About our thermal roof survey in St Mary Cray
Thermal imaging is a useful tool, but it has limits. Sun, shade, reflective surfaces and wind can all change what the camera shows. We back up the images with moisture readings and a careful look at the roof. Our report says plainly what the camera picked up and how sure we can be. If a finding can’t be confirmed, the report suggests a next step. If you’ve noticed gaps in loft insulation and leaks far from where the stain appears, a survey will tell you what’s going on, whatever the roof.
London roofs sit shoulder to shoulder in terraces and blocks, so privacy and neighbours matter as much as the view. We take care to focus on the roof we have been asked to look at. Mention access, height and anything unusual about the building when you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

Practical tips
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Keep dated photos of any marks on ceilings
- Keep outlets and gutters clear to stop water sitting
- Leave the roof to people with safe access
- Keep the heating on as usual before a heat loss survey
The report explains the conditions on the day and how they affected the images. That way you know how much weight to give each finding.
Watch for new damp patches on ceilings beneath the roof. Catching a leak early stops insulation getting soaked.
Flying and imaging in St Mary Cray
If your survey includes the drone, the flight is checked against the Drone Safety Map first. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help.
Controlled parking zones are common in London, so mention any permit rules for St Mary Cray, along with any off-street space. Bromley Palace lies about 3.8 miles west, so building around St Mary Cray goes back a long way. Photos from the air and thermal images let an old roof be checked without anyone disturbing it.

What affects the price in St Mary Cray
Not every roof costs the same to survey, for these reasons:
- The package you choose: Basic, Standard or Premium
- Commercial roofs and larger buildings
- Roof area
- Extensions, dormers and garages with roofs of their own
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. Our price is from £400, including VAT.
Getting in touch
To price your survey accurately, we will ask about:
- What made you get in touch
- How the loft is reached, if there is one
- Your timetable, such as an exchange date
- What kind of property and roof it is
A quick phone call is usually the easiest start: ring 07833 053749 or use the contact form, and we will ask about the building and what you need. You will have a price before anything is arranged.
How the survey works
Before we start, tell us why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit usually takes about one to two hours at a typical home, and longer for a large or complex roof. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- We go through the roof, the problem and the weather expected on the day.
- We look over the roof from wherever it is safe.
- We take thermal images of the roof and of the loft where we can reach it.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
Getting ready for the survey
- Tell us about parking before the day
- Make a note of anything you’d like us to look at
- Check we can get to the back of the property
Getting a price
Once you know what you need, ring 07833 053749 or use the contact form. From there it is a case of choosing a package, agreeing the price and fixing a day, weekday or weekend.

Honest limits
It is useful to know what a survey won’t do before booking:
- Confirming water without moisture readings
- A structural engineer’s assessment
- A formal energy assessment
If you’re not sure which survey you need, ring 07833 053749 or use the contact form and we will give you a straight answer. What a survey covers and doesn’t.
What this survey covers
- Commercial roofs
- Insulated roof spaces
- Ceilings below the roof
- Flat roofs
- Pitched roof slopes
- Loft conversions
Different roofs, different checks
Parapets, valleys and junctions
Parapet and valley gutters can overflow inside a building. Thermal images, checked with moisture readings, can help trace it.
Pitched slate and tile roofs
Inside the loft space, thermal images can help with damp around stacks, valleys and roof windows. Findings are checked with moisture readings.
Do you need a thermal roof survey in St Mary Cray?
Flat roofs that have leaked for a while can have wet insulation under the covering. Knowing how much of the roof is affected helps decide between a local repair and more. A thermal survey, checked with moisture readings, can give a much clearer picture.
We’re often asked to look at:
- Stains that keep coming back
- Wet insulation beneath the membrane
- Gaps in loft insulation
- Wet areas near outlets and upstands
If you look after a building like Poverest Primary School, a drone or thermal camera can show a large roof in a single visit.

St Mary Cray questions
Will parking be an issue for a roof survey in St Mary Cray?
It depends on the street. If St Mary Cray has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Does a conservation area affect roof work in St Mary Cray?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Does the report include photographs?
Yes. The report includes photographs of what we found, so you can see exactly what each finding refers to.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you will need a RICS survey as well.
Does the weather affect a thermal survey?
The weather makes a real difference. A sunny day beforehand, a dry surface and calm air all help. Rain and strong wind can make the images less clear, so we talk through the forecast when you book.
What does the report include?
It works through the roof part by part, in writing and with photos. The most urgent items are made clear.
