Roof Leak Investigation in Great Haseley
Tracing where water is getting into your roof for Great Haseley, from an experienced roof surveyor. You get a clear written report with photographs.
- A leak that comes and goes with the weather
- Leaks below a flat extension roof
- Condensation that looks like a leak
What we do, step by step
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. Most surveys take about 1–2 hours for most homes, though a hard-to-trace leak can take longer. Older roofs in small places like Great Haseley can have low, tight loft spaces, so it’s useful to know whether there is a loft hatch and how easy it is to reach. We only go where it is safe.
- You tell us where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe viewpoint.
- We email a written report showing where the water most likely gets in.
Getting ready for the survey

- Let us know where we can park nearby
- Make a note of anything you’d like us to look at

Advice
About our roof leak investigation in Great Haseley
On older houses, leaks frequently start at lead work and hidden gutters. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. A central valley gutter on a butterfly roof often turns out to be the source. Parapet walls and their gutters are checked from wherever it’s safe. Our report shows what we found, with photos. If you’ve noticed drips in the loft during heavy rain and drips from nail tips in a cold loft, a survey will tell you what’s going on, on valleys and parapet gutters, slate and tile slopes and lead flashings alike.
Roofs in small places like Great Haseley often stand in the open, where storms hit ridges, verges and chimneys hardest. Once water gets into older walls, it takes a long time to dry, so it pays to find the cause quickly. A written record also helps if you need to explain it to anyone else.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

What we are asked to look at in Great Haseley
Every flat roof covering has a working life. A felt roof often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Leaks often start at the edges, upstands and outlets.
It’s worth booking a survey if you’ve seen:
- Damp walls below an overflowing gutter
- Leaks at a dormer or roof window
- Ceiling stains that grow after rain
- Leaks that appear only in driving rain
The streets around a church such as Church of St Peter are often among the oldest in a place, and if you own one of the older houses nearby, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
What to check before booking
- Whether they hold professional indemnity and public liability insurance
- Whether VAT is added on top
- Whether you can ask questions once you have the report
- Whether the roof space is looked at, where there is one

Great Haseley roofs and the weather
Cotswold stone slates are found on older buildings in west Oxfordshire, and thatch survives in some of the county’s villages. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Knowing the roof type helps narrow down where water may be getting in. About 3.5 miles west lies Garsington Manor, a reminder of how long the area around Great Haseley has been built on. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
Take a building like Great Milton Church of England Primary School: water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.

Practical tips
Some practical points come up on survey after survey. They apply to most roofs:
- Don’t touch fittings that water is reaching
- Write down the wind direction and rain when it leaks
- Mention any plumbing above the damp area
- Put a bucket under the drip and move valuables
Keep the report after the work is done. If the leak returns, it’s a useful record of what was found.
Plan a roof survey every few years. Flashings, valleys and flat roof details are frequent weak points, and wear is easier to deal with before water gets in.
Can I check my roof myself?
Your own check is a good start, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
