Thermal imaging roof survey in Sundridge, Greater London
Find out what’s going on with the roof before you decide what to do next. We carry out thermal roof surveys in Sundridge.
- Stains that keep coming back
- Damp around roof outlets and upstands
- Cold spots on ceilings under the roof
Why it’s worth a survey now in Sundridge
Heat lost through a roof costs money every winter. Thermal images can show where insulation is missing or has slipped, so improvements can go where they’re needed. In Sundridge, as across London, an overflowing gutter soaks the wall below, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.
Thermal roof survey starts from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included, and we’ll tell you which fits.
Why us?
- Every finding written up with photos
- An independent view of the roof

Thermal roof surveys for homes and businesses in Sundridge
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera doesn’t see water itself, so findings are checked with moisture readings. Thermal imaging is included in our Premium Survey, from £400. The report also notes the conditions on the day, since they affect what the camera can show. Common reasons to book are damp around chimneys and parapets and areas losing heat at the eaves and junctions, on pitched roof slopes, flat roofs and loft conversions.
London’s roofs are often hard to see from the street: valley gutters behind parapets, dormers and flat-roofed rear additions. Drone photos and thermal images can show parts of a roof that are hard to reach safely. Weather on the day decides whether it goes ahead, in Sundridge as anywhere. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
The report works through the roof section by section, from the coverings down to the gutters, with a note and a photo for each point. It records what’s sound as well as what isn’t.

What a thermal roof survey looks like in Sundridge
Bromley Palace, about 0.9 miles south, is one of the historic houses in the wider area around Sundridge. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Steep or complicated roofs are frequently hard to see from the ground, which is where photos from the air and thermal images help.
If you look after a building such as St Joseph's Catholic Primary School, a drone or thermal camera can show a large roof in a single visit. For an older house near a landmark such as St Andrew, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Sundridge is about 1 mile north-east of Bromley, in Greater London. Sundridge is one of many places we visit across Greater London. Sundridge is one of the towns and villages in Greater London where we work. We also survey roofs in London.
All of BR1, BR7 and BR2 is covered for thermal roof surveys, from the main roads to the quietest streets. Whether your property is on Hawes Road, North Road and Croft Road or a nearby road, we can survey it. Other places close to Sundridge include Plaistow (1 mile west), Grove Park (1 mile north), Downham (1 mile north-west), Chinbrook (1 mile north) and Elmstead (1 mile east). Within a short drive, we also cover London (8 miles north-west), City of Westminster (10 miles north-west), Marylebone (10 miles north-west), Kensington (11 miles north-west), St Pancras (10 miles north-west) and Shoreditch (9 miles north-west).
What’s near Sundridge
Typical jobs here are in homes near Elmstead Wood, Holy Trinity College Bromley and Haberdashers' Aske's Knights Academy, among other places. Sundridge has its own railway station: Sundridge Park station. Well-known places in the area include Bromley Hospital (1.4 miles south) and Greenwich Castle (4.4 miles north). Not far away are Summer Hill and Downham Woodland Walk.
The survey, step by step
It’s useful 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. Most visits take roughly 1–2 hours for most houses, while a commercial roof takes nearer three to four hours. In Sundridge, as in much of London, plenty of properties are flats or terraces without side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when you book.
- 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.
- A full inspection and thermal imaging are carried out together.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Getting ready for the survey
- Move anything stored under the loft hatch
- Show us where any leaks or stains appear
- Keep pets inside or away from the areas we’re looking at

Advice
What else we do in Sundridge
Tips that help
Most of what helps is simple and safe from the ground. Our suggestions:
- File the images with your roof records
- Keep dated photos of any marks on ceilings
- Check outlets after heavy rain
- Check from ground level or a window, never by climbing
After the visit, we put the thermal images, photos and moisture readings into one report. Each image is explained in plain words, alongside what we recommend. Premium reports are sent the same day.
Have small defects in the covering fixed early. Once water gets under a membrane, it can travel far before it appears inside.
When to book a survey in Sundridge
Building owners and managing agents use thermal surveys to plan work on larger flat roofs. Patterns can point to wet areas and show which parts look sound, so we know where to take moisture readings.
A survey makes sense if you’ve noticed:
- Leaks far from where the stain appears
- Heat escaping through the roof
- Damp patches with no obvious cause
- Moisture around outlets and upstands
Controlled parking zones are common in London, so mention any permit rules for Sundridge.
Before booking any roof surveyor
- What’s outside the scope of the survey
- Their insurance cover
- Whether the loft is part of the inspection
- When you’ll get the report
Honest limits
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Insulation values or heat loss calculations
- Reliable images in rain, strong wind or on a wet roof surface
- Seeing water directly, as the camera shows temperature, not moisture

Sundridge: your questions answered
Is my home in Sundridge listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Is parking a problem for a survey in Sundridge?
It rarely stops a survey, but it’s worth planning. Tell us what parking is available nearby, and the visit is planned around it.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
Does thermal imaging work on slate and tile 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.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photographs. It also says if any part of the roof couldn’t be seen safely.
Will you photograph what you find?
Yes. Photos are taken throughout the survey, and they go into the written report.
I live in a flat. Can you survey the roof?
Yes, if the freeholder or managing agent agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
Roof by roof
Single-ply and EPDM roofs
Because these membranes are thin, patterns from below frequently show. Shiny surfaces can reflect heat, so we take care reading the images.
Parapets, valleys and junctions
Problems where roof slopes and walls meet are often hidden. A careful visual inspection goes alongside the images.
