Sheerwater Thermal Roof Survey
Thermal roof surveys in Sheerwater from an independent, experienced roof surveyor. Over 5,000 surveys and 20+ years behind us across London and South East England.
- Thin or uneven insulation in the roof
- Water that travels before it shows
- Damp that repairs haven’t cured
How a thermal roof survey works in Sheerwater
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. It’s important to know that the camera shows temperature, not water, so findings are checked with moisture readings. It comes as part of our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. Typical surveys look at gaps in loft insulation and water that travels before it shows, on commercial roofs, flat roofs and insulated roof spaces.
Some older homes in villages like Sheerwater are listed or in a conservation area. A look from above or with a thermal imager does not touch the roof, which suits a building where any change needs care. Check with the council before planning any work on a listed building or one in a conservation area.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Signs you need a thermal roof survey in Sheerwater
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.
These are some of the problems a survey can pick up:
- Wet insulation beneath the membrane
- Thin or uneven insulation in the roof
- Wet areas near outlets and upstands
- Patches of heat loss across the roof
The streets around a church such as St. Michaels Church are frequently among the oldest in a place, and if you own one of the older houses nearby, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Before you book any roof surveyor
- Whether you can ask questions once you have the report
- What experience they bring
- Their drone registration, if they fly one
- Is VAT included in the price?
What a survey costs
A few things affect what a survey costs:
- Chimneys, valleys, parapets and other details
- The height of the building and how the roof can safely be seen
- The number of roofs, including extensions and garages
- The use of thermal imaging or a drone
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Thermal roof survey starts from £400, including VAT.
What to tell us when you get in touch
Some details help us point you to the right survey and price. When you get in touch, it helps to mention:
- The type of building and roof, like pitched or flat
- Where the property is, with the postcode
- How the loft is reached, if there is one
- What made you get in touch
Once you know what you need, phone 07833 053749 or email us. From there it is a case of choosing a package, agreeing the price and fixing a day, weekday or weekend.
Sheerwater questions
Will you come out to Sheerwater?
Yes, Sheerwater is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Are there drone restrictions around Sheerwater?
Typically it comes down to two things: the airspace at the address and the weather. Sheerwater is about 2 miles from Fairoaks Airport, so the Drone Safety Map is checked for restrictions around it before we fly. The flight also waits for calm, dry weather, and the rest of the survey does not depend on the drone.
How does a thermal imaging roof survey work?
The images show how warm or cool each part of the surface is. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, which we then check with moisture readings.
What insurance do you have?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
Is thermal imaging useful on pitched roofs?
It can help, but the results are often less clear than on a flat roof. The air space under slates and tiles can hide patterns, so we combine it with an inspection from the loft where there’s safe access.
Will you go up on the roof?
Only if it is safe. We look at everything that can safely be seen: from the ground, from windows, from inside the loft space, from the roof where it is safe and by drone where it applies. The report says if anything couldn’t be seen.
How many surveys have you done?
Over 20 years and more than 5,000 surveys.

For landlords and managing agents
Letting agents can arrange access with tenants, at a time agreed ahead of time. We survey on any day of the week, which can make access easier.
Letting agents frequently book on a landlord’s behalf, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
The survey, step by step
We look at the roof from outside and, where it’s relevant and there is safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement. The whole visit usually takes about one to two hours for most homes, plus time to check any thermal findings with moisture readings. Somewhere like Sheerwater needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect what can be seen safely, inside and out.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We look at the roof from ground level, from windows and from the roof itself where it is safe.
- A thermal camera records how the surface temperature varies across the roof.
- We check the patterns that stand out with moisture readings where there is safe access.
- You get a report with thermal images, photographs and our recommendations.
Before the survey
- For flats, make sure roof access has been agreed
- Check pets are kept safely away
- Point out any leaks or damp patches
How to book
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just ring 07833 053749 or drop us an email when you are ready.

GRP fibreglass roofs
Water under a GRP roof can reach the timber deck. The camera can help show where to look.
Felt and asphalt flat roofs
Felt and asphalt sit tight to the layers below, which frequently helps the camera pick up differences. Any patterns are checked with moisture readings.
Thermal roof surveys in Sheerwater: local notes
Historic houses such as Botleys Mansion, about 2.8 miles north, show how far back building in the area around Sheerwater goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
For site and facilities teams at buildings such as Broadmere Primary Academy, a view from above covers a wide roof far faster than walking it. Shop and office owners around The Peacocks may find that big, flat commercial roofs are where close-up aerial shots and thermal images help most.

Why it is worth a survey now in Sheerwater
Heat lost through a roof costs money every winter. Thermal images can show where insulation is missing or has slipped, so improvements can go where they’re needed. Matching old materials, such as handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, all inc. VAT. What your roof costs depends on its size, access and what you want to find out.
Why us?
- Clear package prices, including VAT
- Drones and thermal imaging where applicable
- Drone flown under a CAA Flyer ID and Operator ID
- An independent view of the roof
