Cannon's Green Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof in Cannon's Green, carried out by an experienced roof surveyor. Every survey comes with a written report and photos.
- Moisture around outlets and upstands
- Cold areas below the roof
- Water getting in at parapets and stacks
Thermal roof survey in Cannon's Green: what you get
A thermal survey isn’t a quick fix for every roof problem. Sun, shade, reflective surfaces and wind can all change what the camera shows. That’s why we check findings with moisture readings and a close visual inspection. Our report says plainly what the camera picked up and how sure we can be. Where something can’t be confirmed, we say what would help next. We’re often asked to look into wet insulation beneath the membrane and ceilings that feel colder in places, across pitched roof slopes, loft conversions and commercial roofs.
Older buildings in small places like Cannon's Green may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, so it is a gentle way to see the condition of an old roof, before anyone decides what work it needs. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

When to book a survey in Cannon's Green
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, given suitable conditions on the day.
A survey makes sense if you’ve noticed:
- Thin or uneven insulation in the roof
- Damp where roofs meet walls and chimneys
- Areas losing heat at the eaves and junctions
- Ceilings that feel colder in places
For site and facilities teams at buildings like The Ongar Academy, big roofs are where photos from the air and thermal images show the most at once.
Before booking anyone
- Whether they hold professional indemnity and public liability insurance
- Whether you get a written report with photos
- How soon the report will arrive

Airspace, weather and Cannon's Green roofs
Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying. Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, and a good many post-war and modern estates besides. Steep or complicated roofs are often hard to see from the ground, which is where aerial photos and thermal images help.
The streets around a church such as Church of St Nicholas are often among the oldest in a place, and if your home is one of the older ones nearby, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image.

- Structural calculations, which need a structural engineer
- Clear results when the conditions on the day are poor
- An energy rating for the building

Your questions about thermal roof surveys in Cannon's Green
Do you cover smaller places like Cannon's Green?
Yes, smaller places are covered as well as towns. We survey roofs across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is my home in Cannon's Green listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
What will the report tell me?
A report with photographs, explaining the condition of the roof, any defects and our recommendations, by urgency where it matters. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where it applies and structural analysis.
Do you take photos of the roof?
Yes. We photograph the roof as we go, and the report uses them to show each finding.
What conditions are best for thermal imaging?
Conditions on the day have a big effect on what the camera can show. Dry, calm weather after some sun gives the best chance of clear images. Our report notes the conditions and how they affected the findings.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when you book.
Is thermal imaging good for finding leaks?
It is a useful tool for tracing leaks, but not the only one. What it shows depends on the weather and the roof. If the source can’t be confirmed, we will say what could help next, such as electronic leak detection.
What happens if roof problems are left?
Without thermal imaging, the only way to see how far water has spread is frequently to open up the roof. It helps when deciding whether to patch an area or replace the roof. Older cottages and farmhouses around Cannon's Green 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.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.

The survey, step by step
The visit has one job: to look at the roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It typically takes about 1–2 hours for a house, while a commercial roof takes nearer three to four hours. In a hamlet or village like Cannon's Green, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- You let us know about the roof and any damp, leaks or cold rooms.
- 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.
- The Premium report reaches you the same day, and we go through it with you in person.
Preparing for the visit
- Tell us about parking before the day
- If you’re buying, let the agent know when we are coming
- Gather any invoices or paperwork from past roof work
Booking a survey
If you have photos of the roof, send them over. Pictures from ground level or a window are fine, and please do not climb up for a closer look. To get started, call 07833 053749 or drop us an email.

Tips that help
A few practical points come up again and again on our surveys. They apply to most roofs:
- Clear leaves from outlets and gutters each autumn
- Keep a record of when stains appear
- Check from the ground or a window, never by climbing
- Check the loft can be reached safely
Once we’ve been, the thermal images, photos and readings go into a single report. Each image is explained in plain words, alongside what we recommend. Premium reports are sent the same day.
Clear outlets and gutters regularly, so water does not sit on the roof. The less water sits, the less can find its way beneath.
What you can safely check yourself
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
