Frithsden Thermal Roof Survey
Thermal roof surveys around Frithsden, with findings in writing and pictures to back them up. Weekday and weekend visits available.
- Stains that keep coming back
- Thin or uneven insulation in the roof
- Wet insulation beneath the membrane
Why it is worth a survey now in Frithsden
Once insulation under a membrane is wet, it tends to stay wet. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. For older village homes like those around Frithsden, the right replacement materials aren’t always easy to find quickly. Spotting a problem early leaves room to find them.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.

How a thermal roof survey works in Frithsden
A thermal survey can point to places where heat is escaping through the roof. Gaps in loft insulation and poorly insulated areas can stand out on the images. It works best when the building is heated and it is colder outside. The report shows the images and explains what they may mean. We do not give energy ratings or heat loss calculations. We survey flat roofs, loft conversions and ceilings below the roof, and people most often book us about damp around chimneys and parapets and thin or uneven insulation in the roof.
Villages like Frithsden often stand in open country, where wind can be strong. A small drone can’t fly safely in strong wind or heavy rain, and thermal imaging works best with little wind. 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 example when you want to check whether anything has changed.

How it works
Once we’ve finished looking, we write up our findings as a written report with photos, emailed to you. As for time on site, it normally takes roughly 1–2 hours for most houses, with bigger or more complicated roofs taking longer. In a hamlet or village like Frithsden, a postcode doesn’t always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- First we discuss the roof, any damp and the forecast for the visit.
- We look over the roof from wherever it is safe.
- We take thermal images of the roof and of the loft where we can reach it.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
Getting ready for the survey
- Leave side gates unlocked
- If you are buying, let the agent know when we are coming
- Have any questions written down, so nothing gets missed

Honest limits
A survey is a careful look at the roof, but it cannot do everything. Its limits include:
- What’s inside walls or under coverings, without opening up
- Readings unaffected by sun, shade or reflections
- Proving moisture from the images alone
If you are not sure which survey you need, call 07833 053749 or send us an email and we’ll give you a straight answer. The full list of what we check.
What we check
- Commercial roofs
- Pitched roof slopes
- Ceilings below the roof
- Flat roofs
- Insulated roof spaces
- Loft conversions
DIY checks: what’s safe
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
What a survey costs
We confirm the exact price before you book. These are the things that affect it:
- Any need for thermal images or a drone flight
- Whether you choose the Basic, Standard or Premium Survey
- How big the roof is
- Extensions, dormers and garages with roofs of their own
All our prices include VAT. Prices start from £400, including VAT. You will know the price for the job before you book.
Getting in touch
The more you let us know, the easier it is to price the survey. When you contact us, let us know:
- Where water is showing inside, if it is
- The address and postcode of the property
- Pictures from the garden or a window, if you have them
- When you need the report by
We survey roofs on any day of the week. To arrange a day that suits you, ring 07833 053749 or use the contact form.
Common questions in Frithsden
Do you carry out roof surveys in Frithsden?
Yes, Frithsden is within the area we cover. Our area covers London and South East England. Just ring 07833 053749 or drop us an email and tell us about the property, and we’ll talk through which survey suits.
How do I find out if my home in Frithsden is listed?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
What will the report tell me?
You get our findings in writing, part by part, with photos, finishing with recommendations. The most urgent items are made clear.
How long does the survey take?
Time on site depends on the roof; most visits take an hour or two for most homes, plus time to check any thermal findings with moisture readings. The written report follows by email.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Can thermal imaging show missing insulation?
It can show temperature patterns that point to missing or thin insulation. It shows most clearly when it’s warm inside and cold outside. We look from the loft as well, where there is safe access.
Can you do a thermal survey in any weather?
The results depend on the weather. Dry, calm weather after some sun gives the best chance of clear images. Our report notes the conditions and how they affected the findings.
Airspace, weather and Frithsden roofs
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help. If the drone is used for your survey, the flight is checked against the Drone Safety Map first.
If you look after a building such as Potten End CofE Primary School, a drone or thermal camera can show a large roof in a single visit.

When to book a survey in Frithsden
Not every roof problem shows on the surface. Trapped moisture, missing insulation and hidden heat loss are three examples. Thermal imaging gives us another way to look for them.
Things that frequently lead to a survey include:
- Damp around chimneys and parapets
- Patches of heat loss across the roof
- Leaks far from where the stain appears
- Gaps in loft insulation
If you live in an older home near Church of St Lawrence, thin or patchy insulation under an old roof often shows up clearly on a thermal image.
What to check before booking
