Thermal roof survey in Waterdale: what you get
A thermal survey isn’t a quick fix for every roof problem. Sun, shade, reflective surfaces and wind can all change what the camera shows. 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. Where something cannot be confirmed, we say what would help next. Common reasons to book are damp around chimneys and parapets and moisture around outlets and upstands, on flat roofs, loft conversions and pitched roof slopes.
Older buildings in small places like Waterdale may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, so it’s a gentle way to see the condition of an old roof, before anyone decides what work it needs. Check with the council before planning any work on a listed building or one in a conservation area.
The report records the roof as we found it on the day. That makes it useful now and a handy reference later, for example when you want to check whether anything has changed.

Roof by roof
Felt and asphalt flat roofs
On felt and asphalt flat roofs, wet insulation can show as a temperature difference across the surface. We check those patches with moisture readings.
GRP fibreglass roofs
GRP roofs are laid over timber boards, so trapped moisture can affect the deck. The camera can help show where to look.
FAQs for Waterdale
Is Waterdale in the area you cover?
Yes. We work right across London and South East England, and Waterdale is part of that. Just phone 07833 053749 or drop us an email and let us know about the property, and we’ll talk through which survey suits.
Will you come out to Waterdale?
Yes, Waterdale is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Will the camera show exactly where the water is?
Thermal imaging shows temperature rather than water. Because wet insulation holds heat for longer, it can show as a different temperature, but we check each finding with moisture readings.
Is thermal imaging useful on pitched roofs?
It can show heat loss and some damp, but it has more limits there. We explain what the images can and cannot tell you, and back them up with a visual inspection and moisture readings.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
Are you structural engineers?
No. We note visible signs like sagging or deflection, but we are not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
Will the survey show heat loss through my roof?
It can show temperature patterns that point to missing or thin insulation. It shows most clearly when it’s warm inside and cold outside. Where we can reach the loft safely, we check there too.

Common roof problems in Waterdale
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Gaps in loft insulation and poorly insulated roof areas can show up on the camera, particularly when it is warm inside and cold outside.
A survey can pick up problems like:
- Damp around roof outlets and upstands
- Wet insulation beneath the membrane
- Damp around chimneys and parapets
- Patches of heat loss across the roof
For an older house near a landmark like Church of All Saints, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Choosing a roof surveyor
- Is VAT included in the price?
- How long they’ve been surveying roofs
- What’s outside the scope of the survey
- What happens after the report arrives
Can I check my roof myself?
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where applicable.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
What we do, step by step
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit typically takes between one and two hours for most houses, rising to roughly 3–4 hours on a commercial building. Cottages and farmhouses around Waterdale often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- 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.
- 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.
Getting ready for the survey
- Mention any parking restrictions on your street
- Have keys ready for side gates, garages or roof access doors
- Jot down any questions you want answered
Arrange a survey
Booking is simple: just ring 07833 053749 or drop us an email, tell us about the property and we will explain which survey suits. The price is agreed up front.

For landlords and managing agents
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we’ll plan the visit with that in mind.
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work.
Drones, thermal imaging and Waterdale roofs
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. About 0.5 miles south-west lies High Elms Manor, a reminder of how long the area around Waterdale has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
If you look after a building such as Parmiter's School, thermal images can show where wet insulation sits under a big flat roof. If you look after a shop, office or commercial unit, for example near Charter Place, large commercial roofs are often easiest to see by drone or thermal camera.
