Why act early in Sarratt
The longer moisture sits in a roof, the more it can affect timbers and finishes below. Surveying sooner gives you more choice about what to do. Outbuildings and barns around Sarratt are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
Every price we give includes VAT. Thermal roof survey starts from £400, including VAT. We confirm the price for the job before booking.

About our thermal roof survey in Sarratt
A thermal survey can point to places where heat is escaping through the roof. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it’s warm inside and cold outside. Our report points out what the images suggest and where to look more closely. It isn’t an energy rating or a heat loss calculation. We survey commercial roofs, ceilings below the roof and flat roofs, and people most often book us about areas of a flat roof that may hold water and leaks far from where the stain appears.
In a small place like Sarratt, open ground can mean strong wind. A small drone can’t fly safely in strong wind or heavy rain, and thermal imaging works best with little wind. The visit is planned around the forecast, along with the journey and access. A change in the forecast can mean moving the visit to another day.
Findings are set out part by part, from the coverings down to the gutters. It records what’s sound as well as what is not.

Tips from our surveys
Over many surveys, some simple habits stand out as worth the effort:
- Check from the ground or a window, never by climbing
- Talk to us about the weather when booking
- Heat the home normally on the days before
- Photograph damp patches with the date
Premium Surveys include an in-person consultation, giving you the chance to talk through the images and findings. There is a 12-month follow-up too.
Have small defects in the covering fixed early. Once water gets under a membrane, it can travel far before it appears inside.
What happens on the day
The visit has one job: to look at the roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit usually takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Rural addresses near Sarratt can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- The roof is inspected visually from safe viewpoints.
- A thermal camera records how the surface temperature varies across the roof.
- We check the patterns that stand out with moisture readings where there’s safe access.
- The report sets out the images, what they suggest and what we recommend.
Preparing for the visit
- Let us know where we can park nearby
- Make sure pets are kept safely away
- Have any questions written down, so nothing gets missed
Booking a survey
Most bookings start with a short call: phone 07833 053749 or drop us an email and we will ask a few questions about the roof. The price is agreed before a date is set.

Common roof problems in Sarratt
People often book a thermal survey when a damp patch has no obvious cause. A leak may start well away from where the stain appears. Temperature patterns can help narrow down where to look.
Problems we come across often include:
- Water that travels before it shows
- Damp around chimneys and parapets
- Cold areas below the roof
- Areas losing heat at the eaves and junctions
Chenies Manor House lies about 1.8 miles west, so building around Sarratt goes back a long way. For older roofs nearby, a look by drone or thermal camera is a hands-off way to check condition.
Questions to ask before booking
- What they will not be able to tell you
- Which parts of the roof they’ll actually see
- What insurance they carry
- How long the report takes to arrive
What a survey costs
What a survey costs depends on the time and equipment it needs. That comes down to:
- Whether thermal imaging or a drone is needed
- The package you choose: Basic, Standard or Premium
- The type of building, from a house to a block or an office
- Extensions, dormers and garages with roofs of their own
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.
What we need to know
Here’s what helps us most when you get in touch:
- What’s prompted the survey
- How the loft is reached, if there is one
- Dates you are working to, like exchange
- Your postcode, so we can check access and travel
When you’re ready to go ahead, call 07833 053749 or drop us an email. We will suggest a package, agree the price and find a date.

Sarratt: your questions answered
Do you cover smaller places like Sarratt?
Yes, Sarratt is covered. Our area covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it’s useful to know about access.
How do I find out if my home in Sarratt 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. 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.
What do I do with the report?
We email you the written report with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Will the survey show heat loss through my roof?
The camera can point to heat loss and gaps in insulation. We don’t give energy ratings or heat loss calculations, but the report shows where to look more closely.
Is thermal imaging included in your surveys?
It’s part of the Premium Survey, from £400. You also get an in-person consultation and a 12-month follow-up. Larger commercial roofs are quoted for their size.
What’s the best way to book?
Simply ring 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day.
What conditions are best for thermal imaging?
Conditions on the day have a big effect on what the camera can show. A dry surface, little wind and a sunny spell beforehand help most. We record the conditions in the report, so you know how much weight to give the images.
Thermal roof surveys around Sarratt
If the drone is used for your survey, the flight is checked against the Drone Safety Map first. 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. Older coverings on steep or tall roofs are hard to judge from below, so close-up aerial photos and thermal images help.
If yours is one of the older homes in the streets near Church of the Holy Cross, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement. Take a building like Sarratt Church of England Primary School: a view from above covers a wide roof far faster than walking it.
