Your questions about roof leak investigations in Middle Assendon
Is Middle Assendon in the area you cover?
Yes. We work right across London and South East England, and Middle Assendon is part of that. You can ring 07833 053749 or drop us an email with the address and some details.
Is Middle Assendon within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Just mention lanes, gates or anything else about the route when booking.
Will you walk on the roof?
Only if it is safe. We look at everything that can safely be seen: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where applicable. The report says if anything couldn’t be seen.
Why is the stain in a different place from the leak?
Water follows the easiest path, not the shortest. On a pitched roof it frequently runs down a rafter before it shows. Following that route is what our investigation does.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years, across London and South East England.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
About our roof leak investigation in Middle Assendon
The aim is to find where the water is getting in and explain it. You get a report with photographs showing the likely entry point and the route the water is taking, and recommends what should be done. Whoever does the work then has a clear starting point. We find and report the source, while the repair is a separate matter. If you’ve noticed staining around the chimney inside and brown rings on upstairs ceilings, we can find out what’s behind it.
Many homes in small places like Middle Assendon face open ground, so storms hit ridges, verges and chimneys hard. Once water gets into older walls, it takes a long time to dry, which makes finding the cause quickly worthwhile. A record with photographs is useful if you need to show the damage to anyone else.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Prices for roof leak investigations in Middle Assendon
Prices always include VAT. The things that change the price are:
- The size of the roof
- How many separate roofs there are, such as extensions, dormers and garages
- Whether you choose the Basic, Standard or Premium Survey
- The shape of the roof and its details
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Prices start from £150, including VAT.

Leaks and storm damage in Middle Assendon
About 1.8 miles south-west lies Greys Court, a reminder of how long the area around Middle Assendon has been built on. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, 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. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Each of these roof types has its own typical places for water to get in.
If you live in an older home near Church of St James, old mortar, worn lead and slipped slates are the usual suspects when water gets in. If you live near a park like Fawley Court and Temple Island, or anywhere with mature trees, autumn leaves can block gutters and valleys, and blocked gutters overflow and soak walls.

How the survey changes by roof type
Flat roof upstands and outlets
Flat roof water can travel under the covering before it shows. Where conditions allow, moisture readings and thermal imaging help narrow it down.
Lead flashings
Mortar fillets are sometimes used instead of lead. They crack as the roof and wall move, letting rain run behind the joint.
Do you need a roof leak investigation in Middle Assendon?
Chimneys can let water in by several routes. Eroded pointing, cracked flaunching, failed flashings and open pots can all be responsible. The damp may appear on a chimney breast, a ceiling or in the loft.
We’re often asked to look at:
- Water through the ceiling under a flat roof
- Damp patches next to the stack
- Leaks that appear only in driving rain
- Damp underlay across a wide area
For landlords with property near Henley-On-Thames station, tracing a leak quickly matters when a tenant is living with it.
Choosing a roof surveyor
- Whether VAT is added on top
- Are they insured for the work?
- Will the report include photos?
- How much experience they have with roofs like yours
Checking the roof from the ground
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
How it works
Photographs are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. A typical visit takes roughly 1–2 hours for a house, rising to roughly 3–4 hours on a commercial building. Older roofs in small places like Middle Assendon can have low, tight loft spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- You get in touch with details of the leak and any photos.
- Inside, we check the damp area and the loft space above it.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- Moisture readings and thermal imaging are used where they help.
- We email a report with photos, the likely entry point and recommendations.
How to prepare
- Keep pets out of the way during the survey
- Buyers: confirm access with the estate agent or seller
- Make sure the loft hatch can be reached
