With the falling of temperatures and the accumulation of snow, a lot of homeowners, particularly with older or historic slate roofs, have had an irritating winter issue in the form of ice dams. These are large ridges of ice, which develop on the sides of the roof and trap snow behind them.\u00a0<\/span><\/p>\n

The result? Water backing up under shingles, interior leaks, damaged insulation, and costly repairs. Ice dams may seem to be an inevitable struggle for families who attempt to defend their homes during the coldest months of the year.<\/span><\/p>\n

The positive thing is that you can have your slate roof preserved all season long with the help of the appropriate prevention measures.<\/span><\/p>\n

What Causes Ice Dams on Slate Roofs?<\/b><\/h2>\n

Although the slate is very tough, it can still be damaged by an ice dam. Ice dams are also common when the heat escapes in the attic, which heats the roof and leads to the melting of snow. The water is then directed towards the lower end of the roof, where it again refreezes into a solid block of ice. This hard ice accumulation in the drainage forces water to back up beneath the slats.<\/span><\/p>\n

Homes with poor ventilation, insufficient insulation, or heavy snow accumulation experience ice dams more frequently.\u00a0<\/span><\/p>\n

How Ice Dams Damage Slate Roofs<\/b><\/h2>\n

Slate is durable, but the frame beneath it is vulnerable to damage due to the formation of ice dams. The melted water can leak to the underlayment, rot wooden decking, and even grow molds.<\/span><\/p>\n

Repeated freeze\u2013thaw cycles may also loosen sealants or stress flashing around chimneys and valleys.<\/span><\/p>\n
