Our extreme weather in Winnipeg can be a challenge for homeowners, especially when it comes to protecting your roof and home. Ice dams, those stubborn, frozen ridges that form at the edge of your roof during the winter, can cause significant damage. As we do every winter, we want to help prepare you as a homeowner for the coming season change. Discussing the impacts of ice dams before and after winter is important. Today we want to go over how insulation and ventilation plays a crucial role in preventing ice dams and preserving your roof and home in the face of our harsh winters.<\/p>\n
Before we discuss the preventive measures, let’s grasp what ice dams are and how they affect your roof.<\/p>\n
Ice dams are rigid formations of ice that develop along the edges of roofs during cold winter weather. They occur when the upper regions of a roof are warmer than the eaves, causing snow to melt and then refreeze as it reaches the colder edges. This ice buildup can trap water on the roof, leading to various issues, including structural damage, damaged shingles, leaks and potential interior damage. In regions with extreme winter climates like ours, understanding and preventing ice dams is crucial for preserving the integrity of your home and roof.<\/p>\n
Ice dams can have a domino effect of damage. The weight of the ice can strain your roof’s structure, causing it to weaken over time. Additionally, the trapped water can seep under your shingles, potentially leading to rot, mold, and even interior damage. As if that’s not enough, the water may leak into your living space, requiring costly repairs.<\/p>\n
Now that we understand the gravity of ice dams, let’s explore how insulation can help thwart their formation.<\/p>\n
Proper attic insulation is a key player in preventing ice dams. When your attic is well-insulated, it helps maintain a consistent temperature on your roof’s surface. This means there’s less of a temperature difference between the upper and lower portions of your roof, minimizing the conditions conducive to ice dam formation.<\/p>\n
Insulation, such as Fibreglass<\/strong><\/a>, Cellulose<\/strong><\/a> or Spray Foam<\/strong><\/a>, can be added to your attic space to ensure an even, well-regulated temperature. Insulation acts as a barrier to heat loss and heat gain year-round, especially in walls, attics and basements. By keeping your attic and basement temperature consistent during winter, properly installed insulation can prevent snow from melting and refreezing at the eaves, ultimately averting ice dams.<\/p>\n In addition to proper insulation, sealing any air leaks in your attic is crucial. Leaky spots can allow warm air to escape, raising the roof’s temperature and contributing to ice dam formation. Gaps around pipes, vents, and lighting fixtures are common culprits.<\/p>\n Addressing these leaks with caulking or weatherstripping can create a more airtight barrier, ensuring warm air stays inside your living space where it belongs.<\/p>\n Ventilation in your attic can act as a cooling mechanism, aiding insulation in ice dam prevention.<\/p>\nSealing Air Leaks<\/b><\/h3>\n
