Roof leak investigations around Charlton-on-Otmoor
With Boarstall Tower about 4 miles east, Charlton-on-Otmoor sits in an area with a long building history. 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 any change of roofing material on a listed home needs checking with the council first. West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Each of these roof types has its own typical places for water to get in.
The streets around a church such as Church of St Mary the Virgin are often among the oldest in a place, and if your home is one of the older ones nearby, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks. If you run a business near Bicester Avenue, a quick answer on where water is coming in keeps a business running. Take a building like Charlton-on-Otmoor Church of England Primary School: a leak through a large roof is frequently found some distance from where the water shows inside.

How a roof leak investigation works in Charlton-on-Otmoor
Moisture readings and thermal imaging are used where they’re useful. Moisture detection confirms where timbers, plaster or insulation are damp. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so we confirm what it suggests with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. Thermal imaging works best after a sunny day, on a dry roof with little wind. Common reasons to book are drips in the loft during heavy rain and water coming in around a roof light or dormer, across the roof space, valleys and parapet gutters and rooflights and dormers.
In a village or hamlet like Charlton-on-Otmoor, 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, and the difference matters, especially to an insurer. The report says what was seen and what it points to. Older walls and timbers hold water for a long time, so it is worth finding the cause soon.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Questions from Charlton-on-Otmoor
Do you carry out roof surveys in Charlton-on-Otmoor?
Yes. Our area covers London and the South East, and Charlton-on-Otmoor is part of that. Just phone 07833 053749 or use the contact form and tell us about the property.
How do I find out if my home in Charlton-on-Otmoor is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Is the repair included in the leak investigation?
The investigation is about finding the cause. The repair itself is a separate job. You get a report with photos showing where the water is getting in and what needs attention.
Are you insured?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Will I get photos?
Yes, plenty. Each finding is shown in a picture where possible, which makes the report easy to follow.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
How do you tell a leak from condensation?
Many apparent leaks turn out to be condensation. Leaks tend to follow wet weather and show in one place, while condensation is frequently widespread and worst on cold days. We tell you which it is most likely to be.
Why act early in Charlton-on-Otmoor
Water damage grows the longer it’s left. Damp spreads into rafters, ceilings and insulation. Tracing it now means less to put right later. Matching old materials, such as handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.

How we price roof leak investigations
A few things affect what a survey costs:
- The height of the building and how the roof can be seen safely
- Which survey package you book
- Whether it is a home or a commercial building
- The roof’s overall size
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. We’ll give you the figure before anything is booked.
What to let us know when you get in touch
The more you tell us, the easier it is to price the survey. When you contact us, let us know:
- Your postcode, so we can check access and travel
- Where water is showing inside, if it is
- The type of building and roof, such as pitched or flat
- What made you get in touch
If you are buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or email us when you’re ready.
What we do, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes between one and two hours for most houses, with bigger or more complicated roofs taking longer. You are welcome to ask questions while we’re there. Older rural homes like those around Charlton-on-Otmoor can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- The report explains the likely entry point and what needs attention.
How to prepare

- Unlock side gates and any roof access doors
- Mention any parking restrictions on your street

What else we do in Charlton-on-Otmoor
Should I look at the roof myself first?
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in.
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
Rented homes, blocks and businesses
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.
Businesses and commercial landlords can book us too. Bigger roofs take more time, so they’re priced to suit.
How the survey changes by roof type
Parapet and box gutters
We check the linings, joints and outlets where we can see them safely.
Valleys
A valley leak can appear well away from the valley inside. From inside the roof space, we follow the water’s route back.
