What a thermal roof survey looks like in West Dulwich
If your survey includes the drone, we check the Drone Safety Map for restrictions before flying. Historic houses such as Kingswood House, about 0.2 miles south, show how far back building in the area around West Dulwich goes. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years.
For a London address like West Dulwich, it’s useful to know about controlled parking before the day. Take a building like Dulwich Wood Primary School: thermal images can show where wet insulation sits under a big flat roof. If you run a business near Lewisham Shopping Centre, large commercial roofs are often easiest to see from the air or with a thermal camera.

How a thermal roof survey works in West Dulwich
A thermal camera can help when the cause of damp is not obvious. Leaks frequently run along a roof before they appear on a ceiling, and the camera can show patterns that help us follow it. The images are used alongside a visual inspection and moisture readings, so no conclusion rests on one method alone. We’re often asked to look into wet areas near outlets and upstands and cold areas below the roof, across ceilings below the roof, commercial roofs and loft conversions.
In London’s terraces and conversions, roofs are packed close together, so privacy and neighbours matter as much as the view. We take care to focus on the roof we’ve been asked to look at, in West Dulwich as anywhere. Tell us about the building and access when you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
After the visit, you get a written report with photos, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

What we look for on each type of roof
Single-ply and EPDM roofs
On big single-ply roofs, the camera helps show where to take readings. That makes the survey more focused.
Pitched slate and tile roofs
On pitched roofs, slates and tiles over a ventilated space can mask what’s happening underneath. We combine the images with an inspection from the loft where there’s safe access.

What affects the price in West Dulwich
To price your survey, we look at:
- Building height and the viewpoints available
- The roof’s overall size
- Extra roofs, like extensions, dormers or garages
- Whether you choose the Basic, Standard or Premium Survey
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. Size, height and access can affect the price too.
Getting in touch
There’s no need for technical words. It’s enough to tell us:
- Whether there is a loft hatch, a shared roof or tricky access
- Where any leaks, stains or damp patches show inside
- Your postcode, so we can check access and travel
- Pictures of the roof from a safe spot, if you have them
When you’re ready to go ahead, ring 07833 053749 or email us. From there it is a case of choosing a package, agreeing the price and fixing a day.
What this survey can’t tell you
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- Structural calculations, which need a structural engineer
- What’s inside walls or under coverings, without opening up
- Clear results when the conditions on the day are poor
Not sure which survey suits your roof? You can call 07833 053749 or email us and we’ll tell you before booking. What a survey covers and does not.
Roofs we survey in West Dulwich
- Commercial roofs
- Ceilings below the roof
- Loft conversions
- Flat roofs
- Insulated roof spaces
- Pitched roof slopes
Why get it checked now?
The longer moisture sits in a roof, the more it can affect timbers and finishes below. Surveying sooner gives you more choice about what to do. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. When the stain finally shows, the damage underneath is often older than it looks.

Checking the roof from the ground
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
What we do, step by step
We check the roof from outside and, where it’s relevant and there is safe access, from inside the roof space too. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit typically takes about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. In a London area like West Dulwich, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at everything that’s safely in view from ground level, windows, the loft and, where it’s safe, the roof itself.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- We check the roof from ground level, from windows and from the roof itself where it’s safe.
- Thermal images are taken to show differences in surface temperature.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- We write up the thermal images alongside ordinary photos and recommendations.
How to prepare
- Have any questions written down, so nothing gets missed
- If the roof is shared, arrange access with whoever manages the building
- Keep pets in another room

West Dulwich: your questions answered
Will parking be an issue for a roof survey in West Dulwich?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we will work around them.
Can you fly a drone over a roof in West Dulwich?
It depends on the exact address and the weather on the day. 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. Every London address is checked against them before a flight. Every flight is checked against the Drone Safety Map first, including zones around airports and prisons. The flight also waits for calm, dry weather.
What does the report include?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. Points are put in order of urgency where relevant.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Does thermal imaging detect leaks directly?
The camera does not see water itself. Because wet insulation holds heat for longer, it can show as a different temperature, but we check each finding with moisture readings.
What’s the best way to book?
It is easiest to ring 07833 053749 or send us an email. Give us the address and a few details about the roof, and we’ll take it from there. Surveys run on any day of the week.
Do you carry out surveys on Saturdays and Sundays?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you when you book.
