When to book a survey in Longwick
Many leaks begin at a flashing. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. Once that seal cracks or lifts, water gets behind it.
People usually book a survey when they’ve noticed something like this:
- Water dripping from rafters or underlay
- Leaks below a flat extension roof
- Leaks at a dormer or roof window
- Staining where a gutter or parapet meets the wall
If you own a rental within reach of Monks Risborough station, a clear finding on where water gets in helps you brief a roofer right away.
What to check before booking

How a roof leak investigation works in Longwick
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. We check each likely route and we follow where the evidence leads. Chimneys, dormers and roof lights each add joints of their own. Each one is looked at from wherever it’s safe to see it. If you’ve noticed stains around a skylight and staining around the chimney inside, we can find out what’s behind it, whatever the roof.
Around Longwick, chimneys on older homes are a common source of leaks, at the flashings, the pointing or the mortar round the pots. Damp in a chimney breast can have more than one cause, so it isn’t always obvious where it starts. The stack, its flashings and the loft space beside it are all worth checking.
What you get is a clear record of the leaking roof on the day we saw it. It is useful right away, and a good reference for later, such as when you want to compare after future work.

What you can safely check yourself
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in.

How the survey changes by roof type
Parapet and box gutters
Linings, joints and outlets are inspected wherever it’s safe.
Valleys
Debris in a valley slows the water and pushes it sideways. In heavy rain, it can spill under the edges of the slates or tiles.
Longwick: your questions answered
Do you cover Longwick?
We do. Every survey there gets the same written report with photos.
Will you come out to Longwick?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Will you fix the leak as part of this?
A leak investigation finds and reports the likely source. The repair is not part of it. You get a report with photos showing where the water is getting in and what needs attention, which whoever carries out the work can follow.
What happens after the survey?
You’ll receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
How quickly is the report sent?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed, ready to forward.
Does this replace a RICS home survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
Will you photograph what you find?
Yes. Photographs are taken throughout the survey, and they go into the written report alongside our recommendations.
What a roof leak investigation does not cover
It’s a careful look at the leaking roof, not the whole story. The main limits are:
- Leaks that only appear in weather we can’t recreate
- Defects hidden under coverings or inside walls without opening up
- Putting the leak right

Wind, rain and roofs in Longwick
A number of Buckinghamshire villages keep thatched roofs on their older buildings. 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. England has around 10,000 conservation areas and about 500,000 listed buildings. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so the council is the place to ask.
The streets around a church like Owlswick Chapel are often among the oldest in a place, and if you own one of the older houses nearby, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks. Anyone responsible for a site like Longwick Church of England Combined School will know that on a building that size, finding the source of a drip means looking well beyond the stain.

Longwick’s nearest station is Monks Risborough station, roughly 1.3 miles east of the centre.

Why get it checked now?
Wet insulation doesn’t insulate well. A slow leak can soak it for months before a stain appears. Catching it early limits what has to be replaced. Tradespeople may need to travel further to a smaller place like Longwick, so it is useful to plan roof work rather than call someone out in a hurry. Knowing early gives you time to get the right people in.
A Basic Survey starts from £150, with VAT included. Standard is from £250 and Premium from £400, both including VAT. You will know the price for the job before booking.

What we do, step by step
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect an hour or two for a house, with bigger or more complicated roofs taking longer. Homes around Longwick often have gardens on more than one side, which gives us room to step back and see the roof. Let us know if any side is fenced off or hard to reach. The loft, where there is safe access, completes the picture.
- We start with what you’ve seen: where the stain is and when it gets worse.
- The visit starts indoors, at the stain and in the loft.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- Moisture readings and thermal imaging are used where they help.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Before the survey
- Leave a clear route to the loft
- Have keys ready for side gates, garages or roof access doors
- Note where any stains or damp appear
