It's that time of year again. That snow that is pretty for some is scary for others. You have experienced, read or heard about ice damming. You are familiar with the damage the phenomena can cause. Perhaps your Association has even spent several hundred thousand or even over a million dollars on roofing improvements and/or replacements within the last few years. Why do we have leaks from ice damming? Was the roof replacement performed correctly or designed correctly? The answer is simple, with a properly designed and installed roof system, the possibility of damage resulting from ice damming should be significantly reduced.
While shovels, snowblowers, plows, and deicing agents are used to clear snow and ice from driveways and sidewalks during the winter, removing frozen precipitation from the roof of a house is a bit more challenging. As snow and ice piles up on the roof and subsequently thaws out, the melt-water can sometimes result in damage to the interior of the structure.
