ICE DAMS: Are they on their way? Potentially yes, the conditions are ripe for them to happen. Warm air from the inside of your house rises into your attic. The warm air heats up the underside of the roof boards and shingles and melts the snow-covered roof. The water trickles down to the edge or eaves of the roof, where it is unheated and refreezes. The more this happens, the thicker the block of ice that forms at the edge/eave of your roof. Sometimes the water trickles over the block and forms icicles. The warm air keeps meting the snow and the water refreezes until such time it gets dammed and begins to grow upward on the roof instead of forming icicles. The ice block grows and eventually gets under the shingles. It gets bigger and bigger until it gets to the warm air of the attic. At that point it starts to melt again, but this time UNDER the shingles. The melted water flows into your attic, through any insulation and on to your ceilings and into your walls.
The run of storms happening this week and into next, with temperatures running around freezing during the day and going below at night, are the right conditions for ice dams to form. It is likely too late in the season to do much about it to prevent it from happening. But if you want to try, insulating your attic is the key. Keeping the warm air inside your house, and out of your attic helps keep your attic cool enough so it won’t heat up the roof from the underside. Just be careful not to over insulate your attic.
Ice melt wiring on the eaves and in the gutters can help prevent the dams from forming. Something to think about doing next fall. Clearing the build up of snow with a snow rake will also help. Just be careful not to damage the shingles. Damage to roofs occur from the dam itself and even more so by the means used to remove them: hammers, axes, shovels. You can hire someone to use heat or steam to melt the dams, but if you don’t get rid of the snow pack, you’ve wasted your money. Clearing the eaves alone might stop the bleed momentarily but dams will reform if the conditions are right.
