Thermal roof survey in Chelmsford
Thermal imaging can also show where a roof is losing heat. Gaps in loft insulation and poorly insulated areas can stand out on the images. It works best when the building is heated and it is colder outside. Our report points out what the images suggest and where to look more closely. We do not give energy ratings or heat loss calculations. We survey pitched roof slopes, commercial roofs and insulated roof spaces, and people most often book us about damp that repairs haven’t cured and ceilings that feel colder in places.
A place the size of Chelmsford has flats, offices, shops and schools with flat or low-pitched roofs. Water trapped under a flat covering can spread well beyond where it got in. Aerial photos show the whole roof at once, and anything a thermal image suggests is checked with moisture readings. Plant, rooflights and fragile panels can make a large roof unsafe to walk on.
The report works through the roof section by section, from the coverings down to the gutters. You’ll see the good as well as the bad.

Your questions about thermal roof surveys in Chelmsford
Is Chelmsford in the area you cover?
Yes. We survey roofs across London and the South East, and Chelmsford is part of that. You can phone 07833 053749 or send us an email with the address and a few details, and we will talk through which survey suits.
Is there anything to prepare before you come to Chelmsford?
Not much. Unlock side gates, keep pets in another room and dig out any invoices from past roof work.
Can a thermal survey trace a roof leak?
Thermal imaging can help, alongside other checks. The results depend on conditions on the day. Where it can’t be pinned down, the report suggests a next step, such as electronic leak detection.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Do you climb onto every roof?
Only where it is safe to do so. We look at everything that can safely be seen: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. Anything we can’t see is noted in the report.
Can you do a thermal survey in any weather?
The weather makes a real difference. It works best after a sunny day, with a dry roof surface and little wind. Rain and strong wind can make the images less clear, so we discuss the forecast when booking.
Are you structural engineers?
No. Visible signs such as deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.

What you can safely check yourself
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
Do you need a thermal roof survey in Chelmsford?
Buyers sometimes want more than a visual look at the roof. A Premium Survey adds thermal imaging, a drone inspection where applicable and a same-day report, which suits a purchase that’s moving quickly.
These are some of the problems a survey can pick up:
- Patches of heat loss across the roof
- Possible trapped moisture under a flat roof covering
- Damp around roof outlets and upstands
- Damp around chimneys and parapets
For businesses in and around places such as Bond Street Chelmsford, big, flat commercial roofs are where photos from the air and thermal images help most.
Before booking anyone

- Whether the price includes VAT
- Which limits apply to the survey
- How long they’ve been surveying roofs
Why get it checked now?
Trapped water can harm decks, timbers and ceilings the longer it stays. Looking now, while the damage may still be limited, keeps more options open. Whatever the age of a roof in Chelmsford, small defects only grow if they’re left. A loose ridge, a cracked flashing or a blocked outlet is a small job today and a bigger one after a wet winter.
Our price is from £400, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we’ll tell you which fits.

How the survey changes by roof type
Single-ply and EPDM roofs
On big single-ply roofs, the camera helps show where to take readings. That makes the survey more focused.
Pitched slate and tile roofs
From inside the loft, the camera can help with damp around chimneys, valleys and roof windows. Findings are checked with moisture readings.
Flying and imaging in Chelmsford
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. In Essex, older buildings are often clay-tiled, many with weatherboarding, and plenty of post-war and modern estates besides. Many roofs like these cannot be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place.
If yours is one of the older homes in the streets near Church of the Holy Trinity, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view by drone or thermal camera helps. Historic houses like Hylands, about 2.8 miles south-west, show how far back building around Chelmsford goes. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings.

How the survey works
Every roof is different; as a rough guide, the survey takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. If you have questions on the day, just ask. If the property is near the centre of Chelmsford, let us know about car parks or permit rules nearby. Inside, the loft and any room with a stain are the places we’ll want to see. Outside, we work round the building to find the safe viewpoints.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
Before the survey
- For a flat or shared roof, check access with the building owner or managing agent
- Make sure we can get to the back of the property
- Show us where any leaks or stains appear
