Roof leak investigations for homes and businesses in Sandford St Martin
Leaks tend to begin where one part of a roof meets another. Common entry points include chimney and wall flashings, valleys, parapet and box gutters, and the upstands and outlets on flat roofs. We check each likely route and follow the evidence. Chimneys, dormers and roof lights each add joints of their own. We look at all of them, from every safe vantage point. If you’ve noticed water that shows only in certain storms and damp underlay across a wide area, we can find out what’s behind it, on flat roof details, rooflights and dormers and the roof space alike.
Many homes in small places like Sandford St Martin face open ground, where storms hit ridges, verges and chimneys hardest. Once water gets into older walls, it takes a long time to dry, which makes finding the cause quickly worthwhile. A written record also helps if you need to explain it to anyone else.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the leaking roof, the defects we found and what we recommend.

How it works
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes about one to two hours for most homes, though a hard-to-trace leak can take longer. Somewhere as small as Sandford St Martin, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the loft space, we trace the water’s route where there’s safe access.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Before the survey
- Have keys ready for side gates, garages or roof access doors
- Make a note of anything you’d like us to look at
- Move anything stored under the loft hatch
Arrange a survey
If you are buying, it helps to book soon after your offer is accepted, so there is time to use the report before exchange. For any other survey, just ring 07833 053749 or use the contact form when you’re ready.
Related advice
Rented homes, blocks and businesses
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work.
Roof by roof
Slate and tile slopes
Cracked mortar lets ridge and hip tiles move. Rain can then run in at the ridge.
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.
Tips that help
A survey works best with a little help from you, before and after. Some tips:
- Don’t climb onto the roof to look
- Mention earlier attempts to fix the leak
- Note the weather when the leak shows
- Catch drips in a bucket and protect the floor
With the Standard Survey you get a follow-up consultation, and Premium includes an in-person consultation. It’s a chance to ask about anything in the report.
Keep gutters, valleys and outlets clear, particularly in autumn. Many leaks start with a blocked outlet. Use a professional rather than climbing up yourself.

Sandford St Martin roofs and the weather
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. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. An older home may be listed, or stand in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. Re-roofing in different materials may need permission there.
Landlords with a home close to Heyford station may find that a clear finding on where water gets in helps you brief a roofer right away. If you live in an older home near Church of St Martin, water on an older roof tends to find its way in at the lead, the valleys or the chimney.

DIY checks: what’s safe
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
