Roof raking helps clear snowfall from your roof and, in turn, you hope that this prevents ice dams. But can roof raking actually cause them? Generally, no, it cannot. But you should note that while, in some cases, you might successfully prevent ice dams from forming near the edge of your roof by keeping it cleared with a roof rake, they could still form higher up on the roof, where you are unable to reach. This may leave you wondering: Does roof raking prevent ice dams? While it is not a 100% guaranteed way to prevent them, it does help.

Knocking down icicles won’t help prevent ice dams, as the dams form on the bottoms of your roof slopes and not on the gutters themselves. However, removing icicles can reduce the risk of injury if they form over heavily trafficked areas, and it can help prevent permanent damage to your gutters. Just be sure to wear safety equipment and always stay on the ground while knocking them down.

When temperatures drop far enough, even rock salt can’t melt the ice. The briny solution freezes before it develops, and the salt doesn’t work, which happens around 10 to 15 degrees Fahrenheit. Keep in mind that wind chill and other factors impact ice-melting progress. Some ice melters, like magnesium chloride, work at colder temperatures and work better for deep winter freezes.

The easiest way to remove snow from a roof involves using a roof rake that allows you to clear snow from the ground. Roof rakes are lightweight and feature adjustable handles, making them user-friendly for most people. This method also helps prevent ice dams and excess snow buildup, reducing the risk of roof damage during winter months.

When should you remove snow from your roof? A good rule of thumb is once six inches of snow accumulates.
