Perry Vale Thermal Roof Survey
Thermal roof surveys in Perry Vale, backed by more than 20 years’ experience. Every survey ends with a written report and photographs.
- Leaks that are hard to trace
- Possible trapped moisture under a flat roof covering
- Thin or uneven insulation in the roof
DIY checks: what’s safe
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Thermal roof surveys for homes and businesses in Perry Vale
Thermal imaging is useful when a damp patch has no clear cause. Leaks often 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. If you’ve noticed stains that keep coming back and ceilings that feel colder in places, 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. Images are taken to show the roof we’re surveying, with care for neighbours’ privacy. Tell us about the building and access when booking. The extra view helps most on steep slopes, tall stacks and rear additions.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Thermal roof surveys around Perry Vale
Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. Where the drone is part of the survey, the flight is checked against the Drone Safety Map first.
For an older house near a landmark such as Christ Church, thin or patchy insulation under an old roof often shows up clearly on a thermal image. Take a building like Perrymount Primary School: thermal images can show where wet insulation sits under a big flat roof.

What we are asked to look at in Perry Vale
Once a leak has been fixed, people often ask whether the roof is still wet. Thermal images and moisture readings can suggest whether moisture is still trapped, given suitable conditions on the day.
Look out for signs like these:
- Stains that keep coming back
- Patches of heat loss across the roof
- Water getting in at parapets and stacks
- Possible trapped moisture under a flat roof covering
If you look after a shop, office or commercial unit, for instance near Lewisham Shopping Centre, thermal images can show trapped moisture across a wide commercial roof.
Choosing a roof surveyor
- Their insurance cover
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Their report turnaround times
- Whether the loft is part of the inspection
The survey, step by step
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will get on with the inspection. The survey itself takes between one and two hours at most homes; commercial roofs usually need 3–4 hours. London terraces rarely offer a view of the whole roof from one spot, so a visit in Perry Vale moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- 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.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
Before we arrive
- For flats, make sure roof access has been agreed
- Have any questions written down, so nothing gets missed
- Tell us about parking before the day
Arrange a survey
Our price is from £400, including VAT. What you pay depends on the roof’s size, access and the package, so call 07833 053749 or send us an email with the details.
Advice
Questions from Perry Vale
Is drone flying allowed in Perry Vale?
It depends on the exact address and the weather on the day. Across London there are restriction zones around Heathrow, London City and London Heliport, plus 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. Strong wind or heavy rain also stops a small drone flying, though the rest of the survey goes ahead either way.
How do I find out if my home in Perry Vale is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Will you walk on the roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the loft space and a drone where applicable.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email, ready to forward.
Will the survey show heat loss through my roof?
Thermal images can suggest where heat is escaping and where insulation may be missing. We do not give energy ratings or heat loss calculations, but the images show where improvements may help.
Will you photograph what you find?
Yes, every report has them. Each finding is shown in a picture where possible, which makes the report easy to follow.
What happens after the survey?
You will get the report by email, with photos and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
