Electronic leak detection in Halnaker: what you get
ELD finds breaches in the membrane but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. We will tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. You will also know what to check next. Typical surveys look at leaks through a covered membrane and holes around roof penetrations, across flat roof membranes, commercial flat roofs and single-ply roofs.
In a village or hamlet like Halnaker, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
The report works through the roof section by section, 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 is not.

How the survey works
On the day, we start by asking what you’ve noticed and what you’d like to know. After that, we look at everything we can see safely. Most surveys take longer on a large roof than a small one, with the construction of the roof playing a part too. Cottages and farmhouses around Halnaker often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen, and anything we cannot see is noted.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before we arrive
- Let us know where we can park nearby
- Jot down any questions you want answered
- Move anything stored under the loft hatch
How to book
We confirm the price for the job before you book, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, ring 07833 053749 or drop us an email.

What electronic leak detection looks like in Halnaker
With Goodwood House about 1.4 miles west, Halnaker sits in an area with a long building history. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. A few old Sussex buildings still carry heavy Horsham stone slabs. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Take a building like Boxgrove CofE Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you live in an older home near The Priory Church of St Mary and St Blaize, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Halnaker is about 3 miles north-east of Chichester, in West Sussex. In Halnaker, as across West Sussex, every roof gets the same careful survey. Across West Sussex, we cover Halnaker. Portsmouth is in our area too.

Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
Practical tips
These tips come from what we see on roofs every week, before and after a survey:
- Limit access to the roof
- Note where leaks show inside and when
- Don’t let outlets block
- Have roof specifications to hand
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Make sure contractors protect the waterproofing when they work up there. Check the roof after they’ve finished.
When to book a survey in Halnaker
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
Look out for signs like these:
- Leaks that return after repairs
- Leaks through a flat roof with no obvious cause
- Damp inside with no sign on the roof
- Leaks under green or ballasted roofs
Landlords with a home close to Chichester station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Questions to ask before booking
- What the report includes, and whether it has photos
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether VAT is added on top
- Whether the inside of the roof is included
Should I look at the roof myself first?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
What you can’t do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That’s where a survey comes in.
Your questions about electronic leak detection in Halnaker
Do you carry out roof surveys in Halnaker?
Yes, Halnaker is within the area we cover. We work right across London and South East England. Just phone 07833 053749 or use the contact form and let us know about the property.
Will you come out to Halnaker?
We do. Villages and rural addresses get the same survey as a town house.
Can you survey in bad weather?
It depends on the weather and the survey. In high wind or heavy rain, a drone cannot fly and access may not be safe, and we’d agree another day.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are frequently shared, so we need permission from whoever owns or manages the building. We inspect only the parts we’re allowed to reach.
Does someone need to be in?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
Do you carry out surveys on Saturdays and Sundays?
We carry out surveys on weekdays, Saturdays and Sundays. To find a day that suits you, call 07833 053749 or send us an email.
