Drone Roofing Facade Inspection

Building envelope inspections are necessary to detect long term structural/maintenance issues before they become more critical and costly to correct. Traditional methods used to perform roofing and façade inspections can be slow, expensive and put the safety of inspectors at risk. Drones using high quality sensors can perform this task faster, safer and at a lower cost, all while providing inspection data that is superior to previous methods.

The following are some of the reasons drones are quickly gaining popularity inspecting just about every type of building design and type.

1. Safety
Perfect Perspectives employs only the most experienced pilots. Flying near buildings can present unexpected challenges for lesser experienced pilots such as wind shear, loss of GPS satellites and collisions with nearby obstacles. All of our pilots have many decades of experience flying unmanned aircraft and are very adept at flying without GPS control in congested areas if needed. Our perfect safety record for 13 years straight attests to this fact. A major issue with any method used to inspect building facades is assuring the safety of pedestrians below. Drone inspections are typically scheduled when businesses are closed for this reason. If this is not possible, Perfect Perspectives has developed risk mitigation options to reduce an eliminate risks to persons below. Some building roofs may not be safe for walking loads. This is the perfect use case for drones and no roof access is required.

2. Efficacy
Efficacy is the power to get results efficiently. Drones are perfect for building envelope inspections as they can be in the air within 20 minutes of arriving on site. Even for very tall or large buildings both the facade and roof can easily be inspected in just a few hours. Data and reports can typically be provided within 24 hours. We use a wide variety of software options designed to provide clear, concise and actionable data for every inspection we perform.

3. Cost
Drones can provide inspection data that traditional manual methods can’t, all at a fraction of the cost to mobilize and erect scaffolding or rig skyclimbers/swingstages for a traditional facade inspection for example. A typical drone inspection crew consists of one Remote Pilot, one Sensor Payload Operator and depending on the environment, one or more Visual Observers may also be required.

4. Equipment
Perfect Perspectives operates a fleet of 12 different drones, all tailor-made for a very specific function. We offer drones with 50 megapixel Canon DSLR cameras with a wide variety of high quality lenses. Other drones can capture UHD 6K video. High resolution FLIR thermal imaging cameras are also available. All of our infrared images are accompanied by matching video or photo images for easy identification of locations inspected. For roofing inspections, shooting at nadir angle from 100 feet above provides an much better image than simple walking on a roof with a thermal imaging camera pointed at a oblique angle. This same principle is also why drones can provide a faster and more comprehensive picture of a structure’s condition than an inspector taking only close up photos from a stage.

To summarize, drones offer significant advantages in almost every aspect of both building and roofing inspections. Please contact one of our sales representatives for more information or to book an inspection.
