Here’s some advice
from Ed Nowack, president of JEES in Charlton,
MA.
With the onset of
winter and below-freezing temperatures, one area of trouble that homeowners
often overlook is gutters. If a gutter is not cleaned properly and becomes
plugged by leaves and pine needles, any water that remains in the gutters can
freeze. The weight of the ice in the gutters can caused the gutters to pull
away from the exterior of the house causing damage to both the gutters and the
exterior of the house. Any perforations in the home’s exterior can then allow
precipitation to enter the home. The end result can be water damage and
possibly associated mold contamination inside the exterior wall.
The other
issued with plugged gutters and the ice build-up is ice dam damage. When the
gutters are filled with ice, snowfall can more readily build-up on the edge of
the roof. Any snow melt on the edge of the roof tends to “dam-up” when the
water hits the full gutters instead of travelling down the gutter and away from
the home. With several freeze/thaw cycles, this can cause ice dams to form on
the roof. The weight of the ice can cause damage to the shingles, attic
sheathing and ice shield membrane. This damage will allow water to enter the
attic space once the ice dam melts causing water damage and the likely
formation of mold growth.
Be proactive and
have your gutters cleaned prior to the start of December and/or the first snow
fall.
