About our roof leak investigation in Chalgrove
Roof leaks rarely show up where you’d expect. Water often travels along timbers or underlay before it finds a way down, so a ceiling stain is rarely directly below the cause. Our leak investigation traces it back, one likely route at a time. A repair aimed only at the stain can miss the cause entirely. Tracing the route first means any work can be aimed at the right place. Typical surveys look at stains around a skylight and damp ceilings under a flat roof, across chimney stacks, rooflights and dormers and slate and tile slopes.
Around Chalgrove, chimneys on older homes are a common source of leaks, at the flashings, the pointing or the mortar round the pots. Damp in a chimney breast can have more than one cause, so it is not always obvious where it starts. The stack, its flashings and the loft space beside it are all worth checking.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Roof leak investigations in Chalgrove: local notes
West Oxfordshire’s older buildings frequently carry Cotswold stone slates, and a few villages in the county keep their thatch. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. Adwell House, about 4 miles north-east, is one of the historic houses in the wider area around Chalgrove. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
For site and facilities teams at buildings like Chalgrove Community Primary School, on a building that size, finding the source of a drip means looking well beyond the stain.

How the survey changes by roof type
Valleys
A valley takes the rain from both sides of the roof. Worn or split linings and slipped valley tiles let it under the coverings.
Slate and tile slopes
A gap in the coverings exposes the underlay. Older felt may hold for a while, but it tears with age.
When you need someone else
In fairness, a roof survey has limits:
- Leaks from plumbing, tanks or pipework rather than the roof
- What’s under the covering or behind the plaster
- A structural engineer’s report

Roofs we survey in Chalgrove
- The roof space
- Flat roof details
- Lead flashings
- Slate and tile slopes
- Chimney stacks
- Valleys and parapet gutters
- Rooflights and dormers
How it works
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes roughly 1–2 hours for a house, with bigger or more complicated roofs taking longer. With a bit of garden around a house, as there frequently is around Chalgrove, the roof can be viewed from several angles. Let us know if any side is fenced off or hard to reach. Inside, the loft is looked at where it can be reached safely.
- We start with what you’ve seen: where the stain is and when it gets worse.
- Inside, we check the damp area and the loft space above it.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- We use moisture detection, and thermal imaging where it’s useful.
- We email a report with photos, the likely entry point and recommendations.
Before the survey
- Show us where any leaks or stains appear
- Dig out any old roof reports or invoices
- Let us know about parking near the property

Related advice
Chalgrove: your questions answered
Is my home in Chalgrove listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you cover smaller places like Chalgrove?
Yes. Chalgrove is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when booking.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Will you fly a drone over my roof?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Will you fix the leak as part of this?
This service finds and reports the cause, not to carry out the repair. With the report, a roofer knows exactly where to look.
What happens after the survey?
You’ll get the report by email, with photographs and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
Are you insured?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
Signs you need a roof leak investigation in Chalgrove
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 frequently start at the edges, upstands and outlets.
Signs worth acting on include:
- Water that shows only in certain storms
- Stains around a skylight
- Ceiling stains that grow after rain
- Water through the ceiling under a flat roof
Take an older house close to Church of St Mary: the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Questions to ask before booking
- Their drone registration, if they fly one
- Whether the loft space is looked at, where there is one
- Whether you get a written report with photos
- How long the report takes to arrive

Practical tips
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Some tips:
- Record whether it leaks in every downpour or only some
- Clear the loft hatch so we can get in
- Take dated photos of the leak
- Have an electrician check any wet fittings
The report gives whoever carries out the work a clear starting point. They’ll see exactly where the problem is, rather than at the stain.
Check the loft after heavy rain, with care and a good torch. Look for drips, damp patches and stains on timbers. Photograph anything new.
