A heavy buildup of snow and ice on the roof can weaken the structure and lead to a collapse. The amount of strain placed on a roof by ice and snow depends on the moisture content in the precipitation. Most roofs can tolerate 3 to 4 feet of light, fluffy snow, while just 2 feet of wet, compacted snow can cause structural damage. One inch of ice weighs as much as a foot of fluffy snow, so a 4-inch accumulation from a single ice storm has the potential to cause a collapse.
If it’s not possible to remove the buildup safely with a roof rake, call a maintenance or landscaping contractor who’s licensed, bonded and insured to clear the roof as soon as possible. You’ve waited too long if the roof starts to have a sway-back appearance, or your doors and windows pop open or stick shut.
When warmth from the living space rises into the attic, it can melt snow on the roof. On a sloped roof, this runoff will drain down to the edge where it’s cooler. If the water refreezes when the outdoor temperature drops, an ice dam can form that prevents any additional runoff from draining away. Water can then back up under the roofing and infiltrate the attic, ceiling and exterior walls.
To protect your home during severe weather that can cause ice dams and water damage, be sure to:
Water lines that run through unconditioned areas such as the basement, crawl space or exterior walls are vulnerable to freezing during cold spells. When a line freezes, the water inside expands and can burst the pipe. To protect your home during severe weather that may cause pipes to freeze and rupture:
Frequent temperature fluctuations in the winter months cause thaws and freezes that increase the risk of water intrusions to a home. To fully protect your home during severe weather, take these steps to reduce the chance of water seepage or flooding:
Heating equipment that isn’t properly maintained can cause serious harm to a home and its occupants if it malfunctions. To ensure your family’s safety and protect your home during severe weather:
