Clayhall Thermal Roof Survey
We take a careful look at the roof at your property in Clayhall, with photographs and a written report.
- Cold spots on ceilings under the roof
- Damp where roofs meet walls and chimneys
- Wet areas near outlets and upstands
When to book a survey in Clayhall
People often book a thermal survey when a damp patch has no obvious cause. Water can travel under a roof covering or along timbers before it shows inside. The camera helps narrow the search.
Most people get in touch after spotting one of these:
- Thin or uneven insulation in the roof
- Damp that repairs haven’t cured
- Water that travels before it shows
- Ceilings that feel colder in places
For hotels and guest houses around Clayhall, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do.
Choosing a roof surveyor
- How long they’ve been surveying roofs
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether the price includes VAT
- Whether the inside of the roof is included
Thermal roof surveys for homes and businesses in Clayhall
On a flat roof, wet insulation holds heat longer than dry insulation. So a wet patch can show as a warmer or cooler area on the camera. This can give an idea of how far water has travelled beneath the membrane, something you cannot typically tell from the surface. We then check those areas with moisture readings. We survey ceilings below the roof, loft conversions and pitched roof slopes, and people most often book us about patches of heat loss across the roof and cold areas below the roof.
In smaller places like Clayhall, many homes are bungalows and houses with roofs you can partly see from the ground. The parts you can’t see, like rear slopes, valleys and chimney tops, are where a drone or thermal camera adds detail. The forecast decides the day. Even so, a close-up image often shows wear on ridges and flashings that a view from the ground misses.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Your questions about thermal roof surveys in Clayhall
Is my home in Clayhall listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Is Clayhall within the area you cover?
Yes, Clayhall is covered. We work right across London and South East England, and smaller places are part of that. Longer journeys are simply planned in advance.
How do I arrange a thermal roof survey in Clayhall?
Just call 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day.
What’s in the report?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
How many surveys have you done?
Over 20 years and more than 5,000 surveys, across London and South East England.
How fast do I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
Can thermal imaging show missing insulation?
It can show temperature patterns that point to missing or thin insulation. The difference is clearest when the building is heated and it is colder outside. Where we can reach the loft safely, we check there too.
How the survey works
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. Most surveys take about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. With a bit of garden around a house, as there often is around Clayhall, the roof can be viewed from several angles. Mention any side of the property we cannot get to. The loft, where there is safe access, completes the picture.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We look at the roof from ground level, from windows and from the roof itself where it’s safe.
- Thermal images are taken to show differences in surface temperature.
- We check the patterns that stand out with moisture readings where there is safe access.
- You get a report with thermal images, photos and our recommendations.
Before the survey
- Have any questions written down, so nothing gets missed
- Dig out any old roof reports or invoices
- If you are buying, check with the agent that we can get in
Arrange a survey
If you have photos of the roof, send them over. Pictures from ground level or a window are fine. To get started, phone 07833 053749 or email us.

Honest limits
A survey is a close look at the roof, but it can’t do everything. Its limits include:
- Readings unaffected by sun, shade or reflections
- A formal energy assessment
- Structural calculations, which need a structural engineer
If in doubt, ring 07833 053749 or email us and we’ll suggest the right survey. What a survey covers and does not.

What a survey costs
Several things affect the price of a survey:
- The shape of the roof and its details
- Height and safe access
- Roof area
- Any need for thermal images or a drone flight
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Our price is from £400, including VAT.
Helping us price your survey
You don’t need to know any roofing terms. Just tell us:
- Photos of the roof, taken safely from ground level or a window
- Access details, such as a loft hatch or a shared roof
- When you need the report by
- Where the property is, with the postcode
A quick phone call is normally the easiest start: call 07833 053749 or use the contact form. You will have a price before anything is arranged.
Different roofs, different checks
Parapets, valleys and junctions
Parapet and valley gutters can overflow inside a building. Thermal images, checked with moisture readings, can help trace it.
Single-ply and EPDM roofs
Single-ply PVC, TPO and EPDM roofs are often laid over insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
Thermal roof surveys in Clayhall: local notes
Clayhall lies within about 1 mile of the sea. Clear thermal results need a dry roof and little wind after a sunny day, so the date depends on the forecast. What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand.
If you live in an older home near St Francis, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image. Anyone responsible for a site like Haselworth Primary School will know that big roofs are where aerial photos and thermal images show the most at once.

Before and after the survey
Over many surveys, some simple habits stand out:
- Clear a path to the loft hatch before we arrive
- Note where damp appears and after what weather
- Keep outlets and gutters clear to stop water sitting
- Use the report as a baseline for later checks
We note the weather and surface conditions, and how they may have affected the results. It helps you judge how firm each finding is.
Watch for new damp patches on ceilings beneath the roof. Catching a leak early stops insulation getting soaked.
