North Holmwood Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof for North Holmwood, from an experienced roof surveyor. You get a clear written report with photographs.
- Thin or uneven insulation in the roof
- Ceilings that feel colder in places
- Heat escaping through the roof
Thermal roof survey in North Holmwood: what you get
On a flat roof, wet insulation holds heat longer than dry insulation. That means a wet area can show up as a different temperature from the rest of the roof. This can give an idea of how far water has travelled beneath the membrane, something you can’t normally tell from the surface. We then check those areas with moisture readings. Common reasons to book are ceilings that feel colder in places and missing or slipped insulation, across loft conversions, pitched roof slopes and commercial roofs.
Around North Holmwood, lots of roofs are low enough to see partly from the garden or the street. The parts you can’t see, like rear slopes, valleys and chimney tops, are where a drone or thermal camera adds detail. The forecast decides the day. Close-up images often show wear on ridges, verges and flashings that can’t be judged properly from the ground.
We write the report in plain English, so it makes sense without any roofing background. Photographs show what each point refers to, with the urgent items made clear.

When to book a survey in North Holmwood
Unexplained damp is one of the main reasons people ask for thermal imaging. Water can travel under a roof covering or along timbers before it shows inside. The camera helps narrow the search.
These are some of the problems a survey can pick up:
- Areas losing heat at the eaves and junctions
- Water that travels before it shows
- Gaps in loft insulation
- Moisture around outlets and upstands
Anyone responsible for a site like St John's Church of England Primary School will know that thermal images can show where wet insulation sits under a big flat roof.
Before you book any roof surveyor
- Will they check the loft as well as the outside?
- What insurance they carry
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether you get a written report with photos
How the survey changes by roof type
Loft insulation
Loft insulation is easily disturbed when people store things or run cables. Thermal images can show where it has been pushed aside.
Single-ply and EPDM roofs
Many single-ply and EPDM roofs sit on insulation boards. Wet boards can show as temperature differences on the images.

The survey, step by step
There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. A typical survey takes an hour or two at most homes, and longer for a large or complex roof. A visit to North Holmwood is planned like any other: the time, the access and where to park are agreed in advance. Weekday and weekend visits are both possible. Tell us about any garages, outbuildings or extensions you want included.
- First we discuss the roof, any damp and the forecast for the visit.
- 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.
- We take moisture readings where the images suggest a problem.
- The report pairs each thermal image with a photo and explains what it suggests.
Before the survey
- Tell us about any leaks, stains or damp patches you know of
- Keep pets inside or away from the areas we are looking at
- Make a note of anything you’d like us to look at

Advice
North Holmwood: your questions answered
Is North Holmwood within the area you cover?
Yes, North Holmwood is on our map. A small place gets exactly the same survey as a big one.
Do you carry out roof surveys in North Holmwood?
Yes, North Holmwood is one of the places we work. The survey and report are the same in North Holmwood as anywhere else.
Will thermal imaging find my leak?
It’s a useful tool for tracing leaks, but not the only one. The results depend on conditions on the day. If the source cannot be confirmed, we will say what could help next, such as electronic leak detection.
How does a thermal imaging roof survey work?
A thermal camera shows differences in surface temperature. Those patterns can point to trapped moisture, missing insulation or heat loss. Findings are checked with moisture readings.
How do I arrange a thermal roof survey in North Holmwood?
To arrange a survey, call 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
Can thermal imaging show missing insulation?
Thermal images can suggest where heat is escaping and where insulation may be missing. We do not give energy ratings or heat loss calculations, but the report shows where to look more closely.
When does the report arrive?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
Practical tips
You do not need to be a roofer to help. What helps most:
- Do not climb onto the roof to look for leaks yourself
- Keep the heating on as usual before a heat loss survey
- Ask us about the forecast if rain is expected
- File the images with your roof records
After the visit, we put the thermal images, photographs and moisture readings into one report. Each image is explained in plain words, with our recommendations. Premium reports are sent the same day.
Keep outlets and gutters clear so water drains off the roof quickly. Less standing water means less chance of it getting under the covering.
