Thermal roof survey in Woollensbrook: what you get
Thermal imaging is useful when a damp patch has no clear cause. Water can travel some distance under a roof covering before it shows inside, and temperature patterns can help us trace where it may have come from. We combine the images with a visual inspection and moisture readings, so the findings don’t rely on the camera alone. We survey loft conversions, insulated roof spaces and commercial roofs, and people most frequently book us about damp around roof outlets and upstands and damp around chimneys and parapets.
Villages like Woollensbrook 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. The visit is planned around the forecast, along with the journey and access. A change in the forecast can mean moving the visit to another day.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

FAQs for Woollensbrook
Will you come out to Woollensbrook?
Yes. Woollensbrook is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and South East England. Just mention lanes, gates or anything else about the route as you book.
Is my home in Woollensbrook listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Which days do you carry out surveys?
We carry out surveys on weekdays and at weekends. To find a day that suits you, phone 07833 053749 or email us.
Is thermal imaging included in your surveys?
It comes with our Premium Survey, which starts from £400. That also includes a full inspection, a drone inspection where applicable, structural analysis and a same-day report.
Will I get photos?
Yes. We photograph the roof as we go, and the report uses them to show each finding alongside our recommendations.
How does a thermal imaging roof survey work?
The images show how warm or cool each part of the surface is. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, which we then check with moisture readings.
How long will you be at the property?
Expect it to take about 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.
What affects the cost of thermal roof surveys
All our prices include VAT. The things that change the price are:
- Which survey package you book
- The height of the building and how the roof can be seen safely
- Any need for thermal images or a drone flight
- How big the roof is
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, inc. VAT. Size, height and access can affect the price too.
What we need to know
The more you let us know, the easier it is to price the survey. When you contact us, let us know:
- Your postcode, so we can check access and travel
- When you need the report by
- Anything about access we should know
- Where any leaks, stains or damp patches show inside
To arrange a survey, ring 07833 053749 or drop us an email and let us know the address and what’s prompted the survey. You will know the price before anything is booked.
How it works
The aim of the visit is simple: to look at the roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It typically takes about one to two hours for a house, and longer for a large or complex roof. Rural addresses near Woollensbrook can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We look at the roof from ground level, from windows and from the roof itself where it is safe.
- A thermal camera records how the surface temperature varies across the roof.
- We check the patterns that stand out with moisture readings where there’s safe access.
- We write up the thermal images alongside ordinary photos and recommendations.
Before the survey
- Tell us about parking before the day
- For flats, check roof access has been agreed
- Leave a clear route to the loft
Book a survey
Photos help, if you have them. Pictures from the ground or a window are fine. To send them or to book, phone 07833 053749 or send us an email.

Thermal roof surveys around Woollensbrook
There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask. Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying.
Take a building like Westfield Community Primary School: big roofs are where photos from the air and thermal images show the most at once. The streets around a church such as Church of St Catherine & St Paul are often among the oldest in a place, and if your house is among the older ones nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that’s where a view by drone or thermal camera helps.

How the survey changes by roof type
Single-ply and EPDM roofs
Thin membranes can show patterns from the layers beneath. Reflections from shiny surfaces can affect readings, which we allow for.
Pitched slate and tile roofs
Thermal images of a pitched roof can still show heat loss patterns and some damp areas. We explain what can and can’t be read from them.
Landlords, agents and block managers in Woollensbrook
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
Before and after the survey
A little preparation and a few simple habits help. Our tips:
- Keep a record of when stains appear
- Talk to us about the weather when booking
- Move stored items away from the loft hatch
- Keep dated photos of any marks on ceilings
If you are buying, the report gives you specific points to raise with the seller or agent. What you do with it is up to you, whether that is asking for work or discussing the price.
Check that loft insulation is laid evenly and hasn’t been pushed aside. Insulation is often moved when people work in the roof space.
