How do you effectively prevent ice damming during Winter aside from roof raking of snow?

Question

Seems like when I roof rake I pull the snow right to the gutter system and it ends up building up and icing over. North side facing roof is the biggest problem. There is a rubber liner extending up part way under the roof itself but my concern is that may not be suffient as I see all the build up.

Answer 1

best way i found is too add insulation to mattic and add ice cables to roof. they will create a channel for water to run off. they can be bought at home depot

Answer 2

The only things you can do now is to have proper air flow throughout the attic space(You can never over ventilate and attic space), and also make sure that you have a very good insulation level in the attic floor. One more thing that can be done in conjuction with these other two things, is to add ice damn protection under the roof shingle the next time you reroof the house. You will be surprised how effective airflow will help.

Answer 3

the damming is due to insufficiet aiflow / insulation in the Attic. The Best solution is to have goo airflow from the eave to the ridge of the roof.

Answer 4

install a ice melter along the leading edge,
or i throw salt up along the gutter edge before it snows, and some after it snows,

Answer 5

they have heat tape for roofs
