How Snow Affects Your Roof

Roof with Snow
Snow can be a big concern for homeowners, especially when it falls in record-breaking quantities. Under extraordinary conditions, like blizzards and severe snowstorms, many homeowners worry that their roof could be in danger of collapse. To avoid a catastrophe, keep reading to learn about the effects that snow can have on your roof and how you can remove snow if too much builds up.
How Much Snow Is Too Much?
Your home should be built to withstand the maximum amount of snow expected for your area in any given winter. One of the reasons that building codes are established is to help ensure that your home will be safe, even if your area gets heavy amounts of snow. As long as your home was built to code and is structurally sound, your roof should be able to withstand the snow that falls on your roof. 
However, there are some circumstances that could make your roof unsafe. For example:  
  • Your home's roof has sustained structural damage from a problem like termites, water, or fire.
  • Your home was not built or repaired according to local building codes.
  • Your roof was recently replaced with materials that are too heavy for your home's structure. 
If your home meets one of these criteria and a substantial amount of snow is on your roof, then your home could be in danger. Remember that wet snow is far heavier than dry snow, so pay attention to the type of snow that covers your home. Warmer temperatures produce wet snow, while lower temperatures produce dry, fluffy snow.  
What Are the Signs That Your Home Is in Danger of Collapse?
Too much snow can cause big problems, leading to obvious signs of distress. Pay attention to the interior doors of your home. Doors that have always opened and closed easily may suddenly become jammed because the weight on the roof causes your doorways to become warped and distorted.
Additionally, snapping, popping and groaning noises can be a sign of a serious problem. And roof leaks may proceed a roof collapse, so be aware of sudden roof leaks that begin after a heavy snowstorm.
If you notice any of these problems in your home, leave the property as soon as possible and contact a roofer to examine the structure. Your roofer can help you decide whether your roof is safe and what can be done to repair the problem if your roofer finds one.
What Can You Do to Get the Snow Off Your Roof?
The safest way to remove snow from your roof is to contact a professional roofer. Professionals have special safety equipment that enables them to remove snow, break up ice and clear rooftops without putting their workers in danger. 
If you want to remove snow from your roof without help from a roofer, a roof rake may be a possible solution. Roof rakes allow homeowners with pitched rooftops to scrape snow off their home without actually getting on top of the house.
Do not stand on your roof or use a ladder to remove snow, especially if you have heart problems, back problems or other physical limitations that could make snow removal dangerous. Hire a professional instead. 
What If Your Home Is Susceptible to Ice Dams?
If your home is susceptible to ice dams, then have any snow removed even if your roof is not in danger of collapsing. Doing so can help prevent ice dams from forming and can prevent water damage to your roof and walls.
