Roof Leak Investigation in Carterton
Find out the condition of the leaking roof at your property in Carterton. Visits run on weekdays and weekends, in the daytime.
- Ceiling stains that grow after rain
- Staining where a gutter or parapet meets the wall
- Water coming in around a roof light or dormer
Should I look at the roof myself first?
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in, using safe viewpoints and a drone where applicable.
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry and it will help the survey.
Roof leak investigation in Carterton: what you get
The aim is to find where the water is getting in and explain it. The report shows, with photos, where we believe the water gets in and how it travels, and recommends what should be done. Whoever does the work then has a clear starting point. We find and report the source, and the repair itself is a separate job. Common reasons to book are wet patches on loft insulation and damp walls below an overflowing gutter, on the roof space, flat roof details and lead flashings.
In a town like Carterton, older houses and newer estates leak in different ways. Older roofs suffer slipped slates, worn mortar and tired lead, while later houses can leak at valleys, verges and flat-roofed additions. Knowing the cause tells you what to do next. It also helps show whether the problem is long-standing wear or recent damage.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Different roofs, different checks
Lead flashings
Lead flashings seal the joints at chimneys, walls and dormers. We check for lead that has lifted, split or slipped, and for flashings that have been patched with bitumen.
Slate and tile slopes
Ridge and hip tiles can loosen as their mortar cracks. Water then gets in along the top of the roof.

How the survey works
It is useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take about 1–2 hours, more where the leak is intermittent or the roof is large. A visit in Carterton runs most smoothly with the loft hatch clear, side gates open and a parking spot in mind. Someone needs to let us in, so tell us who that will be.
- We help you choose the package that suits the leak.
- 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.
- You get photos, the likely cause and clear recommendations.
How to prepare
- Have any questions written down, so nothing gets missed
- Point out any leaks or damp patches
- Clear the way to the loft hatch

Carterton: your questions answered
How do I find out if my home in Carterton is listed?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
How should I get ready for a visit in Carterton?
Mostly, it is about access: the loft hatch, any locked gates and where to park in Carterton. Let us know about known leaks or past repairs as well.
Which days do you carry out surveys?
Visits run seven days a week in the daytime. Just say which days work for you.
Could my leak actually be condensation?
The two can look alike. Widespread damp on the underside of the roof in cold weather, with blocked vents, suggests condensation. We look at the pattern, take moisture readings and tell you which is more likely.
What should I do before you arrive?
Note when the leak appears and what the weather was doing, and take photos. Move stored items away from the loft hatch. Keep away from any light or socket that water is reaching.
What does the report include?
A report with photos, explaining the condition of the leaking roof, any defects and our recommendations, with the most urgent first where relevant. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where applicable and structural analysis.
Will you check the loft?
Usually, if there’s one and it can be reached safely. From inside, the underside of the roof often shows damp, staining or daylight that can’t be seen from outside.
Roof leak investigations around Carterton
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Different coverings let water in at different points, which shapes where the search starts. About 3.5 miles north-east lies Minster Lovell Hall, a reminder of how long the area around Carterton has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
For site and facilities teams at buildings like Carterton Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. If you own one of the older houses in the streets near St John the Evangelist, old mortar, worn lead and slipped slates are the usual suspects when water gets in.

Tips from our surveys
A survey works best with a little help from you, before and after. Some tips:
- Keep water away from lights and sockets
- Stay off ladders and the roof
- Take dated photos of the leak
- Write down the wind direction and rain when it leaks
If the leak turns out to be condensation, the report says so, with recommendations on ventilation. It saves chasing a leak that is not there.
Keep gutters, valleys and outlets clear, particularly in autumn. Many leaks start with a blocked outlet. Leave the clearing to someone with the right equipment.
What happens if roof problems are left?
A leak that returns after a repair typically means the real source wasn’t found. A careful investigation looks at every likely route, not just the obvious one. It gives the next repair a far better chance. Extensions and dormers on homes around Carterton often hide the first signs of trouble at their joints with the main roof. A few wet winters later, it can mean new plaster and decorating as well as roof work.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Roof leak investigation starts from £150, including VAT.
