Cosham Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof in Cosham. We’ve completed more than 5,000 surveys across London and South East England.
- Water getting in at parapets and stacks
- Cold areas below the roof
- Possible trapped moisture under a flat roof covering
What happens on the day
We do not take risks to get a closer look. Everything that can be seen safely is inspected, and if part of the roof cannot be seen, the report says so. The survey usually takes roughly 1–2 hours on an ordinary house, and about three to four hours for a commercial roof. With a bit of garden around a house, as there often is around Cosham, the roof can be viewed from several angles. Mention any side of the property we cannot get to. The loft, where there is safe access, completes the picture.
- You tell us about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Preparing for the visit
- Point out any leaks or damp patches
- Move anything stored under the loft hatch
- Have any questions written down, so nothing gets missed

Thermal roof surveys for homes and businesses in Cosham
Our Premium Survey, from £400, brings together a full roof inspection and thermal imaging. It also includes a drone inspection where applicable, a structural analysis and a same-day report. There’s an in-person consultation as well, plus a follow-up 12 months later. To book, just call 07833 053749 or use the contact form with the address and what you’ve noticed. Larger commercial roofs are quoted for their size. We’re frequently asked to look into wet areas near outlets and upstands and damp around chimneys and parapets, on commercial roofs, pitched roof slopes and flat roofs.
Even in a smaller place like Cosham, there may be airfields or restrictions nearby, so the Drone Safety Map is checked before any flight. Open ground can mean stronger wind, which also affects whether a small drone can fly. Neighbours’ privacy is part of planning each flight, along with the airspace and the weather.
Findings are set out part by part, from the coverings down to the gutters, with a note and a photo for each point. You will see the good as well as the bad.

Tips that help
You don’t need to be a roofer to help. What helps most:
- Check outlets after heavy rain
- Check from the ground or a window, never by climbing
- Take photos of stains as they appear, so we can compare
- Heat the home normally on the days before
After the visit, we put the thermal images, photographs and moisture readings into one report. We explain what each image may mean, with our recommendations. With a Premium Survey, you get the report the same day.
Have small defects in the covering fixed early. Water that gets under a covering can spread a long way before it shows.
Different roofs, different checks
GRP fibreglass roofs
Water under a GRP roof can reach the timber deck. Thermal imaging can suggest where that may be happening.
Pitched slate and tile roofs
Slate and tile roofs are often harder to read with a thermal camera, because of the air space beneath. We back up what the camera shows with a look in the loft where we can.
Cosham: your questions answered
How do I find out if my home in Cosham is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you cover smaller places like Cosham?
Yes, we do. Our area covers London and the South East, and smaller places are part of that. Longer journeys are simply planned ahead of time.
What’s the best way to book?
The quickest way is to call 07833 053749 or email us. Give us the address and a few details about the roof, and we will take it from there. Surveys run on weekdays, Saturdays and Sundays.
Does thermal imaging work on slate and tile roofs?
On pitched roofs, the camera can point to heat loss and some damp patterns. We explain what the images can and can’t tell you, and we check them with a visual inspection and moisture readings.
Will you go up on the roof?
Only if it’s safe. We inspect whatever is safely visible: from the ground, from windows, from inside the loft space, from the roof where it’s safe and by drone where applicable. Anything we can’t see is noted in the report.
How much does a thermal roof survey cost?
It is part of the Premium Survey, from £400. You also get an in-person consultation and a 12-month follow-up. Larger commercial roofs are quoted for their size.
How long does the survey take?
It usually takes an hour or two for most houses, and about three to four hours for a commercial roof. The report follows by email.
What affects the cost of thermal roof surveys
All our prices include VAT. The things that change the price are:
- Any need for thermal images or a drone flight
- Commercial roofs and larger buildings
- Height and safe access
- The number of roofs, including extensions and garages
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Our price is from £400, including VAT.
What to let us know when you get in touch
To price your survey accurately, we’ll ask about:
- What kind of property and roof it is
- What’s prompted the survey
- Where water is showing inside, if it is
- Where the property is, with the postcode
Thermal roof survey starts from £400, including VAT. The exact figure depends on the roof and the package, so ring 07833 053749 or email us with the details.
Thermal roof surveys around Cosham
The coast is about 1 mile or less from Cosham, and coastal wind can be strong. Clear thermal results need a dry roof and little wind after a sunny day, so the date depends on the forecast. If your survey includes the drone, we check the Drone Safety Map for restrictions before flying.
If you look after a shop, office or commercial unit, for instance near Tricorn Centre, big, flat commercial roofs are where close-up aerial shots and thermal images help most. If yours is one of the older homes in the streets near Church of St Philip, older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help. For site and facilities teams at buildings like Court Lane Junior Academy, a view from above covers a wide roof far faster than walking it.

For landlords and managing agents
Any of our surveys can be booked by landlords, agents and building managers in Cosham. For a price for a let property or a block, ring 07833 053749 or use the contact form.
Letting agents can arrange access with tenants, at a time agreed ahead of time. We survey on weekdays, Saturdays and Sundays, which can make access easier.
Can I check my roof myself?
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we check the roof.
