Thermal roof survey in Northwood: what you get
What a thermal camera can show depends a lot on the weather. 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’ll discuss the weather with you when booking, and the report explains how the conditions on the day affected the results. We survey pitched roof slopes, loft conversions and ceilings below the roof, and people most often book us about damp around chimneys and parapets and damp patches with no obvious cause.
Older cottages and houses around Northwood may have little insulation, and some have extensions with their own roofs. Thermal patterns and close-up photos together give a fuller picture of the roof. Anything that looks like moisture is checked with a meter. Results depend on the weather, so the visit is planned around the forecast.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

Questions from Northwood
Does a conservation area affect roof work in Northwood?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is Northwood in the area you cover?
Yes, Northwood is within the area we cover. Our area covers London and South East England. You can ring 07833 053749 or send us an email with the address and some details, and we will talk through which survey suits.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you will need a RICS survey as well.
Will you go up on the roof?
Only when it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone, and the report notes anything we couldn’t see.
Can you use a thermal camera on a sloping roof?
On pitched roofs, the camera can point to heat loss and some damp patterns. Our report is clear about what can be read from them, and back them up with a visual inspection and moisture readings.
Does thermal imaging detect leaks directly?
Thermal imaging shows temperature rather than water. Because wet insulation holds heat for longer, it can show as a different temperature, and moisture readings are used to check it.
Can you check my loft insulation with a thermal camera?
Gaps and thin areas of insulation can show up on the camera. The difference is clearest when the building is heated and it is colder outside. We look from the loft as well, where there is safe access.

What happens on the day
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect between one and two hours on an ordinary house, and about three to four hours for a commercial roof. In a smaller place like Northwood, 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 by discussing the roof, any signs of damp and how the weather may affect the images.
- We check the roof from the ground, from windows and from the roof itself where it is 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.
- The report sets out the images, what they suggest and what we recommend.
Getting ready for the survey
- Unlock side gates and any roof access doors
- For flats, check roof access has been agreed
- Show us where any leaks or stains appear
Book a survey
If you’re buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply phone 07833 053749 or email us whenever suits you.

Pitched slate and tile roofs
Inside the loft space, thermal images can help with damp around stacks, valleys and roof windows. We check any patterns with moisture readings.
GRP fibreglass roofs
Glossy GRP can reflect heat. We take that into account and check findings with moisture readings.
Flying and imaging in Northwood
The coast is about 2 miles or less from Northwood, and coastal wind can be strong. Thermal imaging works best after a sunny day, with a dry roof surface and little wind, so the date is chosen with the forecast in mind. Quex Park, about 3.6 miles west, is one of the historic houses in the wider area around Northwood. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
Take an older house close to St Mark's Church: tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement. Shop and office owners around Westwood Cross may find that thermal images can show trapped moisture across a wide commercial roof. If you look after a building such as Dame Janet Primary Academy, big roofs are where aerial photos and thermal images show the most at once.
Northwood is about 1 mile north-west of Ramsgate, in Kent. Surveys in Northwood work the same way as everywhere we cover: a careful inspection, photographs and a written report. We cover towns and villages across Kent, large and small. We also survey roofs in Canterbury.

What affects the cost of thermal roof surveys
When we price a survey, we consider:
- Building height and the viewpoints available
- Extensions, dormers and garages with roofs of their own
- How big the roof is
- Whether you choose the Basic, Standard or Premium Survey
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Thermal roof survey starts from £400, including VAT.
Booking your survey
We will usually ask about:
- Photos of the roof, taken safely from ground level or a window
- Where the property is, with the postcode
- Any stains, drips or damp patches you’ve seen indoors
- What kind of property and roof it is
You can call us seven days a week. For a price or to book, phone 07833 053749 or use the contact form.
When you need someone else
Without opening up the roof, some things stay hidden, so a survey has limits:
- Proving moisture from the images alone
- Clear results when the conditions on the day are poor
- An energy rating for the building
If in doubt, phone 07833 053749 or use the contact form and we will suggest the right survey. What a survey covers and does not.
What we look at
- Insulated roof spaces
- Ceilings below the roof
- Pitched roof slopes
- Flat roofs
- Loft conversions
- Commercial roofs
Why get it checked now?
Repeated repairs that don’t stop a leak are a sign the source hasn’t been traced. Thermal imaging with moisture readings can help narrow it down, instead of trying repair after repair. Arranging work in a smaller place like Northwood is easier with notice than in an emergency. A survey gives you that notice.
Every price we give includes VAT. Thermal roof survey starts from £400, including VAT. You will know the exact price before you book.

Practical tips
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Some tips:
- Note where damp appears and after what weather
- Remember the conditions on the day affect the results
- Make sure the loft can be reached safely
- Photograph damp patches with the date
Where a pattern cannot be confirmed, the report says what could help, for instance electronic leak detection or a roofer opening up a small section.
Watch for new damp patches on ceilings beneath the roof. Catching a leak early stops insulation getting soaked.
