Longcot Roof Leak Investigation
A careful look at the leaking roof at your property in Longcot, with photographs and a written report.
- Damp on a chimney breast
- Damp underlay across a wide area
- Leaks below a flat extension roof
What happens if roof problems are left?
Water damage grows the longer it’s left. Wet timbers start to decay, plaster softens and insulation stops working. Finding the source early keeps the damage down. Older cottages and farmhouses around Longcot can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.
Every price we give includes VAT. Roof leak investigation starts from £150, including VAT. You will know the price for your survey before you book.
What you get with us
- Professional indemnity and public liability insurance

Roof leak investigation in Longcot: what you get
We investigate roof leaks in Longcot and across London and South East England. We visit on weekdays, Saturdays and Sundays. The investigation covers inside and out, from the stain to the likely entry points. You get a photo-illustrated written report and recommendations. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, then phone 07833 053749 or drop us an email. Typical surveys look at brown rings on upstairs ceilings and damp on a chimney breast, across rooflights and dormers, flat roof details and valleys and parapet gutters.
For a small place like Longcot, the inspection is the same as anywhere: the journey and access are just planned ahead of time. Let us know where the water shows, when it appears and anything you’ve noticed outside, along with any repairs done before. If you have photos of the water coming in, they help as well.
Every survey ends with a written report, with photos, emailed to you. It explains the condition of the leaking roof, the defects we found and what we recommend.

Common questions in Longcot
How do I find out if my home in Longcot is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is Longcot in the area you cover?
Yes, Longcot is within the area we cover. We work right across London and South East England. Just phone 07833 053749 or drop us an email and let us know about the property, and we will talk through which survey suits.
Is thermal imaging part of a leak investigation?
Where conditions suit, it can. It works best after a sunny day, with a dry roof surface and little wind. Damp areas can hold heat differently from dry ones. Its findings are confirmed with a moisture check.
Does the investigation include the repair?
The investigation is about finding the cause. The repair isn’t part of it. You get a report with photos showing where the water is getting in and what needs attention.
How do I book a survey in Longcot?
It’s easiest to ring 07833 053749 or send us an email. Tell us the address and a little about the roof, and we’ll recommend the right survey. Surveys run on weekdays and at weekends.
Can you survey at the weekend?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
Will you fly a drone over my roof?
Where it is applicable and safe, yes. We are a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. It is included in the Drone Roof Survey and, where applicable, the Premium Survey.

Tips from our surveys
A survey works best with a little help from you, before and after. Some tips:
- Move stored items away from the hatch
- Write down the wind direction and rain when it leaks
- Catch drips in a bucket and protect the floor
- Photograph the stain each time it appears
The report gives whoever carries out the work a clear starting point. They’ll see exactly where the problem is, rather than at the stain.
Do not block the vents at the eaves. Air movement keeps condensation down, and condensation is a common false alarm. Check insulation does not block airflow at the eaves.
What a roof leak investigation looks like in Longcot
Buscot Park, about 4.1 miles north-west, is one of the historic houses in the wider area around Longcot. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. 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. Each of these roof types has its own typical places for water to get in.
If you look after a building like Longcot and Fernham Church of England Primary School, on a building that size, finding the source of a drip means looking well beyond the stain.

Around Longcot

What we do, step by step
We look at the roof from outside and, where it is relevant and there is safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey normally takes an hour or two, more where the leak is intermittent or the roof is large. Somewhere as small as Longcot, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- You let us know where the water shows and when it appears.
- Inside, we check the damp area and the roof space above it.
- Outside, we check every likely route in.
- Where it helps, we take moisture readings and use thermal imaging.
- You receive a written report with photos showing the likely source and what needs attention.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Leave a clear route to the loft
- Tell us where we can park nearby

When to book a survey in Longcot
Flat roofs fail with age and wear. A felt roof often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Upstands and outlets are common weak points.
It is worth booking a survey if you’ve seen:
- Wet patches on loft insulation
- Damp underlay across a wide area
- Water marks that spread in wet weather
- Staining around the chimney inside
For an older house near a landmark like Church of St Mary, the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Questions to ask before you book
- Whether VAT is added on top
- How much experience they have with roofs like yours
- What insurance they carry
- What the report includes, and whether it has photos
What affects the cost of roof leak investigations
A few things affect what a survey costs:
- The shape of the roof and its details
- Extensions, dormers and garages with roofs of their own
- House, block, shop or office
- If the survey needs thermal imaging or a drone
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
What to let us know when you contact us
To price your survey accurately, we will ask about:
- What’s prompted the survey
- Pictures from the garden or a window, if you have them
- Whether there is a loft hatch, a shared roof or tricky access
- Where any leaks, stains or damp patches show inside
Photos help, if you have them. Take them safely from ground level or a window. To get started, ring 07833 053749 or drop us an email.
