Hamsey Green Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof in Hamsey Green, with drones and thermal imaging where they help. Call or email for a price.
- Gaps in loft insulation
- Damp around chimneys and parapets
- Wet insulation beneath the membrane
What affects the cost of thermal roof surveys
Several things affect the price of a survey:
- The roof’s overall size
- Whether it is a home or a commercial building
- Basic, Standard or Premium
- Features like valleys, chimneys, dormers and parapets
Thermal roof survey starts from £400, including VAT. What you pay depends on how big and how high the roof is, how it can be seen safely and the package you choose.
Helping us price your survey
A little information up front helps. Please include:
- When you need the report by
- The property’s address and postcode
- Anything about access we should know
- Any stains, drips or damp patches you’ve seen indoors
Every survey is priced before it is booked, so you know the cost up front. Prices start from £400, including VAT. To book, ring 07833 053749 or email us.
Thermal roof surveys for homes and businesses in Hamsey Green
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. The camera does not see water itself, 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. Common reasons to book are missing or slipped insulation and leaks that are hard to trace, on ceilings below the roof, insulated roof spaces and flat roofs.
Villages like Hamsey Green frequently stand in open country, where wind can be strong. 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.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

What happens on the day
Every roof is different, but as a rough guide the survey takes about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. You’re welcome to ask questions while we’re there. In a small place like Hamsey Green, access is normally the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Preparing for the visit
- Make a note of anything you’d like us to look at
- Agree roof access with the managing agent if it is shared
- Tell us about parking before the day
Getting a price
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. Otherwise, simply ring 07833 053749 or email us whenever suits you.

Rented homes, blocks and businesses
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. Access is agreed with the tenant beforehand.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the survey around it.
Thermal roof surveys in Hamsey Green: local notes
If the drone is used for your survey, the flight is checked against the Drone Safety Map first. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. Many roofs like these cannot be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place.
With Addington Palace about 2.8 miles north, the area around Hamsey Green has a long history. Older roofs nearby can be steep and hard to see from ground level, and a survey from above or with a thermal imager does not touch the roof itself. For site and facilities teams at buildings such as Hamsey Green Primary, thermal images can show where wet insulation sits under a big flat roof. If yours is one of the older homes in the streets near St Antony, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view from the air or with a thermal camera helps.

Should I look at the roof myself first?
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when booking.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Practical tips
You do not need to be a roofer to help. Here’s what helps most:
- Clear leaves from outlets and gutters each autumn
- Do not climb onto the roof to look for leaks yourself
- Tell us where and when you’ve seen damp or stains
- Use the report as a baseline for later checks
Many people send the report to roofers, who can then quote for the areas shown. Each thermal image is matched to a normal photo, so the areas are easy to locate.
Have small defects in the covering fixed early. Once water gets under a membrane, it can travel far before it appears inside.

Hamsey Green questions
Do you cover Hamsey Green?
Yes. We survey roofs across London and the South East, and Hamsey Green is part of that. Just call 07833 053749 or use the contact form and let us know about the property, and we will talk through which survey suits.
Does a conservation area affect roof work in Hamsey Green?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
How soon will I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
How long is the visit?
It normally takes roughly 1–2 hours at a typical home, and about three to four hours for a commercial roof. The written report follows by email, on the timescale of your package.
Is thermal imaging good for finding leaks?
Thermal imaging can help, alongside other checks. What it shows depends on the weather and the roof. If the source cannot be confirmed, we will say what could help next, such as electronic leak detection.
What’s the best way to book?
It’s easiest to ring 07833 053749 or use the contact form. Let us know the address and a little about the roof. Surveys run on any day of the week.
Is this a RICS survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
What we look for on each type of roof
Felt and asphalt flat roofs
Felt and asphalt sit tight to the layers below, which often helps the camera pick up differences. Any patterns are checked with moisture readings.
Loft insulation
The difference is clearest when the home is heated and it is cold out. Our report notes how the conditions affected the images.
