How a thermal roof survey works in Key's Green
Thermal imaging is part of our Premium Survey, which starts from £400. It also includes a drone inspection where it applies, 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 phone 07833 053749 or send us an email with the address and what you’ve noticed. For big commercial roofs, we quote on size and access. Common reasons to book are damp patches with no obvious cause and possible trapped moisture under a flat roof covering, across insulated roof spaces, loft conversions and commercial roofs.
In a village or hamlet like Key's Green, roofs can be steep, old and hard to see from the lane. A drone and a thermal camera each give a view you can’t get from ground level. Weather and airspace are checked ahead of the visit, and the journey is planned in advance. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
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.

What we look for on each type of roof
Parapets, valleys and junctions
When valley or parapet gutters overflow, water can get into walls and ceilings. Thermal images, checked with moisture readings, can help trace it.
Felt and asphalt flat roofs
Water under felt or asphalt can stay hidden for years. Thermal imaging helps suggest where it is, given suitable conditions on the day.

When you need someone else
In fairness, there are limits to any roof survey:
- Structural calculations, which need a structural engineer
- A formal energy assessment
- Hidden layers that need to be opened up to check

FAQs for Key's Green
How do I find out if my home in Key's Green is listed?
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.
Is Key's Green within the area you cover?
Yes, we do. We survey roofs across London and South East England, from towns to the smallest villages. Longer journeys are simply planned in advance.
How long will you be at the property?
It typically takes roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. We will confirm the timing as you book.
Will you photograph what you find?
Yes. The report includes photos of what we found.
Can you check my loft insulation with a thermal camera?
It can show temperature patterns that point to missing or thin insulation. The difference is clearest when the building is heated and it is colder outside. Where we can reach the loft safely, we check there too.
Do you climb onto every roof?
Only where it is safe to do so. We look at everything that can be seen safely: from ground level, from windows, from inside the roof space, from the roof where it is safe and by drone where applicable. The report says if anything couldn’t be seen.
How experienced are you?
More than 5,000 surveys over 20+ years.
Tips from our surveys
Over many surveys, some simple habits stand out:
- Keep a record of when stains appear
- Clear a path to the loft hatch before we arrive
- Keep outlets and gutters clear to stop water sitting
- Ask us about the forecast if rain is expected
Once we have been, the thermal images, photos and readings go into a single report. We explain what each image may mean, alongside what we recommend. With a Premium Survey, you get the report the same day.
Deal with small splits and lifted seams promptly. Water that gets under a covering can spread a long way before it shows.
Thermal roof surveys in Key's Green: local notes
Across Kent, older roofs are often handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Older coverings on steep or tall roofs are hard to judge from below, so close-up aerial photos and thermal images help. If the drone is used for your survey, the flight is checked against the Drone Safety Map first.
The streets around a church such as Chapel Of Ease Of St Luke are frequently among the oldest in a place, and if yours is one of the older homes nearby, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement. Scotney Castle lies about 3.6 miles south-east, so building around Key's Green goes back a long way. Close-up aerial shots and thermal images let an old roof be checked without anyone disturbing it.
Key's Green is about 4 miles east of Royal Tunbridge Wells, in Kent. Anywhere in Key's Green, we can carry out thermal roof surveys at your property, on a weekday, Saturday or Sunday. Key's Green is one of the places in Kent where we work for thermal roof surveys. We also survey roofs in Maidstone.

DIY checks: what’s safe
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. Don’t go up yourself.
A DIY look is useful, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
How the survey works
Expect us to ask a few questions before we start, like when any problem began and what work has been done before. The inspection then takes an hour or two for most houses, though large, tall or awkward roofs take more time. In a small place like Key's Green, access is normally the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- The roof is inspected visually from safe viewpoints.
- We take thermal images of the roof to pick up temperature patterns.
- We check the patterns that stand out with moisture readings where there’s safe access.
- You get a report with thermal images, photos and our recommendations.
Before we arrive
- Note where any stains or damp appear
- Keep pets in another room
- Find any records of previous roof work
