As winter approaches, many homeowners may be tempted to use salt to prevent the formation of ice dams on their roofs and gutters. It seems like an easy solution, but it’s a course of action that can cause more harm than good. Keep reading to learn why experts don’t recommend using this method and discover safer alternatives.
What Happens When You Use Salt to Melt Ice Dams?
Salt, while effective in melting ice, can harm your home. It’s corrosive, meaning it is detrimental to metal structures like gutters and roofs. Using salt to prevent or deal with ice formations in winter can contribute to costly repairs and replacements in the future. The damage this method causes isn’t always immediately apparent. However, over time, the repeated use of salt can weaken and reduce the lifespan of your roof and gutter system.
Melting the ice dams using salt can also harm the environment. When the salt washes off your roof with melted snow or rain, it can travel to your yard and nearby bodies of water. This high salt concentration can hurt plants, contaminate groundwater and negatively affect the delicate balance of local aquatic ecosystems.
Safer Ways to Prevent Ice Formation in Gutters
Invest in Heated Gutter Cables
Heated gutter cables can prevent ice buildup without harming your home or the environment. At Barry Best Seamless Gutters, we offer Helmet Heat®, a self-regulated heat cable installed in gutters, downspouts and the interior panel of gutter guards. It can keep gutters above freezing temperatures to reduce the likelihood of ice dams.
Ensure Sufficient Attic Ventilation and Insulation
Ice dams can form on your roof because of insufficient attic ventilation and insulation. Uneven roof temperatures can result from a poorly insulated and ventilated attic. If this is the case, snow can melt on the highest points of your roof and refreeze on its edges. A professional inspection can reveal if you need to improve your attic ventilation and insulation.
Keep Your Gutters Clean
Regular, professional gutter maintenance can also prevent the conditions that lead to ice dam formation. Clogged gutters can cause standing water on your roof, which can freeze in cold temperatures. Have your gutters cleaned at least twice a year to keep them unobstructed.
Installing a gutter protection system is another way to keep your seamless gutters efficient and clog-free. Gutter guards will prevent leaves, twigs, pine needles and other debris from entering your gutters. As a result, you won’t have to worry about frequent cleanings.
