Cranham Thermal Roof Survey
Thermal roof surveys in Cranham and the rest of Greater London. We survey on weekdays and at weekends.
- Possible trapped moisture under a flat roof covering
- Wet areas near outlets and upstands
- Ceilings that feel colder in places
Thermal roof surveys for homes and businesses in Cranham
Your report sets out the thermal images alongside ordinary photographs, so it’s easy to see which part of the roof each one shows. Each one comes with an explanation, the moisture readings and our recommendation. With a Premium Survey, the report reaches you the same day. You can talk the findings through with us at the in-person consultation. A follow-up 12 months later is included too. We survey commercial roofs, ceilings below the roof and flat roofs, and people most often book us about gaps in loft insulation and cold spots on ceilings under the roof.
London airspace is busy and tightly controlled: there are flight restriction zones around Heathrow, London City and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Before a drone goes up in Cranham, the address is checked against all of them, and permission is never taken for granted.
We write the report in plain English, so it makes sense without any roofing background. Photographs show what each point refers to, with the urgent items made clear.

What affects the price in Cranham
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
- Features like valleys, chimneys, dormers and parapets
- The roof’s overall size
- Whether thermal imaging or a drone is needed
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Thermal roof survey starts from £400, including VAT.
What we need to know
A little information up front helps. Please include:
- Where the property is, with the postcode
- Any marks or damp showing indoors
- What kind of property and roof it is
- Any deadline, such as an exchange date
To arrange a survey, call 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You will know the price before anything is booked.
Tips that help
Here are a few things we’d tell any owner:
- Check the loft can be reached safely
- Use the report as a baseline for later checks
- Do not switch the heating off ahead of the visit
- Remember the conditions on the day affect the results
Once we’ve been, the thermal images, photos and readings go into a single report. Each image is explained in plain words, alongside what we recommend. With a Premium Survey, you get the report the same day.
Keep outlets and gutters clear so water drains off the roof quickly. The less water sits, the less can find its way beneath.
Surveys for landlords and agents in Cranham
Shared roofs need a little more planning: we need access agreed with the building owner or managing agent. Let us know about it when you book and we will plan the visit with that in mind.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
When you need someone else
We only report whatever is safely visible on the day, so there are some things a survey cannot cover:
- Confirming water without moisture readings
- Reliable images in rain, strong wind or on a wet roof surface
- Structural calculations, which need a structural engineer
Not sure which survey suits your roof? You can call 07833 053749 or drop us an email and we’ll tell you. What a survey covers and does not.
What this survey covers
- Loft conversions
- Insulated roof spaces
- Commercial roofs

Cranham questions
How do I find out if my home in Cranham is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Can you fly a drone over a roof in Cranham?
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. Before any flight, we check the Drone Safety Map for airspace restrictions, including zones around airports and prisons. Strong wind or a downpour also stops a small drone flying.
What happens next?
The report arrives by email. With Standard there’s a follow-up consultation; with Premium, an in-person consultation.
Which days do you carry out surveys?
Surveys run on weekdays, Saturdays and Sundays. To find a day that suits you, call 07833 053749 or use the contact form.
Will thermal imaging find my leak?
It’s a useful tool for tracing leaks, but not the only one. What it shows depends on the weather and the roof. Where it cannot be pinned down, the report suggests a next step, such as electronic leak detection.
What’s in the survey report?
A written report with photos, explaining the condition of the roof, any defects and our recommendations, by urgency where it matters. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where it applies and structural analysis.
Is this an asbestos survey?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
What we do, step by step
Photos are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. A typical visit takes about 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. From the street, a London terrace normally shows only its front slope or parapet, so a visit in Cranham moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- 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.
- The Premium report reaches you the same day, and we go through it with you in person.
Getting ready for the survey
- Check the loft hatch can be reached
- Find any records of previous roof work
- Unlock side gates and any roof access doors
Booking a survey
If you’re buying, it helps to book soon after your offer is accepted, so there is time to use the report before exchange. Otherwise, simply ring 07833 053749 or email us whenever suits you.

Thermal roof surveys around Cranham
Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Many roofs like these cannot be judged properly from the pavement, and that is where a view from above or a thermal image earns its place. Historic houses such as Hare Hall, about 3 miles north-west, show how far back building in the area around Cranham goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
If you run a business near The Mercury Mall, big, flat commercial roofs are where close-up aerial shots and thermal images help most. For a London address like Cranham, it helps to know about controlled parking before the day, along with any off-street space.
Cranham is about 2 miles east of Hornchurch, in Greater London. We survey roofs in Cranham and the surrounding area as part of our work across London and the South East. Our Greater London coverage includes Cranham. We also survey roofs in Chelmsford.

Do you need a thermal roof survey in Cranham?
People often book a thermal survey when a damp patch has no obvious cause. A leak may start well away from where the stain appears. Temperature patterns can help narrow down where to look.
Typical things we are asked to look at include:
- Damp around chimneys and parapets
- Areas losing heat at the eaves and junctions
- Cold areas below the roof
- Thin or uneven insulation in the roof
Anyone responsible for a site like Hall Mead School will know that a view from above covers a wide roof far faster than walking it.
