Thermal Roof Survey in Hatfield
Thermal imaging to find moisture and heat loss patterns in a roof in Hatfield, carried out by an experienced roof surveyor. Every survey comes with a written report and photographs.
- Water that travels before it shows
- Stains that keep coming back
- Ceilings that feel colder in places
Signs you need a thermal roof survey in Hatfield
Once a leak has been fixed, people often ask whether the roof is still wet. Thermal images and moisture readings can suggest whether moisture is still trapped, given suitable conditions on the day.
Most people get in touch after spotting one of these:
- Areas losing heat at the eaves and junctions
- Gaps in loft insulation
- Possible trapped moisture under a flat roof covering
- Stains that keep coming back
Historic houses such as Hatfield House, about 1 mile east, show how far back building around Hatfield goes. Photos from the air and thermal images let an old roof be checked without anyone disturbing it.

Thermal roof survey in Hatfield: what you get
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. It can show patterns that point to trapped moisture under the membrane. On pitched roofs, slates and tiles over a ventilated space can hide what’s below, so we combine the camera with an inspection from the loft where there’s safe access. If you are worried about stains that keep coming back and patches of heat loss across the roof, we can find out what’s behind it.
In older houses around Hatfield, loft insulation can be thin, patchy or missing in places. Thermal imaging can show where heat escapes, and it can also point to damp patches. It shows temperature, so anything that looks like moisture is checked with a meter, while drone photos show the outside of the same roof. Results depend on conditions, so the timing of the visit matters.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend.

FAQs for Hatfield
Do you cover Hatfield?
Yes. We work right across London and the South East, and Hatfield is part of that. Just phone 07833 053749 or use the contact form and let us know about the property.
What do I need to do before a survey in Hatfield?
It is useful to clear access to the loft, and to let us know about leaks, damp patches or recent work. Let us know about parking and access in Hatfield too.
Can thermal imaging show missing insulation?
The camera can point to heat loss and gaps in insulation. We don’t give energy ratings or heat loss calculations, but the images show where improvements may help.
How experienced are you?
We have completed more than 5,000 surveys, over more than 20 years.
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. Our report notes the conditions and how they affected the findings.
Is this a RICS survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
Which days do you carry out surveys?
We survey seven days a week: weekdays, Saturdays and Sundays. Tell us which days suit you when you book.
What happens if roof problems are left?
Repeated repairs that don’t stop a leak are a sign the source hasn’t been traced. Thermal imaging with moisture readings can help narrow it down, rather than more guesswork. On a house in a town like Hatfield, wet loft insulation stops working and can stay damp for a long time. That is an extra cost on top of the roof work itself.
Prices start from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, including VAT.

Thermal roof surveys in Hatfield: local notes
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail.
Hotels and guest houses near Hatfield cannot easily close rooms for a leak, so it pays to find faults before guests do. Take an older house close to Church of St Luke: older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help.

Landlord and commercial surveys in Hatfield
Where a roof is shared: we need access agreed with the freeholder or managing agent. Tell us about it when you book and we’ll plan the visit with that in mind.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out by urgency where it matters, which helps with budgets and planning.
Practical tips
Over many surveys, some simple habits stand out as worth the effort:
- Clear a path to the loft hatch before we arrive
- Clear leaves from outlets and gutters each autumn
- Talk to us about the weather when booking
- Photograph damp patches with the date
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it’s easy to find each area on the roof.
Watch for new damp patches on ceilings beneath the roof. Catching a leak early stops insulation getting soaked.
When you need someone else
Before you book, it is worth knowing what a survey won’t do:
- Seeing water directly, as the camera shows temperature, not moisture
- An energy rating for the building
- Clear results when the conditions on the day are poor

How the survey works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from each safe vantage point, take photos as we go and record our findings for the written report. It typically takes about 1–2 hours on an ordinary house, while a commercial roof takes nearer three to four hours. Parking in a town like Hatfield is normally simple, but tell us if there is a driveway or any restrictions. We check the roof from ground level and from windows, then from the loft where there is safe access.
- You tell us about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- We back up the thermal patterns with moisture readings.
- You get the report the same day, with an in-person consultation to follow.
How to prepare
- Leave side gates unlocked
- Make a note of anything you’d like us to look at
- Dig out any old roof reports or invoices

If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or send us an email when you are ready.
