What happens on the day
Safety comes first on every visit. Everything that can safely be seen is inspected, and anything we cannot see is noted in the report. The survey normally takes about one to two hours at a typical home, rising to roughly 3–4 hours on a commercial building. With a bit of garden around a house, as there frequently is around West Horsley, the roof can be viewed from several angles. Mention any side of the property we cannot get to. Inside, the loft is looked at where it can be reached safely.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- From the loft space, we trace the water’s route where there’s safe access.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Before we arrive

Advice
How a roof leak investigation works in West Horsley
Roof leaks rarely show up where you’d expect. It can run along a rafter, a batten or the underlay before it drips, so a ceiling stain is rarely directly below the cause. Our leak investigation traces it back. Patching the spot above the stain frequently misses the real cause. Tracing the route first means any work can be aimed at the right place. We survey valleys and parapet gutters, flat roof details and the roof space, and common reasons people get in touch are staining around the chimney inside and leaks at a dormer or roof window.
In a smaller place like West Horsley, some roofs face open ground, so wind and driving rain find any weakness in ridges, verges and flashings. If a leak shows only when the wind is in a certain direction, that’s a useful clue. It is useful to know when and where the water appears. The gutters on the most exposed side can overflow too.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that’s said too.

What happens if roof problems are left?
If a leak has been ‘fixed’ before and has come back, the cause was probably missed. A careful investigation looks at every likely route, not just the obvious one. It gives the next repair a far better chance. Around West Horsley, leaves and moss in gutters lead to overflowing water and damp walls. Dealing with the cause is simple; drying out a wall is not.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Roof leak investigation starts from £150, including VAT.

Tips that help
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Note the weather when the leak shows
- Put a bucket under the drip and move valuables
- Don’t touch fittings that water is reaching
- Photograph the stain each time it appears
With the Standard Survey you get a follow-up consultation, while Premium includes one in person. It’s a chance to ask about anything in the report.
Check the loft after heavy rain, with care and a good torch. Look for drips, damp patches and stains on timbers. Photograph anything new.
What we look for on each type of roof
Slate and tile slopes
A gap in the coverings exposes the underlay. Older felt may hold for a while, but it tears with age.
Parapet and box gutters
Hidden gutters run behind parapets or between roofs. A blocked outlet sends water over the lining and into the building.

Knowing the roof type helps narrow down where water may be getting in. Historic houses like Hatchlands Park, about 1.6 miles south-west, show how far back building in the area around West Horsley goes.

Take a building like The Raleigh School: on a building that size, finding the source of a drip means looking well beyond the stain.
