Coming Soon To Your Local Neighborhood Crazy Michigan Weather: Snow on your roof 6”-10”…30? temp at 6 a.m. & 5? temp at 6 p.m. This causes melting snow on your roof, driveway, and sidewalk! Melting snow on your driveway or walkway is okay..the water ?ows into the street or onto your lawn. Melting snow on your roof, not so good. This “meltwater” runs down to your aluminum gutters and freezes. As the snow continues to melt runs down to your gutter that is ?lled with frozen water……………… bam…ice dam!
Q- What can a homeowner do to prevent an ice
dam or more of an ice dam? A- Using a snow rake, remove 4?-6? of snow from the edge of your house by the gutters. Throw calcium chloride onto the roof to help melt any residual ice on the roof. Pour calcium chloride into a panty hose, tie it off and place in your gutters every 6?-8? to help keep the gutter and downspout from freezing.
Q- I have a new roof, why do I have an ice dam? A- A new roof does not prevent ice dams. Even the very best roo?ng system cannot prevent ice dams, it can only minimize the damaging effects caused by ice dams.
Q- What causes an ice dam?
A- Simply put; there are three components needed to create an ice dam.
1) inadequate or poor ventilation; National Building Codes and roo?ng manufacturers require 1 square foot of ventilation for every 300 sq. feet of attic space above the living / heated space. 2) inadequate or poor insulation; National Building Codes require an r-49 for attic insulation, that?s about 13” of blown-in cellulose insulation. 3) weather; If we don?t have these severe weather conditions, we wouldn?t have the situation.
