Questions from Merle Common
How do I find out if my home in Merle Common is listed?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you carry out roof surveys in Merle Common?
Yes, Merle Common is within the area we cover. We survey roofs across London and South East England. You can call 07833 053749 or use the contact form with the address and some details, and we will talk through which survey suits.
Is thermal imaging good for finding leaks?
It frequently helps show where to look. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. We combine it with a visual inspection and moisture readings because the camera cannot confirm water on its own.
Do you climb onto every roof?
Only if it’s safe. We inspect everything that’s safely in view: from the ground, from windows, from inside the loft space, from the roof where it’s safe and by drone where applicable. Anything we can’t see is noted in the report.
Does thermal imaging detect leaks directly?
No, not on its own. It shows temperature, and wet materials often behave differently from dry ones. We confirm what it suggests with moisture readings.
Do you carry out surveys on Saturdays and Sundays?
We survey seven days a week: weekdays, Saturdays and Sundays. Let us know which days suit you when you book.
What do I do with the report?
You’ll get the report by email, with photos and clear recommendations. With Standard there is a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Thermal roof survey in Merle Common
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. It is important to know that the camera shows temperature, not water, so we check what it shows with moisture readings. It comes as part of our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. We’re often asked to look into areas losing heat at the eaves and junctions and damp around chimneys and parapets, on loft conversions, commercial roofs and ceilings below the roof.
In a small place like Merle Common, open ground can mean strong wind. High wind or heavy rain stops a small drone flying, and calm conditions also suit thermal imaging best. We plan the journey, access and timing around the weather. A change in the forecast can mean moving the visit to another day.
The written findings come by email, ready to forward to whoever needs them. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

What a thermal roof survey looks like in Merle Common
Historic houses such as Chartwell, about 3.3 miles north-east, show how far back building in the area around Merle Common goes. 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, and a listed home or one in a conservation area may need consent for changes of material. If your survey includes the drone, the flight is checked against the Drone Safety Map first.
Anyone responsible for a site like Holland Junior School will know that big roofs are where photos from the air and thermal images show the most at once.

What affects the price in Merle Common
All our prices include VAT. What changes the price is:
- Any need for thermal images or a drone flight
- Features like valleys, chimneys, dormers and parapets
- The package you choose: Basic, Standard or Premium
- Building height and the viewpoints available
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Our price is from £400, including VAT.
What we need to know
Here’s what helps us most when you contact us:
- Anything about access we should know
- Where the property is, with the postcode
- Pictures of the roof from a safe spot, if you have them
- The type of building and roof, such as pitched or flat
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, phone 07833 053749 or send us an email.
Before and after the survey
These tips come from what we see on roofs every week:
- Check from the ground or a window, never by climbing
- Move stored items away from the loft hatch
- Talk to us about the weather when booking
- Keep outlets and gutters clear to stop water sitting
If you’re buying, the report gives you specific points to raise with the seller or agent. What you do with it is up to you, whether you ask for work before completion or discuss the price.
Clear outlets and gutters regularly, so water does not sit on the roof. Less standing water means less chance of it getting under the covering.
How the survey works
Photographs are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. Most surveys take an hour or two on an ordinary house, or half a day or so for a commercial building. Somewhere as small as Merle Common, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We go through the roof, the problem and the weather expected on the day.
- We look over the roof from wherever it’s 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.
Preparing for the visit
- Unlock side gates and any roof access doors
- Keep pets inside or away from the areas we are looking at
- Move anything stored under the loft hatch

When you need someone else
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Proving moisture from the images alone
- Insulation values or heat loss calculations
- What’s inside walls or under coverings, without opening up
If in doubt, phone 07833 053749 or drop us an email and we will suggest the right survey. What a survey covers and does not.
What we check
- Insulated roof spaces
- Ceilings below the roof
- Loft conversions
- Flat roofs
- Commercial roofs
- Pitched roof slopes

DIY checks: what’s safe
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That’s where a survey comes in.
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
Rented homes, blocks and businesses
Surveys can also be booked by buyers’ agents acting for a client. Reports are emailed, so they’re easy to pass on, photos included.
Where a roof is shared: we need access agreed with the building owner or managing agent. Mention it when you contact us and we’ll plan the visit with that in mind.
