Thermal roof survey in Horn Hill: what you get

Our thermal survey records how the surface temperature varies across your roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. The camera does not see water itself, so findings are checked with moisture readings. Thermal imaging is included in our Premium Survey, from £400. The report also notes the conditions on the day, since they affect what the camera can show. We survey loft conversions, ceilings below the roof and flat roofs, and common reasons people get in touch are water getting in at parapets and stacks and wet insulation beneath the membrane.

Older buildings in small places like Horn Hill may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, so it’s a gentle way to see the condition of an old roof, before anyone decides what work it needs. Check with the council before planning any work on a listed building or one in a conservation area.

The report is written in plain words, so it makes sense without any roofing background. Each point is backed by a photo where possible.

Do you need a thermal roof survey in Horn Hill?

After a repair, some owners want to know whether the roof has dried out. A thermal survey with moisture readings can show whether wet areas remain, given suitable conditions on the day.

Here are some of the things we see frequently:

  • Ceilings that feel colder in places
  • Wet areas near outlets and upstands
  • Water getting in at parapets and stacks
  • Damp patches with no obvious cause

Take a building like Maple Cross Junior Mixed Infant and Nursery School: thermal images can show where wet insulation sits under a big flat roof.

Choosing a roof surveyor

  • Whether you can ask questions once you have the report
  • Will the report include photos?
  • How long they’ve been surveying roofs
  • Whether the inside of the roof is included

What’s in a roof survey

How the survey works

Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. The whole visit normally takes about one to two hours for most homes, plus time to check any thermal findings with moisture readings. Older rural homes like those around Horn Hill can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.

  1. We talk through the roof, any damp or leaks, and the weather expected on the day.
  2. We carry out a visual inspection of the roof from wherever it can be seen safely.
  3. We take thermal images of the roof to pick up temperature patterns.
  4. Any patterns of interest are checked with moisture readings where we can reach them.
  5. The report sets out the images, what they suggest and what we recommend.

Preparing for the visit

  • Find any records of previous roof work
  • Agree roof access with the managing agent if it’s shared
  • Keep pets inside or away from the areas we’re looking at

Checking the roof from ground level

If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.

Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we look at the roof.

Horn Hill: your questions answered

Can you fly a drone over a roof in Horn Hill?

The answer turns on the exact location and the conditions on the day. Horn Hill is about 3 miles from Denham Aerodrome, so the Drone Safety Map is checked for restrictions around it before we fly. The flight also waits for calm, dry weather, and the rest of the survey doesn’t depend on the drone.

Does a conservation area affect roof work in Horn Hill?

For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.

How do I book a survey in Horn Hill?

It is easiest to phone 07833 053749 or send us an email. Let us know the address and a little about the roof. We survey on any day of the week.

Does someone need to be in?

That depends on the survey. For inside areas and the loft space, someone has to give us access; we will agree the details as you book.

How experienced are you?

More than 5,000 surveys over 20+ years.

How long does the survey take?

Most surveys take roughly 1–2 hours for a house, or half a day or so for a commercial building. We’ll confirm the timing as you book.

What happens next?

You will receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.

What affects the cost of thermal roof surveys

Prices vary from roof to roof, for these reasons:

  • The package you choose: Basic, Standard or Premium
  • How tall the building is and how easy the roof is to see
  • Features like valleys, chimneys, dormers and parapets
  • Whether thermal imaging or a drone is needed

Thermal imaging and drone inspection (where it applies) come with the Premium Survey, from £400 inc. VAT. We’ll tell you which package suits the questions you have.

What we need to know

Getting the details right at the start saves time. Please include:

  • When you need the report by
  • Why you want a survey: buying, a leak, a storm or new work
  • Any marks or damp showing indoors
  • The property’s address and postcode

To arrange a survey, ring 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.

Airspace, weather and Horn Hill roofs

About 3.6 miles north lies Chenies Manor House, a reminder of how long the area around Horn Hill has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Some villages in Buckinghamshire still have thatched roofs. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Many roofs like these cannot be judged properly from the pavement, and that is where a view from above or a thermal image earns its place.

If your home is one of the older ones in the streets near St Paul's, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view by drone or thermal camera helps.

Leave it or get it looked at?

Once insulation under a membrane is wet, it tends to stay wet. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. Around Horn Hill, older homes often have old roof timbers, where water from a failed roof can cause rot if it’s left.

Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. The price is always agreed first.
