Why northern homes need more frequent siding replacements
Harsh winter conditions accelerate siding deterioration, resulting in visible damage that can compromise a home’s insulation, energy efficiency, and structural integrity.
Siding replacement in areas with harsh winters is typically performed by professional construction company Yellowknife whose contractors understand the unique challenges of extreme cold, heavy snowfall, and ice buildup. Homeowners can also hire roofing and siding contractors with experience in cold-weather installation to ensure proper sealing, insulation, and durability. Here are three common signs that a siding replacement is needed and why:
1. Cracks, warping, or brittleness
Strong winter winds and flying debris can cause direct impact damage, especially if the siding is already weakened. Freeze-thaw cycles, which are common in the spring, cause moisture to seep into the siding, which expands when it freezes and contracts when it thaws, causing cracks and warping. Low-quality or aged vinyl siding becomes brittle in extreme cold, making it susceptible to cracking. Another factor is improper installation, which can leave gaps that allow ice and snow to accumulate underneath, further distorting the material.
2. Water damage and mold growth
Either poorly sealed seams or old caulking allow water infiltration, or snow and ice buildup on the siding can trap moisture that seeps behind the panels as temperatures rise, causing wood rot, mold and mildew growth. Icicles forming along the edge of siding can indicate that melted water is not draining properly, increasing the risk of prolonged exposure to moisture.
3. Peeling paint and surface erosion
Constant exposure to wind, ice, and UV rays causes paint to peel, fade, or erode over time. If the home is too close to the sidewalk or street, road salt used on nearby driveways or sidewalks can splash onto the siding, causing discoloration and surface wear. Finally, extreme temperature changes cause siding to expand and contract, weakening the protective coating and accelerating deterioration.
Proper siding replacement helps maintain insulation, energy efficiency, and structural protection, ensuring a comfortable and durable home. Homeowners in cold climates should prioritize proper installation with winter-resistant materials designed to withstand extreme cold, humidity, and high winds. Choosing high-quality siding and performing regular maintenance will prevent further damage, enhance curb appeal and extend the life of a home’s exterior, ultimately saving on long-term repair costs.
