When you need someone else
A survey is a careful look at the leaking roof, but it can’t do everything. Its limits include:
- Structural calculations (that’s a structural engineer’s job)
- Defects hidden under coverings or inside walls without opening up
- Putting the leak right

Roof leak investigations for homes and businesses in Lower Assendon
On older houses, leaks often 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. We check parapets, valleys and flashings from every safe viewpoint. The findings are recorded with photos. If you’re worried about damp walls below an overflowing gutter and leaks that appear only in driving rain, a survey will tell you what’s going on, whatever the roof.
In a village or hamlet like Lower Assendon, older cottages and farmhouses often have roofs that have been patched over many years. A new leak may be fresh damage or the latest sign of long-term wear, which matters if you’re thinking of an insurance claim. The report says what was seen and what it points to. Damp in old walls and timbers is slow to dry, so the sooner the cause is found the better.
The report records the leaking roof as we found it on the day. It is useful right away, and a good reference for later, like when you want to compare after future work.

Useful tips for Lower Assendon property owners
From years of surveys, a few habits stand out as worth the effort:
- Mention earlier attempts to fix the leak
- Do not touch fittings that water is reaching
- Clear the loft hatch so we can get in
- Catch drips in a bucket and protect the floor
Where we find more than one possible route, we say which is most likely and why. Recommendations are prioritised by urgency where relevant, so you know what to deal with first.
Look at the roof from the ground after strong winds. Pieces of slate or tile in the garden mean something has moved. Small faults dealt with quickly rarely become leaks.
Rented homes, blocks and businesses
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out by urgency where it matters, which helps when budgeting.
We survey roofs for letting agents and landlords as well as householders. The report gives you a dated record of the leaking roof, with photographs, useful for planning maintenance.
What we look for on each type of roof
Valleys
Debris in a valley slows the water and pushes it sideways. During a downpour, water can back up under the coverings.
Chimney stacks
Water that gets in at the top can show up lower down. Open, unused pots let rain fall down the flue.
What happens on the day
Once we have finished looking, we write up our findings in a report with photographs. As for time on site, it normally takes about one to two hours on an ordinary house, and more on a big or complicated roof. In a small place like Lower Assendon, access is usually the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Before the survey
- Agree roof access with the managing agent if it is shared
- Show us where any leaks or stains appear
- If you are buying, let the agent know when we’re coming
How to book
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or use the contact form whenever suits you.

What a roof leak investigation looks like in Lower Assendon
With Greys Court about 1.6 miles south-west, Lower Assendon sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. 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.
Trees in and around Fawley Court and Temple Island shed leaves that can end up in nearby gutters, so outlets and downpipes are worth watching. If you let a flat or house near Henley-On-Thames station, a clear finding on where water gets in helps you brief a roofer straight away. If you look after a building like Rupert House School, tracing a leak on a big roof starts with where the water appears and works back.
