About our thermal roof survey in High Ongar
Our Premium Survey, from £400, brings together a full roof inspection and thermal imaging. You also get a drone inspection where it applies, structural analysis and a report on the same day. There is an in-person consultation as well, plus a follow-up 12 months later. You can ring 07833 053749 or use the contact form with the address and a note of what you’ve noticed. Larger commercial roofs are quoted for their size. We survey commercial roofs, loft conversions and ceilings below the roof, and common reasons people get in touch are water that travels before it shows and gaps in loft insulation.
Villages like High Ongar often stand in open country, where wind can be strong. A small drone cannot fly safely in strong wind or heavy rain, and thermal imaging works best with little wind. 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.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Thermal roof surveys in High Ongar: local notes
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so the council is the place to ask.
Take a building like High Ongar Primary School: big roofs are where photos from the air and thermal images show the most at once.

Locally, jobs take us to homes and businesses close to Red Lion Public House and The Ongar Academy, among other places. A little further out are Willingale Doe (3.7 miles north-east).
What happens on the day
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can safely be seen, from ground level, from windows, in the loft space and by drone where it applies. The survey typically takes an hour or two at a house, including the thermal images, and around 3–4 hours for a commercial roof. Older roofs in small places like High Ongar can have low, tight loft spaces, so tell us about the loft hatch and any ladder. We only go where it is safe.
- 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.
- Patterns that stand out are checked with moisture readings.
- Each image is set beside a normal photo and explained in the report.
Before the survey
- Keep pets inside or away from the areas we are looking at
- Point out any leaks or damp patches
- Make a note of anything you’d like us to look at

Surveys for landlords and agents in High Ongar
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client.
We survey roofs for landlords and agents as well as householders. The report gives you a dated record of the roof, with photographs, which helps you plan work between tenancies.
Common roof problems in High Ongar
On big commercial and residential flat roofs, thermal imaging helps owners plan. It can suggest which areas may be wet and which seem dry, so moisture readings can be targeted.
A survey makes sense if you’ve noticed:
- Damp that repairs haven’t cured
- Water that travels before it shows
- Damp where roofs meet walls and chimneys
- Wet areas near outlets and upstands
For an older house near a landmark like Church of St Mary the Virgin, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help.
What to check before booking
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Which parts of the roof they’ll actually see
- What the report includes, and whether it has photos
- Which limits apply to the survey
Why act early in High Ongar
Repeated repairs that don’t stop a leak are a sign the source hasn’t been traced. Combining the camera with moisture readings can help find it, instead of trying repair after repair. In a small place like High Ongar, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. The price for your roof depends on its size, access and what you’d like to know.
Why book us in High Ongar
- Drones and thermal imaging where it applies
- More than 5,000 surveys completed
- Photos and a written report every time
- Clear package prices, including VAT

High Ongar questions
Do you cover smaller places like High Ongar?
Yes, High Ongar is covered. Our area covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you carry out roof surveys in High Ongar?
Yes, High Ongar is within the area we cover. Our area covers London and South East England. You can ring 07833 053749 or send us an email with the address and some details, and we’ll talk through which survey suits.
Is this an asbestos survey?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
What’s the best way to book?
Just call 07833 053749 or drop us an email with the address. After a few questions, we confirm the price and fix a day.
Will you walk on the roof?
Only when it’s safe. Safe viewpoints, the loft space and a drone where it applies cover most of what’s needed, and the report notes anything we couldn’t see.
What happens next?
The report arrives by email, with photographs and clear recommendations. With Standard there is a follow-up consultation; with Premium, an in-person consultation.
Can you survey at the weekend?
We survey seven days a week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
What we cannot see
Every survey has limits, and we’d rather be clear about that before booking. Bear these in mind:
- Readings unaffected by sun, shade or reflections
- What’s inside walls or under coverings, without opening up
- Seeing water directly, as the camera shows temperature, not moisture
If in doubt, phone 07833 053749 or drop us an email and we will point you to the right survey. What a survey covers and does not.
What we look at
- Ceilings below the roof
- Loft conversions
- Flat roofs
- Pitched roof slopes
- Commercial roofs
- Insulated roof spaces
DIY checks: what’s safe
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
A DIY look is useful, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
