Snow on the Roof
Snow and ice can overburden your roof. It takes about 4 feet of recent snow to cause a roof to collapse; old packed snow weighs more, and a roof is typically only able to handle about 2 feet of this heavy snow. Many roofs are able to withstand 20 pounds per square foot of snow. Although this much snow is rare, it’s important to have a roof rake or plastic shovel with a long extension arm to remove snow during heavy snowfall. After all, our winters can be very unpredictable! Never attempt to remove all snow from the roof, as scraping roof rakes against tiles can cause damage. Instead, leave about 2 inches of snow. A small amount of snow on the roof is fine, and it will safeguard the tiles from scraping damage.
Ice on the Roof
Although icicles hanging from your roof may look like a dazzling winter site, they can be a sure sign of a buildup of ice along your roof’s eaves. They can damage gutters and cause leaks. These icicles are caused by warm attics that melt snow in the middle of the roof which refreezes at the eaves. Make sure to remove the small icicles in order to prevent them from getting bigger and hazardous. We don’t recommend ice melting products, such as rock salts, to be used on your roof. Using them on the roof can rust nails and corrode siding and galvanized gutters. A roof rake can help you get the icicles down as they form, but for a permanent fix, you need to attach a heated cable to the edge of your roof, which melts the ice. Take no chances and hire your roofing professionals at Knockout Roofing to tackle major icicles and ice dams. We have the expertise and equipment to safely take care of the problem.
