Swerford Roof Leak Investigation
Tracing where water is getting into your roof in Swerford. More than 5,000 surveys completed across London and South East England.
- Damp underlay across a wide area
- Stains around a skylight
- A leak that comes and goes with the weather
Different roofs, different checks
Valleys
A valley takes the rain from both sides of the roof. Worn or split linings and slipped valley tiles let it under the coverings.
Lead flashings
Lead flashings seal the joints at chimneys, walls and dormers. Lifted, split or slipped lead is a common cause, and for flashings that have been patched with bitumen.
Roof leak investigation in Swerford
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that don’t drain. Ponding water makes any weakness worse. We look at the roof surface and the ceiling below to narrow it down. Leaks under flat extension, garage and dormer roofs are common. Felt often lasts around 15 to 20 years, so age is part of the picture. Common reasons to book are drips in the loft during heavy rain and water coming in around a roof light or dormer, across slate and tile slopes, chimney stacks and the roof space.
In a village or hamlet like Swerford, 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, which matters if you are thinking of an insurance claim. The report says what was seen and what it points to. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
You receive the findings by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Swerford roofs and the weather
West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. The covering and its details give the first clues when tracing where water is coming from. If your home is older, it’s worth knowing whether it is listed or in a conservation area before planning roof work. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area.
In and around Swerford, as anywhere, a roof is easiest to deal with when its problems are found early.
Swerford is about 7 miles south-west of Banbury, in Oxfordshire. From houses to flats and shops in Swerford, we can survey the roof on a weekday or at the weekend. Swerford is one of the towns and villages in Oxfordshire where we work. You can also see our page for Oxford.
We cover every part of OX7 for roof leak investigations and the streets around it. Streets in the area include Chapel Hill and St Mary's Lane, all of which we cover. We also cover the places around Swerford: Wigginton (1 mile north-east), Little Tew (2 miles south), Great Tew (2 miles south-east), Hook Norton (2 miles north-west) and South Newington (2 miles north-east). Larger places within reach include Banbury (7 miles north-east), Bicester (14 miles south-east), Witney (13 miles south), Kidlington (13 miles south-east), Bure Park (13 miles east) and Chipping Norton (5 miles south-west).
Around Swerford
Typical jobs here are in homes near The Boxing Hare pub. Nearby you will also find Old Forge Museum (Great Tew) (1.6 miles south-east). Green spaces nearby include Woodford Bottom and Lamb's Pool.
Tips that help
Here are a few things we’d tell any owner, before and after a survey:
- Catch drips in a bucket and protect the floor
- Do not climb onto the roof to look
- Keep water away from lights and sockets
- Mention earlier attempts to fix the leak
With the Standard Survey you get a follow-up consultation, and Premium includes an in-person consultation. You can ask us about anything that is not clear.
Do not block the vents at the eaves. Air movement keeps condensation down, which is frequently mistaken for a leak. Keep insulation clear of the eaves.
What this survey cannot tell you
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Water from pipes, tanks or heating systems
- The repair itself (the investigation finds and reports the cause)
- Whether rotten timbers meet design loads
If you’re not sure which survey you need, call 07833 053749 or use the contact form and we’ll give you a straight answer before booking. What our survey covers.
What this survey covers
- Lead flashings
- The roof space
- Chimney stacks
- Rooflights and dormers
- Valleys and parapet gutters
- Flat roof details
- Slate and tile slopes
How it works
The visit has one job: to see as much of the leaking roof as can be seen safely and record it clearly. Notes and photos go into the written report. It usually takes about 1–2 hours for most homes, though a hard-to-trace leak can take longer. In a hamlet or village like Swerford, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- You get in touch with details of the leak and any photos.
- We look at the stain, the ceiling and the loft above it.
- Likely entry points outside are looked at, from flashings and valleys to gutters and outlets.
- We use moisture detection, and thermal imaging where it is useful.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Before the survey
- If the roof is shared, arrange access with whoever manages the building
- Point out any leaks or damp patches
- Make sure pets are kept safely away
Booking a survey
Our phone lines are open seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or email us.

Signs you need a roof leak investigation in Swerford
Valleys carry a lot of water. Worn lead, cracked linings or a build-up of leaves and moss can send that water under the coverings. The stain may appear well away from the valley itself.
Common reasons to book include:
- Water dripping from rafters or underlay
- Damp walls below an overflowing gutter
- Drips from nail tips in a cold loft
- Stains around a skylight
Take an older house close to Church of St Mary: leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.
Choosing a roof surveyor
- Their insurance cover
- Will they check the loft as well as the outside?
- What the report includes, and whether it has photos

Swerford questions
Do you cover smaller places like Swerford?
Yes, we do. Our area covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it’s useful to know about access.
Do you carry out roof surveys in Swerford?
Yes, Swerford is one of the places we work. Every survey there gets the same written report with photographs.
Why is the stain in a different place from the leak?
Because water travels. It can follow a timber or the underlay a long way first, so the entry point is frequently well away from the mark. We follow the route back instead of guessing.
Can you give me structural calculations?
No. We are experienced roof surveyors, and visible signs such as sagging are noted, but we don’t provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Does the report include photographs?
Yes. Photos are part of every report, so you can see each point for yourself.
Will you walk on the roof?
Only where it’s safe to do so. We check everything that can safely be seen: from ground level, from windows, from inside the loft space, from the roof where it’s safe and by drone where applicable. Anything we can’t see is noted in the report.
How long will you be at the property?
The visit normally takes an hour or two at a typical home, and longer for a large or complex roof. We’ll give you an idea of timing when you book.
Can I check my roof myself?
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.
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.
