About our thermal roof survey in Blackthorn
A thermal survey can point to places where heat is escaping through the roof. Gaps in loft insulation and poorly insulated areas can stand out on the images. It works best when the building is heated and it is colder outside. Our report points out what the images suggest and where to look more closely. We do not give energy ratings or heat loss calculations. We are often asked to look into damp patches with no obvious cause and cold spots on ceilings under the roof, across flat roofs, commercial roofs and ceilings below the roof.
In a village or hamlet like Blackthorn, roofs can be steep, old and hard to see from the lane. Close-up drone photos and thermal images help show what cannot be reached safely. Both the forecast and the airspace are checked first, and the journey is planned beforehand. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
The report records the roof as we found it on the day. That makes it useful now and a handy reference later.

Before and after the survey
You don’t need to be a roofer to help. What helps most:
- Check outlets after heavy rain
- Keep a record of when stains appear
- Make sure the loft can be reached safely
- Take photos of stains as they appear, so we can compare
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.
Clear outlets and gutters regularly, so water doesn’t sit on the roof. Less standing water means less chance of it getting under the covering.
What happens on the day
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. Most surveys take about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Cottages and farmhouses around Blackthorn often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- The roof is inspected visually from safe viewpoints.
- We take thermal images of the roof to pick up temperature patterns.
- We check the patterns that stand out with moisture readings where there’s safe access.
- The report sets out the images, what they suggest and what we recommend.
How to prepare
- Jot down any questions you want answered
- Point out any leaks or damp patches
- Dig out any old roof reports or invoices
How to book
Booking is simple: just call 07833 053749 or send us an email and give us some details about the property and we’ll explain which survey suits. The price is agreed up front.
Advice
What a survey costs
To price your survey, we look at:
- The size of the roof

Prices start from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, inc. VAT, and we’ll tell you which fits.
Getting in touch
The more you tell us, the easier it is to price the survey. When you contact us, it helps to mention:
- What kind of property and roof it is
- The address and postcode of the property

Landlords, agents and block managers in Blackthorn
If you own several properties, you can book surveys for several addresses. To discuss a number of properties, phone 07833 053749 or drop us an email.
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time.
Checking the roof from the ground
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
Blackthorn: your questions answered
Do you carry out roof surveys in Blackthorn?
Yes. We survey roofs across London and the South East, and Blackthorn is part of that. Just ring 07833 053749 or send us an email and let us know about the property, and we’ll talk through which survey suits.
Will you come out to Blackthorn?
Yes, Blackthorn is covered. We work right across London and the South East, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Do you climb onto every roof?
Only when it is safe. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the roof space and a drone where it applies, and the report records anything we couldn’t see.
How does a thermal imaging roof survey work?
It records surface temperature across the roof. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, and we check them with moisture readings.
Will you photograph what you find?
Yes, every report has them. Each finding is shown in a picture where possible.
What conditions are best for thermal imaging?
Conditions on the day affect the results. It works best after a sunny day, with a dry roof surface and little wind. Rain, wind and heavy cloud can weaken the patterns, so we discuss the forecast when booking.
How do I arrange a thermal roof survey in Blackthorn?
Just phone 07833 053749 or use the contact form with the address. We’ll ask a few questions, confirm the price and agree a date, weekday or weekend.
Flying and imaging in Blackthorn
About 3.3 miles south lies Boarstall Tower, a reminder of how long the area around Blackthorn has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. If the drone is used for your survey, the flight is checked against the Drone Safety Map first.
The streets around a church such as Church of St Mary the Virgin are often among the oldest in a place, and if your house is among the older ones nearby, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement. Anyone responsible for a site like Five Acres Primary School will know that thermal images can show where wet insulation sits under a big flat roof.
