Thermal roof survey in Ashridge: what you get
Thermal imaging works best in the right conditions. It’s useful to have a sunny day beforehand, a dry surface and calm air. Rain, a strong wind or heavy cloud can make the images less clear. We will discuss the weather with you when booking, and our report notes the conditions and how they affected what we saw. Typical surveys look at leaks far from where the stain appears and cold spots on ceilings under the roof, on ceilings below the roof, loft conversions and commercial roofs.
In a small place like Ashridge, open ground can mean strong wind. High wind or heavy rain stops a small drone flying, and calm conditions also suit thermal imaging best. The visit is planned around the forecast, along with the journey and access. If the day turns windy or wet, the visit can be moved.
The report records the roof as we found it on the day. That makes it useful now and a handy reference later, for instance when you want to check whether anything has changed.

How we price thermal roof surveys
To price your survey, we look at:
- How tall the building is and how easy the roof is to see
- Commercial roofs and larger buildings
- Whether you choose the Basic, Standard or Premium Survey
- Extra roofs, like extensions, dormers or garages
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
What we need to know
What helps most when you contact us:
- Access details, such as a loft hatch or a shared roof
- The style of property, from a terrace to a block
- Photos of the roof, taken safely from ground level or a window
- Where water is showing inside, if it is
To arrange a survey, call 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You will know the price before anything is booked.
Do you need a thermal roof survey in Ashridge?
Not every roof problem shows on the surface. Wet insulation, gaps in insulation and heat loss are frequently invisible from outside. A thermal camera adds another way of finding them.
Look out for signs like these:
- Wet areas near outlets and upstands
- Gaps in loft insulation
- Ceilings that feel colder in places
- Leaks that are hard to trace
For properties in and around Ashridge, we look at whatever is safely visible and explain what we find.

Practical tips
Small things make a difference. Some pointers:
- Let us know where and when you’ve seen damp or stains
- Photograph damp patches with the date
- Check outlets after heavy rain
- Leave the roof to people with safe access
Many people send the report to roofers, who can then quote for the areas shown. Each thermal image is matched to a normal photo, so the areas are easy to locate.
Clear outlets and gutters regularly, so water does not sit on the roof. The less water sits, the less can find its way beneath.

The survey, step by step
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, take photographs as we go and make notes for the report. It typically takes between one and two hours at most homes, rising to roughly 3–4 hours on a commercial building. Somewhere like Ashridge needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect what can safely be seen, inside and out.
- You let us know about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- 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.
How to prepare
- Unlock side gates and any roof access doors
- Let us know about parking near the property
- Make a note of anything you’d like us to look at

Advice
Thermal roof surveys in Ashridge: local notes
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, ideally before any re-roofing is planned. If your survey includes the drone, we check the Drone Safety Map for restrictions before flying.
For any home in Ashridge, it is the small, early fault that is cheapest to put right.

Ashridge: your questions answered
Is Ashridge within the area you cover?
Yes, Ashridge is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Do you carry out roof surveys in Ashridge?
Yes, Ashridge is within the area we cover. Our area covers London and South East England. You can ring 07833 053749 or use the contact form with the address and a few details.
What can thermal imaging tell me about my roof?
A thermal camera shows differences in surface temperature. Those patterns can point to trapped moisture, missing insulation or heat loss. We check what it shows with moisture readings.
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.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
What happens after the survey?
You receive the written report by email, with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are often shared, so we need permission from whoever owns or manages the building. We can only inspect what we’re given access to.
When you need someone else
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Readings unaffected by sun, shade or reflections
- Seeing water directly, as the camera shows temperature, not moisture
- The condition of timbers we cannot see
If in doubt, phone 07833 053749 or drop us an email and we’ll recommend the right survey. The full list of what we check.
What we check
- Pitched roof slopes
- Commercial roofs
- Flat roofs
- Loft conversions
- Ceilings below the roof
- Insulated roof spaces
Different roofs, different checks
GRP fibreglass roofs
Water under a GRP roof can reach the timber deck. Thermal imaging can suggest where that may be happening.
Single-ply and EPDM roofs
Thin membranes can show patterns from the layers beneath. Reflections from shiny surfaces can affect readings, which we allow for.
