Roof leak investigations for homes and businesses in Wiston
The aim is to find where the water is getting in and explain it. You get a written report with photos showing the likely entry point and the route the water is taking, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. We find and report the source, while the repair is a separate matter. We survey valleys and parapet gutters, slate and tile slopes and flat roof details, and common reasons people get in touch are a leak that comes and goes with the weather and wet patches high on an inside wall.
For a small place like Wiston, the inspection is the same as anywhere: we simply plan the journey and access ahead. It helps to know where the water appears, in what weather, and what you’ve seen outside, along with any repairs done before. Photographs of the stain and of the roof from outside are helpful too.
Every survey ends with a written report, with photographs, emailed to you. It sets out the condition of the leaking roof, any defects and our written recommendations.

How the survey changes by roof type
Valleys
Debris in a valley slows the water and pushes it sideways. In heavy rain, it can spill under the edges of the slates or tiles.
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. A blocked outlet leaves water standing, which tests every joint. Outlets and the area around them are checked.
What else we do in Wiston
What we do, step by step
After the inspection, everything we found is written up in a report with photographs, emailed to you. On timing, it usually takes an hour or two for a house, and longer for a large or complex roof. Older rural homes like those around Wiston can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- You get in touch with details of the leak and any photos.
- The visit starts indoors, at the stain and in the loft.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- We use moisture detection, and thermal imaging where it is useful.
- We email a report with photographs, the likely entry point and recommendations.
Preparing for the visit
- Check we can get to the back of the property
- Keep pets inside or away from the areas we’re looking at
- Note where any stains or damp appear

Wiston questions
How do I find out if my home in Wiston is listed?
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 Wiston?
We do. The survey and report are the same in Wiston as anywhere else, and visits run on weekdays and weekends.
Can you give me structural calculations?
No. We are roof surveyors, not structural engineers, and it does not include calculations. We’ll recommend an engineer if we see signs that call for one.
How long does a roof leak investigation take?
It usually takes about 1–2 hours for a house, and longer for a large or complex roof. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
What will the report tell me?
You get our findings in writing, part by part, with photos, finishing with recommendations. The most urgent items are made clear.
How should I prepare for the leak investigation?
Keep a note of when it leaks. Clear access to the loft. Keep away from any light or socket that water is reaching.
Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days when you book.
Wiston roofs and the weather
Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. Horsham stone slab roofs survive on some old Sussex buildings. Knowing the roof type helps narrow down where water may be getting in. What can be done to an older roof may depend on listing or a conservation area. The council is the place to check, along with Historic England’s list.
If you live in an older home near All Saints Church, lead flashings, valleys and old chimneys are typical places for water to get in.

Before and after the survey
A survey works best with a little help from you, before and after. Tips:
- Record whether it leaks in every downpour or only some
- Don’t climb onto the roof to look
- Let us know if there are tanks or pipes in the loft
- Tell us about any past repairs to the roof
With the Standard Survey you get a follow-up consultation, and Premium includes an in-person consultation. It’s a chance to ask about anything in the report.
Have flashings and flat roofs looked at every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.
What we’re asked to look at in Wiston
Flat roofs fail with age and wear. A felt roof often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Leaks often start at the edges, upstands and outlets.
A survey can pick up problems such as:
- Staining where a gutter or parapet meets the wall
- Damp ceilings under a flat roof
- Staining around the chimney inside
- Leaks at a dormer or roof window
In and around Wiston, as anywhere, a roof is easiest to deal with when its problems are found early.
What to check before booking
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Whether they hold professional indemnity and public liability insurance
- What happens after the report arrives
- When you will get the report
