Thermal roof surveys for homes and businesses in Stanmore
A thermal camera can help when the cause of damp isn’t obvious. 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. We survey commercial roofs, ceilings below the roof and insulated roof spaces, and the problems we are asked to look at most are damp patches with no obvious cause and leaks far from where the stain appears.
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. Tell us about the building and access when you book. The extra view helps most on steep slopes, tall stacks and rear additions.
We keep jargon out of it: if work is needed, the report says so clearly, and where it can wait, that is said too.

Flying and imaging in Stanmore
If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying. The wider area around Stanmore has a long history of building, with Headstone Manor about 2.5 miles south-west. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
For a London address like Stanmore, it’s useful to know about controlled parking before the day. If you run a business near Broadwalk Centre, big, flat commercial roofs are where close-up aerial shots and thermal images help most. Take an older house close to Church of St John: thin or patchy insulation under an old roof often shows up clearly on a thermal image.

What affects the cost of thermal roof surveys
Prices always include VAT. What changes the price is:
- House, block, shop or office
- Extensions, dormers and garages with roofs of their own
- The size of the roof
- Height and safe access
Prices start from £400, including VAT. The final price depends on the size and height of the roof, access and the package you choose.
What to let us know when you get in touch
The more you tell us, the easier it is to price the survey. When you contact us, it is useful to mention:
- The reason for the survey, such as buying, a leak or storm damage
- Where the property is, with the postcode
- How the loft is reached, if there is one
- Pictures from the garden or a window, if you have them
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, phone 07833 053749 or email us.
When you need someone else
It is a careful look at the roof, not the whole story. Its limits include:
- A formal energy assessment
- Whether the deck or roof structure is strong enough
- What’s inside walls or under coverings, without opening up
Not sure which survey suits your roof? You can call 07833 053749 or drop us an email and we’ll tell you before you book. What a survey covers and doesn’t.

What else we do in Stanmore
Surveys for landlords and agents in Stanmore
Businesses and commercial landlords can book us too. Bigger roofs take more time.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
What happens on the day
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey normally takes roughly 1–2 hours for a house, with bigger or more complicated roofs taking longer. In Stanmore, as in much of London, lots of properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when you book.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We carry out a visual inspection of the roof from wherever it can safely be seen.
- Thermal images are taken to show differences in surface temperature.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- You get a report with thermal images, photos and our recommendations.
How to prepare
- Check the loft hatch can be reached
- If the roof is shared, arrange access with whoever manages the building
- Let us know about any leaks, stains or damp patches you know of

Tips from our surveys
These tips come from what we see on roofs every week, before and after a survey:
- Clear leaves from outlets and gutters each autumn
- Move stored items away from the loft hatch
- Do not climb onto the roof to look for leaks yourself
- Heat the home normally on the days before
The report explains the conditions on the day and how they affected the images. It helps you judge how firm each finding is.
Clear outlets and gutters regularly, so water doesn’t sit on the roof. The less water sits, the less can find its way beneath.
What we look for on each type of roof
Pitched slate and tile roofs
Slate and tile roofs are often harder to read with a thermal camera, because of the air space beneath. We combine the images with an inspection from the loft where there’s safe access.
Single-ply and EPDM roofs
Thin membranes can show patterns from the layers beneath. Shiny surfaces can reflect heat, so we take care reading the images.
Stanmore questions
Does a conservation area affect roof work in Stanmore?
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.
Will parking be an issue for a roof survey in Stanmore?
Usually it is manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
Will the camera show exactly where the water is?
Thermal imaging shows temperature rather than water. Wet insulation holds heat longer than dry, so it can stand out, but we check each finding with moisture readings.
Can you survey a shared roof?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from the freeholder or managing agent. We inspect only the parts we are allowed to reach.
How long does the survey take?
Expect it to take roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. The written report follows by email.
How experienced are you?
Over 5,000 surveys so far, across 20+ years of surveying roofs, with 98% customer satisfaction.
Which survey includes thermal imaging?
Our Premium Survey, from £400, includes thermal imaging. An in-person consultation and a follow-up 12 months later are included too. For bigger commercial roofs, we quote on size.
