Roof leak investigation in Three Bridges, West Sussex
Independent roof leak investigations in Three Bridges. We’ve completed more than 5,000 surveys across London and South East England.
- Damp ceilings under a flat roof
- Water coming in around a roof light or dormer
- Water marks that spread in wet weather
How it works
We don’t take risks to get a closer look. Everything that can be seen safely is inspected, and anything we can’t see is noted in the report. The survey normally takes between one and two hours for a house, though large, tall or awkward roofs take more time. Being in a smaller place like Three Bridges does not change how the visit works: we look from the ground, from windows, from the loft and from the roof where it’s safe. It helps to show us anything you’ve already noticed.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the loft space, we trace the water’s route where there’s safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from each safe vantage point.
- You receive a report with the likely source, photos and recommendations.
Before the survey
- If the roof is shared, arrange access with whoever manages the building
- Make sure pets are kept safely away
- Leave a clear route to the loft
Arrange a survey
Roof leak investigation starts from £150, including VAT. What you pay depends on the roof’s size, access and the package, so ring 07833 053749 or use the contact form with the details.

Roof leak investigation in Three Bridges
The aim is to find where the water is getting in and explain it. The report shows, with photos, where we believe the water gets in and how it travels, and recommends what should be done. Whoever does the work then has a clear starting point. We find and report the source, while the repair is a separate matter. Typical surveys look at wet patches high on an inside wall and water marks that spread in wet weather, on flat roof details, valleys and parapet gutters and rooflights and dormers.
Chimney stacks on older houses around places like Three Bridges can let water in, through worn flaunching, failed pointing or lifted flashings. Damp in a chimney breast can have more than one cause, so it isn’t always obvious where it starts. It is worth looking at the stack from outside and at the timbers beside it in the loft.
After the visit, you get a written report with photos, emailed to you. It explains the condition of the leaking roof, the defects we found and what we recommend.

Checking the roof from ground level
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That is where a survey comes in.
Your questions about roof leak investigations in Three Bridges
Should a flat-roofed garage or porch in Three Bridges be checked too?
Usually, yes: let us know about it as you book so the visit can include it. Flat-roofed garages and porches are common in new towns like Crawley, and older felt coverings may be near the end of their life.
How do I find out if my home in Three Bridges is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
What happens next?
You’ll receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
Do you look in the roof space?
Where it’s relevant to the survey and there’s safe access, yes. A clear path to the hatch helps.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
How long does the visit take?
It normally takes an hour or two for a house, with bigger or more complicated roofs taking longer. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Why get it checked now?
Leaks tend to get worse, not better. Wind lifts loose slates further and gaps widen. Tracing it now lets you plan the work rather than react to it. Around Three Bridges, a leak in an older house can soak into timbers and plaster, which is far harder to put right than the roof fault itself.
Prices quoted always include VAT, and the report isn’t charged as an extra. Our price is from £150, including VAT. Where your roof sits in the range depends on its size, height and access.

What a roof leak investigation looks like in Three Bridges
Three Bridges is part of Crawley, one of the post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Low pitches let wind-driven rain reach further under the tiles, and flat-roofed garages and porches are common leak points. Many older homes in Sussex have handmade clay tiles and tile-hung walls. Some old buildings in Sussex have Horsham stone slab roofs. Each of these roof types has its own typical places for water to get in.
Trees in and around Grattons Park shed leaves that can end up in nearby gutters, and blocked gutters overflow and soak walls. For site and facilities teams at buildings such as Pound Hill Junior School, a leak through a large roof is frequently found some distance from where the water shows inside.
Three Bridges is about 1 mile east of Crawley, in West Sussex. In Three Bridges, as across West Sussex, every roof gets the same careful survey. Across West Sussex, we cover Three Bridges.

What we look for on each type of roof
Chimney stacks
We look at the outside of the stack and the breast inside, not a flue, gas or sweep inspection.
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. If it’s too low, cracked or poorly dressed, water gets behind it.
Prices for roof leak investigations in Three Bridges
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- House, block, shop or office
- Any need for thermal images or a drone flight
- Extra roofs, like extensions, dormers or garages
- Features like valleys, chimneys, dormers and parapets
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.
Getting in touch
We will normally ask about:
- Whether there is a loft hatch, a shared roof or tricky access
- What made you get in touch
- When you need the report by
- Any photos you have, taken from the ground or a window
A quick phone call is usually the easiest start: ring 07833 053749 or email us, and we’ll ask about the building and what you need. You’ll have a price before anything is arranged.
What we are asked to look at in Three Bridges
When a slate slips or a tile cracks, the underlay takes the water. Ageing felt underlay eventually tears and lets water through, while some very old roofs have nothing under the coverings. Corroded nails, known as ‘nail fatigue’, are a frequent cause on slate roofs.
These are some of the problems a survey can pick up:
- Water coming in around a roof light or dormer
- Water that shows only in certain storms
- Leaks below a flat extension roof
- Brown rings on upstairs ceilings
Landlords with a home close to Three Bridges station may find that tracing a leak quickly matters when a tenant is living with it.
