With the recent extreme wintery weather conditions in various parts of the country, we have been asked how to handle some of the symptoms, such as roof leaks.
Your local building codes are based upon the average weather patterns for your particular area. For instance, insulation R-values and roof flashing requirements are described in the code book for your area. These building codes are determined by the government and are based on historical data. While many hours go into planning the proper codes for each area, weather systems can sometimes surprise us, as is the case with hurricanes, tornados, earthquakes, and other severe weather.
One phenomenon that can occur during times of heavy snowfall is called an ice dam. The University of Minnesota Extension website describes an ice dam as: “…a ridge of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation, and other areas.”
If snow and ice are on your roof, they may cause your roof to leak. Removing snow from your roof is considered a homeowner maintenance item, as is shoveling your walkway. When the snow on your roof reaches the point that water begins leaking into your home, it becomes a necessity for you to take corrective action. Removing snow from roofs is common in areas of the country that experience heavy snowfalls, such as New York, New Jersey, and Colorado. While snow removal is considered a homeowner maintenance item, we encourage you to contact an expert to assist you with what can potentially be a dangerous task.
In addition to ice dams at the edge of the roof, any openings such as roof vents should be cleared of snow and ice to help prevent water intrusion.
