How Tiny Gaps Can Lead to Costly Leaks
When it comes to commercial roofing, it’s often the smallest details that cause the biggest headaches.
Many property owners are surprised to learn that roof leaks rarely come from obvious damage. More often, they begin with tiny gaps at seams, fasteners, or roof transitions. These small openings may seem harmless at first, but over time, they can allow water to infiltrate the roofing system and create costly problems below the surface.
Why Small Gaps Matter
Commercial roofs are constantly exposed to the elements. Heat, cold, rain, wind, and UV exposure all take a toll. As temperatures change, roofing materials naturally expand and contract. Over time, this movement can cause sealants to break down, fasteners to loosen, and seams to separate.
Once even a small gap forms, water doesn’t need much space to get in. Moisture can travel along metal panels, insulation, and decking, often spreading far beyond the original entry point. That’s why leaks frequently show up inside a building in a completely different area than where the water entered.
Common Places Leaks Begin
Some of the most vulnerable areas on a commercial roof include:
-
Seams and panel overlaps
-
Exposed fasteners and screw heads
-
Roof penetrations like skylights, vents, and HVAC units
-
Transitions between different roofing materials
-
Aging sealant and flashing details
These areas require precise installation and ongoing maintenance to stay watertight.
The Hidden Damage You Can’t See
Water intrusion doesn’t just cause visible leaks. When moisture makes its way into a roofing system, it can saturate insulation, reduce energy efficiency, and lead to mold or corrosion. Left untreated, this hidden damage can weaken the roof structure and significantly shorten the life of the entire system.
What starts as a minor repair can quickly turn into a major restoration or replacement if it’s ignored.
Why Regular Inspections Make a Difference
Routine roof inspections are one of the most effective ways to catch small issues before they become expensive problems. A professional inspection can identify early signs of separation, failing sealant, or moisture intrusion that aren’t visible from the ground.
At Glick Roofing Systems, we focus on addressing these details early. Proactive maintenance and timely restorations can extend the life of a commercial roof by years and help building owners avoid unexpected downtime and repair costs.
