How to Prevent Snow on the Roof

Winter brings with it a multitude of challenges, from heating your house to removing snow from your property. Depending on where you live, you may have a significant amount of snow to shovel or melt from your driveway, walkways and even from your roof.

 

Because snow removal from roofs can be a risky endeavor, visit the City of Alexandria, Virginia, website to learn about important winter roof safety. Instead of climbing up onto the slippery slope of a roof to remove snow, you may be better off preventing snow on your roof in the first place.

 

Explore options for preventing snow on the roof and choose techniques that will minimize the amount of snow that accumulates on your roof.

 
  1. 1.Heating Cables

    Ice dams can create extensive damage to both the roof and your gutter system with contracting and expanding ice as snow melts and then refreezes.

    When your main concern is ice dams forming along the edges of your roof, heating cables may solve your dilemma. Ice dams can create extensive damage to both the roof and your gutter system with contracting and expanding ice as snow melts and then refreezes.

     

    Install the cable system along the perimeter of the roof and connect it to an extension power cord, plugging it into an outside electrical outlet. The constant supply of low heat will prevent ice dams from forming along roof edges.

  2. 2.Roof Rakes

    The way you prepare the surface depends on the repairs you’re making. If you’re fixing a crack, sand the surface lightly. If you’re fixing popped nails, secure the area around the nail by driving two drywall nails about 2 inches away from the popped nail. If you’re fixing a hole, cut out the drywall in an even square around the hole with a drywall saw.

     

    By standing on the ground and reaching the blade of the rake up to the roof, you can push it into the snow layer at the edge of the roof. This motion will loosen the snow from the roof and cause it to cascade down from the roof. Keep working along the whole perimeter of the roof to remove snow from your roof.

  3. 3.Calcium Chloride Tablets

    Instead of cables that use electricity or a roof rake that requires effort to maneuver, you could also just toss a few calcium chloride tablets up onto your roof wherever you want to melt the snow. The chemical reaction of the calcium chloride will create effective heat, which will melt show away from your rooftop. For best results, use the roof-melt tablets on an ongoing basis to prevent the snow from accumulating to a deep layer.

  5. 4.Cautions

    Rooftops are dangerous places in the best of conditions. During the winter with snow and ice covering a sloping roof, you should avoid climbing up to your roof and trying to walk on it. Whatever method you choose to use for preventing snow build-up on your roof, make sure you can apply or install it from the ground. If you cannot install a snow-melting product without accessing the roof, consider hiring a professional who will know how to complete the job as safely as possible.
