How a thermal roof survey works in Preston
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging frequently helps most. Patterns can suggest where water is trapped under the covering. Pitched roofs with slates or tiles are frequently harder to read, because of the air space beneath, so we combine the camera with an inspection from the loft where there is safe access. We survey pitched roof slopes, ceilings below the roof and insulated roof spaces, and people most often book us about stains that keep coming back and ceilings that feel colder in places.
Villages like Preston often stand in open country, where wind can be strong. Strong wind or heavy rain stops a small drone flying, and calm conditions also suit thermal imaging best. The visit is planned around the forecast, along with the journey and access. If the day turns windy or wet, the visit can be moved.
What you get is a clear record of the roof on the day we saw it. That makes it useful now and a handy reference later, for example when you want to check whether anything has changed.

Your questions about thermal roof surveys in Preston
How do I find out if my home in Preston is listed?
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.
Do you cover smaller places like Preston?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Can you inspect my roof with a drone?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules. We are a CAA-registered drone operator.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Does someone need to be in?
That depends on the survey. For inside areas and the roof space, someone has to give us access, while outside access can be discussed when booking.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
Can you survey at the weekend?
Surveys run on weekdays and at weekends. To arrange a date, ring 07833 053749 or use the contact form.
Tips that help
Nothing here needs a ladder. A few suggestions:
- Keep dated photos of any marks on ceilings
- Make sure the loft can be reached safely
- Remember the conditions on the day affect the results
- Use the report as a baseline for later checks
The report explains the conditions on the day and how they affected the images. It helps you judge how firm each finding is.
Clear outlets and gutters regularly, so water doesn’t sit on the roof. The less water sits, the less can find its way beneath.
Thermal roof surveys around Preston
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help. Preston is about 2 miles from the edge of the flight restriction zone around Luton Airport. If your survey includes the drone, we check the exact boundary for the address before flying.
The streets around a church such as Church of St Martin are often among the oldest in a place, and if your house is among the older ones nearby, thin or patchy insulation under an old roof often shows up clearly on a thermal image. Anyone responsible for a site like Preston Primary School will know that a drone or thermal camera can show a large roof in a single visit. Knebworth House lies about 3.9 miles south-east, so building around Preston goes back a long way. Older roofs nearby can be steep and hard to see from ground level, and a survey from above or with a thermal imager doesn’t touch the roof itself.
Preston is about 3 miles south of Hitchin, in Hertfordshire. We cover Preston and the rest of Hertfordshire. Preston is one of the towns and villages in Hertfordshire we cover. For surveys nearby, see our Milton Keynes page.

- What kind of property and roof it is
- Any marks or damp showing indoors
- Your postcode, so we can check access and travel
Most bookings start with a short call: ring 07833 053749 or send us an email. The price is agreed before a date is set.

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, and look for staining, damp timber or daylight coming through.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
Rented homes, blocks and businesses
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client.
We survey roofs for landlords and agents as well as householders. The report gives you a dated record of the roof, with photographs, useful for planning maintenance.
Why act early in Preston
If a big flat roof may need replacing, knowing the wet areas first is useful. Images backed by moisture readings show where problems seem to be before you spend. Where a roof is exposed, as many are in small places like Preston, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
What you get with us

How the survey works
On the day, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can safely be seen, using the ground, windows, the loft and a drone where it applies. Most surveys take about one to two hours for most homes, plus time to check any thermal findings with moisture readings. Rural addresses near Preston can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- The roof is inspected visually from safe viewpoints.
- A thermal camera records how the surface temperature varies across the roof.
- Any patterns of interest are checked with moisture readings where we can reach them.
- The report sets out the images, what they suggest and what we recommend.
Preparing for the visit
- Keep pets inside or away from the areas we are looking at
- Move anything stored under the loft hatch
- Agree roof access with the managing agent if it’s shared
