Thermal roof surveys for homes and businesses in Knaphill
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. It’s important to know that the camera shows temperature, not water, so findings are checked with moisture readings. Thermal imaging is included in our Premium Survey, from £400. The report also notes the conditions on the day, since they affect what the camera can show. If you’ve noticed areas of a flat roof that may hold water and cold spots on ceilings under the roof, we can find out what’s behind it, on pitched roof slopes, commercial roofs and loft conversions alike.
Even in a smaller place like Knaphill, there may be airfields or restrictions nearby, so every drone flight starts with a check of the Drone Safety Map. Open ground can mean stronger wind, which also affects whether a small drone can fly. Each flight is planned with neighbours’ privacy in mind, as well as the airspace and the wind.
The written findings come by email, ready to forward to whoever needs them. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

What a thermal roof survey does not cover
To be straight with you, a roof survey has limits:
- Structural calculations, which need a structural engineer
- Readings unaffected by sun, shade or reflections
- Hidden layers that need to be opened up to check
Not sure which survey suits your roof? You can call 07833 053749 or drop us an email and we’ll tell you before booking. What our survey covers.
Roofs we survey in Knaphill
- Pitched roof slopes
- Flat roofs
- Insulated roof spaces
- Loft conversions
- Ceilings below the roof
- Commercial roofs
What we are asked to look at in Knaphill
Some buyers want extra detail before they commit to a purchase. The Premium Survey brings thermal imaging and a drone inspection where applicable, with a report the same day, which helps when timescales are tight.
A survey makes sense if you’ve noticed:
- Wet insulation beneath the membrane
- Damp that repairs haven’t cured
- Heat escaping through the roof
- Damp around chimneys and parapets
Anyone responsible for a site like Knaphill School will know that thermal images can show where wet insulation sits under a big flat roof.
Choosing a roof surveyor
- When you’ll get the report
- Their insurance cover
- Is there a chance to talk the report through?
- Do they have a CAA Flyer ID and Operator ID for drone work?
What we do, step by step
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from each safe vantage point, take photographs as we go and record our findings for the written report. Most visits take about 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. In a smaller place like Knaphill, as anywhere, the forecast plays a part: drone flights and thermal imaging need the right conditions, while a look from the ground and the loft can go ahead in most weather.
- We start with the roof, its history and any signs of damp or heat loss.
- 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
- Keep pets inside or away from the areas we are looking at
- Unlock side gates and any roof access doors
- Buyers: confirm access with the estate agent or seller
Arrange a survey
If you are buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply ring 07833 053749 or send us an email whenever suits you.
Advice
Flying and imaging in Knaphill
Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. Re-roofing in different materials may need permission there. If your survey includes the drone, we check the Drone Safety Map for restrictions before flying.
If you run a business near The Peacocks, a commercial roof can be photographed from above without anyone walking on it. The streets around a church like St Hugh of Lincoln's Church are frequently among the oldest in a place, and if yours is one of the older homes nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view from the air or with a thermal camera helps.

Your questions about thermal roof surveys in Knaphill
How do I find out if my home in Knaphill is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Do you carry out roof surveys in Knaphill?
Yes, Knaphill is within the area we cover. Our area covers London and the South East. You can ring 07833 053749 or use the contact form with the address and some details.
Will thermal imaging find my leak?
It is a useful tool for tracing leaks, but not the only one. What it shows depends on the weather and the roof. If the source cannot be confirmed, we’ll say what could help next, such as electronic leak detection.
Which days do you carry out surveys?
Surveys run on any day of the week. To find a day that suits you, call 07833 053749 or drop us an email.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
How quickly is the report sent?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed, ready to forward.
Which survey includes thermal imaging?
It comes with our Premium Survey, which starts from £400. The Premium Survey also covers a full inspection, drone inspection where applicable, structural analysis and a report on the same day.
Why it is worth a survey now in Knaphill
For buyers, a thermal survey adds detail that a visual inspection cannot give. Finding hidden moisture before exchange gives you facts to raise with the seller. Arranging work in a smaller place like Knaphill is easier with notice than in an emergency. Knowing early gives you time to get the right people in.
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. Size, height and access can affect the price too.

Take a look at what a roof survey costs and what we found on two real jobs.
Different roofs, different checks
Parapets, valleys and junctions
Junctions where roofs meet walls, parapets and valleys are common places for water to get in. Thermal imaging can help show damp patterns around them.
Loft insulation
In the roof space, the camera can pick up gaps and thin areas of insulation. We look where there’s safe access.
Surveys for landlords and agents in Knaphill
If you own several properties, you can book surveys for several addresses. To discuss a number of properties, ring 07833 053749 or send us an email.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
