About our thermal roof survey in Blackheath
A thermal survey isn’t a quick fix for every roof problem. 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 do not. If a finding cannot be confirmed, the report suggests a next step. Common reasons to book are wet areas near outlets and upstands and damp around chimneys and parapets, across flat roofs, loft conversions and insulated roof spaces.
In a small place like Blackheath, open ground can mean strong wind. A small drone cannot fly safely in strong wind or a downpour, and thermal imaging works best with little wind. The visit is planned around the forecast, along with the journey and access. A change in the forecast can mean moving the visit to another day.
After the visit, you get a written report with photographs, sent by email. It explains the condition of the roof, the defects we found and what we recommend.

What we look for on each type of roof
Pitched slate and tile roofs
Inside the loft space, thermal images can help with damp around stacks, valleys and roof windows. Findings are checked with moisture readings.
Felt and asphalt flat roofs
Felt and asphalt sit tight to the layers below, which frequently helps the camera pick up differences. We confirm any patterns with moisture readings.
Questions from Blackheath
Do you carry out roof surveys in Blackheath?
Yes, Blackheath is within the area we cover. We work right across London and South East England. You can call 07833 053749 or drop us an email with the address and a few details.
Is Blackheath within the area you cover?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
Can you tell me if my roof has asbestos?
No. We do not carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are frequently shared, so the building owner or managing agent needs to agree access. We inspect only the parts we’re allowed to reach.
How experienced are you?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys across London and South East England.
Can you use a thermal camera on a sloping roof?
It can be useful, though pitched roofs are normally harder to read. Slates and tiles over a ventilated space can mask what’s below, so we combine it with an inspection from the loft where there’s safe access.
Does someone need to be in?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you as you book.
Thermal roof surveys in Blackheath: local notes
If your survey includes the drone, we check the Drone Safety Map for restrictions before flying. Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Horsham stone slab roofs survive on some old buildings in Surrey. Many roofs like these cannot be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place.
Take a building like Chilworth CofE (Aided) Infant School: big roofs are where close-up aerial shots and thermal images show the most at once. Historic houses such as Chilworth Manor, about 1.1 miles north, show how far back building around Blackheath goes. For older roofs nearby, a look from the air or with a thermal camera is a hands-off way to check condition. If you live in an older home near Church of St Martin, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.

How the survey works
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, take photographs as we go and make notes for the report. It typically takes between one and two hours for most homes, plus time to check any thermal findings with moisture readings. In a small place like Blackheath, access is usually the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- 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.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Before we arrive
- Have keys ready for side gates, garages or roof access doors
- Leave a clear route to the loft
- If it isn’t your property yet, arrange access through the agent
How to book
A quick phone call is typically the easiest start: phone 07833 053749 or send us an email, and we will ask about the building and what you need. You will have a price before anything is arranged.
Related advice
Before and after the survey
Nothing here needs a ladder. Our suggestions:
- Note where damp appears and after what weather
- Keep dated photos of any marks on ceilings
- Check from the ground or a window, never by climbing
- Clear leaves from outlets and gutters each autumn
Where a pattern cannot be confirmed, the report says what could help, such as electronic leak detection or opening up a small area.
Check that loft insulation is laid evenly and hasn’t been pushed aside. Gaps often appear after work in the loft.
What you can safely check yourself
It’s useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking.
A DIY look is useful, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
