Thermal imaging roof survey in Loudwater, Hertfordshire
We take a careful look at the roof at your property in Loudwater, and put it all in a report with photographs.
- Damp patches with no obvious cause
- Water getting in at parapets and stacks
- Thin or uneven insulation in the roof
Thermal roof survey in Loudwater
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’s warm inside and cold outside. Our report points out what the images suggest and where to look more closely. We don’t give energy ratings or heat loss calculations. Typical surveys look at areas of a flat roof that may hold water and damp around chimneys and parapets, across loft conversions, insulated roof spaces and flat roofs.
Older buildings in small places like Loudwater may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, which suits a building where any change needs care. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

What else we do in Loudwater
Thermal roof surveys in Loudwater: local notes
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Many roofs like these cannot be judged properly from the pavement, and that is where a view from above or a thermal image earns its place. Historic houses like Chenies Manor House, about 2.5 miles north-west, show how far back building in the area around Loudwater goes. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
If your home is one of the older ones in the streets near Christ Church, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view from above or with a thermal imager helps. If you look after a building like Christ Church Chorleywood CofE School, a drone or thermal camera can show a large roof in a single visit.
Loudwater is about 1 mile north-east of Chorleywood, in Hertfordshire. Bookings from Loudwater are handled just like any other: a call or an email, a price, then a date.

- Hidden layers that need to be opened up to check
- An energy rating for the building
- A structural engineer’s assessment

Loudwater: your questions answered
Is Loudwater in the area you cover?
Yes, Loudwater is within the area we cover. We cover the whole of London and South East England. Just call 07833 053749 or use the contact form and let us know about the property, and we will talk through which survey suits.
Will you come out to Loudwater?
Yes, we do. Our area covers London and the South East, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
Which days do you carry out surveys?
We survey seven days a week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
Do you test for asbestos?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.
How many surveys have you done?
We have completed more than 5,000 surveys, over more than 20 years, and 98% of clients are satisfied.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access, while outside access can be discussed when booking.
What happens next?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
How the survey changes by roof type
Felt and asphalt flat roofs
On felt and asphalt flat roofs, wet insulation can show as a temperature difference across the surface. Moisture readings are used to check them.
Single-ply and EPDM roofs
On big single-ply roofs, the camera helps show where to take readings. It focuses the survey on the areas that matter.
Do you need a thermal roof survey in Loudwater?
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Missing or slipped insulation can stand out as temperature differences, particularly when there’s a clear difference between inside and outside.
A survey makes sense if you’ve noticed:
- Wet insulation beneath the membrane
- Patches of heat loss across the roof
- Cold areas below the roof
- Wet areas near outlets and upstands
If you run a business near Charter Place, big, flat commercial roofs are where aerial photos and thermal images help most.
Questions to ask before booking
- What they will not be able to tell you
- What happens after the report arrives
- What the report includes, and whether it has photographs
- Which parts of the roof they’ll actually see
What we do, step by step
Every roof is different, but as a rough guide the survey takes between one and two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. You’re welcome to ask questions while we’re there. In a hamlet or village like Loudwater, a postcode doesn’t always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- 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.
Before we arrive
- Find any records of previous roof work
- Leave a clear route to the loft
- For a flat or shared roof, check access with whoever owns or manages the building

Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, phone 07833 053749 or drop us an email with the address and the days you’d prefer.
