Thermal roof survey in Theydon Bois
Our Premium Survey, from £400, brings together a full roof inspection and thermal imaging. It also includes a drone inspection where applicable, a structural analysis and a same-day report. An in-person consultation and a 12-month follow-up are included too. To book, just call 07833 053749 or send us an email with the address and what you’ve noticed. For big commercial roofs, we quote on size and access. If you’ve noticed cold areas below the roof and leaks far from where the stain appears, we can find out what’s behind it, on pitched roof slopes, flat roofs and insulated roof spaces alike.
Even in a smaller place like Theydon Bois, there may be airfields or restrictions nearby, so the Drone Safety Map is checked before any flight. Open ground can mean stronger wind, which also affects whether a small drone can fly, while thermal imaging also works best with little wind. Each flight is planned with neighbours’ privacy in mind, as well as the airspace and the wind.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

What we do, step by step
The visit has one job: 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 normally takes about 1–2 hours at a typical home, or half a day or so for a commercial building. A visit to Theydon Bois is planned like any other: the time, the access and where to park are agreed beforehand. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.
- 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.
- Thermal images are taken to show differences in surface temperature.
- Any patterns of interest are checked with moisture readings where we can reach them.
- We write up the thermal images alongside ordinary photos and recommendations.
Before the survey
- Keep pets out of the way during the survey
- Check the loft hatch can be reached
- Let us know about parking near the property

For landlords and managing agents
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
An agent can book and manage the survey for a landlord, and the report can go to both. Access is agreed with the tenant ahead of time.
Can I check my roof myself?
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we look at the roof.
What affects the cost of thermal roof surveys
When we price a survey, we consider:
- Whether you choose the Basic, Standard or Premium Survey
- How big the roof is
- The type of building, from a house to a block or an office
- How many separate roofs there are, such as extensions, dormers and garages
Our price is from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included.
Getting in touch
What helps most when you contact us:
- Where the property is, with the postcode
- What kind of property and roof it is
- What made you get in touch
- Access details, such as a loft hatch or a shared roof
When you’re ready to go ahead, phone 07833 053749 or send us an email. From there it’s a case of choosing a package, agreeing the price and fixing a day.
Drones, thermal imaging and Theydon Bois roofs
Stapleford Aerodrome is about 3 miles from Theydon Bois. Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying. Historic houses like Hill Hall, about 2.3 miles east, show how far back building in the area around Theydon Bois 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 the council can say whether a home is in a conservation area.
Take a building like Theydon Bois Primary School: thermal images can show where wet insulation sits under a big flat roof. If you live in an older home near Parish Church of St Mary, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Theydon Bois is about 2 miles north-east of Loughton, in Essex. Bookings from Theydon Bois are handled just like any other: a call or an email, a price, then a date. Our Essex coverage includes Theydon Bois and the places around it. For surveys nearby, see our London page.

Your questions about thermal roof surveys in Theydon Bois
Are there drone restrictions around Theydon Bois?
It depends on the exact address and the weather on the day. Stapleford Aerodrome is about 3 miles away, so we check the Drone Safety Map for restrictions before any flight. A small drone can’t fly safely in high wind or heavy rain, though the rest of the survey goes ahead either way.
Is Theydon Bois within the area you cover?
We do. Villages and rural addresses get the same survey as a town house.
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. It is used alongside a close inspection and moisture readings, as the camera alone cannot prove a leak.
What happens after the survey?
We email you the written report with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Can you survey at the weekend?
We carry out surveys on weekdays and at weekends. To find a day that suits you, call 07833 053749 or send us an email.
How many surveys have you done?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.
Will you photograph what you find?
Yes. Photographs are taken throughout the survey, and they go into the written report.
Useful tips for Theydon Bois property owners
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
- Check outlets after heavy rain
- Do not switch the heating off before the visit
If the images suggest moisture that cannot be confirmed, we will say what would help next, such as electronic leak detection or opening up a small area.
Consider a repeat survey after major work on the roof in suitable weather.
How the survey changes by roof type
Single-ply and EPDM roofs
Because these membranes are thin, patterns from below often show. Reflections from shiny surfaces can affect readings, which we allow for.
Felt and asphalt flat roofs
On felt and asphalt flat roofs, wet insulation can show as a temperature difference across the surface. Moisture readings are used to check them.
