What snow says about your home’s insulation

In Nebraska, winter usually means snow. When the flurries fly, you can shovel your driveway and clear off your car, but what about your roof? Know what your snowy roof says about your home’s insulation and when to clear the snow away from your rooftop.

Snow on the roof and insulation

If you pay attention to the snow on your roof, you’ll get a hands-free, easy way to check your home’s insulation. After the snow falls, is your roof still covered in white or has the snow melted away? Watching the snow coverage on your roof will help you gauge the quality of your home’s insulation.

Melting snow and poor insulation

People tend to rejoice when snow melts but if that snow is melting off your roof, it could be a problem. Generally, the less snow you see on the roof of a house, the worse that home’s insulation is. When a house is leaking heat out of the roof, it will melt the snow. The melted snow may also form icicles hanging from your gutters. Homes that leak heat have poor insulation, which means you may need to contact a roofing and insulation expert to get that replaced. All that leaked heat is contributing to high energy bills and an expensive winter. Another downside of poor insulation is the potential for leaky roofs. Constant freezing and thawing throughout the winter may lead to ice forming under your shingles, causing water damage to your roof.

Snowy roof benefits

If your roof stays covered in a snowy blanket, it’s a good indication that your insulation is in good shape. Insulation is designed to lock heat inside, which would prevent it from heating your roof and melting the snow. When your insulation is doing its job, the surface temperature of the roof will stay cool all winter long. A light layer of snow can also work with your insulation, acting as a barrier between your home and the outside. This barrier helps keep the cold winter winds out and the warm, cozy heat inside your home.


Should you be worried about heavy snowfall on the roof?

A little snow on the roof is a good sign but a heavy dumping of snow can be an issue. If new snow piles onto your roof before the old layer has a chance to melt away, the accumulation becomes quite heavy. Roofing experts report that most roofs max out at two feet of dense, heavy snow or four feet of light, fluffy snow. Until your home has reached those levels, you have nothing to worry about. If you do get dumped on, it might be time for a wintery wakeup call to avoid any damage to your home.

Roof snow removal

Clearing snow from your roof is never fun and it’s always dangerous. Extreme winter weather conditions make the hazard for falling a real danger. If you’re going to attempt roof snow removal, get the right tools to increase your reach and help you clear the snow. However, the best way to attack the snowy roof dilemma is to call the professionals. Roofing companies will offer snow removal for a couple hundred dollars, which is well worth it considering you avoid freezing temperatures, slipper ladders and fall risks.
