Newgate Street Thermal Roof Survey
Find out the condition of the roof at your property in Newgate Street from an independent roof surveyor. We visit on weekdays and at weekends.
- Damp patches with no obvious cause
- Cold areas below the roof
- Possible trapped moisture under a flat roof covering
Before and after the survey
You do not need to be a roofer to help. Here’s what helps most:
- Use the report as a baseline for later checks
- Ask us about the forecast if rain is expected
- Move stored items away from the loft hatch
- Check outlets after heavy rain
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.
Have small defects in the covering fixed early. Once water gets under a membrane, it can travel far before it appears inside.
How a thermal roof survey works in Newgate Street
Thermal imaging can also show where a roof is losing heat. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it is warm inside and cold outside. The report shows the images and explains what they may mean. It is not an energy rating or a heat loss calculation. We’re often asked to look into leaks that are hard to trace and gaps in loft insulation, across pitched roof slopes, ceilings below the roof and insulated roof spaces.
Somewhere as small as Newgate Street, older roofs are frequently steep and partly hidden by trees or outbuildings. A drone and a thermal camera each give a view you cannot get from ground level. Both the forecast and the airspace are checked first, and the journey is planned beforehand. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

What a thermal roof survey does not cover
We only report what can safely be seen on the day, so some things are outside what a survey can do:
- Whether the deck or roof structure is strong enough
- What’s inside walls or under coverings, without opening up
- Clear results when the conditions on the day are poor
If you’re not sure which survey you need, ring 07833 053749 or email us and we will give you a straight answer. What our survey covers.
Roof types and parts we check
- Ceilings below the roof
- Flat roofs
- Insulated roof spaces

- Pitched roof slopes
How we price thermal roof surveys
A few things affect what a survey costs:
- Roof area
- How many separate roofs there are, such as extensions, dormers and garages
- Whether it’s a home or a commercial building
- How complicated the roof is, with its valleys, chimneys and parapets
Every price we give includes VAT. Prices start from £400, including VAT. You will know the price for the job before you book.

The survey, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes about one to two hours on an ordinary house, with bigger or more complicated roofs taking longer. If you have questions on the day, just ask. Cottages and farmhouses around Newgate Street often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we can’t see is noted.
- You tell us 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.
- You get the report the same day, with an in-person consultation to follow.
Before we arrive
- Move anything stored under the loft hatch
- Jot down any questions you want answered
- If you’re buying, let the agent know when we’re coming

Your questions about thermal roof surveys in Newgate Street
Is Newgate Street in the area you cover?
Yes. We survey roofs across London and South East England, and Newgate Street is part of that. Just call 07833 053749 or use the contact form and let us know about the property, and we’ll talk through which survey suits.
Is my home in Newgate Street listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is it a structural engineer’s report?
No. We point out what can be seen, such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
Does someone need to be in?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you when booking.
Can a thermal survey trace a roof leak?
Thermal imaging can help, alongside other checks. The results depend on conditions on the day. If the source can’t be confirmed, we’ll say what could help next, such as electronic leak detection.
Does thermal imaging detect leaks directly?
Not directly. It shows surface temperature, and wet areas can show up because they hold heat differently. That is why we check any patterns with moisture readings.
How long will you be at the property?
Most surveys take between one and two hours at a typical home, and longer for a large or complex roof. The report follows by email.
What happens if roof problems are left?
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. Older and listed buildings around Newgate Street may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
Prices start from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included.

Drones, thermal imaging and Newgate Street roofs
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help. Wyllyotts Manor, about 4 miles south-west, is one of the historic houses in the wider area around Newgate Street. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
Take an older house close to Church of St Mary Ponsbourne: steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view by drone or thermal camera helps. Anyone responsible for a site like Ponsbourne St Mary's Church of England Primary School will know that big roofs are where photos from the air and thermal images show the most at once.
