Chaulden Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof around Chaulden, with a written report you can act on. Book a weekday or weekend visit.
- Damp where roofs meet walls and chimneys
- Areas of a flat roof that may hold water
- Patches of heat loss across the roof
About our thermal roof survey in Chaulden
A thermal survey can point to places where heat is escaping through the roof. Missing or slipped insulation and gaps at the eaves often show up as temperature differences. The difference shows most clearly when it’s warm inside and cold outside. The report shows the images and explains what they may mean. It is not an energy rating or a heat loss calculation. We survey loft conversions, pitched roof slopes and ceilings below the roof, and people most often book us about leaks that are hard to trace and damp where roofs meet walls and chimneys.
In smaller places like Chaulden, many homes are bungalows and houses with roofs you can partly see from the ground. Chimney tops, valleys and rear slopes are where close-up or thermal images help most. Both depend on the weather on the day, as calm, dry conditions suit both. Even so, a close-up image often shows wear on ridges and flashings that a view from the ground misses.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

What happens on the day
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit usually takes an hour or two at a house, including the thermal images, and around 3–4 hours for a commercial roof. Some parts of a survey depend on the weather, so a visit to Chaulden is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
Before the survey
- Keep pets out of the way during the survey
- Find any records of previous roof work
- If you’re buying, let the agent know when we’re coming

Related advice
Before and after the survey
A few practical points come up again and again on our surveys. They apply to most roofs:
- Use the report as a baseline for later checks
- Ask us about the forecast if rain is expected
- Do not climb onto the roof to look for leaks yourself
- Move stored items away from the loft hatch
The report explains the conditions on the day and how they affected the images. That way you know how much weight to give each finding.
Keep outlets and gutters clear so water drains off the roof quickly. Less standing water means less chance of it getting under the covering.
Flying and imaging in Chaulden
If your survey includes the drone, we check the Drone Safety Map for restrictions before flying. Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand, before anyone quotes for re-roofing.
If you look after a building such as Chaulden Junior School, a drone or thermal camera can show a large roof in a single visit.

Your questions about thermal roof surveys in Chaulden
Is my home in Chaulden listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Do you cover smaller places like Chaulden?
We do. Villages and rural addresses get the same survey as a town house.
Will you fly a drone over my roof?
Yes, where it’s applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
Does this replace a RICS home survey?
No. This is a survey of the roof only, and it isn’t a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years, across London and South East England.
How does a thermal imaging roof survey work?
A thermal camera shows differences in surface temperature. The patterns can suggest wet insulation, gaps in insulation or heat escaping. We check what it shows with moisture readings.
Can thermal imaging show missing insulation?
Gaps and thin areas of insulation can show up on the camera. It shows most clearly when it is warm inside and cold outside. Where we can reach the loft safely, we check there too.
Roof by roof
Parapets, valleys and junctions
Problems where roof slopes and walls meet are often hidden. A careful visual inspection goes alongside the images.
Pitched slate and tile roofs
Inside the roof space, thermal images can help with damp around stacks, valleys and roof windows. Findings are checked with moisture readings.
Why get it checked now?
Before replacing a large flat roof, it’s useful to know how much of it is actually wet. Images backed by moisture readings show where problems seem to be before you commit. Around Chaulden, a leak in an older house can soak into timbers and plaster, and that is a much bigger job than the original defect.
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, inc. VAT. Size, height and access can affect the price too.

When to book a survey in Chaulden
After a long-running leak, insulation under a flat roof can stay wet. Knowing how much of the roof is affected helps decide between a local repair and more. Thermal images and moisture readings together can show the likely extent.
Problems we come across often include:
- Thin or uneven insulation in the roof
- Moisture around outlets and upstands
- Damp where roofs meet walls and chimneys
- Heat escaping through the roof
The streets around a church such as St Stephen are often among the oldest in a place, and if your house is among the older ones nearby, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Before booking any roof surveyor
- How soon the report will arrive
- Whether they hold professional indemnity and public liability insurance
- How long they’ve been surveying roofs
- What exactly goes into their report
DIY checks: what’s safe
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
