How a thermal roof survey works in Appspond
Thermal imaging is a useful tool, but it has limits. Sun, shade, reflective surfaces and wind can all change what the camera shows. We back up the images with moisture readings and a careful look at the roof. The report is clear about what the images show and what they don’t. Where something can’t be confirmed, we say what would help next. We survey ceilings below the roof, loft conversions and commercial roofs, and people most frequently book us about damp around roof outlets and upstands and damp where roofs meet walls and chimneys.
Some older homes in villages like Appspond are listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, which suits a building where any change needs care. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
What you get is a clear record of the roof on the day we saw it. It is useful straight away, and a good reference for later, for instance when you want to check whether anything has changed.

Airspace, weather and Appspond roofs
If your survey includes the drone, we check the Drone Safety Map for restrictions before flying. 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. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail.
For businesses in and around places such as Village Arcade St Albans, thermal images can show trapped moisture across a wide commercial roof. High Elms Manor, about 2.5 miles south, is one of the historic houses in the wider area around Appspond. Photos from the air and thermal images let an old roof be checked without anyone disturbing it.

Your questions about thermal roof surveys in Appspond
Will you come out to Appspond?
Yes, Appspond is covered. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
Does a conservation area affect roof work in Appspond?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
How long have you been surveying roofs?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys across London and the South East.
Do you use drones?
Yes, where it applies and safe. We fly a sub-250g drone and we are a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where it applies.
Does someone need to be in?
Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photographs. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Does the weather affect a thermal survey?
The weather makes a real difference. A sunny day beforehand, a dry surface and calm air all help. Rain and strong wind can make the images less clear, so we talk through the forecast when booking.
How the survey works
We don’t take risks to get a closer look. We inspect whatever is safely visible, and if part of the roof can’t be seen, the report says so. Most visits take between one and two hours on an ordinary house, while a commercial roof takes nearer three to four hours. Somewhere as small as Appspond, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- We carry out a visual inspection of the roof from wherever it can safely be seen.
- Thermal images are taken to show differences in surface temperature.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- You get a report with thermal images, photos and our recommendations.
How to prepare
- Have any questions written down, so nothing gets missed
- Buyers: confirm access with the estate agent or seller
- Agree roof access with the managing agent if it’s shared

Practical tips
A survey works best with a little help from you, before and after. Some tips:
- Move stored items away from the loft hatch
- Heat the home normally on the days before
- Keep the report to compare against after any repair
- Check outlets after heavy rain
Where a pattern can’t be confirmed, the report says what could help, such as electronic leak detection or opening up a small area.
Consider a repeat survey after major work on the roof in suitable weather.

Do you need a thermal roof survey in Appspond?
Some defects simply can’t be seen with the eye. Trapped moisture, missing insulation and hidden heat loss are three examples. A thermal camera adds another way of finding them.
Here are some of the things we see often:
- Thin or uneven insulation in the roof
- Damp where roofs meet walls and chimneys
- Ceilings that feel colder in places
- Damp around roof outlets and upstands
For site and facilities teams at buildings such as Marlborough Science Academy, a view from above covers a wide roof far faster than walking it.
Questions to ask before booking
- Whether any drone flown is registered with the CAA
- Is VAT included in the price?
- When you’ll get the report
- Which viewpoints they use to see the roof
What affects the price in Appspond
When we price a survey, we consider:
- The height of the building and how the roof can safely be seen
- The roof’s overall size
- Commercial roofs and larger buildings
- Any need for thermal images or a drone flight
A Basic Survey starts from £150, with VAT included. The Standard Survey starts from £250 and the Premium Survey from £400, both inc. VAT. We confirm the price for your roof before you book.
Booking your survey
When you call or email, these details help:
- The property’s address and postcode
- How the loft is reached, if there is one
- When you need the report by
- Pictures of the roof from a safe spot, if you have them
Our price is from £400, including VAT. The exact figure depends on the roof and the package, so ring 07833 053749 or send us an email with the details.
DIY checks: what’s safe
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, using safe viewpoints and a drone where applicable.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
