How a thermal roof survey works in Trowley Bottom
A thermal survey isn’t a quick fix for every roof problem. It shows surface temperature, and things like sun, shade, reflections and wind all affect the readings. We back up the images with moisture readings and a careful look at the roof. Our report says plainly what the camera picked up and how sure we can be. Where something cannot be confirmed, we say what would help next. If you’re worried about areas losing heat at the eaves and junctions and ceilings that feel colder in places, we can find out what’s behind it, whatever the roof.
Somewhere as small as Trowley Bottom, older roofs are often steep and partly hidden by trees or outbuildings. Close-up drone photos and thermal images help show what can’t be reached safely. Both the forecast and the airspace are checked first, and the journey is planned in advance. Steep slopes and tall chimney stacks are where a close-up view adds the most.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

What we do, step by step
Safety comes first on every visit. We inspect whatever is safely visible, and anything we cannot see is noted in the report. Most visits take about one to two hours for most homes, plus time to check any thermal findings with moisture readings. In a small place like Trowley Bottom, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- You let us know about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Preparing for the visit

- Have any questions written down, so nothing gets missed
- Dig out any old roof reports or invoices

How we price thermal roof surveys
We confirm the price for the job before you book. This is what makes a difference:
- Any need for thermal images or a drone flight
- How tall the building is and how easy the roof is to see
- The roof’s overall size
- Which survey package you book
A Basic Survey starts from £150, with VAT included. Standard is from £250 and Premium from £400, both inc. VAT. You’ll know the exact price before booking.
What to let us know when you contact us
Here’s what helps us most when you get in touch:
- How the loft is reached, if there is one
- Why you want a survey: buying, a leak, a storm or new work
- Any photos you have, taken from the ground or a window
- Any stains, drips or damp patches you’ve seen indoors
When you are ready to go ahead, phone 07833 053749 or send us an email. We will suggest a package, agree the price and find a date.
Honest limits
Before booking, it is worth knowing what a survey won’t do:
- Readings unaffected by sun, shade or reflections
- Confirming water without moisture readings
- A structural engineer’s assessment
If in doubt, phone 07833 053749 or email us and we will recommend the right survey. What a survey covers and doesn’t.
What this survey covers
- Pitched roof slopes
- Commercial roofs
- Insulated roof spaces
- Flat roofs
- Loft conversions
- Ceilings below the roof
How the survey changes by roof type
Loft insulation
Loft insulation is easily disturbed when people store things or run cables. Thermal images can show where it has been pushed aside.
Pitched slate and tile roofs
Inside the loft space, thermal images can help with damp around stacks, valleys and roof windows. Findings are checked with moisture readings.
Your questions about thermal roof surveys in Trowley Bottom
How do I find out if my home in Trowley Bottom is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Is Trowley Bottom within the area you cover?
We do. A small place gets exactly the same survey as a big one.
What can thermal imaging tell me about my roof?
The images show how warm or cool each part of the surface is. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, and we check them with moisture readings.
Which days do you carry out surveys?
We carry out surveys on weekdays and at weekends. To arrange a date, ring 07833 053749 or send us an email.
How fast do I get the report?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
Will thermal imaging find my leak?
It is a useful tool for tracing leaks, but not the only one. The results depend on conditions on the day. If the source can’t be confirmed, we will say what could help next, such as electronic leak detection.
What’s the best way to book?
It’s easiest to ring 07833 053749 or email us. Let us know the address and a little about the roof, and we will recommend the right survey. We survey seven days a week.
Thermal roof surveys around Trowley Bottom
If your survey includes the drone, the flight is checked against the Drone Safety Map first. 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. Many roofs like these can’t be judged properly from the pavement, and that is where a view from above or a thermal image earns its place.
If your house is among the older ones in the streets near Church of St Leonard, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view from the air or with a thermal camera helps. For site and facilities teams at buildings such as Flamstead Village School, a view from above covers a wide roof far faster than walking it. With Childwickbury Manor about 4.5 miles south-east, the area around Trowley Bottom has a long history. Aerial photos and thermal images let an old roof be checked without anyone disturbing it.

For landlords and managing agents
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.
Landlords and agents in Trowley Bottom book surveys as well as householders. The report gives you a dated record of the roof, with photographs.
What you can safely check yourself
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey.
