Leave it or get it looked at?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. Outbuildings and barns around Hamsey are easy to forget, but a failed roof there can spoil what’s stored inside. It’s worth including them in a survey before a winter does the damage.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your survey before booking.

Electronic leak detection in Hamsey: what you get
ELD finds breaches in the membrane but not every way water gets in. Water coming through walls, copings, rooflights or plumbing will not show on the test. We will tell you if we think the leak is coming from somewhere else. It will not show water getting in through brickwork or around frames. Our report keeps that distinction clear. You will also know what to check next. We survey flat roof membranes, roof terraces and balconies and green roofs, and common reasons people get in touch are leaks through a flat roof with no obvious cause and leaks that return after repairs.
Flat roofs on exposed homes in small places like Hamsey take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually 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, with a note and a photo for each point. It records what’s sound as well as what isn’t.

Practical tips
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Have roof specifications to hand
- Get leaks traced quickly
- Stay off the flat roof unless needed
- Check trades protect the waterproofing
Wet insulation may need attention after a leak. That is something to discuss with your roofer and other checks can help judge it.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.

How it works
It is useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere like Hamsey needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it’s safe.
- 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.
- You get a report with photos of each breach.
How to prepare
- Jot down any questions you want answered
- Note where any stains or damp appear
- Tell us about parking before the day
How to book
We survey roofs on weekdays, Saturdays and Sundays. To find a date that works for you, call 07833 053749 or send us an email.
Advice
Local flat roofs in Hamsey
Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. A few old Sussex buildings still carry heavy Horsham stone slabs, and the county’s older buildings include oast houses and Wealden hall houses. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 1.9 miles south lies Anne of Cleves House, a reminder of how long the area around Hamsey has been built on. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
Landlords with a home close to Cooksbridge station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you own one of the older houses in the streets near The Parish Church of St Peter, flat-roofed rear additions and dormers added over the years are worth checking. For site and facilities teams at buildings such as Hamsey Community Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.
Your questions about electronic leak detection in Hamsey
Do you cover smaller places like Hamsey?
Yes, Hamsey is covered. We work right across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Hamsey?
Yes, Hamsey is within the area we cover. We cover the whole of London and South East England. Just call 07833 053749 or use the contact form and let us know about the property.
Will I get photos?
Yes. The report includes photographs of what we found.
How long will testing take?
Testing usually takes a time that depends on the size of the roof and how it’s built, which we set out in the quote.
Can every flat roof be tested?
That depends on the roof’s membrane and layers. Share any details you have and we will check whether ELD will work.
Is the repair part of the test?
No, our part is finding the breaches. The report gives your roofer the locations.
Do you climb onto every roof?
Not unless it’s safe. Safe viewpoints, the loft space and a drone where applicable cover most of what’s needed, and anything out of sight is recorded in the report.
How we price electronic leak detection
The price reflects the time and kit the roof needs. That comes down to:
- The roof’s overall size
- The height of the building and how the roof can safely be seen
- How complicated the roof is, with its valleys, chimneys and parapets
- Whether thermal imaging or a drone is needed
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
Booking your survey
Some details help us suggest the right survey and price. When you contact us, tell us:
- Anything about access we should know
- Any stains, drips or damp patches you’ve seen indoors
- Why you want a survey: buying, a leak, a storm or new work
- The property’s address and postcode
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or email us when you’re ready.
Landlords, agents and block managers in Hamsey
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Let us know about it when you book and we will plan the survey around it.
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. Surveys run on weekdays and at weekends, which can make access easier.
