Thermal Roof Survey in Lightwater
Thermal imaging to find moisture and heat loss patterns in a roof in Lightwater, carried out by an experienced roof surveyor. You get a clear written report with photos.
- Wet insulation beneath the membrane
- Damp patches with no obvious cause
- Damp where roofs meet walls and chimneys
How it works
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. The inspection then takes about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Some parts of a survey depend on the weather, so a visit to Lightwater is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- We check the roof from ground level, from windows and from the roof itself where it’s safe.
- A thermal camera records how the surface temperature varies across the roof.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- The report sets out the images, what they suggest and what we recommend.
Preparing for the visit
- Check we can get to the back of the property
- Point out any leaks or damp patches
- If you’re buying, let the agent know when we are coming
Booking a survey
Photos help, if you have them. Take them safely from ground level or a window. To send them or to book, call 07833 053749 or use the contact form.

Thermal roof survey in Lightwater: what you get
On a flat roof, wet insulation holds heat longer than dry insulation. So a wet patch can show as a warmer or cooler area on the camera. This can give an idea of how far water has travelled beneath the membrane, something you cannot normally tell from the surface. Moisture readings are then used to check what the camera suggests. If you are worried about areas of a flat roof that may hold water and leaks that are hard to trace, a survey will tell you what’s going on, on ceilings below the roof, commercial roofs and insulated roof spaces alike.
Places like Lightwater can be near small airfields or other airspace restrictions, so every drone flight starts with a check of the Drone Safety Map. 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.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Airspace, weather and Lightwater roofs
Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Many roofs like these can’t be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place. Before planning roof work on an older home, find out whether it is listed or in a conservation area. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
If you look after a building such as Hammond School, a view from above covers a wide roof far faster than walking it.
Lightwater is about 3 miles east of Camberley, in Surrey. We provide thermal roof surveys for homes and businesses in Lightwater. We cover towns and villages across Surrey, large and small. You can also see our page for Guildford.
Every address in GU18 and GU19 is within our area for thermal roof surveys, from the main roads to the quietest streets. Streets in the area include Ambleside Road, Ridgeway Close and Shrublands Drive, and we cover them all. Nearby, we also carry out thermal roof surveys in Donkey Town (1 mile south-east), Bagshot (1 mile north-west), Windlesham (1 mile north-east), Lucas Green (2 miles south-east) and West End (2 miles south-east). Further out, we also cover Guildford (8 miles south-east), Woking (5 miles south-east), Camberley (3 miles west), Farnham (11 miles south-west), Egham (8 miles north-east) and Walton-on-Thames (12 miles east).
What’s near Lightwater
Typical jobs here are in homes near Gordon's School and Brentmoor Heath. Lightwater’s nearest station is Bagshot station, roughly 1.3 miles north-west of the centre. Nearby you’ll also find Brookwood Hospital (3.3 miles south-east) and The Museum of The National Rifle Association (2.7 miles south). Open spaces near Lightwater include Brookwood Lye.
What affects the cost of thermal roof surveys
Prices vary from roof to roof, for these reasons:
- The number of roofs, including extensions and garages
- The type of building, from a house to a block or an office
- Roof area
- The height of the building and how the roof can safely be seen
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all inc. VAT. Size, height and access can affect the price too.
Getting in touch
What helps most when you contact us:
- Where the property is, with the postcode
- Anything about access we should know
- Your timetable, such as an exchange date
- Pictures of the roof from a safe spot, if you have them
A quick phone call is normally the easiest start: phone 07833 053749 or send us an email and we will ask a few questions about the roof. The price is agreed before a date is set.
Surveys for landlords and agents in Lightwater
With a portfolio of properties, surveys can be booked for more than one address. To arrange surveys for several addresses, ring 07833 053749 or email us with the addresses.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out in order of urgency where relevant.
Common roof problems in Lightwater
Some defects simply can’t be seen with the eye. Wet insulation, gaps in insulation and heat loss are frequently invisible from outside. Thermal imaging gives us another way to look for them.
These are some of the problems a survey can pick up:
- Water that travels before it shows
- Areas losing heat at the eaves and junctions
- Wet areas near outlets and upstands
- Damp that repairs haven’t cured
For an older house near a landmark such as All Saints, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view from the air or with a thermal camera helps.
Before booking any roof surveyor
- Whether you get a written report with photos
- Whether VAT is added on top
- Which parts of the roof they’ll actually see
- What follow-up you get after the report
Roof by roof
GRP fibreglass roofs
GRP surfaces can be shiny, which affects thermal readings. We take that into account and check findings with moisture readings.
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.
Questions from Lightwater
Do you carry out roof surveys in Lightwater?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is my home in Lightwater listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Do I need to be at home?
Not necessarily. If we only need the outside, we can agree that beforehand, but anything inside needs someone there to give access.
Can a thermal camera see water?
Thermal imaging shows temperature rather than water. Wet insulation holds heat longer than dry, so it can stand out, but we check each finding with moisture readings.
Will thermal imaging find my leak?
It can help narrow down where water may be getting in. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. We combine it with a visual inspection and moisture readings, as the camera alone can’t prove a leak.
Do you take photos of the roof?
Yes, every report has them. Pictures sit next to the findings they show, so you can see what we mean.
Can you check my loft insulation with a thermal camera?
Gaps and thin areas of insulation can show up on the camera. The difference is clearest when the building is heated and it is colder outside. Where we can reach the loft safely, we check there too.
Before and after the survey
There is plenty you can do without going near the roof. Here’s what helps most:
- Keep outlets and gutters clear to stop water sitting
- Move stored items away from the loft hatch
- Use the report as a baseline for later checks
- Note where damp appears and after what weather
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it is easy to find each area on the roof.
After repairs or a new covering, a later survey can confirm things are dry in suitable weather.
