Ambrosden roofs and the weather
Boarstall Tower, about 3.5 miles south, is one of the historic houses in the wider area around Ambrosden. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Cotswold stone slates are found on older buildings in west Oxfordshire, and thatch survives in some of the county’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Different coverings let water in at different points, which shapes where the search starts.
If you let a flat or house near Bicester Village station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. If you live in an older home near Church of St Mary the Virgin, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
Ambrosden is about 3 miles south-east of Bicester, in Oxfordshire. Ambrosden gets the same service as everywhere else we work: a careful inspection, photos and a written report. Ambrosden is one of the towns and villages in Oxfordshire where we work. We also survey roofs in Oxford.

Roof leak investigations for homes and businesses in Ambrosden
Roof leaks rarely show up where you’d expect. It can run along a rafter, a batten or the underlay before it drips, so the stain on your ceiling is seldom right under the hole. We follow it back towards where it starts, 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. If you are worried about wet patches on loft insulation and water marks that spread in wet weather, a survey will tell you what’s going on, on slate and tile slopes, lead flashings and rooflights and dormers alike.
In older homes around places like Ambrosden, 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. In the loft, damp battens or wet insulation are often the first clues.
Nothing in the report is left vague: where something needs attention, it says so plainly, along with how urgent it is.

What we are asked to look at in Ambrosden
Many leaks begin at a flashing. Lead or mortar closes the gap wherever a roof meets a wall, chimney or dormer. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in, frequently well away from where it shows.
Typical things we are asked to look at include:
- Damp underlay across a wide area
- Leaks below a flat extension roof
- Damp walls below an overflowing gutter
- Drips in the loft during heavy rain
Take a building like Five Acres Primary School: tracing a leak on a big roof starts with where the water appears and works back.

What you can safely check yourself
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.

What we do, step by step
When we arrive, we start by asking what you’ve noticed and what you need to know. We then inspect everything that can safely be seen, from the ground, from windows, in the loft space and by drone where applicable. Most surveys take an hour or two, more where the leak is intermittent or the roof is large. Some parts of a survey depend on the weather, so a visit to Ambrosden is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- You get in touch with details of the leak and any photos.
- The visit starts indoors, at the stain and in the loft.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- Where it helps, we take moisture readings and use thermal imaging.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Preparing for the visit
- Agree roof access with the managing agent if it’s shared
- Check pets are kept safely away
- Leave side gates unlocked

Questions from Ambrosden
Is Ambrosden within the area you cover?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Do you carry out roof surveys in Ambrosden?
Yes. We cover the whole of London and South East England, and Ambrosden is part of that. Just call 07833 053749 or send us an email and let us know about the property.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning, with the building owner or managing agent. Mention it when you get in touch and we’ll explain what’s needed.
Do you need to get into the loft?
Yes, where the survey calls for it and there’s safe access. Inside, we look for damp, staining, gaps and sagging.
Do you climb onto every roof?
Only when it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and the report notes anything we couldn’t see.
Can you inspect my roof with a drone?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We are a CAA-registered drone operator.
How the survey changes by roof type
Lead flashings
Some roofs have mortar where you’d expect lead. They crack as the roof and wall move, letting rain run behind the joint.
Flat roof upstands and outlets
Outlets drain a flat roof. A blocked outlet leaves water standing, which tests every joint. We check outlets and the covering around them.
What a roof leak investigation does not cover
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- A promise to find every leak on a single visit
- Putting the leak right
- A structural engineer’s report

What happens if roof problems are left?
A leak that returns after a repair normally means the real source wasn’t found. A careful investigation looks at every likely route, not just the obvious one. That is frequently what breaks the cycle. Blocked gutters on homes around Ambrosden overflow and soak walls, especially where trees overhang. It’s easy to sort the cause early and slow to dry a damp wall.
