WHY ARE THERE LARGE ICICLES ON MY ROOF?
During the cold months, icicles can be seen hanging off roofs and gutters of houses in Albany, New York. It appears quaint and beautiful, but they pose potential dangers. The immediate risks are falling icicles that can injure a passerby or the gutter completely falling off. The less obvious danger is the damage it can do to your home.
Icicles form when the attic temperature is warmer than the outdoor temperature. Heat from the attic melts the snow, runs into the gutter and refreezes. The ice accumulates until icicles can be seen hanging off the roof and ice dams form in the gutter. Melt water eventually builds up behind the dams and over the roof where it does not refreeze. The water pushes through the shingles and comes into the house causing damages to roofs, ceilings, walls and insulation.
How do I prevent icicles from forming on my roof?
Installation of ice guards and heat cables, raking, and building new gutters and roof can minimize the formation of icicles but do not prevent them from occurring. The best way to prevent icicles and ice dams is to cool attic temperature. This can be done by evaluating the insulation in your home and by checking for air leakages. Icicles are caused by the difference in temperature between the roof and the outdoors. Proper insulation and ample ventilation in the attic can prevent icicles and ice dams from forming.
The leakage of warm air from the home through the attic heats up the roof. Sealing the gaps, holes and all crevices that are possible sources of air leakage and adding insulation can prevent icicles and ice dam formation. As a bonus, air sealing and adequate insulation makes your home more energy efficient. It reduces energy usage for cooling and heating by minimizing energy wastage, leading to reduced energy costs.
