About our thermal roof survey in Kemprow
Thermal imaging is often most useful on flat roofs, from small extensions to large commercial roofs. It can show patterns that point to trapped moisture under the membrane. Pitched roofs with slates or tiles are often harder to read, because of the air space beneath, so we combine the camera with an inspection from the loft where there’s safe access. If you’ve noticed heat escaping through the roof and stains that keep coming back, we can find out what’s behind it.
In a small place like Kemprow, open ground can mean strong wind. A small drone cannot fly safely in strong wind or a downpour, and thermal imaging works best with little wind. The visit is planned around the forecast, along with the journey and access. A change in the forecast can mean moving the visit to another day.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

What happens on the day
We check the roof from outside and, where it’s relevant and there’s safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey typically takes roughly 1–2 hours for a house, with bigger or more complicated roofs taking longer. Cottages and farmhouses around Kemprow often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- 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.
How to prepare
- Have any paperwork from past roof work to hand
- Tell us about parking before the day
- Keep pets out of the way during the survey

Why get it checked now?
The longer moisture sits in a roof, the more it can affect timbers and finishes below. Surveying sooner gives you more choice about what to do. Older cottages and farmhouses around Kemprow can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it is left.
Prices quoted always include VAT, and the report is not charged as an extra. Thermal roof survey starts from £400, including VAT. Size, height and access decide where your roof falls.

Drones, thermal imaging and Kemprow roofs
Elstree Aerodrome is about 2 miles from Kemprow. If your survey includes the drone, the Drone Safety Map is checked for restrictions first. With High Elms Manor about 2.7 miles north-west, Kemprow sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
For businesses in and around places like Harlequin Centre, big, flat commercial roofs are where aerial photos and thermal images help most. If your home is one of the older ones in the streets near St John, older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help.

When to book a survey in Kemprow
Building owners and managing agents use thermal surveys to plan work on larger flat roofs. It can suggest which areas may be wet and which seem dry, so moisture readings can be targeted.
These are some of the problems a survey can pick up:
- Thin or uneven insulation in the roof
- Leaks far from where the stain appears
- Stains that keep coming back
- Wet areas near outlets and upstands
Take a building like Fair Field Junior School: a drone or thermal camera can show a large roof in a single visit.

FAQs for Kemprow
Is my home in Kemprow listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is drone flying allowed in Kemprow?
The answer turns on the exact location and the conditions on the day. Kemprow is about 2 miles from Elstree Aerodrome, so the Drone Safety Map is checked for restrictions around it before we fly. The flight also waits for calm, dry weather.
What does the report include?
Written findings with photos, covering the condition of the roof, the defects we found and what we recommend. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where it applies and structural analysis.
Can you do a thermal survey in any weather?
Conditions on the day affect the results. A sunny day beforehand, a dry surface and calm air all help. Rain and strong wind can make the images less clear, so we discuss the forecast when booking.
Can you survey a shared roof?
Yes, as long as access is agreed. Roofs over flats are often shared, so whoever owns or manages the building needs to agree access. We can only inspect what we are given access to.
Is this an asbestos survey?
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.
How many surveys have you done?
Over 20 years and more than 5,000 surveys, across London and South East England.
Honest limits
It is a careful look at the roof, not the whole story. Its limits include:
- An energy rating for the building
- A structural engineer’s assessment
- Seeing water directly, as the camera shows temperature, not moisture

What affects the price in Kemprow

- Basic, Standard or Premium

There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. The price for your roof depends on its size, access and what you’d like to know.
What we need to know
There’s no need for technical words. Just tell us:
- The style of property, from a terrace to a block
- Your timetable, such as an exchange date
- Any stains, drips or damp patches you’ve seen indoors
- Pictures from the garden or a window, if you have them
Prices start from £400, including VAT. What you pay depends on the roof’s size, access and the package, so ring 07833 053749 or drop us an email with the details.
Should I look at the roof myself first?
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we check the roof.
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.
