Thermal roof surveys for homes and businesses in Twickenham
Wet insulation under a flat roof covering holds heat for longer than dry. So a wet patch can show as a warmer or cooler area on the camera. It helps us see how far water may have spread under the covering, something you cannot typically tell from the surface. Moisture readings are then used to check what the camera suggests. If you are worried about damp around roof outlets and upstands and wet insulation beneath the membrane, a survey will tell you what’s going on, whatever the roof.
Many London roofs are hidden from the pavement: butterfly roofs behind parapets, dormer tops and flat roofs over back additions. That is where a view from the air or a thermal camera helps, by showing what cannot be reached safely. Weather on the day decides whether it goes ahead, in Twickenham as anywhere. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
It is not only a list of defects. It explains what we found, why it matters and what we recommend.

Questions from Twickenham
Can parking be tricky for a visit in Twickenham?
It rarely stops a survey, but it’s worth planning. Tell us what parking is available nearby, and the visit is planned around it.
Can you fly a drone over a roof in Twickenham?
The answer turns on the exact location and the conditions on the day. Twickenham is about 2 miles from the edge of the flight restriction zone around Heathrow Airport. The exact boundary is checked for each address before any flight, and a roof inside it needs permission before we fly. London’s airspace includes flight restriction zones around Heathrow, London City Airport and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. The flight also waits for calm, dry weather, though the rest of the survey goes ahead either way.
How soon will I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, let us know as you book.
Can you use a thermal camera on a sloping roof?
It can show heat loss and some damp, but it has more limits there. Our report is clear about what can be read from them, and back them up with a visual inspection and moisture readings.
Does the report include photographs?
Yes. We photograph the roof as we go, and the report uses them to show each finding.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We are 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.
Are you structural engineers?
No. We note visible signs such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
What we’re asked to look at in Twickenham
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 suits a purchase that is moving quickly.
These are some of the problems a survey can pick up:
- Ceilings that feel colder in places
- Missing or slipped insulation
- Water getting in at parapets and stacks
- Possible trapped moisture under a flat roof covering
Richmond House, about 0.5 miles east, is one of the historic houses in the wider area around Twickenham. Photos from the air and thermal images let an old roof be checked without anyone disturbing it.

Airspace, weather and Twickenham roofs
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. The flight restriction zone around Heathrow Airport comes within about 2 miles of Twickenham. If the drone is used for your survey, the exact boundary is checked for the address first.
For businesses in and around places such as Treaty Centre, large commercial roofs are often easiest to see by drone or thermal camera. Controlled parking zones are common in London, so mention any permit rules for Twickenham.

Before and after the survey
Here are a few things we’d tell any owner, before and after a survey:
- Note where damp appears and after what weather
- Do not climb onto the roof to look for leaks yourself
- Remember the conditions on the day affect the results
- File the images with your roof records
Buyers can use the findings when talking to the seller or agent. What you do with it is up to you, whether that is asking for work or discussing the price.
Have small defects in the covering fixed early. Water that gets under a covering can spread a long way before it shows.
Checking the roof from ground level
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
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.

Rented homes, blocks and businesses
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps when budgeting.
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. Surveys run on any day of the week, which can make access easier.
The survey, step by step
After the inspection, everything we found is written up in a report with photos, sent to you by email. As for time on site, most surveys take between one and two hours at a typical home, with bigger or more complicated roofs taking longer. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when you book.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- 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.
Getting ready for the survey
- Have any questions written down, so nothing gets missed
- Let us know about parking before the day
- Check the loft hatch can be reached
