About our electronic leak detection in Gun Hill
Our ELD testing covers flat roofs in Gun Hill and the rest of London and South East England. A visit typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. Electronic leak detection is quoted for your roof, because the method depends on the roof. You get a photo-illustrated written report. Common reasons to book are breaches around outlets and penetrations and new membranes needing a check before handover, across commercial flat roofs, roof terraces and balconies and flat roof membranes.
In a small place like Gun Hill, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, typically 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.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Electronic leak detection around Gun Hill
Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Horsham stone slab roofs survive on some old Sussex buildings, alongside oast houses and timber-framed Wealden hall houses. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. The wider area around Gun Hill has a long history of building, with Horselunges Manor about 1.9 miles south-east. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
Gun Hill is about 3 miles north-west of Hailsham, in East Sussex. Gun Hill gets the same service as everywhere else we work: a careful inspection, photographs and a written report. Gun Hill is one of the places in East Sussex where we work. Our Brighton page covers surveys nearby.

What affects the price in Gun Hill
Not every roof costs the same to survey, and it comes down to:
- Whether it’s a home or a commercial building
- Extra roofs, like extensions, dormers or garages
- How big the roof is
- Chimneys, valleys, parapets and other details
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.
Getting in touch
We will typically ask about:
- What’s prompted the survey
- Any photos you have, taken from ground level or a window
- Dates you’re working to, like exchange
- Where any leaks, stains or damp patches show inside
To book a survey, ring 07833 053749 or send us an email with the address and what you’d like to know about the roof. We will confirm the price before booking.
What electronic leak detection doesn’t cover
It’s useful to know what a survey will not do before you book:
- Roofs whose membrane or build-up is not suitable
- Leaks from plumbing or windows
- Sections we cannot safely access
If in doubt, ring 07833 053749 or email us and we’ll point you to the right survey. The full list of what we check.
What we check
- Green roofs
- Single-ply roofs
- Commercial flat roofs
- Flat roof membranes
- Liquid-applied waterproofing
- Roof terraces and balconies
What we look for on each type of roof
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Seams and penetrations are typical breach points.
Liquid-applied waterproofing
Pinholes in a coating can let water through. ELD can help locate them on suitable roofs.
Gun Hill questions
Is my home in Gun Hill listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you cover Gun Hill?
Yes, Gun Hill is one of the places we work. The survey and report are the same in Gun Hill as anywhere else, and visits run on weekdays and weekends.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
Do you look in the loft space?
If there is a loft and safe access to it, yes. From inside, the underside of the roof often shows damp, staining or daylight that cannot be seen from outside.
Will I get photos?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
Will you go up on the roof?
Only if it’s safe. We check everything that can be seen safely: from the ground, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. Anything we can’t see is noted in the report.
How many surveys have you done?
We’ve completed more than 5,000 surveys, across 20+ years of surveying roofs, and 98% of clients are satisfied.

How it works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. The inspection then takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a small place like Gun Hill, access is usually the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Tell us about any leaks, stains or damp patches you know of
- Find any records of previous roof work
- Make a note of anything you’d like us to look at
Book a survey
Every survey is priced before it is booked, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, phone 07833 053749 or drop us an email.

Do you need electronic leak detection in Gun Hill?
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
Problems we come across frequently include:
- Damp inside with no sign on the roof
- Patched roofs that still leak
- Waterproofing to test before it’s covered
- Punctures from foot traffic or tools
Around Gun Hill, as everywhere, small roof faults are simplest to sort before they let water in.
Choosing a roof surveyor
- Whether the inside of the roof is included
- What exactly goes into their report
- What’s outside the scope of the survey
- Whether they hold professional indemnity and public liability insurance
Tips that help
These tips come from what we see on roofs every week, before and after a survey:
- Do not leave water getting in
- Have roof specifications to hand
- Keep a note of leaks after rain
- Find the breach before more patching
Wet insulation may need attention after a leak. That is something to discuss with your roofer, and moisture readings can help.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
