How a roof leak investigation works in Bosham
On a flat roof, water can travel a long way under the covering. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Ponding water makes any weakness worse. We check both the covering and the room underneath to narrow it down. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt often lasts around 15 to 20 years, so age is part of the picture. If you’ve noticed a leak that comes and goes with the weather and condensation that looks like a leak, we can find out what’s behind it, on valleys and parapet gutters, chimney stacks and flat roof details alike.
Being in a small place like Bosham makes no difference to how a leak or storm damage is looked at: we simply plan the journey and access ahead. It’s useful to know where the water appears, in what weather, and what you’ve seen outside, plus any earlier repairs. If you have photos of the water coming in, they help as well.
The written findings come by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Wind, rain and roofs in Bosham
Bosham is within about 2 miles of the coast, and being near the sea means more wind and salt than a roof inland would face. In a coastal gale, rain is driven sideways into laps, verges and flashings. Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Horsham stone slab roofs survive on some old Sussex buildings. Each of these roof types has its own typical places for water to get in.
Warblington Castle lies about 4.9 miles west, so building around Bosham goes back a long way. On older roofs nearby, leaks often trace back to lead flashings, valleys and gutters. For site and facilities teams at buildings such as Bosham Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Bosham is about 3 miles west of Chichester, in West Sussex. Whether the building in Bosham is a house, a flat or a commercial unit, the roof can be surveyed on a weekday or at the weekend. Our West Sussex coverage includes Bosham. Our Portsmouth page covers surveys nearby.

Useful tips for Bosham property owners
Some practical points come up on survey after survey. They apply to most roofs:
- Keep water away from lights and sockets
- Write down the wind direction and rain when it leaks
- Let us know what has already been tried
- Check whether pipes or tanks run near the stain
We email the report to you, with photographs of what we found. It explains the likely entry point, the route the water takes and our recommendations. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Have leaves and moss cleared from gutters, valleys and outlets, ideally once the leaves have fallen. Blocked outlets on parapet and flat roofs cause many leaks. Leave the clearing to someone with the right equipment.
When to book a survey in Bosham
A gutter that overflows can soak a wall and mark the ceiling inside. Hidden gutters behind parapets cause the most trouble, since a blocked outlet sends water over the lining and into the building.
We’re often asked to look at:
- Wet patches on loft insulation
- Water coming in around a roof light or dormer
- Water that shows only in certain storms
- Damp underlay across a wide area
For landlords with property near Bosham station, a clear finding on where water gets in helps you brief a roofer straight away.

The survey, step by step
Safety comes first on every visit. Everything that can be seen safely is inspected, and anything we cannot see is noted in the report. The survey normally takes about one to two hours for a house; commercial roofs usually need 3–4 hours. For a village or hamlet like Bosham, the journey is planned in advance: let us know about lanes, gates and parking. On the day, we inspect everything that’s safely in view, inside and out.
- We start with your notes and photos of the leak.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Before we arrive
- Have keys ready for side gates, garages or roof access doors
- Make a note of anything you’d like us to look at
- Keep pets inside or away from the areas we’re looking at

Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, ring 07833 053749 or drop us an email.
Related advice
DIY checks: what’s safe
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
What a roof leak investigation does not cover
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- An intermittent leak that shows no trace on the day
- Putting the leak right
