Leveraging cutting-edge drone technology allows us to identify problems quickly and safely, providing valuable insights to property owners and managers. In this article, I'll share the most common issues we encounter during roof inspections and how drone technology is revolutionizing this critical maintenance task.

Ponding Water
One of the most prevalent issues we spot during commercial roof inspections is ponding water. This occurs when water accumulates in low spots on the roof and doesn't drain properly. Flat or low-slope roofs are particularly susceptible to this problem.
"Standing water can lead to increased weight load, degradation of materials, and eventual leaks."
Ponding water can cause significant damage over time, weakening the roof structure and potentially leading to leaks. Our drones can easily identify areas of standing water, even in hard-to-reach corners of large commercial roofs.
Membrane Damage
Commercial roofs often use single-ply membranes like EPDM, TPO, or PVC. These materials are durable, but they can suffer damage from various sources. Common types of membrane damage include:
Tears and punctures
Blistering
Shrinkage
UV degradation
Drone inspections allow us to capture high-resolution images of the entire roof surface, making it easy to spot even small areas of membrane damage that might be missed during a traditional walkthrough inspection.
Flashing Deterioration
Flashing is critical for preventing water infiltration around roof penetrations, edges, and transitions. Unfortunately, it's also one of the most common areas where we find issues during inspections. Problems with flashing can include:
Separation from the roof surface
Cracking or splitting
Corrosion (for metal flashing)
Missing or loose fasteners
Our drones can get up close to these vulnerable areas, providing detailed imagery that helps identify flashing problems before they lead to leaks.
Improper Drainage
Effective drainage is crucial for the longevity of any commercial roof. During our inspections, we often find issues related to poor drainage, such as:
Clogged or blocked drains and gutters
Improperly sloped roof surfaces
Insufficient number of drains for the roof size
Drone technology allows us to create accurate 3D models of roof surfaces, helping to identify areas with inadequate slope or drainage issues that might not be apparent from ground level.
HVAC and Equipment Issues
Commercial roofs often house various equipment, including HVAC units, vents, and solar panels. These installations can sometimes cause problems for the roof itself. Common issues we encounter include:
Leaks around equipment penetrations
Damage from foot traffic during equipment maintenance
Improper installation leading to roof damage
Our drones can safely inspect around rooftop equipment without the need for technicians to walk on the roof, reducing the risk of additional damage.
Benefits of Drone Inspections
Drone technology has revolutionized the way we conduct commercial roof inspections. Here are some key advantages:
Safety: Drones eliminate the need for inspectors to physically walk on potentially dangerous roof surfaces.
Efficiency: We can inspect large roof areas quickly, saving time and reducing disruption to building operations.
Comprehensive coverage: Drones can access and document hard-to-reach areas that might be missed in traditional inspections.
Detailed documentation: High-resolution imagery and video provide a clear record of roof conditions over time.
Cost-effective: Drone inspections often cost less than traditional methods, especially for large or complex roofs.
"Regular inspections can check for weathering damage, and reflective coatings may be applied to some roof types to reduce UV exposure and thermal shock."
By leveraging drone technology for commercial roof inspections, we can identify issues early, potentially saving building owners thousands of dollars in repair costs and extending the life of their roofing systems.
In conclusion, roof inspections are crucial for maintaining the integrity of your building and protecting your investment. By understanding the common issues we encounter and embracing innovative inspection methods like drone technology, you can stay ahead of potential problems and ensure your roof continues to perform its vital function for years to come.
