How a roof leak investigation works in Sarratt
Our roof leak investigations cover Sarratt and the wider South East. We visit seven days a week. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. The findings come in a written report with photos. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, then phone 07833 053749 or use the contact form to arrange a visit. We survey chimney stacks, valleys and parapet gutters and the roof space, and people most often book us about water coming in around a roof light or dormer and wet patches on loft insulation.
In a village or hamlet like Sarratt, older cottages and farmhouses often have roofs that have been patched over many years. That makes it hard to tell new damage from old 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 is worth finding the cause soon.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that is said too.

What else we do in Sarratt
What affects the cost of roof leak investigations
A few things affect what a survey costs:
- The use of thermal imaging or a drone
- The size of the roof
- Height and safe access
- Whether it is a home or a commercial building
Every price we give includes VAT, and the written report is part of the package. Prices start from £150, including VAT. Where your roof sits in the range depends on its size, height and access.
Booking your survey
You don’t need to know any roofing terms. Just let us know:
- Photos of the roof, taken safely from ground level or a window
- How the loft is reached, if there is one
- What kind of property and roof it is
- Where the property is, with the postcode
Booking is simple: just phone 07833 053749 or send us an email, let us know about the property and we’ll suggest the right survey. The price is agreed up front.
Why it is worth a survey now in Sarratt
Wet insulation doesn’t insulate well. Insulation can soak up water quietly before anything shows below. The sooner the cause is found, the less needs replacing. Older cottages and farmhouses around Sarratt can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. Size, height and access can affect the price too.

What happens on the day
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. A typical survey takes between one and two hours for a house, or half a day or so for a commercial building. In a hamlet or village like Sarratt, a postcode does not always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We start with what you’ve seen: where the stain is and when it gets worse.
- We check the stain, the ceiling and the loft above it.
- Outside, we check every likely route in.
- 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.
How to prepare
- Tell us about any leaks, stains or damp patches you know of
- Leave a clear route to the loft
- Have any paperwork from past roof work to hand
How to book
If you are buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or drop us an email whenever suits you.
Advice
Your questions about roof leak investigations in Sarratt
Do you carry out roof surveys in Sarratt?
Yes. We work right across London and the South East, and Sarratt is part of that. You can call 07833 053749 or send us an email with the address and a few details.
Is my home in Sarratt listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a 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.
Will you walk on the roof?
Not unless it is safe. Safe viewpoints, the loft space and a drone where applicable cover most of what’s needed, and the report notes anything we couldn’t see.
Will you photograph what you find?
Yes. The report includes photos of what we found.
Do you use thermal imaging to find leaks?
We use thermal imaging where it helps, and it’s part of the Premium Survey. It picks up temperature patterns rather than water, so we confirm its findings with moisture readings.
Why doesn’t the damp patch line up with the hole?
Rain that gets in will run along whatever it lands on. On a flat roof it can travel under the covering before it shows. Following that route is what our investigation does.
Do I need to be at home?
Not necessarily. If we only need the outside, we can agree that in advance, but anything inside needs someone there to give access.
Signs you need a roof leak investigation in Sarratt
A gutter that overflows can soak a wall and mark the ceiling inside. Parapet and box gutters are the worst for this, since a blocked outlet sends water over the lining and into the building.
Look out for signs like these:
- Drips in the loft during heavy rain
- Water marks that spread in wet weather
- Stains around a skylight
- Leaks that appear only in driving rain
If you look after a building like Sarratt Church of England Primary School, tracing a leak on a big roof starts with where the water appears and works back.
Before you book any roof surveyor
- Will the report include photos?
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Is there a chance to talk the report through?
- Their drone registration, if they fly one
How the survey changes by roof type
Lead flashings
Some roofs have mortar where you’d expect lead. Fillets crack and pull away over time, letting rain run behind the joint.
Valleys
Stains from a valley leak often show some distance off. We trace the route from the loft where there is safe access.
What a roof leak investigation looks like in Sarratt
With Chenies Manor House about 1.8 miles west, Sarratt sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Knowing the roof type helps narrow down where water may be getting in.
Landlords with a home close to Chorleywood station may find that a tenant living with a leak needs the cause found, not just the stain painted over. The streets around a church like Church of the Holy Cross are often among the oldest in a place, and if your home is one of the older ones nearby, lead flashings, valleys and old chimneys are typical places for water to get in.
