Thermal imaging roof survey in Bernards Heath, Hertfordshire
Find out what’s going on with the roof before you decide what to do next. We carry out thermal roof surveys in Bernards Heath.
- Cold areas below the roof
- Possible trapped moisture under a flat roof covering
- Moisture around outlets and upstands
How a thermal roof survey works in Bernards Heath
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 our report notes the conditions and how they affected what we saw. If you are worried about damp patches with no obvious cause and leaks that are hard to trace, a survey will tell you what’s going on, whatever the roof.
Around Bernards Heath, older homes can have thin loft insulation and later additions with roofs of their own. A thermal image can show where heat is escaping or where moisture may be trapped, and drone photos show the roof surfaces themselves. Anything that looks like moisture is checked with a meter. Results depend on the weather, so the visit is planned around the forecast.
It is not only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

How we price thermal roof surveys
Prices vary from roof to roof, and it comes down to:
- Whether you choose the Basic, Standard or Premium Survey
- House, block, shop or office
- Chimneys, valleys, parapets and other details
- How tall the building is and how easy the roof is to see
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, which starts from £400, with VAT included. We’ll tell you which package suits the questions you have.
What to tell us when you contact us
Before you get in touch, it is useful to have:
- Any stains, drips or damp patches you’ve seen indoors
- Whether there is a loft hatch, a shared roof or tricky access
- Photos of the roof, taken safely from ground level or a window
- When you need the report by
You can call us seven days a week. To book or ask a question, phone 07833 053749 or drop us an email.
What happens on the day
We do not take risks to get a closer look. We inspect everything that’s safely in view, and if part of the roof can’t be seen, the report says so. Most visits take roughly 1–2 hours at a typical home, while a commercial roof takes nearer three to four hours. Parking around Bernards Heath is typically easier than in a town centre, but mention lanes, gates or long drives. Low roofs on bungalows can often be seen well from ground level, and the loft shows the rest, while taller roofs may need other vantage points or the drone where applicable.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- The roof is inspected visually from safe viewpoints.
- A thermal camera records how the surface temperature varies across the roof.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- The report sets out the images, what they suggest and what we recommend.
Before the survey
- If you are buying, let the agent know when we are coming
- Let us know about any leaks, stains or damp patches you know of
- Tell us where we can park nearby

What we look for on each type of roof
Loft insulation
In the loft space, the camera can pick up gaps and thin areas of insulation. We look where there is safe access.
Single-ply and EPDM roofs
On larger commercial single-ply roofs, thermal imaging can help target moisture readings. That makes the survey more focused.
Landlord and commercial surveys in Bernards Heath
Letting agents frequently book on a landlord’s behalf, with the report sent to whoever needs it. Access is agreed with the tenant ahead of time.
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Larger roofs take longer, so they’re priced to suit.
Thermal roof surveys around Bernards Heath
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. With Batchwood Hall about 1 mile west, Bernards Heath sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
The streets around a church such as Church of St Saviour are often among the oldest in a place, and if yours is one of the older homes nearby, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help. Hotels and guest houses near Bernards Heath cannot easily close rooms for a leak.

Why act early in Bernards Heath
Repeated repairs that don’t stop a leak are a sign the source hasn’t been traced. Combining the camera with moisture readings can help find it, rather than more guesswork. Around Bernards Heath, a leak in an older house can soak into timbers and plaster, and that is a much bigger job than the original defect.
Prices start from £400, including VAT. The final price depends on the size and height of the roof, access and which survey you book.

When to book a survey in Bernards Heath
Some defects simply cannot be seen with the eye. Trapped moisture, missing insulation and hidden heat loss are three examples. Thermal imaging gives us another way to look for them.
Common reasons to book include:
- Damp that repairs haven’t cured
- Damp around roof outlets and upstands
- Damp where roofs meet walls and chimneys
- Possible trapped moisture under a flat roof covering
Anyone responsible for a site like Garden Fields Junior Mixed and Infant School will know that a view from above covers a wide roof far faster than walking it.
Before booking anyone

- How long the report takes to arrive
- Whether any drone flown is registered with the CAA
- Whether the inside of the roof is included

Bernards Heath questions
Do you carry out roof surveys in Bernards Heath?
Yes. We survey roofs across London and the South East, and Bernards Heath is part of that. Just call 07833 053749 or drop us an email and let us know about the property.
Do you cover smaller places like Bernards Heath?
Yes, Bernards Heath is covered. We survey roofs across London and South East England, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
How long will you be at the property?
It typically takes about one to two hours at most homes, rising to roughly 3–4 hours on a commercial building. The written report follows by email, on the timescale of your package.
What’s the best way to book?
The quickest way is to phone 07833 053749 or send us an email. Give us the address and a few details about the roof. We survey on any day of the week.
How quickly is the report sent?
It depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
Can you use a thermal camera on a sloping roof?
It can help, but the results are frequently less clear than on a flat roof. The air space under slates and tiles can hide patterns, so we combine it with an inspection from the loft where there’s safe access.
