In Calgary’s ever-changing climate—where spring rains, summer storms, and winter snow all play a role—gutter systems face constant challenges. One popular solution to keep gutters clean is the use of micro-mesh gutter guards, like those offered by LeafFilter. But a common question among homeowners in the region is: Can mold grow on these systems?
Let’s take a closer look at the conditions in Calgary and whether micro-mesh gutter guards are truly mold-resistant, plus what steps you can take to keep your system in top shape.
The Short Answer: Yes, But It’s Preventable
Mold can grow on any surface—even micro-mesh gutter guards—if the conditions are right. Calgary’s moisture-heavy springs and early snow melts can create the damp environments mold loves. When organic debris (like leaves, pine needles, or dirt) collects on top of the mesh, it can trap moisture and create a breeding ground for mold or mildew.
Why Mold Might Form on Gutter Guards in Calgary
Trapped Debris on the Mesh Surface
Even the finest mesh systems can accumulate dirt, leaves, and pollen—especially during Calgary’s windy autumns or after a storm.Lack of Maintenance
While LeafFilter and other gutter guard systems are designed to reduce the need for cleaning, they are not 100% maintenance-free. Without occasional rinsing, organic matter can linger.Prolonged Moisture Exposure
Snowmelt and freeze-thaw cycles in Calgary can lead to persistent dampness on your roof and in your gutters, which can encourage mold growth if debris is present.
