Thermal roof surveys for homes and businesses in Hudnall
Your report sets out the thermal images alongside ordinary photographs, making it clear where on the roof each pattern is. Each one comes with an explanation, the moisture readings and our recommendation. Premium reports are sent the same day. If you have questions, the in-person consultation gives you time to go through them. There’s a 12-month follow-up as well. We survey ceilings below the roof, pitched roof slopes and commercial roofs, and common reasons people get in touch are possible trapped moisture under a flat roof covering and thin or uneven insulation in the roof.
Villages like Hudnall often stand in open country, where wind can be strong. Strong wind or heavy rain stops a small drone flying, and calm conditions also suit thermal imaging best. We plan the journey, access and timing around the weather. If the day turns windy or wet, the visit can be moved.
We keep jargon out of it: where something needs attention, it says so plainly, and where it can wait, that is said too.

FAQs for Hudnall
Will you come out to Hudnall?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when you book.
Is Hudnall in the area you cover?
Yes. Our area covers London and South East England, and Hudnall is part of that. Just call 07833 053749 or email us and let us know about the property.
What insurance do you have?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Will the survey show heat loss through my roof?
Thermal images can suggest where heat is escaping and where insulation may be missing. We do not give energy ratings or heat loss calculations, but the images show where improvements may help.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
What can thermal imaging tell me about my roof?
The camera records how the surface temperature varies. The patterns can suggest wet insulation, gaps in insulation or heat escaping. We check what it shows with moisture readings.
Can you do a thermal survey in any weather?
The weather makes a real difference. It works best after a sunny day, with a dry roof surface and little wind. Rain, wind and heavy cloud can weaken the patterns, so we discuss the forecast when booking.
Tips from our surveys
A survey works best with a little help from you, before and after. Some tips:
- Take photos of stains as they appear, so we can compare
- Move stored items away from the loft hatch
- Remember the conditions on the day affect the results
- Keep the report to compare against after any repair
The report explains the conditions on the day and how they affected the images. It helps you judge how firm each finding is.
Consider a repeat survey after major work on the roof in suitable weather.
What this survey cannot tell you
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Reliable images in rain, strong wind or on a wet roof surface
- Hidden layers that need to be opened up to check
- Structural calculations, which need a structural engineer
If in doubt, ring 07833 053749 or drop us an email and we’ll suggest the right survey. What our survey covers.

What we’re asked to look at in Hudnall
Buyers sometimes want more than a visual look at the roof. The Premium Survey brings thermal imaging and a drone inspection where it applies, with a report the same day, which suits a purchase that is moving quickly.
Common reasons to book include:
- Damp that repairs haven’t cured
- Areas losing heat at the eaves and junctions
- Thin or uneven insulation in the roof
- Cold areas below the roof
Whatever the street in Hudnall, a roof costs least to look after when faults are caught early.
Choosing a roof surveyor
- Whether any drone flown is registered with the CAA
- Will they check the loft as well as the outside?
- What’s outside the scope of the survey
- How soon the report will arrive
Why get it checked now?
Once insulation under a membrane is wet, it tends to stay wet. Over time, it insulates less well and can harm the deck. Finding them early can mean a smaller job. In a small place like Hudnall, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
To find out what your survey will cost, phone 07833 053749 or send us an email with the address and a few details. We will confirm the figure before booking.

Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying. What can be done to an older roof may depend on listing or a conservation area. The council is the place to check, along with Historic England’s list, before anyone quotes for re-roofing.

Advice
Roof by roof
Single-ply and EPDM roofs
Single-ply PVC, TPO and EPDM roofs are often laid over insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
Loft insulation
From inside the loft, thermal imaging can show gaps in insulation and cold spots. We look where there’s safe access.
