Lower Bourne Thermal Roof Survey
Find out the condition of the roof at your property in Lower Bourne from an independent roof surveyor. We visit on weekdays and at weekends.
- Damp patches with no obvious cause
- Water getting in at parapets and stacks
- Areas of a flat roof that may hold water
Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
Thermal roof survey in Lower Bourne
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. Patterns can suggest where water is trapped under the covering. Pitched roofs with slates or tiles are often harder to read, because of the air space beneath, so we combine the camera with an inspection from the loft where there is safe access. Typical surveys look at ceilings that feel colder in places and patches of heat loss across the roof, across pitched roof slopes, ceilings below the roof and loft conversions.
Around Lower Bourne, plenty of roofs are low enough to see partly from the garden or the street. Chimney tops, valleys and rear slopes are where close-up or thermal images help most. Both depend on the weather on the day. Even so, a close-up image often shows wear on ridges and flashings that a view from the ground misses.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

Thermal roof surveys in Lower Bourne: local notes
About 1.6 miles north lies Farnham Castle, a reminder of how long the area around Lower Bourne has been built on. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail.
For site and facilities teams at buildings such as Farnham College, big roofs are where close-up aerial shots and thermal images show the most at once.
Lower Bourne is about 1 mile south of Farnham, in Surrey. We carry out thermal roof surveys for homes and businesses in Lower Bourne. Our area takes in places right across Surrey. You can also see our page for Guildford.

What we look for on each type of roof
Parapets, valleys and junctions
Damp at junctions can be hard to see by eye. A careful visual inspection goes alongside the images.
Single-ply and EPDM roofs
Single-ply PVC, TPO and EPDM roofs are often laid over insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
What happens on the day
The visit usually starts outside and finishes in the loft: outside views come first, then the loft space if there is safe access. All told, expect an hour or two at a house, including the thermal images, and around 3–4 hours for a commercial roof. With a bit of garden around a house, as there often is around Lower Bourne, the roof can be viewed from several angles. Mention any side of the property we can’t get to. Inside, the loft is checked where it can be reached safely.
- You let us know 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.
- The Premium report reaches you the same day, and we go through it with you in person.
Before the survey
- Dig out any old roof reports or invoices
- Agree roof access with the managing agent if it’s shared
- Let us know about any leaks, stains or damp patches you know of

Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Clear results when the conditions on the day are poor
- What’s inside walls or under coverings, without opening up
- A structural engineer’s assessment

A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client.

Common questions in Lower Bourne
Does a conservation area affect roof work in Lower Bourne?
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 Lower Bourne within the area you cover?
Yes. Lower Bourne is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and South East England. Let us know about access, parking and anything unusual about getting there when you book.
What’s in the report?
You get our findings in writing, part by part, with photos, finishing with recommendations. The most urgent items are made clear.
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’s colder outside. Where we can reach the loft safely, we check there too.
What does a thermal roof survey show?
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 conditions are best for thermal imaging?
The weather makes a real difference. A sunny day beforehand, a dry surface and calm air all help. Rain and strong wind can make the images less clear, so we discuss the forecast when booking.
Can you give me structural calculations?
No. We are roof surveyors, not structural engineers. If we see signs that need an engineer’s opinion, we’ll recommend one.
What we are asked to look at in Lower Bourne
Building owners and managing agents use thermal surveys to plan work on larger flat roofs. It can suggest which areas may be wet and which seem dry, so moisture readings can be targeted.
These are some of the problems a survey can pick up:
- Thin or uneven insulation in the roof
- Damp where roofs meet walls and chimneys
- Cold spots on ceilings under the roof
- Damp around roof outlets and upstands
The streets around a church such as St Martin by the Green are often among the oldest in a place, and if your house is among the older ones nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view from above or with a thermal imager helps.
What to check before booking
- Their report turnaround times
- Which viewpoints they use to see the roof
- Whether VAT is added on top
- Whether you get a written report with photos
