Snow-covered rooftops might paint a serene winter picture, but for homeowners residing in areas frequently hit by snow, this can be a cause for concern. The weight of the snow, combined with ice dams and freezing temperatures, can wreak havoc on a roof. But fear not, for there are roofing solutions specifically designed to combat these challenges.
The Detrimental Effects of Snow on Roofs
Snow, which can weigh up to 20 pounds per cubic foot, can significantly increase the weight burden on a roof. This weight can lead to the formation of ice dams, which are created when attic heat melts the snow on the roof. This melted snow then flows to the overhangs, where it refreezes. Over time, this process results in ice accumulation, forming a dam that hinders proper water drainage. If left unchecked, this can lead to water seepage, causing cracks, leaks, and extensive water damage. Moreover, the expansion of freezing water can exert immense pressure on porous roofing materials, leading to further damage.
Why Lightweight Roofs are Essential in Snowy Regions
Snow and ice dams can significantly increase the weight on a roof. This is especially concerning for roofs made of heavy materials like asphalt shingles or clay tiles. For instance, the combined weight of snow and asphalt shingles can lead to roof truss failures.
Furthermore, clay tile roofs, which can absorb up to 15% of their weight in moisture, might require additional reinforcement to bear heavy snow loads.
Here’s a quick comparison of the weight of common roofing materials:
- Metal Roofing: Up to 1.6 lbs. per sq. ft.
- Wood Shingles or Shakes: Up to 4.5 lbs. per sq. ft.
- Asphalt Shingles: Up to 5 lbs. per sq. ft.
- Clay or Concrete Tile: Up to 10 lbs. per sq. ft.
Metal roofing, being both durable and lightweight, reinforces the roof deck without adding unnecessary weight. Moreover, its non-porous nature ensures that snow and ice slide off before accumulation.
The Significance of Non-Porous Roofs
Porous roofs absorb water, which, when frozen, expands. This expansion can strain the roofing material, leading to cracks, splits, and deterioration after repeated freeze/thaw cycles. Traditional materials like asphalt shingles, clay tiles, and wood shakes are porous, making them less suitable for snowy regions. In contrast, metal roofs are non-porous, making them impervious to both snow and water.
Ensuring Proper Ventilation to Prevent Ice Dams
A well-ventilated roof ensures consistent cold air circulation in the attic, preventing the formation of ice dams. It’s crucial to choose roofing materials that either:
- Can be installed on battens.
- Can be attached directly to the roof deck but have a built-in airspace of at least ¾”.
Materials like asphalt shingles, which are directly nailed to the roof deck without any underlying airspace, are not ideal in this regard.
