Thermal roof survey in Warner's End
A thermal survey can point to places where heat is escaping through the roof. Gaps in loft insulation and poorly insulated areas can stand out on the images. It works best when the building is heated and it is colder outside. The report shows the images and explains what they may mean. It is not an energy rating or a heat loss calculation. Common reasons to book are areas of a flat roof that may hold water and water getting in at parapets and stacks, on commercial roofs, ceilings below the roof and loft conversions.
In smaller places like Warner's End, many homes are bungalows and houses with roofs you can partly see from the ground. Chimney tops, valleys and rear slopes are where close-up or thermal images help most. The forecast decides the day. Even so, a close-up image often shows wear on ridges and flashings that a view from ground level misses.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Landlord and commercial surveys in Warner's End
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
If the property is let, the agent or a tenant can let us in, at a time agreed in advance. Surveys run on weekdays and at weekends, which can make access easier.
What we look for on each type of roof
Parapets, valleys and junctions
Problems where roof slopes and walls meet are frequently hidden. We combine a close visual check with the thermal images.
Single-ply and EPDM roofs
On big single-ply roofs, the camera helps show where to take readings. It focuses the survey on the areas that matter.

How we price thermal roof surveys
Several things affect the price of a survey:
- The use of thermal imaging or a drone
- The roof’s overall size
- Which survey package you book
- How complicated the roof is, with its valleys, chimneys and parapets
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. We will give you the figure before anything is booked.
Booking your survey
When you call or email, these details help:
- Anything about access we should know
- Where water is showing inside, if it is
- What kind of property and roof it is
- The reason for the survey, like buying, a leak or storm damage
If you have photos of the roof, send them over. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, phone 07833 053749 or email us.
Warner's End: your questions answered
Is Warner's End in the area you cover?
Yes. Our area covers London and the South East, and Warner's End is part of that. You can ring 07833 053749 or use the contact form with the address and a few details, and we’ll talk through which survey suits.
Does a conservation area affect roof work in Warner's End?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Can you check my loft insulation with a thermal camera?
Thermal images can suggest where heat is escaping and where insulation may be missing. We don’t give energy ratings or heat loss calculations, but the report shows where to look more closely.
How soon will I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
How many surveys have you done?
More than 5,000 surveys over 20+ years.
Do you carry out surveys on Saturdays and Sundays?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days when booking.
Which survey includes thermal imaging?
It comes with our Premium Survey, which starts from £400. That also includes a full inspection, a drone inspection where it applies, structural analysis and a same-day report.
Should I look at the roof myself first?
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in, using safe viewpoints and a drone where it applies.
Drones, thermal imaging and Warner's End roofs
Warner's End is part of Hemel Hempstead, one of the post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Low pitches and flat-roofed additions are hard to see from ground level, so aerial and thermal views add detail. If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying.
For an older house near a landmark such as St Alban's Church, thin or patchy insulation under an old roof often shows up clearly on a thermal image.
Warner's End is about 1 mile west of Hemel Hempstead, in Hertfordshire. Warner's End is part of the area we cover across London and South East England. Our area takes in places right across Hertfordshire. There is also a page for Milton Keynes.

What we’re asked to look at in Warner's End
Unexplained damp is one of the main reasons people ask for thermal imaging. A leak may start well away from where the stain appears. The camera helps narrow the search.
These are some of the problems a survey can pick up:
- Damp where roofs meet walls and chimneys
- Cold spots on ceilings under the roof
- Wet areas near outlets and upstands
- Damp patches with no obvious cause
Take a building like Micklem Primary School: a drone or thermal camera can show a large roof in a single visit.
What to check before booking
- Whether VAT is in the quoted price
- What insurance they carry
- Which viewpoints they use to see the roof
- Do they have a CAA Flyer ID and Operator ID for drone work?
How the survey works
We will ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes roughly 1–2 hours at a typical home, and about three to four hours for a commercial roof. With a bit of garden around a house, as there often is around Warner's End, the roof can be viewed from several angles. Mention any side of the property we cannot get to. The loft, where there is safe access, completes the picture.
- You let us know about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Getting ready for the survey
- Have keys ready for side gates, garages or roof access doors
- Mention any parking restrictions on your street
- If the roof is shared, arrange access with whoever manages the building
Book a survey
Booking is simple: just call 07833 053749 or email us, tell us about the property and we’ll recommend the right survey. We confirm the price before anything is booked.
