Thermal roof survey in Harefield
On a flat roof, wet insulation holds heat longer than dry insulation. That means a wet area can show up as a different temperature from the rest of the roof. It helps us see how far water may have spread under the covering, which is hard to judge by eye. We then check those areas with moisture readings. If you’re worried about stains that keep coming back and areas losing heat at the eaves and junctions, we can find out what’s behind it.
Around Harefield, lots of roofs are low enough to see partly from the garden or the street. Chimney tops, valleys and rear slopes are where close-up or thermal images help most. The forecast decides the day. Even so, a close-up image often shows wear on ridges and flashings that a view from ground level misses.
After the visit, you get a report with photos, emailed to you. It sets out the condition of the roof, any defects and our written recommendations.

Thermal roof surveys around Harefield
A number of Buckinghamshire villages keep thatched roofs on their older buildings. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. Historic houses such as Ickenham Hall, about 3.4 miles south-east, show how far back building in the area around Harefield goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Take an older house close to Harefield Baptist Church: thin or patchy insulation under an old roof often shows up clearly on a thermal image.

What we do, step by step
Every roof is different; as a rough guide, the survey takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. You are welcome to ask questions while we’re there. A visit to a smaller place like Harefield is no different on the day: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- 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.
How to prepare
- If you’re buying, let the agent know when we’re coming

Common roof problems in Harefield
Some defects simply cannot be seen with the eye. Wet insulation, gaps in insulation and heat loss are frequently invisible from outside. A thermal camera adds another way of finding them.
Common reasons to book include:
- Damp around chimneys and parapets
- Heat escaping through the roof
- Cold areas below the roof
- Wet areas near outlets and upstands
Take a building like Harefield Infant School: thermal images can show where wet insulation sits under a big flat roof.
What to check before booking
- Whether the loft space is looked at, where there is one
- What happens after the report arrives
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Is VAT included in the price?
Practical tips
A little preparation and a few simple habits help. Our tips:
- Take photos of stains as they appear, so we can compare
- Note where damp appears and after what weather
- Move stored items away from the loft hatch
- Check from ground level or a window, never by climbing
After the visit, we put the thermal images, photos and moisture readings into one report. Each image is explained in plain words, alongside what we recommend. Premium reports are sent the same day.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
FAQs for Harefield
Is Harefield within the area you cover?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Let us know about access, parking and anything unusual about getting there when you book.
Are there drone restrictions around Harefield?
The answer turns on the exact location and the conditions on the day. Denham Aerodrome is about 2 miles away, so we check the Drone Safety Map for restrictions before any flight. The flight also waits for calm, dry weather.
Will the survey show heat loss through my roof?
It can show temperature patterns that point to missing or thin insulation. The difference is clearest when the building is heated and it’s colder outside. We look from the loft as well, where there is safe access.
How long have you been surveying roofs?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and the South East.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Let us know which days suit you as you book.
What’s in the survey report?
Written findings with photos, explaining the condition of the roof, any defects and our recommendations. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where it applies and structural analysis.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
What this survey can’t tell you
To be straight with you, there are limits to any roof survey:
- Readings unaffected by sun, shade or reflections
- Confirming water without moisture readings
- Insulation values or heat loss calculations
