Thermal roof surveys for homes and businesses in Ayot Green
Our Premium Survey, from £400, brings together a full roof inspection and thermal imaging. You also get a drone inspection where applicable, structural analysis and a report on the same day. 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. Larger commercial roofs are quoted for their size. We are often asked to look into missing or slipped insulation and wet insulation beneath the membrane, across insulated roof spaces, flat roofs and commercial roofs.
In a small place like Ayot Green, open ground can mean strong wind. A small drone cannot fly safely in strong wind or heavy rain, and thermal imaging works best with little wind. We plan the journey, access and timing around the weather. A change in the forecast can mean moving the visit to another day.
The report does not just list problems. It explains what we found, why it matters and what we recommend.

Should I look at the roof myself first?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
What we look for on each type of roof
GRP fibreglass roofs
Glossy GRP can reflect heat. We allow for reflections and confirm findings with moisture readings.
Single-ply and EPDM roofs
Single-ply PVC, TPO and EPDM roofs are often laid over insulation boards. Wet boards can show as temperature differences on the images.
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. The inspection then takes between one and two hours for a house, with bigger or more complicated roofs taking longer. Older roofs in small places like Ayot Green can have low, tight loft spaces, so let us know about the loft hatch and any ladder. We only go where it’s safe.
- 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.
- You get a report with thermal images, photos and our recommendations.
Before the survey
- Make sure we can get to the back of the property
- Tell us about any leaks, stains or damp patches you know of
- Make a note of anything you’d like us to look at
Getting a price
Getting a price is simple: just call 07833 053749 or use the contact form and give us a few details about the property and we will explain which survey suits. The price is agreed up front.
Advice
How we price thermal roof surveys
We confirm the price for your roof before you book. These are the things that affect it:
- Commercial roofs and larger buildings
- Extensions, dormers and garages with roofs of their own
- The package you choose: Basic, Standard or Premium
- Any need for thermal images or a drone flight
Our price is from £400, including VAT. The final price depends on the size and height of the roof, access and the package you choose.
What we need to know
You do not need to know any roofing terms. Just tell us:
- The property’s address and postcode
- When you need the report by
- What made you get in touch
- How the loft is reached, if there is one
Thermal roof survey starts from £400, including VAT. The exact figure depends on the roof and the package, so ring 07833 053749 or send us an email with the details.
Landlord and commercial surveys in Ayot Green
An agent can book and manage the survey for a landlord. We agree a time with the tenant beforehand.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
Before and after the survey
From years of surveys, a few habits stand out as worth the effort:
- Check from the ground or a window, never by climbing
- Remember the conditions on the day affect the results
- Keep outlets and gutters clear to stop water sitting
- Take photos of stains as they appear, so we can compare
Once we’ve been, the thermal images, photos and readings go into a single report. We explain what each image may mean, alongside what we recommend. With a Premium Survey, you get the report the same day.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
Drones, thermal imaging and Ayot Green roofs
If your survey includes the drone, the flight is checked against the Drone Safety Map first. The wider area around Ayot Green has a long history of building, with Digswell House about 1.1 miles east. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
If yours is one of the older homes in the streets near Church of St Peter, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help. Shop and office owners around Howard Centre may find that big, flat commercial roofs are where close-up aerial shots and thermal images help most. Anyone responsible for a site like Monk's Walk School will know that thermal images can show where wet insulation sits under a big flat roof.

FAQs for Ayot Green
Is Ayot Green in the area you cover?
Yes, Ayot Green is within the area we cover. Our area covers London and South East England. Just phone 07833 053749 or use the contact form and let us know about the property.
Does a conservation area affect roof work in Ayot Green?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
What does a thermal roof survey show?
The camera records how the surface temperature varies. The patterns can suggest wet insulation, gaps in insulation or heat escaping. Findings are checked with moisture readings.
Can a thermal camera see water?
Thermal imaging shows temperature rather than water. Because wet insulation holds heat for longer, it can show as a different temperature, and moisture readings are used to check it.
Can you use a thermal camera on a sloping roof?
It can show heat loss and some damp, but it has more limits there. We explain what the images can and cannot tell you, and we check them with a visual inspection and moisture readings.
What conditions are best for thermal imaging?
Conditions on the day have a big effect on what the camera can show. Dry, calm weather after some sun gives the best chance of clear images. We record the conditions in the report, so you know how much weight to give the images.
Will you walk on the roof?
Only if it is safe. We check everything that can be seen safely: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. Anything we can’t see is noted in the report.
