Chimneys are an essential component of a home's heating system, serving to vent gases and smoke generated by fuel-burning appliances and fireplaces. However, over time, chimneys can become damaged or clogged, leading to a potential fire hazard. This is where a chimney survey and drones come in as crucial tools for homeowners and professionals alike.
Why are chimney inspection drones needed?
Chimney inspection drones deliver an accurate and affordable way of inspecting a chimney and identifying myriad problems, helping professionals view the chimney up close without needing to endanger themselves or others by physically being on the roof.
There are various elements of a chimney that can fail, including the chimney stack, chimney pots which enable proper ventilation, lead flashing which keep it watertight and cowls and caps which prevent birds and rainwater from entering the flue. An inspection might be required for insurance purposes, as part of a condition report for buying or selling the property, or if wear and tear has become visible. Property owners may need an inspection as part of planning listed works, there may be water issues or loose flashing in the chimney, or damage from weather or bird issues.
A chimney inspection is an assessment of the structure and condition of the chimney, where a professional inspector will assess the condition of the chimney liner, flue and exterior brickwork to determine if there is any damage or blockage. They will also check for any signs of wear and tear, such as cracks or missing mortar, which can lead to a dangerous build-up of carbon monoxide and other toxic gases.
Drones, on the other hand, have become increasingly popular in recent years, as they offer an efficient and cost-effective method of inspecting chimney structures. Drones can reach difficult-to-access areas and provide high-quality visual data that can be analysed to determine the condition of the chimney. A drone can capture high-resolution images, which can be used to assess the condition of the chimney.
Benefits of chimney drone inspections
There are several reasons why more and more businesses are opting to use drone technology to carry out chimney surveys. Here are just a few of the advantages they have to offer over a traditional inspection.
Safer and greater accessibility
Firstly, it ensures the safety of the occupants of the property – chimney fires can be devastating, and they often go undetected until it's too late. A survey can detect any potential problems before they become a hazard.
Drones, in particular, make the process of inspecting chimneys much safer, especially in instances where the chimney is challenging to access. Drones are able to capture images in areas that are difficult or even impossible to access manually, such as the top of the chimney stack, which is often inaccessible due to height and lack of proper anchoring equipment. Drones can fly to these areas and capture detailed images, allowing inspectors to assess the condition of the chimney from all angles.
Cost-saving
A chimney survey can save property owners money in the long run. If problems are caught early, they can be repaired at a lower cost than if left unattended, where the damages can accumulate, leading to the eventual need for a replacement.
Hiring a drone for the inspection is less expensive since there’s no need for scaffolding and other access equipment. Similarly, this improves the speed at which they can complete the inspection. In the past, inspectors would have to climb onto the roof and use a ladder to access the chimney which is a time-consuming and potentially hazardous task. With drones, an inspection can be completed quickly and with minimal risk.
Early detection of problems
Drones are equipped with advanced technology such as thermal imaging cameras, which can detect heat signatures from the chimney. This technology can identify hotspots, which may indicate a blockage or a build-up of creosote, a highly flammable substance that can lead to chimney fires. This early detection can prevent a potentially dangerous situation from occurring. Thermal cameras can also highlight areas where heat is escaping, so you know where issues lay. This prevents unnecessary bills and allows for problems to be resolved at the root cause.
Reliable data
The use of drones in chimney surveys also improves the accuracy and reliability of the inspection. The images captured by the drone are stored and analysed, providing a clear picture of the condition of the chimney. This data can then be used to create a detailed report that outlines any potential problems and recommends the necessary repairs. This ensures that property owners are aware of any issues that need to be addressed, allowing for timely repairs to be made.
What to look for in drone equipment
The best drone for inspections can fly for at least 25 minutes with a full charge, and with high camera quality to take clear images and videos. Higher quality cameras allow the inspection to be carried out much faster and with a lower risk of damage to the drone itself. Flight stability is also needed to control the camera and keep it steady in harsher weather conditions. Likewise, obstacle avoidance is essential to keep the drone from crashing into the chimney or other parts of the roof.
We offer fully licensed and insured drone pilots with the latest in drone technology to carry out chimney and roof inspections efficiently. Providing high definition and high resolution images and videos, our inspections deliver an in-depth report on the condition of the chimney so further action can be taken accordingly.
Final thoughts
Chimney surveys and drones play an essential role in ensuring the safety and efficiency of chimneys in homes and buildings. Regular chimney surveys are crucial to detecting potential hazards, preventing fires and ensuring that the chimney is functioning correctly, and the use of drones in chimney surveys offers many advantages, including increased speed, accuracy and safety. As technology advances, it's likely that the use of drones will become even more prevalent in chimney inspections, leading to safer homes and buildings, and surveying processes.
