How electronic leak detection works in West Ashling
ELD can be carried out in more than one way. Low-voltage testing is normally done with the surface wet, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof and we explain which we will use. We’ll say if your roof does not suit either method before any testing starts. We survey single-ply roofs, liquid-applied waterproofing and commercial flat roofs, and the problems we are asked to look at most are damage from equipment installers and leaks showing away from the breach.
In a village or hamlet like West Ashling, flat roofs are typically on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access ahead of time. Garages and outbuildings are easy to forget, so mention any you want included as you book.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Signs you need electronic leak detection in West Ashling
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs, depending on the build-up.
A survey makes sense if you’ve noticed:
- Failed seams and laps
- Holes around roof penetrations
- Leaks through a covered membrane
- Damp inside with no sign on the roof
Landlords with a home close to Bosham station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Flat and commercial roofs around West Ashling
West Ashling lies within about 4 miles of the sea, where sea air brings more salt and stronger wind than inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. About 4.6 miles north-east lies West Dean House, a reminder of how long the area around West Ashling 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 the council can say whether a home is in a conservation area.
Take a building like Funtington Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. The streets around a church like The Parish Church of St Mary are often among the oldest in a place, and if your home is one of the older ones nearby, flat-roofed rear additions and dormers added over the years are worth checking.

Before and after the survey
There’s plenty you can do without going near the roof. Here’s what helps most:
- Clear flat roof outlets regularly
- Note where leaks show inside and when
- Share any drawings of the roof
- Use boards when working on the roof
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.
What we look for on each type of roof
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.
What this survey cannot tell you
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Roofs whose membrane or build-up isn’t suitable
- Leaks from plumbing or windows
- Moisture spread under the membrane
If you are not sure which survey you need, call 07833 053749 or send us an email and we will give you a straight answer. The full list of what we check.
What we check

- Roof terraces and balconies
- Liquid-applied waterproofing
The survey, step by step
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. The survey itself takes more time on a big roof than a small one, with the construction of the roof playing a part too. Rural addresses near West Ashling can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- 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.
Before the survey
- Jot down any questions you want answered
- Let us know about parking before the day
- Keep pets in another room

Advice
West Ashling questions
Do you cover smaller places like West Ashling?
Yes, we do. Our area covers London and the South East, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Is my home in West Ashling listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Let us know about the roof and where it leaks, and phone 07833 053749 or use the contact form for a quote.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing aren’t part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings.
How long will testing take?
Testing typically takes a length of time set by the size of the roof and how it’s built, and we’ll give you a guide when quoting.
Does this replace a RICS home survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
Do you need to get into the loft?
Where it is relevant to the survey and there’s safe access, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
