Thermal roof surveys for homes and businesses in Windlesham
Thermal imaging is a useful tool, but it has limits. It shows surface temperature, and things like sun, shade, reflections and wind all affect the readings. We back up the images with moisture readings and a careful look at the roof. The report is clear about what the images show and what they don’t. If a finding cannot be confirmed, the report suggests a next step. We survey loft conversions, insulated roof spaces and flat roofs, and common reasons people get in touch are patches of heat loss across the roof and wet areas near outlets and upstands.
In smaller places like Windlesham, many homes are bungalows and houses with roofs you can partly see from ground level. Chimney tops, valleys and rear slopes are where close-up or thermal images help most. The forecast decides the day. Even so, a close-up image often shows wear on ridges and flashings that a view from the ground misses.
Findings are set out part by part, from the main slopes down to the gutters and outlets. It records what’s sound as well as what isn’t.

What this survey can’t tell you
Without opening up the roof, some things stay hidden, and that sets some limits:
- Whether the deck or roof structure is strong enough
- Readings unaffected by sun, shade or reflections
- Insulation values or heat loss calculations

Roof by roof
Loft insulation
Heat loss shows most clearly when it’s warm inside and colder outside. Our report notes how the conditions affected the images.
Parapets, valleys and junctions
Water often gets in where roofs meet walls, parapets or valley gutters. The camera can help show damp around these junctions.
Your questions about thermal roof surveys in Windlesham
Does a conservation area affect roof work in Windlesham?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is Windlesham within the area you cover?
Yes. Windlesham is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and South East England. Just mention lanes, gates or anything else about the route as you book.
Can a thermal camera see water?
No, not on its own. It shows surface temperature, and wet areas can show up because they hold heat differently. We confirm what it suggests with moisture readings.
How do I book a survey in Windlesham?
The quickest way is to phone 07833 053749 or use the contact form. Give us the address and a few details about the roof. Surveys run on weekdays, Saturdays and Sundays.
Can a thermal survey trace a roof leak?
It often helps show where to look. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. It is used alongside a close inspection and moisture readings, as the camera alone cannot prove a leak.
Do you use drones?
Yes, where it’s applicable. Flights depend on the weather on the day and airspace rules. We’re a CAA-registered drone operator.
Are you insured?
Our cover is professional indemnity plus public liability.
What we do, step by step
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Being in a smaller place like Windlesham does not change how the visit works: outside, inside and from any safe vantage point, in that order. It helps to show us anything you’ve already noticed.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- We back up the thermal patterns with moisture readings.
- The Premium report reaches you the same day, and we go through it with you in person.
Before the survey
- Jot down any questions you want answered
- Gather any invoices or paperwork from past roof work
- Mention any parking restrictions on your street
How to book
Thermal roof survey starts from £400, including VAT. The exact figure depends on the roof and the package, so phone 07833 053749 or drop us an email with the details.
Advice
Tips from our surveys
There is plenty you can do without going near the roof. What helps most:
- Make sure the loft can be reached safely
- Keep dated photos of any marks on ceilings
- Talk to us about the weather when booking
- Use the report as a baseline for later checks
The report explains the conditions on the day and how they affected the images. That way you know how much weight to give each finding.
Check loft insulation covers the whole area and hasn’t been disturbed. Insulation is often moved when people work in the roof space.
Thermal roof surveys in Windlesham: local notes
There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so the council is the place to ask. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail.
Anyone responsible for a site like Windlesham Village Infant School will know that big roofs are where photos from the air and thermal images show the most at once. Take an older house close to Church of St John the Baptist: thin or patchy insulation under an old roof often shows up clearly on a thermal image.

Why it is worth a survey now in Windlesham
For buyers, a thermal survey adds detail that a visual inspection can’t give. Finding hidden moisture before exchange gives you facts to raise with the seller. Around Windlesham, a leak in an older house can soak into timbers and plaster, and that’s a much bigger job than the original defect.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. The roof’s size, height and access matter as well.

Should I look at the roof myself first?
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
