When most people imagine a break-in or unauthorized entry, they picture someone slipping through a front door or quietly opening a window. These points get the most attention, and for good reason. They are familiar, visible, and easy to understand.
However, criminals often exploit unexpected entry points—areas that feel unimportant, spaces that no one checks, and corners of a property that seem isolated or inconvenient to secure. As a result, these overlooked locations often become the easiest and most effective ways to access a building.
Here are some of the most common, yet least expected, unexpected entry points intruders use to get inside.
The Roof: Hidden but Vulnerable
Criminals often use the roof to gain access because it is out of sight and rarely monitored.
Common Roof Entry Points:
- Unlocked hatches
- Mechanical rooms that open onto the roof
- Skylights that are easy to lift or break
- Ventilation openings larger than expected
In many cases, reaching the roof is easier than people assume. Once there, intruders can explore entry routes without drawing attention.
Duct Chases and Mechanical Rooms: The Secret Routes
Buildings contain internal pathways that intruders can exploit, such as duct chases, cable runs, and service shafts. These routes connect different areas in ways not obvious from the outside.
Specifically, many mechanical rooms remain unlocked or have minimal access control. Moreover, cameras and alarms often ignore these spaces. Consequently, intruders can bypass public hallways and monitored doors.
Ultimately, what seems like a small infrastructure closet to staff can become a private shortcut for someone with ill intent.
Loading Docks: Activity Creates Cover
Busy loading docks make it easy for intruders to blend in. Trucks arrive, forklifts move, doors stay open, and staff focus on efficiency.
For example, intruders can follow a delivery driver inside, blend in with reflective vests or equipment, or enter while a dock door stays open for airflow. Because of this, the constant movement creates natural cover and lowers suspicion.
Stairwells: Quiet Vertical Pathways
Stairwells are meant for emergencies, not daily traffic, and security often reflects that.
Here, intruders find several opportunities: doors unlocked between floors, lack of cameras or alarms, and doors propped open for convenience. As a result, they can move floor to floor quietly, avoiding monitored areas.
Why Overlooked Spaces Are Dangerous
Criminals think differently than everyday occupants. They search for quiet, neglected, or ignored spaces that provide maximum access with minimal risk. Therefore, a strong security plan protects obvious points like doors and windows but also addresses hidden unexpected entry points.
