Thermal roof surveys for homes and businesses in Hertford Heath
A thermal survey is not a quick fix for every roof problem. It shows surface temperature, and things like sun, shade, reflections and wind all affect the readings. That’s why we check findings with moisture readings and a close visual inspection. The report is clear about what the images show and what they do not. If a finding cannot be confirmed, the report suggests a next step. If you’ve noticed thin or uneven insulation in the roof and water that travels before it shows, we can find out what’s behind it.
In a small place like Hertford Heath, 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.
Findings are set out part by part, from the coverings down to the gutters. You will see the good as well as the bad.

DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
What we are asked to look at in Hertford Heath
Once a leak has been fixed, people often ask whether the roof is still wet. Thermal images and moisture readings can suggest whether moisture is still trapped, given suitable conditions on the day.
Typical things we are asked to look at include:
- Damp that repairs haven’t cured
- Patches of heat loss across the roof
- Wet insulation beneath the membrane
- Wet areas near outlets and upstands
Anyone responsible for a site like Hertford Heath Primary and Nursery School will know that a view from above covers a wide roof far faster than walking it.
What to check before booking
- Are they insured for the work?
- What’s outside the scope of the survey
- How soon the report will arrive
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
Tips from our surveys
Over many surveys, some simple habits stand out:
- Check outlets after heavy rain
- Move stored items away from the loft hatch
- Keep the heating on as usual before a heat loss survey
- Note where damp appears and after what weather
Once we’ve been, the thermal images, photos and readings go into a single report. We explain what each image may mean, with our recommendations. Premium reports are sent the same day.
Keep outlets and gutters clear so water drains off the roof quickly. The less water sits, the less can find its way beneath.
How the survey works
On the day, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can be seen safely, using the ground, windows, the loft and a drone where applicable. Most surveys take about 1–2 hours for a house, with bigger or more complicated roofs taking longer. Somewhere as small as Hertford Heath, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We look at the roof from ground level, from windows and from the roof itself where it’s safe.
- Thermal images are taken to show differences in surface temperature.
- Any patterns of interest are checked with moisture readings where we can reach them.
- We write up the thermal images alongside ordinary photos and recommendations.
Getting ready for the survey
- Show us where any leaks or stains appear
- Have any paperwork from past roof work to hand
- Make a note of anything you’d like us to look at

Hertford Heath questions
Do you cover Hertford Heath?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
How do I find out if my home in Hertford Heath is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. 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.
What does a thermal roof survey show?
The images show how warm or cool each part of the surface is. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, which we then check with moisture readings.
Will the survey show heat loss through my roof?
It can show temperature patterns that point to missing or thin insulation. It shows most clearly when it is warm inside and cold outside. Where we can reach the loft safely, we check there too.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photos. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
How much does a thermal roof survey cost?
Our Premium Survey, from £400, includes thermal imaging. You also get an in-person consultation and a 12-month follow-up. Larger commercial roofs are quoted for their size.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
Landlord and commercial surveys in Hertford Heath
Letting agents can arrange access with tenants. Surveys run on weekdays and at weekends, which helps when tenants work during the week.
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
What a thermal roof survey looks like in Hertford Heath
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, 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. Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand.
The streets around a church such as Church of the Holy Trinity are often among the oldest in a place, and if your home is one of the older ones nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that’s where a view by drone or thermal camera helps.

Why it is worth a survey now in Hertford Heath
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 Hertford Heath, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A Basic Survey starts from £150, inc. VAT. Standard is from £250 and Premium from £400, both with VAT included. We confirm the exact price before you book.
