Catherington Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof across Catherington, using drones and thermal imaging where it applies. Get in touch for a price.
- Damp that repairs haven’t cured
- Heat escaping through the roof
- Damp around roof outlets and upstands
Why act early in Catherington
Once insulation under a membrane is wet, it tends to stay wet. Over time, it insulates less well and can harm the deck. Finding the wet areas sooner keeps the work smaller. Around Catherington, older homes often have old roof timbers, and water through a failed covering can rot timber if it is left.
Thermal roof survey starts from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included, and we’ll tell you which fits.

About our thermal roof survey in Catherington
What a thermal camera can show depends a lot on the weather. A sunny day before the survey, a dry roof surface and little wind all help. Rain, a strong wind or heavy cloud can make the images less clear. We will discuss the weather with you when booking, and the report explains how the conditions on the day affected the results. We are often asked to look into wet insulation beneath the membrane and cold spots on ceilings under the roof, across commercial roofs, loft conversions and flat roofs.
In a small place like Catherington, open ground can mean strong wind. Strong wind or heavy rain stops a small drone flying, and calm conditions also suit thermal imaging best. We plan the journey, access and timing around the weather. If the day turns windy or wet, the visit can be moved.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

What we’re asked to look at in Catherington
People often book a thermal survey when a damp patch has no obvious cause. A leak may start well away from where the stain appears. Temperature patterns can help narrow down where to look.
Typical things we’re asked to look at include:
- Possible trapped moisture under a flat roof covering
- Damp around roof outlets and upstands
- Damp around chimneys and parapets
- Patches of heat loss across the roof
For site and facilities teams at buildings such as Catherington Church of England Infant School, a drone or thermal camera can show a large roof in a single visit.
What to check before booking
- What the report includes, and whether it has photographs
- What they won’t be able to tell you
- How long the report takes to arrive
- Whether the loft space is looked at, where there is one
Roof by roof
Single-ply and EPDM roofs
Thin membranes can show patterns from the layers beneath. Reflections from shiny surfaces can affect readings, which we allow for.
Parapets, valleys and junctions
Water frequently gets in where roofs meet walls, parapets or valley gutters. The camera can help show damp around these junctions.
FAQs for Catherington
Do you cover Catherington?
We do. Every survey there gets the same written report with photos.
Is my home in Catherington listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
How long does the survey take?
Expect it to take about 1–2 hours for most houses, and longer for a large or complex roof. You’ll then get the report by email.
Does the report include photos?
Yes. Photographs are taken throughout the survey, and they go into the written report.
Is thermal imaging useful on pitched roofs?
It can be useful, though pitched roofs are usually harder to read. The air space under slates and tiles can hide patterns, so we also look from the loft where it’s safe.
Can a thermal camera see water?
Thermal imaging shows temperature rather than water. Wet insulation holds heat longer than dry, so it can stand out, and moisture readings are used to check it.
Will thermal imaging find my leak?
It can help narrow down where water may be getting in. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. It’s used alongside a close inspection and moisture readings because the camera can’t confirm water on its own.
How it works
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey normally takes roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Cottages and farmhouses around Catherington often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- A full inspection and thermal imaging are carried out together.
- We back up the thermal patterns with moisture readings.
- You get the report the same day, with an in-person consultation to follow.
Before the survey
- Leave a clear route to the loft
- Unlock side gates and any roof access doors
- Buyers: confirm access with the estate agent or seller
Arrange a survey
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just ring 07833 053749 or use the contact form when you’re ready.

Checking the roof from the ground
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
What you can’t do safely is get up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where applicable.

It’s a careful look at the roof, not the whole story. The main limits are:
- Confirming water without moisture readings
- Reliable images in rain, strong wind or on a wet roof surface
- Insulation values or heat loss calculations

What a thermal roof survey looks like in Catherington
Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned. Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying.
The streets around a church such as Church of All Saints are frequently among the oldest in a place, and if your home is one of the older ones nearby, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
