Roof leak investigation in Lambourn
Water is good at hiding where it gets in. 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 often misses the real cause. Tracing the route first means any work can be aimed at the right place. Common reasons to book are a leak that comes and goes with the weather and drips in the loft during heavy rain, across the roof space, lead flashings and flat roof details.
In older homes around places like Lambourn, the underlay may be old bitumen felt, or there may be none at all. Without a sound underlay, any gap in the coverings lets water straight through. Whether it’s long-term wear or recent damage makes a difference to what happens next. Wet battens and insulation in the loft are frequently the first clue.
The report works through the roof section by section, from the coverings down to the gutters. It records what’s sound as well as what is not.

Do you need a roof leak investigation in Lambourn?
A gutter that overflows can soak a wall and mark the ceiling inside. Hidden gutters behind parapets cause the most trouble, because when they block, water backs up and runs inside.
Things that frequently lead to a survey include:
- Staining where a gutter or parapet meets the wall
- Leaks at a dormer or roof window
- Water that shows only in certain storms
- Water dripping from rafters or underlay
Take a building like Lambourn CofE Primary School: tracing a leak on a big roof starts with where the water appears and works back.

Roof leak investigations in Lambourn: local notes
Historic houses like Ashdown House, about 3.5 miles north-west, show how far back building in the area around Lambourn goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Knowing the roof type helps narrow down where water may be getting in.
Take an older house close to Church of St Michael and All Angels: old mortar, worn lead and slipped slates are the usual suspects when water gets in.

Why it’s worth a survey now in Lambourn
A leak near lights or wiring needs attention quickly. If water is reaching a light fitting or switch, keep clear of it. Finding where the water is getting in should follow right away. Around Lambourn, leaves and moss in gutters lead to overflowing water and damp walls, particularly where trees overhang. It is easy to sort the cause early and slow to dry a damp wall.

How the survey changes by roof type
Parapet and box gutters
A butterfly roof drains to a central valley gutter. If that gutter or its outlet fails, water can come through the top-floor ceiling.
Chimney stacks
A stack has several possible ways in for rain. Each is looked at from every safe viewpoint, and look for damp on the breast inside.
Questions from Lambourn
Is Lambourn within the area you cover?
Yes, Lambourn is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Is Lambourn in the area you cover?
Yes, Lambourn is one of the places we work. The survey and report are the same in Lambourn as anywhere else.
How long have you been surveying roofs?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys across London and the South East.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you will need a RICS survey as well.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. We look at the parts we are given access to.
Do you need to get into the loft?
Normally, if there’s one and it can be reached safely. The loft space can show things the outside can’t, such as damp timbers, staining or daylight.
Does someone need to be in?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access.
How the survey works
We check the roof from outside and, where it’s relevant and there is safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey typically takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. With a bit of garden around a house, as there often is around Lambourn, the roof can be viewed from several angles. Mention any side of the property we can’t get to. Inside, the loft is checked where it can be reached safely.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we look at the stain and the ceiling around 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
- Unlock side gates and any roof access doors
- Make a note of anything you’d like us to look at
- Show us where any leaks or stains appear

Honest limits
Without opening up the roof, some things stay hidden, so a survey has limits:
- Leaks from plumbing, tanks or pipework rather than the roof
- Defects hidden under coverings or inside walls without opening up
- Putting the leak right
