Thermal imaging roof survey in Norcott Hill, Hertfordshire
We take a careful look at the roof at your property in Norcott Hill, with photographs and a written report.
- Heat escaping through the roof
- Gaps in loft insulation
- Wet insulation beneath the membrane
What affects the cost of thermal roof surveys
The price reflects the time and kit the roof needs. The main factors are:
- House, block, shop or office
- The height of the building and how the roof can be seen safely
- Whether you choose the Basic, Standard or Premium Survey
- How many separate roofs there are, such as extensions, dormers and garages
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Prices start from £400, including VAT.
Helping us price your survey
Before you get in touch, it helps to have:
- When you need the report by

Thermal roof survey in Norcott Hill: what you get
On a flat roof, wet insulation holds heat longer than dry insulation. So a wet patch can show as a warmer or cooler area on the camera. This can give an idea of how far water has travelled beneath the membrane, something you can’t normally tell from the surface. Moisture readings are then used to check what the camera suggests. We survey loft conversions, flat roofs and insulated roof spaces, and common reasons people get in touch are damp around roof outlets and upstands and heat escaping through the roof.
Some older homes in villages like Norcott Hill are listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, which suits a building where any change needs care, before anyone decides what work it needs. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

What we do, step by step
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 about one to two hours at a typical home, and more on a big or complicated roof. Around Norcott Hill, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. We only go where it’s safe.
- First we discuss the roof, any damp and the forecast for the visit.
- We look over the roof from wherever it is safe.
- 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.
- Each image is set beside a normal photo and explained in the report.
Preparing for the visit
- Unlock side gates and any roof access doors
- Point out any leaks or damp patches
- Have any paperwork from past roof work to hand
Arrange a survey
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, phone 07833 053749 or send us an email.

Airspace, weather and Norcott Hill roofs
With Cholesbury Manor House about 3.1 miles south-west, Norcott Hill sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. 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. Older coverings on steep or tall roofs are hard to judge from below, so close-up photos from the air and thermal images help.
Anyone responsible for a site like St Mary's CofE Primary School will know that thermal images can show where wet insulation sits under a big flat roof.

FAQs for Norcott Hill
Do you cover Norcott Hill?
Yes. We work right across London and South East England, and Norcott Hill is part of that. Just call 07833 053749 or use the contact form and let us know about the property.
Will you come out to Norcott Hill?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Just mention lanes, gates or anything else about the route as you book.
Can you use a thermal camera on a sloping roof?
It can show heat loss and some damp, but it has more limits there. We explain what the images can and cannot tell you, and back them up with a visual inspection and moisture readings.
Will the camera show exactly where the water is?
The camera does not see water itself. Because wet insulation holds heat for longer, it can show as a different temperature, and moisture readings are used to check it.
Can a thermal survey trace a roof leak?
Thermal imaging can help, alongside other checks. What it shows depends on the weather and the roof. If the source cannot be confirmed, we’ll say what could help next, such as electronic leak detection.
Will I get photos?
Yes, every report has them. Each finding is shown in a picture where possible.
How long is the visit?
Expect it to take between one and two hours for most homes, plus time to check any thermal findings with moisture readings. You will then get the report by email, on the timescale of your package.
When you need someone else
To be straight with you, a roof survey has limits:
- Insulation values or heat loss calculations
- Confirming water without moisture readings
- Readings unaffected by sun, shade or reflections
If in doubt, ring 07833 053749 or drop us an email and we will suggest the right survey. What our survey covers.
What we look at
- Commercial roofs
- Pitched roof slopes
- Insulated roof spaces
- Flat roofs
- Loft conversions
- Ceilings below the roof
Leave it or get it looked at?
Thermal images can suggest the extent of wet areas without cutting into the roof. It helps when deciding whether to patch an area or replace the roof. Around Norcott Hill, older homes often have old roof timbers, where water from a failed roof can cause rot if it is left.
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.

Common roof problems in Norcott Hill
After a repair, some owners want to know whether the roof has dried out. A thermal survey with moisture readings can show whether wet areas remain, given suitable conditions on the day.
Typical things we are asked to look at include:
- Cold spots on ceilings under the roof
- Leaks far from where the stain appears
- Damp where roofs meet walls and chimneys
- Areas losing heat at the eaves and junctions
If your home is one of the older ones in the streets near Church of Saint Mary, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view from the air or with a thermal camera helps.
Choosing a roof surveyor
- What follow-up you get after the report
- What exactly goes into their report
- Which limits apply to the survey
- How much experience they have with roofs like yours
For landlords and managing agents
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we’ll plan the visit with that in mind.
