Gustard Wood Thermal Roof Survey

How the survey changes by roof type
Felt and asphalt flat roofs
Felt and asphalt roofs often show wet areas as patches that differ from the rest. Moisture readings are used to check them.
Single-ply and EPDM roofs
Many single-ply and EPDM roofs sit on insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
Thermal roof survey in Gustard Wood: what you get
Thermal imaging can also show where a roof is losing heat. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it is warm inside and cold outside. The report shows the images and explains what they may mean. We don’t give energy ratings or heat loss calculations. If you’ve noticed water getting in at parapets and stacks and possible trapped moisture under a flat roof covering, a survey will tell you what’s going on, whatever the roof.
In a village or hamlet like Gustard Wood, roofs can be steep, old and hard to see from the lane. A drone and a thermal camera each give a view you can’t get from the ground. Both the forecast and the airspace are checked first, and the journey is planned in advance. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
The report does not just list problems. It explains what we found, why it matters and what we recommend.

Gustard Wood questions
Does a conservation area affect roof work in Gustard Wood?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you cover smaller places like Gustard Wood?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Can a thermal camera see water?
The camera doesn’t see water itself. Wet insulation holds heat longer than dry, so it can stand out, and moisture readings are used to check it.
Will you walk on the roof?
Only if it is safe. We inspect what can be seen safely: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where applicable. The report says if anything couldn’t be seen.
How fast do I get the report?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
Do you test for asbestos?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them.
Will thermal imaging find my leak?
It can help narrow down where water may be getting in. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. It is used alongside a close inspection and moisture readings, as the camera alone cannot prove a leak.
What happens if roof problems are left?
For buyers, a thermal survey adds detail that a visual inspection cannot give. Hidden problems found before exchange can be raised with the seller or agent. Outbuildings and barns around Gustard Wood are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
A Basic Survey starts from £150, with VAT included. The Standard Survey starts from £250 and the Premium Survey from £400. We confirm the price for your survey before booking.

When to book a survey in Gustard Wood
People often book a thermal survey when a damp patch has no obvious cause. A leak may start well away from where the stain appears. Temperature patterns can help narrow down where to look.
Look out for signs like these:
- Damp around chimneys and parapets
- Cold spots on ceilings under the roof
- Thin or uneven insulation in the roof
- Areas of a flat roof that may hold water
The streets around a church like St Peter are often among the oldest in a place, and if your house is among the older ones nearby, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.
Before you book any roof surveyor
- What’s outside the scope of the survey
- Whether the loft space is looked at, where there is one
- Whether you get a written report with photos
- Their report turnaround times
Tips that help
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Tips:
- Leave the roof to people with safe access
- Keep outlets and gutters clear to stop water sitting
- File the images with your roof records
- Remember the conditions on the day affect the results
If the images suggest moisture that can’t be confirmed, we will say what would help next, such as electronic leak detection or opening up a small area.
Keep an eye on ceilings under the roof for new stains. Early action keeps insulation from staying wet.

How we price thermal roof surveys
What a survey costs depends on the time and equipment it needs. That comes down to:
- Roof area
- How tall the building is and how easy the roof is to see
- Commercial roofs and larger buildings
- Basic, Standard or Premium
Every price we give includes VAT. Prices start from £400, including VAT. We confirm the exact price before booking.
Helping us price your survey
You do not need to know any roofing terms. It is enough to let us know:
- Where the property is, with the postcode
- How the loft is reached, if there is one
- The kind of building and roof involved
- Any deadline, such as an exchange date
We survey roofs on any day of the week. To arrange a day that suits you, ring 07833 053749 or use the contact form with the address and the days you’d prefer.
What happens on the day
The visit usually starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect about 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Somewhere as small as Gustard Wood, 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.
- The roof is inspected visually from safe viewpoints.
- We take thermal images of the roof to pick up temperature patterns.
- We check the patterns that stand out with moisture readings where there’s safe access.
- We write up the thermal images alongside ordinary photos and recommendations.
Before the survey
- Have any paperwork from past roof work to hand
- Leave a clear route to the loft
- Make sure pets are kept safely away
