Thermal imaging roof survey in Charlton, West Sussex
Thermal imaging to find moisture and heat loss patterns in a roof across Charlton, using drones and thermal imaging where it applies. Call or email for a price.
- Thin or uneven insulation in the roof
- Possible trapped moisture under a flat roof covering
- Damp patches with no obvious cause
When to book a survey in Charlton
Once a leak has been fixed, people often ask whether the roof is still wet. A thermal survey with moisture readings can show whether wet areas remain, given suitable conditions on the day.
Most people get in touch when they’ve noticed something like this:
- Water that travels before it shows
- Areas of a flat roof that may hold water
- Water getting in at parapets and stacks
- Damp patches with no obvious cause
If you own one of the older houses in the streets near The Parish Church of the Blessed Virgin Mary, 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.
Choosing a roof surveyor

- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether the loft is part of the inspection
- What the report includes, and whether it has photographs
About our thermal roof survey in Charlton
On a flat roof, wet insulation holds heat longer than dry insulation. So a wet patch can show as a warmer or cooler area on the camera. It helps us see how far water may have spread under the covering, which is hard to judge by eye. We then check those areas with moisture readings. Typical surveys look at leaks far from where the stain appears and areas losing heat at the eaves and junctions, across ceilings below the roof, commercial roofs and pitched roof slopes.
Older buildings in small places like Charlton may be listed or in a conservation area. A look by drone or thermal camera doesn’t touch the roof, which suits a building where any change needs care. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
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.

Why it’s worth a survey now in Charlton
Once insulation under a membrane is wet, it tends to stay wet. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. Older cottages and farmhouses around Charlton can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, which starts from £400, inc. VAT. We can help you choose the package that fits what you need to know.

- Satisfaction rate of 98%
- Over 5,000 surveys carried out

Thermal roof surveys in Charlton: local notes
With West Dean House about 1.7 miles west, Charlton sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. Some old buildings in Sussex have Horsham stone slab roofs. Steep or complicated roofs are often hard to see from the ground, which is where photos from the air and thermal images help.
For site and facilities teams at buildings such as Singleton CofE Primary School, big roofs are where close-up aerial shots and thermal images show the most at once.

Charlton questions
Is Charlton within the area you cover?
We do. Villages and rural addresses get the same survey as a town house.
Does a conservation area affect roof work in Charlton?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
How do I book a survey in Charlton?
To book, phone 07833 053749 or drop us an email with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.

How many surveys have you done?
We’ve completed more than 5,000 surveys, across 20+ years of surveying roofs, and 98% of clients are satisfied.
Which survey includes thermal imaging?
Thermal imaging is included in our Premium Survey, from £400. That also includes a full inspection, a drone inspection where it applies, structural analysis and a same-day report.

Before and after the survey
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Some tips:
- Check from ground level or a window, never by climbing
- Note where damp appears and after what weather
- Take photos of stains as they appear, so we can compare
- Remember the conditions on the day affect the results
Where a pattern can’t be confirmed, the report says what could help, for example electronic leak detection or a roofer opening up a small section.
Clear outlets and gutters regularly, so water doesn’t sit on the roof. Less standing water means less chance of it getting under the covering.
How it works
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will get on with the inspection. The survey itself takes about one to two hours for a house, rising to roughly 3–4 hours on a commercial building. Older roofs in small places like Charlton can have low, tight loft spaces, so tell us about the loft hatch and any ladder. We only go where it’s 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.
- Patterns that stand out are checked with moisture readings.
- 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
- Make sure the loft hatch can be reached
- Keep pets in another room

What this survey can’t tell you
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Structural calculations, which need a structural engineer
- Hidden layers that need to be opened up to check
- Reliable images in rain, strong wind or on a wet roof surface

Where a roof is shared: we need access agreed with whoever owns or manages the building. Tell us about it as you book and we will plan the visit with that in mind.
We survey roofs for landlords and letting agents as well as householders. A written report with photographs gives you a clear record of the roof, which helps you plan work between tenancies.
