Thermal Roof Survey in Aperfield
Thermal imaging to find moisture and heat loss patterns in a roof in Aperfield, carried out by an experienced roof surveyor. Every survey comes with a written report and photographs.
- Cold areas below the roof
- Damp that repairs haven’t cured
- Wet areas near outlets and upstands
Different roofs, different checks
Pitched slate and tile roofs
From inside the loft, the camera can help with damp around chimneys, valleys and roof windows. We check any patterns with moisture readings.
Felt and asphalt flat roofs
Built-up felt and asphalt roofs can hide trapped water for a long time. Thermal imaging helps suggest where it is, when the conditions allow.
About our thermal roof survey in Aperfield
We present each thermal image next to a normal photo of the same area, making it clear where on the roof each pattern is. Each one comes with an explanation, the moisture readings and our recommendation. Premium reports are sent the same day. If you have questions, the in-person consultation gives you time to go through them. There’s a 12-month follow-up as well. If you’re worried about gaps in loft insulation and patches of heat loss across the roof, a survey will tell you what’s going on, whatever the roof.
In London’s terraces and conversions, roofs are packed close together, which makes care around neighbours part of the job. We take care to focus on the roof we have been asked to look at. Tell us about the building and access when you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

The survey, step by step
You do not need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll get on with the inspection. A typical survey takes between one and two hours for most homes, plus time to check any thermal findings with moisture readings. Surveys in Aperfield can be booked for any day of the week. London parking is frequently by permit or pay-and-display, so it is useful to know what’s near you. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there is safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
Getting ready for the survey
- Have any paperwork from past roof work to hand
- If you’re buying, check with the agent that we can get in
- Mention any parking restrictions on your street

Advice
Thermal roof surveys around Aperfield
Down House, about 1.7 miles north, is one of the historic houses in the wider area around Aperfield. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Aperfield is one of them, bay roofs, hips and later dormers each have their own details. Older coverings on steep or tall roofs are hard to judge from below, so close-up photos from the air and thermal images help.
If you live in an older home near St Mark's Church, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view by drone or thermal camera helps. Parking in Aperfield, as in most of London, takes a little planning: let us know about parking bays, permits or a driveway when you book.

Your questions about thermal roof surveys in Aperfield
Is parking a problem for a survey in Aperfield?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Can you fly a drone over a roof in Aperfield?
The answer turns on the exact location and the conditions on the day. Aperfield is about 2 miles from Biggin Hill Airport, so the Drone Safety Map is checked for restrictions around it before we fly. London’s airspace includes flight restriction zones around Heathrow, London City Airport and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Each address is checked against all of them before the drone goes up. Strong wind or heavy rain also stops a small drone flying, and the rest of the survey doesn’t depend on the drone.
Does the report include photographs?
Yes, plenty. Pictures sit next to the findings they show.
What conditions are best for thermal imaging?
Conditions on the day have a big effect on what the camera can show. A dry surface, little wind and a sunny spell beforehand help most. Our report notes the conditions and how they affected the findings.
How do I book a survey in Aperfield?
To arrange a survey, ring 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We’ll confirm the price and find a day that suits.
Do I need to be at home?
Not always. If we only need the outside, we can agree that in advance, but the loft and any rooms with damp need someone to let us in.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
Practical tips
Over many surveys, some simple habits stand out:
- Move stored items away from the loft hatch
- Take photos of stains as they appear, so we can compare
- Keep a record of when stains appear
- Check from the ground or a window, never by climbing
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.
Check that loft insulation is laid evenly and hasn’t been pushed aside. Insulation is often moved when people work in the roof space.
DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we look at the roof.
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.

What else we do in Aperfield
Leave it or get it looked at?
Wet insulation under a flat roof doesn’t dry out on its own while the covering stays on. In time, it stops insulating properly and can damage the deck. Finding the wet areas sooner keeps the work smaller. Many older London roofs have only old felt under the slates, or no underlay at all, so a slipped slate can soon mean water inside. Left unchecked, water soaks into timber and plaster and the damage spreads.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Our price is from £400, including VAT.
