Roof leak investigations for homes and businesses in Halnaker
Some ‘leaks’ aren’t leaks at all. Condensation in a cold, poorly ventilated loft can drip from nails and timbers, and the stains look much like a leak. Knowing which it is means the right fix can be done, because they need very different work. The pattern of the damp, the ventilation and the timing all help us decide. If you’ve noticed ceiling stains that grow after rain and damp walls below an overflowing gutter, we can find out what’s behind it, on slate and tile slopes, flat roof details and rooflights and dormers alike.
Roofs in small places like Halnaker often stand in the open, where storms hit ridges, verges and chimneys hardest. Damp in old stone, brick or timber walls is slow to dry out, so it pays to find the cause quickly. A record with photographs is useful if you need to show the damage to anyone else.
We write the report in plain English, so you do not need to be a roofer to follow it. Photographs show what each point refers to.

Halnaker questions
How do I find out if my home in Halnaker is listed?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Do you cover Halnaker?
Yes, Halnaker is one of the places we work. The survey and report are the same in Halnaker as anywhere else.
Can thermal imaging help find my roof leak?
It can, when the conditions are right. It works best after a sunny day, with a dry roof surface and little wind. Wet insulation holds heat longer than dry, which can show up on the image. Its findings are confirmed with a moisture check.
Does the investigation include the repair?
A leak investigation finds and reports the likely source. The repair isn’t part of it. The report shows where the water gets in and what should be done, which whoever carries out the work can follow.
Will I get photos?
Yes, every report has them. Pictures sit next to the findings they show.
What’s in the survey report?
A photo-illustrated written report, covering the condition of the leaking roof, the defects we found and what we recommend, by urgency where it matters. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where applicable and structural analysis.
Are you structural engineers?
No. Visible signs such as deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.

Roof leak investigations in Halnaker: local notes
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. The covering and its details give the first clues when tracing where water is coming from. Historic houses like Goodwood House, about 1.4 miles west, show how far back building in the area around Halnaker goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
For an older house near a landmark such as The Priory Church of St Mary and St Blaize, old mortar, worn lead and slipped slates are the usual suspects when water gets in. If you own a rental within reach of Chichester station, a tenant living with a leak needs the cause found, not just the stain painted over.
Halnaker is about 3 miles north-east of Chichester, in West Sussex. If you’re in Halnaker, booking works exactly as it does anywhere else: a call or an email, a price, then a date. We cover towns and villages across West Sussex. Our Portsmouth page covers surveys nearby.

What happens on the day
On the day, we start by asking what you’ve noticed and what you want to find out. After that, we check everything we can see safely, using the ground, windows, the loft and a drone where it applies. The survey normally takes roughly 1–2 hours on an ordinary house, while a commercial roof takes nearer three to four hours. Rural addresses near Halnaker can be hard to find from a postcode alone, so a few directions are welcome. The visit itself is the same as anywhere else.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we look at the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe viewpoint.
- You receive a report with the likely source, photos and recommendations.
Before the survey
- Clear the way to the loft hatch
- Leave side gates unlocked
- Buyers: confirm access with the estate agent or seller
Arrange a survey
Once you know what you need, call 07833 053749 or send us an email. From there it’s a case of choosing a package, agreeing the price and fixing a day, weekday or weekend.

What we’re asked to look at in Halnaker
Condensation is often mistaken for a leak. Warm, moist air from the house rises into a cold roof space and condenses, particularly in lofts with blocked eaves. Drips from nails and damp underlay are typical signs.
Signs worth acting on include:
- Water coming in around a roof light or dormer
- Damp ceilings under a flat roof
- Damp walls below an overflowing gutter
- Water dripping from rafters or underlay
Anyone responsible for a site like Boxgrove CofE Primary School will know that a leak through a large roof is often found some distance from where the water shows inside.
Before booking any roof surveyor
- How much experience they have with roofs like yours
- Will they check the loft as well as the outside?
- Whether any drone flown is registered with the CAA
- What the report includes, and whether it has photographs
What a roof leak investigation doesn’t cover
Before booking, it is worth knowing what a survey will not do:
- What’s under the covering or behind the plaster
- A promise to find every leak on a single visit
- Whether rotten timbers meet design loads
If you are not sure which survey you need, ring 07833 053749 or email us and we will give you a straight answer before booking. What our survey covers.
What we check
- Rooflights and dormers
- Slate and tile slopes
- Flat roof details
- Lead flashings
- The roof space
- Valleys and parapet gutters
- Chimney stacks
Checking the roof from ground level
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we look at the roof.
