Thermal imaging roof survey in Throcking, Hertfordshire
Wondering about the roof at a property in Throcking? You can book a thermal roof survey in Throcking and across Hertfordshire.
- Thin or uneven insulation in the roof
- Cold spots on ceilings under the roof
- Leaks far from where the stain appears
How a thermal roof survey works in Throcking
Your report sets out the thermal images alongside ordinary photos, making it clear where on the roof each pattern is. We explain what each pattern may mean, what the moisture readings found and what we recommend. With a Premium Survey, the report reaches you the same day. You can talk the findings through with us at the in-person consultation. There’s a 12-month follow-up as well. We survey flat roofs, commercial roofs and loft conversions, and the problems we’re asked to look at most are areas of a flat roof that may hold water and ceilings that feel colder in places.
Older buildings in small places like Throcking may be listed or in a conservation area. A look from the air or with a thermal camera does not touch the roof, so it’s 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.
What you get is a clear record of the roof on the day we saw it. That makes it useful now and a handy reference later, like when you want to compare after future work.

Drones, thermal imaging and Throcking roofs
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. If the drone is used for your survey, the flight is checked against the Drone Safety Map first.
If you look after a building such as Freman College, a view from above covers a wide roof far faster than walking it.
Throcking is about 6 miles north-east of Stevenage, in Hertfordshire. We carry out thermal roof surveys for householders, landlords and businesses in Throcking. Across Hertfordshire, we cover Throcking and the places around it. Our Chelmsford page covers surveys nearby.
We survey roofs across the SG9 postcode area for thermal roof surveys and the streets around it. We also cover Cottered (1 mile south-west), Chipping (1 mile north-east), Buntingford (2 miles east), Aspenden (2 miles south-east) and Layston (2 miles east). Within a short drive, we also cover Stevenage (6 miles south-west), Bishop's Stortford (11 miles south-east), Welwyn Garden City (12 miles south-west), Hitchin (9 miles west), Hoddesdon (14 miles south) and Hatfield (15 miles south-west).

What happens if roof problems are left?
Without thermal imaging, the only way to see how far water has spread is often to open up the roof. It helps when deciding whether to patch an area or replace the roof. Outbuildings and barns around Throcking are easy to forget, but a failed roof there can spoil what’s stored inside. It’s worth including them in a survey before a winter does the damage.
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. Thermal roof survey starts from £400, including VAT.

Do you need a thermal roof survey in Throcking?
Unexplained damp is one of the main reasons people ask for thermal imaging. A leak may start well away from where the stain appears. The camera helps narrow the search.
Look out for signs like these:
- Damp patches with no obvious cause
- Water that travels before it shows
- Wet insulation beneath the membrane
- Damp around roof outlets and upstands
The streets around a church like Holy Trinity Church are often among the oldest in a place, and if yours is one of the older homes nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view from above or with a thermal imager helps.
Before booking anyone
- How much experience they have with roofs like yours
- Their insurance cover
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What happens after the report arrives
Different roofs, different checks
GRP fibreglass roofs
Cracks in GRP can let water into the boards beneath. We look at cracks by eye and use the images to see whether there is a pattern around them.
Single-ply and EPDM roofs
Many single-ply and EPDM roofs sit on insulation boards. Wet boards can show as temperature differences on the images.
Tips from our surveys
Some practical points come up on survey after survey. They apply to most roofs:
- Use the report as a baseline for later checks
- Clear leaves from outlets and gutters each autumn
- Let us know where and when you’ve seen damp or stains
- Clear a path to the loft hatch before we arrive
Once we have 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.
Consider a repeat survey after major work on the roof in suitable weather.
Throcking: your questions answered
Do you cover Throcking?
We do. Every survey there gets the same written report with photos.
How do I find out if my home in Throcking is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
What conditions are best for thermal imaging?
Conditions on the day have a big effect on what the camera can show. A dry surface, little wind and a sunny spell beforehand help most. We record the conditions in the report, so you know how much weight to give the images.
Can thermal imaging show missing insulation?
The camera can point to heat loss and gaps in insulation. We don’t give energy ratings or heat loss calculations, but the images show where improvements may help.
Do you carry out surveys on Saturdays and Sundays?
Visits run seven days a week in the daytime. Just say which days work for you.
Is this an asbestos survey?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
What happens on the day
There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. The survey itself takes between one and two hours at a typical home, though large, tall or awkward roofs take more time. Older roofs in small places like Throcking can have low, tight loft spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- We go through the roof, the problem and the weather expected on the day.
- We look over the roof from wherever it’s safe.
- Thermal images are taken across the roof and, where there is 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.
Before the survey
- Have any questions written down, so nothing gets missed
- If you are buying, let the agent know when we are coming
- Keep pets in another room
How to book
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To get started, call 07833 053749 or drop us an email.
