How a thermal roof survey works in St Paul's Walden
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. It’s important to know that the camera shows temperature, not water, so we check what it shows with moisture readings. It comes as part of 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 leaks far from where the stain appears and damp that repairs haven’t cured, we can find out what’s behind it.
In a small place like St Paul's Walden, open ground can mean strong wind. Strong wind or heavy rain stops a small drone flying, and calm conditions also suit thermal imaging best. We plan the journey, access and timing around the weather. A change in the forecast can mean moving the visit to another day.
The report does not just list problems. It explains what we found, why it matters and what we recommend.

Can I check my roof myself?
A DIY look is useful, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Share it with us as you book.
How the survey works
Safety comes first on every visit. Everything that can be seen safely is inspected, and if part of the roof cannot be seen, the report says so. Most visits take about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Older roofs in small places like St Paul's Walden can have low, tight loft spaces, so tell us about the loft hatch and any ladder. We only go where it is safe.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there’s safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- The report pairs each thermal image with a photo and explains what it suggests.
Before the survey
- Keep pets inside or away from the areas we are looking at
- Have any questions written down, so nothing gets missed
- If it is not your property yet, arrange access through the agent

Advice
Before and after the survey
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Make sure the loft can be reached safely
- Heat the home normally on the days before
- Check from ground level or a window, never by climbing
- Remember the conditions on the day affect the results
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it’s easy to find each area on the roof.
Keep outlets and gutters clear so water drains off the roof quickly. Less standing water means less chance of it getting under the covering.

Flying and imaging in St Paul's Walden
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 is where a view from above or a thermal image earns its place. St Paul's Walden is about 1 mile from the edge of the flight restriction zone around Luton Airport. If your survey includes the drone, we check the exact boundary for the address before flying.
With Knebworth House about 2.4 miles south-east, the area around St Paul's Walden has a long history. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings. For an older house near a landmark such as All Saints Church, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.

Why act early in St Paul's Walden
A poorly insulated roof loses heat year after year. Thermal images can show where insulation is missing or has slipped, so improvements can go where they’re needed. For older village homes like those around St Paul's Walden, the right replacement materials are not always easy to find quickly. That is one more reason to find defects before they become urgent.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. We will give you the figure before anything is booked.

Common questions in St Paul's Walden
How do I find out if my home in St Paul's Walden is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.

Yes, smaller places are covered as well as towns. Our area covers London and the South East. Let us know about access, parking and anything unusual about getting there when booking.
Will you photograph what you find?
Yes. We photograph the roof as we go, and they go into the written report.
How much does a thermal roof survey cost?

Will you go up on the roof?
Only when it is safe. 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, and the report records anything we couldn’t see.
How long have you been surveying roofs?

When to book a survey in St Paul's Walden
Flat roofs that have leaked for a while can have wet insulation under the covering. Owners want to know how far it has spread before deciding what to do. A thermal survey, checked with moisture readings, can give a much clearer picture.
Things that often lead to a survey include:
- Wet insulation beneath the membrane
- Cold areas below the roof
- Leaks that are hard to trace
- Damp patches with no obvious cause
If you look after a building like St Paul's Walden Primary School, big roofs are where close-up aerial shots and thermal images show the most at once.
Questions to ask before you book
- What’s outside the scope of the survey
- Is VAT included in the price?
- Whether you get a written report with photos
- How they’ll see the roof: from the ground, the loft, the roof or by drone
