About our roof leak investigation in Cow Roast
On a flat roof, water can travel a long way under the covering. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Standing water puts extra pressure on every weak point. We check both the covering and the room underneath to narrow it down. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt often lasts around 15 to 20 years, so age is part of the picture. We are often asked to look into damp underlay across a wide area and wet patches on loft insulation, on chimney stacks, lead flashings and rooflights and dormers.
Somewhere as small as Cow Roast, older roofs have often been repaired many times. That makes it hard to tell new damage from old wear, which matters if you’re thinking of an insurance claim. We look at everything that’s safely in view and set out what we find. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
The report records the leaking roof as we found it on the day. That makes it useful now and a handy reference later, for instance when you want to check whether anything has changed.

What a roof leak investigation looks like in Cow Roast
About 2.7 miles south-west lies Cholesbury Manor House, a reminder of how long the area around Cow Roast has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Knowing the roof type helps narrow down where water may be getting in.
If you live in an older home near Church of St Bartholomew (church of England), leaks on older roofs often start at lead flashings, valleys or around old chimney stacks. If you let a flat or house near Tring station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. Trees in and around Tring Park shed leaves that can end up in nearby gutters, so outlets and downpipes are worth watching.

How we price roof leak investigations
Prices always include VAT. The things that change the price are:
- Whether thermal imaging or a drone is needed
- Roof area
- Chimneys, valleys, parapets and other details
- House, block, shop or office
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all inc. VAT. The roof’s size, height and access matter as well.
Helping us price your survey
There’s no need for technical words. It is enough to tell us:
- Access details, such as a loft hatch or a shared roof
- Any photos you have, taken from the ground or a window
- Where any leaks, stains or damp patches show inside
- The address and postcode of the property
If you have photos of the roof, send them over. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, phone 07833 053749 or use the contact form.
When you need someone else
A survey is a careful look at the leaking roof, but it cannot do everything. Its limits include:
- Carrying out the fix
- Faults hidden behind ceilings or boarding
- Leaks from plumbing, tanks or pipework rather than the roof
If you are not sure which survey you need, phone 07833 053749 or use the contact form and we will give you a straight answer before booking. What a survey covers and does not.
Roof types and parts we check
- Lead flashings
- Valleys and parapet gutters

Why act early in Cow Roast
Patching the spot above the stain often doesn’t work. The real way in may be a metre or more away. An investigation finds the likely cause first, so the repair is aimed at the right place. In a place like Cow Roast, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.

How it works
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take an hour or two at a typical home, or half a day or so for a commercial building. Older roofs in small places like Cow Roast can have low, tight loft spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it’s safe.
- We start with what you’ve seen: where the stain is and when it gets worse.
- Inside, we check the damp area and the loft space above it.
- Outside, we look at every likely route in.
- We use moisture detection, and thermal imaging where it is useful.
- We email a report with photos, the likely entry point and recommendations.
Preparing for the visit
- Have keys ready for side gates, garages or roof access doors
- Make a note of anything you’d like us to look at
- Mention any parking restrictions on your street

Roof by roof
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.
Chimney stacks
Our chimney check is a visual inspection of the stack, and it is not a flue or gas safety check.
