Thermal roof surveys for homes and businesses in Weston
What a thermal camera can show depends a lot on the weather. A sunny day before the survey, a dry roof surface and little wind all help. Rain, a strong wind or heavy cloud can make the images less clear. We talk through the forecast as you book, and the report explains how the conditions on the day affected the results. Typical surveys look at missing or slipped insulation and possible trapped moisture under a flat roof covering, on flat roofs, ceilings below the roof and loft conversions.
Older buildings in small places like Weston may be listed or in a conservation area. A look from above or with a thermal imager does not touch the roof, so it is a gentle way to see the condition of an old roof. Check with the council before planning any work on a listed building or one in a conservation area.
You receive the findings 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.

How the survey changes by roof type
GRP fibreglass roofs
GRP roofs are laid over timber boards, so trapped moisture can affect the deck. Thermal imaging can suggest where that may be happening.
Pitched slate and tile roofs
Even on pitched roofs, the camera can point to heat loss and some damp. We explain what can and cannot be read from them.
Why get it checked now?
Once insulation under a membrane is wet, it tends to stay wet. Over time, it insulates less well and can harm the deck. Finding them early can mean a smaller job. In a small place like Weston, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Our price is from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, inc. VAT.

Weston: your questions answered
How do I find out if my home in Weston is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is Weston within the area you cover?
Yes, Weston is on our map. Villages and rural addresses get the same survey as a town house.
Can you give me structural calculations?
No. Our survey is not a structural engineer’s report, and it does not include calculations. We’ll recommend an engineer if we see signs that call for one.
Will the survey show heat loss through my roof?
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.
Can you survey a shared roof?
Yes, if the freeholder or managing agent agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
Will you walk on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where applicable let us see the rest.
What happens after the survey?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
What a thermal roof survey looks like in Weston
If your survey includes the drone, we check the Drone Safety Map for restrictions before flying. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Many roofs like these can’t be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place.
For site and facilities teams at buildings such as Weston Primary School, a view from above covers a wide roof far faster than walking it. If your home is one of the older ones in the streets near Church of the Holy Trinity, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that’s where a view from the air or with a thermal camera helps.
Weston is about 3 miles south-east of Letchworth, in Hertfordshire. Weston is part of the area we cover and the surrounding area across London and South East England. Weston is one of the places in Hertfordshire where we work for thermal roof surveys. You can also see our page for Milton Keynes.

What we can’t see
Without opening up the roof, some things stay hidden, so a survey has limits:
- Seeing water directly, as the camera shows temperature, not moisture
- Structural calculations, which need a structural engineer
- Hidden layers that need to be opened up to check
If you are not sure which survey you need, phone 07833 053749 or email us and we will give you a straight answer. The full list of what we check.

How the survey works
After the inspection, everything we found is written up as a report with photographs. As for time on site, it normally takes an hour or two for a house, with bigger or more complicated roofs taking longer. Rural addresses near Weston can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We check the roof from the ground, from windows and from the roof itself where it’s safe.
- A thermal camera records how the surface temperature varies across the roof.
- 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
- If the roof is shared, arrange access with whoever manages the building
- Keep pets out of the way during the survey
- If you’re buying, let the agent know when we’re coming

Checking the roof from the ground
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
For landlords and managing agents
Landlords, agents and building managers in Weston and across Hertfordshire can book any of our surveys. For a price for a let property or a block, ring 07833 053749 or use the contact form.
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Let us know about it when you book and we will plan the survey around it.
