Thermal imaging roof survey in Fairfield, Hertfordshire
Wondering about the roof at a property in Fairfield? We carry out thermal roof surveys in Fairfield and across Hertfordshire, with plain-English findings.
- Wet insulation beneath the membrane
- Patches of heat loss across the roof
- Damp patches with no obvious cause
How a thermal roof survey works in Fairfield
On a flat roof, wet insulation holds heat longer than dry insulation. So a wet patch can show as a warmer or cooler area on the camera. This can give an idea of how far water has travelled beneath the membrane, something you can’t normally tell from the surface. Moisture readings are then used to check what the camera suggests. If you’ve noticed water getting in at parapets and stacks and damp around roof outlets and upstands, a survey will tell you what’s going on, whatever the roof.
In a small place like Fairfield, 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. If the day turns windy or wet, the visit can be moved.
Findings are set out part by part, from the coverings down to the gutters, each with a short note and a photograph. You’ll see the good as well as the bad.

Do you need a thermal roof survey in Fairfield?
After a repair, some owners want to know whether the roof has dried out. A thermal survey with moisture readings can show whether wet areas remain when the conditions on the day are suitable.
Typical things we are asked to look at include:
- Damp patches with no obvious cause
- Water that travels before it shows
- Patches of heat loss across the roof
- Wet areas near outlets and upstands
If you look after a building such as Fairfield Park Lower School, a view from above covers a wide roof far faster than walking it.
Questions to ask before booking
- Whether the inside of the roof is included
- Their report turnaround times
- What the survey will not cover
- Is there a chance to talk the report through?
Surveys for landlords and agents in Fairfield
We survey roofs for landlords and letting agents as well as householders. The report gives you a dated record of the roof, with photos, useful for planning maintenance.
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
What a thermal roof survey looks like in Fairfield
Where the drone is part of the survey, 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. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
Hinxworth Place, about 3.7 miles north-east, is one of the historic houses in the wider area around Fairfield. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings. Take an older house close to St Thomas' Church: older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help.
Fairfield is about 1 mile south-west of Stotfold, in Hertfordshire. Whether the building in Fairfield is a house, a flat or a commercial unit, we can survey the roof. Across Hertfordshire, we cover Fairfield. We also survey roofs in Milton Keynes.

What we look for on each type of roof
Parapets, valleys and junctions
Parapet and valley gutters can overflow inside a building. Thermal images, checked with moisture readings, can help trace it.
Pitched slate and tile roofs
Even on pitched roofs, the camera can point to heat loss and some damp. The report explains what the images can tell you and what they cannot.

What else we do in Fairfield
Fairfield: your questions answered
How do I find out if my home in Fairfield is listed?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is Fairfield within the area you cover?
Yes, Fairfield is covered. Our area covers London and the South East, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Will I get photos?
Yes. We photograph the roof as we go, and they go into the written report.
Can you check my loft insulation with a thermal camera?
It can show temperature patterns that point to missing or thin insulation. The difference is clearest when the building is heated and it is colder outside. Where we can reach the loft safely, we check there too.
Can you tell me if my roof has asbestos?
No. We don’t carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Can you do a thermal survey in any weather?
The results depend on the weather. Dry, calm weather after some sun gives the best chance of clear images. Our report notes the conditions and how they affected the findings.
Do you climb onto every roof?
Only when it’s safe. Safe viewpoints, the loft space and a drone where applicable cover most of what’s needed, and anything out of sight is recorded in the report.
What happens on the day
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. The survey itself takes about 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Older rural homes like those around Fairfield can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely.
- 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 be seen safely.
- We take thermal images of the roof to pick up temperature patterns.
- Any patterns of interest are checked with moisture readings where we can reach them.
- The report sets out the images, what they suggest and what we recommend.
How to prepare
- Have any questions written down, so nothing gets missed
- Have any paperwork from past roof work to hand
- Leave a clear route to the loft

What a thermal roof survey does not cover
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Readings unaffected by sun, shade or reflections
- Proving moisture from the images alone
- The condition of timbers we cannot see
If in doubt, phone 07833 053749 or send us an email and we’ll recommend the right survey before you book. The full list of what we check.
Roof types and parts we check
- Insulated roof spaces
- Ceilings below the roof
- Loft conversions
- Commercial roofs
- Flat roofs
- Pitched roof slopes
Leave it or get it looked at?
Before replacing a large flat roof, it helps to know how much of it is actually wet. Thermal imaging, checked with moisture readings, gives a clearer picture before you spend. Matching old materials, such as handmade tiles or stone slates, can take time to source. That’s one more reason to find defects before they become urgent.
A Basic Survey starts from £150, including VAT. The Standard Survey starts from £250 and the Premium Survey from £400, both including VAT. We confirm the exact price before booking.
