The Hidden Risks On Your Roof: What You Can’t See Could Cost You

Winter in Ontario is tough on roofs. While snow-covered rooftops might look picturesque, what’s happening beneath the surface can lead to costly damage if left unchecked. The problem is, just because your roof looks fine doesn’t mean it is fine. Hidden issues like ice buildup, excess weight from snow, and freeze-thaw cycles can weaken your roof, leading to leaks, structural damage, or even collapse in extreme cases.

Potential Winter Roof Concerns

Here are some of the most common but not always obvious roofing problems—especially in winter:

• Ice Dams – When melting snow refreezes at the edges of a roof, it blocks proper drainage, forcing water back under roofing materials and leading to leaks, insulation damage, and mold growth.

• Heavy Snow Load – Accumulated snow adds significant weight to a roof, increasing the risk of sagging, cracking, or, in worst cases, collapse.

• Freeze-Thaw Cycles – Ontario’s fluctuating winter temperatures cause constant freezing and thawing, which expands and contracts roofing materials, leading to cracks and loosened fasteners.

• Hidden Moisture Buildup – Snow sitting on a roof can trap moisture underneath, leading to mold, rot, and insulation damage that isn’t always obvious until it becomes a serious issue.

• Blocked Drains & Gutters – Ice and snow can clog drainage systems, preventing proper runoff. When temperatures rise, backed-up water has nowhere to go, increasing the risk of leaks and pooling.
