Your questions about roof leak investigations in Lewknor
Is my home in Lewknor listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Do you carry out roof surveys in Lewknor?
Yes, Lewknor is one of the places we work. The survey and report are the same in Lewknor as anywhere else.
Can you inspect my roof with a drone?
Where it is applicable and safe, yes. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where applicable.
Do I have to be there for the survey?
Not always. If we only need the outside, we can agree that beforehand, but the loft and any rooms with damp need someone to let us in.
Will I get photos?
Yes, every report has them. Pictures sit next to the findings they show, so you can see what we mean.
Is it a leak or condensation?
The two can look alike. Widespread damp on the underside of the roof in cold weather, with blocked vents, suggests condensation. We check the pattern of damp and the ventilation, then say which is most likely.
What should I do before you arrive?
Check the loft can be reached. Have any photos of the leak ready, plus details of past repairs. Keep catching drips and keep water away from electrics.
Roof leak investigation in Lewknor
Water is good at hiding where it gets in. 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. 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. We survey chimney stacks, valleys and parapet gutters and lead flashings, and common reasons people get in touch are wet patches on loft insulation and damp underlay across a wide area.
Being in a small place like Lewknor makes no difference to how a leak or storm damage is looked at: we simply plan the journey and access ahead. Let us know where the water shows, when it appears and anything you’ve noticed outside, plus any earlier repairs. If you have photographs of the water coming in, they help as well.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

What affects the price in Lewknor
Not every roof costs the same to survey, and it comes down to:
- Commercial roofs and larger buildings
- How complicated the roof is, with its valleys, chimneys and parapets
- Any need for thermal images or a drone flight
- Building height and the viewpoints available
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.
Getting in touch
Before you get in touch, it’s useful to have:
- Anything about access we should know
- What made you get in touch
- Any deadline, such as an exchange date
- Any photos you have, taken from ground level or a window
Once you know what you need, phone 07833 053749 or drop us an email. From there it is a case of choosing a package, agreeing the price and fixing a day.
Rented homes, blocks and businesses
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out with the most urgent first where relevant.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Bigger roofs take more time, so they’re priced to suit.
What we are asked to look at in Lewknor
Flashings are one of the commonest sources of roof leaks. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in, frequently well away from where it shows.
Most people get in touch when they’ve noticed one of these:
- Water that shows only in certain storms
- Ceiling stains that grow after rain
- Stains around a skylight
- Damp on a chimney breast
For an older house near a landmark such as Church of St Margaret, the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Before you book anyone
- Is there a chance to talk the report through?
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether you get a written report with photos
- Their report turnaround times
Roof by roof
Slate and tile slopes
Ridge and hip tiles can loosen as their mortar cracks. Water then gets in along the top of the roof.
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.
Leave it or get it looked at?
Wet insulation doesn’t insulate well. Insulation can soak up water quietly before anything shows below. Catching it early limits what has to be replaced. Around Lewknor, older homes often have old roof timbers, and water through a failed covering can rot timber if it is left.
Prices start from £150, including VAT. What you pay depends on the size and height of the roof, access and which survey you book.
Why book with us
- 5,000+ roofs surveyed
- Independent findings on the roof’s condition
- We hold a CAA Flyer ID and Operator ID
- Photos and a written report every time

What a roof leak investigation looks like in Lewknor
Adwell House, about 1.6 miles north-west, is one of the historic houses in the wider area around Lewknor. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. 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.
Anyone responsible for a site like Lewknor Church of England Primary School will know that a leak through a large roof is frequently found some distance from where the water shows inside.

What we do, step by step
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. A typical survey takes about 1–2 hours, more where the leak is intermittent or the roof is large. In a hamlet or village like Lewknor, 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. After that, the survey runs as it would anywhere.
- You get in touch with details of the leak and any photos.
- We look at the stain, the ceiling and the loft above it.
- Outside, we check every likely route in.
- We use moisture detection, and thermal imaging where it is useful.
- You receive a written report with photos showing the likely source and what needs attention.
Before the survey
- If the roof is shared, arrange access with whoever manages the building
- Find any records of previous roof work
- If it is not your property yet, arrange access through the agent
Booking a survey
Getting a price is simple: just call 07833 053749 or send us an email, let us know about the property and we will point you to the right survey. The price is agreed up front.
