holes around roof penetrations, a survey will tell you what’s going on, whatever the roof.
Flat roofs on exposed homes in small places like Coursehorn take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, normally show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Flat roofs in Coursehorn
Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand, before anyone quotes for re-roofing. Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Take an older house close to Church of St Dunstan: flat-roofed rear additions and dormers added over the years are worth checking.

Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when booking, as it helps us focus the survey.

Your questions about electronic leak detection in Coursehorn
Is my home in Coursehorn listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Do you cover smaller places like Coursehorn?
Yes, Coursehorn is covered. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
What will the report tell me?
It works through the roof part by part, in writing and with photos, finishing with recommendations. Points are put by urgency where it matters.
Can you test a green or ballasted roof?
On some roofs, yes. What sits on the membrane affects the method, so we check the build-up first.
Can you survey in bad weather?
Light rain is typically fine; heavy rain and wind are different. In strong wind or a downpour, a drone can’t fly and access may not be safe, and we’d agree another day.
How much does electronic leak detection cost?
We quote for each roof individually. Send us details of the roof, and ring 07833 053749 or drop us an email for a quote.
How much time does ELD need?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
What electronic leak detection does not cover
A survey is a proper look at the flat roof membrane, but it cannot do everything. The main limits are:
- Roofs whose membrane or build-up is not suitable
- Repairing the breaches (that is for your roofer)
- Moisture spread under the membrane
If in doubt, call 07833 053749 or use the contact form and we’ll point you to the right survey. What our survey covers.

- Roof terraces and balconies
- Liquid-applied waterproofing
- Commercial flat roofs
- Green roofs
- Single-ply roofs

Useful tips for Coursehorn property owners
Over many surveys, some simple habits stand out:
- Keep a note of leaks after rain
- Tell us about the membrane and build-up if you know it
- Don’t leave water getting in
- Don’t let outlets block
File the report with your roof paperwork. It’s a dated record of the membrane’s condition.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
Common roof problems in Coursehorn
Repeated leaks after repairs suggest the real breach hasn’t been found. Electronic testing helps pinpoint it.
A survey can pick up problems such as:
- Stains far from any visible defect
- Leaks through a covered membrane
- Patched roofs that still leak
- Breaches around outlets and penetrations
If you look after a building like Cranbrook School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
