Liss Thermal Roof Survey
Know where you stand with the roof before you decide what to do next. We carry out thermal roof surveys in Liss, with photos and a clear written report.
- Thin or uneven insulation in the roof
- Possible trapped moisture under a flat roof covering
- Damp that repairs haven’t cured
Landlords, agents and block managers in Liss
We survey roofs for landlords and letting agents as well as homeowners. The report gives you a dated record of the roof, with photographs, which helps you plan work between tenancies.
Letting agents frequently book on a landlord’s behalf, with the report sent to whoever needs it. Access is agreed with the tenant ahead of time.
Thermal roof survey in Liss
Wet insulation under a flat roof covering holds heat for longer than dry. That means a wet area can show up as a different temperature from the rest of the roof. This can give an idea of how far water has travelled beneath the membrane, something you cannot typically tell from the surface. Moisture readings are then used to check what the camera suggests. If you’ve noticed moisture around outlets and upstands and missing or slipped insulation, a survey will tell you what’s going on.
Around Liss, older homes can have thin loft insulation and later additions with roofs of their own. A thermal image can show where heat is escaping or where moisture may be trapped, and drone photos show the roof surfaces themselves. Findings are checked with moisture readings where needed. Calm, dry weather suits both methods, so the date is set with the forecast in mind.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

How we price thermal roof surveys
What a survey costs depends on the time and equipment it needs. The main factors are:
- How many separate roofs there are, such as extensions, dormers and garages
- The size of the roof
- How tall the building is and how easy the roof is to see
- If the survey needs thermal imaging or a drone
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Thermal roof survey starts from £400, including VAT.
Getting in touch
A few details help us point you to the right survey and price. When you get in touch, it’s useful to mention:
- Your postcode, so we can check access and travel
- Your timetable, such as an exchange date
- Where any leaks, stains or damp patches show inside
- How the loft is reached, if there is one
Our phone lines are open seven days a week. To book or ask a question, call 07833 053749 or send us an email.
What we’re asked to look at in Liss
Some defects simply cannot be seen with the eye. Trapped moisture, missing insulation and hidden heat loss are three examples. Thermal imaging gives us another way to look for them.
Problems we come across often include:
- Water that travels before it shows
- Thin or uneven insulation in the roof
- Damp around roof outlets and upstands
- Ceilings that feel colder in places
Take a building like Liss Infant School: thermal images can show where wet insulation sits under a big flat roof.
What to check before booking
- What happens after the report arrives
- How long the report takes to arrive
- How long they’ve been surveying roofs
- What’s outside the scope of the survey
The survey, step by step
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take about 1–2 hours for most houses, with bigger or more complicated roofs taking longer. In a smaller place like Liss, as anywhere, the forecast plays a part: the parts that need calm, dry weather are planned around it.
- You tell us about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
How to prepare
- Tell us about any leaks, stains or damp patches you know of
- Agree roof access with the managing agent if it is shared
- Make a note of anything you’d like us to look at
How to book
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To send them or to book, call 07833 053749 or use the contact form.

Different roofs, different checks
GRP fibreglass roofs
GRP roofs are laid over timber boards, so trapped moisture can affect the deck. Thermal imaging can suggest where that may be happening.
Felt and asphalt flat roofs
Built-up felt and asphalt roofs can hide trapped water for a long time. Thermal imaging helps suggest where it is, given suitable conditions on the day.
Your questions about thermal roof surveys in Liss
Is Liss in the area you cover?
We do. The survey and report are the same in Liss as anywhere else.
Is Liss within the area you cover?
We do. Villages and rural addresses get the same survey as a town house.
How much does a thermal roof survey cost?
It’s part of the Premium Survey, from £400. An in-person consultation and a follow-up 12 months later are included too. Larger commercial roofs are quoted for their size.
What happens next?
The report arrives by email, with photos and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, backed by photos. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
How many surveys have you done?
Over 5,000 surveys so far, across 20+ years of surveying roofs, with 98% customer satisfaction.
Do you climb onto every roof?
Only where it is safe to do so. We check everything that can safely be seen: from the ground, from windows, from inside the loft space, from the roof where it’s safe and by drone where it applies. The report says if anything couldn’t be seen.
When you need someone else
Before you book, it’s worth knowing what a survey won’t do:
- Reliable images in rain, strong wind or on a wet roof surface
- Insulation values or heat loss calculations
- Proving moisture from the images alone

What a thermal roof survey looks like in Liss
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned.
Take an older house close to Church of St Mary: older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help.
