Thermal roof surveys for homes and businesses in Mongewell
Thermal imaging works best in the right conditions. It helps to have a sunny day beforehand, a dry surface and calm air. Rain, a strong wind or heavy cloud can make the images less clear. We’ll discuss the weather with you when booking, and the report explains how the conditions on the day affected the results. If you’ve noticed damp around chimneys and parapets and damp around roof outlets and upstands, a survey will tell you what’s going on, on commercial roofs, loft conversions and insulated roof spaces alike.
Villages like Mongewell frequently stand in open country, where wind can be strong. A small drone can’t 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.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

What we’re asked to look at in Mongewell
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Missing or slipped insulation can stand out as temperature differences, particularly when it is warm inside and cold outside.
Problems we come across often include:
- Water getting in at parapets and stacks
- Damp patches with no obvious cause
- Cold spots on ceilings under the roof
- Thin or uneven insulation in the roof
Take an older house close to St Mary's Church: thin or patchy insulation under an old roof often shows up clearly on a thermal image.
Before booking any roof surveyor
- Whether any drone flown is registered with the CAA
- Their insurance cover
- What experience they bring
- Whether the price includes VAT
The survey, step by step
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes between one and two hours for a house, while a commercial roof takes nearer three to four hours. In a hamlet or village like Mongewell, a postcode does not always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- We carry out a visual inspection of the roof from wherever it can be seen safely.
- A thermal camera records how the surface temperature varies across the roof.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- The report sets out the images, what they suggest and what we recommend.
Preparing for the visit
- Point out any leaks or damp patches
- Keep pets out of the way during the survey
- Buyers: confirm access with the estate agent or seller

Related advice
Can I check my roof myself?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
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 don’t climb up for a closer look.
Landlord and commercial surveys in Mongewell
Businesses and commercial landlords can book us too. Larger roofs take longer, so they’re priced to suit.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.
Thermal roof surveys around Mongewell
Historic houses such as Brightwell Manor, about 2.6 miles north-west, show how far back building in the area around Mongewell goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. West Oxfordshire’s older buildings frequently carry Cotswold stone slates, and a few villages in the county keep their thatch. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. 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.
For site and facilities teams at buildings such as Crowmarsh Gifford Church of England School, thermal images can show where wet insulation sits under a big flat roof.

What a survey costs depends on the time and equipment it needs. The main factors are:

Prices start from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, including VAT.
Getting in touch

- Any stains, drips or damp patches you’ve seen indoors
- Pictures from the garden or a window, if you have them
- The property’s address and postcode

Your questions about thermal roof surveys in Mongewell
Does a conservation area affect roof work in Mongewell?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Is Mongewell within the area you cover?
Yes, Mongewell is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Can you use a thermal camera on a sloping roof?
On pitched roofs, the camera can point to heat loss and some damp patterns. We explain what the images can and can’t tell you, and back them up with a visual inspection and moisture readings.
What happens after the survey?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
What will the report tell me?
You get our findings in writing, part by part, with photos, finishing with recommendations. Points are put with the most urgent first where relevant.
Can you do a thermal survey in any weather?
Conditions on the day affect the results. A sunny day beforehand, a dry surface and calm air all help. Rain and strong wind can make the images less clear, so we talk through the forecast when booking.
Can you survey at the weekend?
We carry out surveys on weekdays, Saturdays and Sundays. To arrange a date, call 07833 053749 or drop us an email.

What happens if roof problems are left?
Heat lost through a roof costs money every winter. Thermal images can show where insulation is missing or has slipped, so improvements can go where they’re needed. Older cottages and farmhouses around Mongewell can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, inc. VAT. The roof’s size, height and access matter as well.
Why us?
- Package prices that include VAT
- 20+ years’ experience
- An independent look at the roof
- Thermal imaging and drone inspection where they help
