Thermal imaging roof survey in Ley Green, Hertfordshire
Thermal roof surveys around Ley Green, with findings in writing and pictures to back them up. Weekday and weekend visits available.

- Areas of a flat roof that may hold water

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. In a place like Ley Green, a barn or garage roof left to fail puts whatever is inside at risk. It’s worth including them in a survey before a winter does the damage.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. We’ll give you the figure before anything is booked.

Thermal roof survey in Ley Green: what you get
Our Premium Survey, from £400, brings together a full roof inspection and thermal imaging. It also includes a drone inspection where applicable, a structural analysis and a same-day report. There is an in-person consultation as well, plus a follow-up 12 months later. To book, just call 07833 053749 or drop us an email with the address and what you’ve noticed. For big commercial roofs, we quote on size and access. We survey ceilings below the roof, loft conversions and insulated roof spaces, and the problems we’re asked to look at most are leaks that are hard to trace and wet insulation beneath the membrane.
Older buildings in small places like Ley Green may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on 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.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Thermal roof surveys in Ley Green: local notes
Ley Green is about 1 mile from the edge of the flight restriction zone around Luton Airport. If your survey includes the drone, the exact boundary is checked for the address first. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common 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.
If your home is one of the older ones in the streets near Church of St Mary, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view by drone or thermal camera helps. Historic houses like Knebworth House, about 4.9 miles south-east, show how far back building around Ley Green goes. A drone or thermal survey does not involve any work on the roof, which suits older buildings. Take a building like Preston Primary School: thermal images can show where wet insulation sits under a big flat roof.

DIY checks: what’s safe
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Common questions in Ley Green
Is my home in Ley Green listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Will you come out to Ley Green?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Just mention lanes, gates or anything else about the route when you book.
Does the weather affect a thermal survey?
The results depend on the weather. Dry, calm weather after some sun gives the best chance of clear images. We record the conditions in the report, so you know how much weight to give the images.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
Can a thermal survey trace a roof leak?
It often helps show where to look. Patterns can suggest where trapped water has spread. It’s used alongside a close inspection and moisture readings, as the camera alone can’t prove a leak.
Do you test for asbestos?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.

Tips from our surveys
Most of what helps is simple and safe from ground level. Our suggestions:
- Clear leaves from outlets and gutters each autumn
- Move stored items away from the loft hatch
- Heat the home normally on the days before
- Remember the conditions on the day affect the results
Buyers can use the findings when talking to the seller or agent. It is your decision how to use it, whether you ask for work before completion or discuss the price.
Watch for new damp patches on ceilings beneath the roof. Catching a leak early stops insulation getting soaked.
The survey, step by step
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. For a village or hamlet like Ley Green, the journey is planned ahead of time: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- 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
- Make sure the loft hatch can be reached
- Show us where any leaks or stains appear
- Buyers: confirm access with the estate agent or seller
