- Structural calculations, which need a structural engineer
- Hidden layers that need to be opened up to check

Thermal roof survey in Carpenders Park: what you get
We present each thermal image next to a normal photo of the same area, making it clear where on the roof each pattern is. We explain what each pattern may mean, what the moisture readings found and what we recommend. With a Premium Survey, the report reaches you the same day. If you have questions, the in-person consultation gives you time to go through them. A follow-up 12 months later is included too. We’re frequently asked to look into missing or slipped insulation and cold areas below the roof, on pitched roof slopes, commercial roofs and ceilings below the roof.
London airspace is busy and tightly controlled: restriction zones surround Heathrow, London City Airport and London Heliport, and Hyde Park, the City of London and the Isle of Dogs have restricted areas of their own. Before a drone goes up in Carpenders Park, the address is checked against all of them, and permission is never taken for granted.
The report records the roof as we found it on the day. It’s useful straight away, and a good reference for later, for example when you want to check whether anything has changed.

Carpenders Park questions
Does a conservation area affect roof work in Carpenders Park?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Is parking a problem for a survey in Carpenders Park?
Parking in Carpenders Park, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access; we will agree the details when you book.
Do you work in Carpenders Park?
Yes. We survey roofs in Carpenders Park and the rest of Greater London, as part of our work across London and South East England. For a price, ring 07833 053749 or use the contact form.
Is thermal imaging useful on pitched roofs?
It can help, but the results are often less clear than on a flat roof. 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.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach.
What do I do with the report?
You will get the report by email, with photographs and clear recommendations. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
What happens on the day
Every roof is different; as a rough guide, the survey takes between one and two hours for most houses, and more on a big or complicated roof. If you have questions on the day, just ask. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, tell us as you book.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- The roof is inspected visually from safe viewpoints.
- A thermal camera records how the surface temperature varies across the roof.
- Any patterns of interest are checked with moisture readings where we can reach them.
- You get a report with thermal images, photographs and our recommendations.
How to prepare
- Have any questions written down, so nothing gets missed
- Gather any invoices or paperwork from past roof work
- Check the loft hatch can be reached
Arrange a survey
Once you know what you need, ring 07833 053749 or email us. From there it’s a case of choosing a package, agreeing the price and fixing a day, weekday or weekend.

How we price thermal roof surveys
What a survey costs depends on the time and equipment it needs. The main factors are:
- Whether you choose the Basic, Standard or Premium Survey
- Commercial roofs and larger buildings
- Chimneys, valleys, parapets and other details
- Roof area
Every price we give includes VAT, and the written report is part of the package. Our price is from £400, including VAT. Where your roof sits in the range depends on its size, height and access.
What to let us know when you contact us
Here’s what helps us most when you get in touch:
- The property’s address and postcode
- Where any leaks, stains or damp patches show inside
- What’s prompted the survey
- Photos of the roof, taken safely from ground level or a window
Our phone lines are open seven days a week. To book or ask a question, call 07833 053749 or send us an email.
What we’re asked to look at in Carpenders Park
Some defects simply cannot be seen with the eye. Wet insulation, gaps in insulation and heat loss are often invisible from outside. A thermal camera adds another way of finding them.
A survey makes sense if you’ve noticed:
- Heat escaping through the roof
- Water getting in at parapets and stacks
- Leaks that are hard to trace
- Wet areas near outlets and upstands
Carpenders Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway when booking, as a space near the door can’t be promised.
What to check before booking
- Are they insured for the work?
- Their track record with similar roofs
- How soon the report will arrive
- Whether the inside of the roof is included
Thermal roof surveys around Carpenders Park
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Carpenders Park is one of them, bay roofs, hips and later dormers each have their own details. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail.
If you run a business near Harlequin Centre, big, flat commercial roofs are where photos from the air and thermal images help most. For site and facilities teams at buildings such as St Meryl School, a drone or thermal camera can show a large roof in a single visit.

Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Look up at the roof after a storm, from the ground: 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.
Useful tips for Carpenders Park property owners
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Tips:
- Use the report as a baseline for later checks
- Clear a path to the loft hatch before we arrive
- Leave the roof to people with safe access
- Don’t switch the heating off ahead of the visit
Once we have been, the thermal images, photos and readings go into a single report. We explain what each image may mean, alongside what we recommend. Premium reports are sent the same day.
Watch for new damp patches on ceilings beneath the roof. Early action keeps insulation from staying wet.
