Croxley Green Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof in Croxley Green, carried out by an experienced roof surveyor. You get a clear written report with photos.
- Ceilings that feel colder in places
- Missing or slipped insulation
- Water getting in at parapets and stacks
Thermal roof surveys for homes and businesses in Croxley Green
A thermal survey can point to places where heat is escaping through the roof. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it is warm inside and cold outside. The report shows the images and explains what they may mean. We don’t give energy ratings or heat loss calculations. Common reasons to book are areas losing heat at the eaves and junctions and leaks that are hard to trace, across loft conversions, flat roofs and pitched roof slopes.
Somewhere as small as Croxley Green, older roofs are often steep and partly hidden by trees or outbuildings. Close-up drone photos and thermal images help show what cannot be reached safely. Both the forecast and the airspace are checked first. Steep slopes and tall chimney stacks are where a close-up view adds the most.
After the visit, you get a report with photographs, sent by email. It explains the condition of the roof, the defects we found and what we recommend.

DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Honest limits
A survey is a close look at the roof, but it can’t do everything. The main limits are:
- Confirming water without moisture readings
- The condition of timbers we cannot see
- Structural calculations, which need a structural engineer
If in doubt, phone 07833 053749 or send us an email and we’ll recommend the right survey before you book. What our survey covers.
What we check
- Insulated roof spaces
- Flat roofs
- Loft conversions
- Ceilings below the roof
- Pitched roof slopes
- Commercial roofs
Tips from our surveys
A few practical points come up again and again on our surveys. They apply to most roofs:
- Don’t switch the heating off ahead of the visit
- Make sure the loft can be reached safely
- Clear leaves from outlets and gutters each autumn
- Keep the report to compare against after any repair
Buyers can use the findings when talking to the seller or agent. It is your decision how to use it, whether that is asking for work or discussing the price.
Check loft insulation covers the whole area and hasn’t been disturbed. Gaps frequently appear after work in the loft.
Why act early in Croxley Green
Before replacing a large flat roof, it’s useful to know how much of it is actually wet. Thermal imaging, checked with moisture readings, gives a clearer picture before you spend. Older and listed buildings around Croxley Green may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
Prices quoted always include VAT, and the report isn’t charged as an extra. Our price is from £400, including VAT. Size, height and access decide where your roof falls.

How it works
The visit has one job: to see as much of the roof as can be seen safely and record it clearly. Everything we note and photograph goes into the written report. It usually takes an hour or two on an ordinary house, though large, tall or awkward roofs take more time. Somewhere as small as Croxley Green, access is frequently the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- 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.
- The report pairs each thermal image with a photo and explains what it suggests.
Preparing for the visit
- Unlock side gates and any roof access doors
- If you’re buying, check with the agent that we can get in
- Jot down any questions you want answered

Your questions about thermal roof surveys in Croxley Green
Does a conservation area affect roof work in Croxley Green?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is Croxley Green within the area you cover?
We do. A small place gets exactly the same survey as a big one.
Is this a RICS survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
Can you do a thermal survey in any weather?
The results depend on the weather. A dry surface, little wind and a sunny spell beforehand help most. We record the conditions in the report, so you know how much weight to give the images.
Can you use a thermal camera on a sloping roof?
On pitched roofs, the camera can point to heat loss and some damp patterns. Our report is clear about what can be read from them, and we check them with a visual inspection and moisture readings.
Can a thermal camera see water?
No, not on its own. It shows surface temperature, and wet areas can show up because they hold heat differently. That’s why we check any patterns with moisture readings.
How long have you been surveying roofs?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.
What we are asked to look at in Croxley Green
Buyers sometimes want more than a visual look at the roof. The Premium Survey brings thermal imaging and a drone inspection where it applies, with a report the same day, which helps when timescales are tight.
Things that frequently lead to a survey include:
- Patches of heat loss across the roof
- Damp that repairs haven’t cured
- Leaks far from where the stain appears
- Moisture around outlets and upstands
Chenies Manor House lies about 4.2 miles north-west, so building around Croxley Green goes back a long way. For older roofs nearby, a look by drone or thermal camera is a hands-off way to check condition.
Before booking any roof surveyor
- Their drone registration, if they fly one
- Whether the inside of the roof is included
- Is there a chance to talk the report through?
- What the report includes, and whether it has photographs
Drones, thermal imaging and Croxley Green roofs
If the drone is used for your survey, the flight is checked against the Drone Safety Map first. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
If you run a business near Charter Place, a commercial roof can be photographed from above without anyone walking on it. If you look after a building like Harvey Road Primary School, a drone or thermal camera can show a large roof in a single visit.
