Airspace, weather and Barnes Cray roofs
Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help. Hall Place and Gardens, about 1.7 miles south-west, is one of the historic houses in the wider area around Barnes Cray. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
If yours is one of the older homes in the streets near Christ Church, thin or patchy insulation under an old roof often shows up clearly on a thermal image. If you look after a shop, office or commercial unit, for example near Broadway Shopping Centre, large commercial roofs are often easiest to see from the air or with a thermal camera.

Thermal roof survey in Barnes Cray: what you get
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera doesn’t see water itself, so we check what it shows with moisture readings. Thermal imaging is included in our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. If you’ve noticed leaks that are hard to trace and stains that keep coming back, a survey will tell you what’s going on.
Older cottages and houses around Barnes Cray may have little insulation, and some have extensions with their own roofs. Thermal patterns and close-up photos together give a fuller picture of the roof. Findings are checked with moisture readings where needed. Results depend on the weather, so the visit is planned around the forecast.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Barnes Cray: your questions answered
Will you come out to Barnes Cray?
Yes. Barnes Cray is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Do you cover Barnes Cray?
Yes. We survey roofs across London and South East England, and Barnes Cray is part of that. Just ring 07833 053749 or drop us an email and let us know about the property, and we will talk through which survey suits.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first, with the building owner or managing agent. Mention it when you contact us and we’ll plan the survey around it.
Can a thermal survey trace a roof leak?
It is a useful tool for tracing leaks, but not the only one. The results depend on conditions on the day. Where it cannot be pinned down, the report suggests a next step, such as electronic leak detection.
Will I get photos?
Yes. We photograph the roof as we go, and the report uses them to show each finding.
Which days do you carry out surveys?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days when booking.
What happens next?
You will get the report by email. With Standard there’s a follow-up consultation; with Premium, an in-person consultation.
Tips from our surveys
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Let us know where and when you’ve seen damp or stains
- Clear leaves from outlets and gutters each autumn
- Use the report as a baseline for later checks
- Remember the conditions on the day affect the results
Many people send the report to roofers, who can then quote for the areas shown. Each thermal image is matched to a normal photo, so the areas are easy to locate.
Have small defects in the covering fixed early. Once water gets under a membrane, it can travel far before it appears inside.

The survey, step by step
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. A typical survey takes about 1–2 hours at a typical home, and longer for a large or complex roof. A visit to Barnes Cray is planned like any other: the time, the access and where to park are agreed beforehand. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- We look at the roof from ground level, from windows and from the roof itself where it is safe.
- 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, photographs and our recommendations.
Before we arrive
- Move anything stored under the loft hatch
- If it isn’t your property yet, arrange access through the agent
- Have any paperwork from past roof work to hand
Getting a price

Signs you need a thermal roof survey in Barnes Cray
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 when the conditions on the day are suitable.
Problems we come across often include:
- Gaps in loft insulation
- Cold areas below the roof
- Damp where roofs meet walls and chimneys
- Moisture around outlets and upstands
For site and facilities teams at buildings like Haberdashers' Aske's Crayford Academy, a drone or thermal camera can show a large roof in a single visit.

- Will they check the loft as well as the outside?

Roof by roof
Pitched slate and tile roofs
On pitched roofs, slates and tiles over a ventilated space can mask what’s happening underneath. We back up what the camera shows with a look in the loft where we can.
Single-ply and EPDM roofs
On big single-ply roofs, the camera helps show where to take readings. That makes the survey more focused.
Checking the roof from the ground
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight.
For landlords and managing agents
We also survey roofs for businesses and commercial landlords. Bigger roofs take more time.
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client.
