Key Point 1. Understanding Ice Dams and Their Impact on Stucco 

Ice dams form when heat escapes from your roof, melting snow that refreezes along the edges. As the ice builds up, melting water gets trapped and runs down your exterior walls, including stucco. Over time, this moisture can seep into tiny cracks, leading to blistering, staining, and structural damage. Fact: Ice dams can cause thousands of dollars in water-related damage if not properly managed.


Key Point 2: How Snow Runoff Damages Stucco 

When snow melts rapidly, water often flows down exterior walls and collects at the base. Poor drainage or blocked gutters can cause water to soak into stucco, weakening the surface and promoting mold growth. Eco-Max Tip: Ensure your gutters and downspouts are clean and direct water at least 5 feet away from your home’s foundation to prevent runoff damage. 


Key Point 3: Preventive Measures for Protecting Stucco 

  • Seal Cracks Before Winter: Even small fissures can let in water that expands when frozen. 
  • Install Proper Roof Ventilation: Keeps roof temperature consistent, reducing ice dam formation. 
  • Maintain Gutters and Downspouts: Prevent overflow during snowmelt. 
  • Apply Breathable Waterproof Sealant: Allows moisture vapour to escape while keeping water out.

Eco-Max Construction uses eco-friendly stucco coatings and sealants that are durable, non-toxic, and designed for Calgary’s freeze & thaw conditions. 


Key Point 4: Professional Inspection and Maintenance 

DIY repairs can only go so far. Professional inspections help identify early signs of water infiltration and thermal bridging. Eco-Max Construction uses infrared scanning and moisture detection tools to assess hidden damage and prevent long-term deterioration.


Conclusion: 

Ice dams and snow runoff may seem like routine winter challenges, but they can cause serious harm to your stucco if ignored. Preventive maintenance from sealing and cleaning to professional inspection, ensures your Calgary home remains warm, dry, and protected all season long.
