Roof Leak Investigation in Duncton
A careful look at the leaking roof at your property in Duncton, and put it all in a report with photos.
- Damp ceilings under a flat roof
- Staining where a gutter or parapet meets the wall
- Staining around the chimney inside
How it works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, take photographs as we go and record our findings for the written report. It usually takes about one to two hours for most homes, though a hard-to-trace leak can take longer. Somewhere as small as Duncton, access is frequently the only tricky part. 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.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- We inspect inside and out, starting from the stain.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Before we arrive
- Agree roof access with the managing agent if it’s shared
- Clear the way to the loft hatch
- Let us know about parking before the day

Roof leak investigation in Duncton: what you get
Most roof leaks start at a joint rather than the middle of a slope. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. We check each likely route and we follow where the evidence leads. Every chimney, dormer and roof light adds more joints to check. We check all of them, from every safe vantage point. We survey slate and tile slopes, flat roof details and rooflights and dormers, and the problems we are asked to look at most are water dripping from rafters or underlay and staining around the chimney inside.
In a village or hamlet like Duncton, older cottages and farmhouses often have roofs that have been patched over many years. A new leak may be fresh damage or the latest sign of long-term wear, and the difference matters, especially to an insurer. We check whatever is safely visible and set out what we find. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
After the visit, you get a photo-illustrated written report, sent by email. It sets out the condition of the leaking roof, any defects and our written recommendations.

Different roofs, different checks
Flat roof upstands and outlets
The upturned edge of a flat roof covering keeps water out at walls. If it’s too low, cracked or poorly dressed, water gets behind it.
Lead flashings
Some roofs have mortar where you’d expect lead. Fillets crack and pull away over time, and water runs down behind them.
Why act early in Duncton
A small drip today can be a bigger leak after the next storm. Wind lifts loose slates further and gaps widen. An investigation now gives you time to plan the work. Where a roof is exposed, as many are in small places like Duncton, driving rain gets into any weakness, and damp in older walls is slow to dry out.
A Basic Survey starts from £150, inc. VAT. The Standard Survey starts from £250 and the Premium Survey from £400. We confirm the price for the job before you book.

Honest limits
Without opening up the roof, some things stay hidden, so a survey has limits:
- What’s under the covering or behind the plaster
- Leaks from plumbing, tanks or pipework rather than the roof
- Structural calculations (that’s a structural engineer’s job)

Roof leak investigations around Duncton
The wider area around Duncton has a long history of building, with Bignor Roman Villa about 2.4 miles south-east. Older homes in the wider area often have features worth a closer look, such as 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. In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. Some old buildings in Sussex have Horsham stone slab roofs. Different coverings let water in at different points, which shapes where the search starts.
For an older house near a landmark like Church of Holy Trinity, lead flashings, valleys and old chimneys are typical places for water to get in.

Other services in Duncton
Do you need a roof leak investigation in Duncton?
A chimney stack has lots of places for rain to get in. Eroded pointing, cracked flaunching, failed flashings and open pots can all be responsible. The damp may appear on a chimney breast, a ceiling or in the loft.
We’re frequently asked to look at:
- Condensation that looks like a leak
- Water coming in around a roof light or dormer
- Brown rings on upstairs ceilings
- Water dripping from rafters or underlay
Take a building like Duncton CofE Junior School: a leak through a large roof is frequently found some distance from where the water shows inside.

Questions from Duncton
Will you come out to Duncton?
We do. A small place gets exactly the same survey as a big one.
Do you carry out roof surveys in Duncton?
We do. Every survey there gets the same written report with photos.
Does this replace a RICS home survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
What does the report include?
You get our findings in writing, part by part, with photos, finishing with recommendations. The most urgent items are made clear.
Is thermal imaging part of a leak investigation?
It can, when the conditions are right. The best results come after a sunny day, on a dry roof with little wind. Damp areas can hold heat differently from dry ones. Its findings are confirmed with a moisture check.
Will you fly a drone over my roof?
Yes, where it’s applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
What you can safely check yourself
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
