Hi folks. I have an problem with my roof vents in the winter, the roof is
low pitch about 4-12 the snow builds up and air from attic causes the snow
to melt creating ice dams at every vent , this can build up during winter
months and create an terrible stress load . I have been looking for taller
vents but can't seem to find any. My attic has blown in fiberglass and 10
inch glass batts over it I'm not sure what else I can do. Any suggestions
would be appreciated.

Assuming the vents are above all of the insulation and they are clear
of all debris, a small fan to ventilate the attic space would help.
But first, I'd get up there and check to see that you don't have any
holes in your insulation that are letting out excess heat.

The problem is you have warm air leaking into the attic, fix that.

I would look for better air circulation. Do you have enough
venting both intake (soffit) and outgo (vents)? Do you have the total
area of each recommended for your area?

I'll second what jmeehan said about the air CIRCULATION.

Especially be sure you have adequate INTAKE vents -- preferably SOFFIT
vents. If you don't have adequate intake vents, the air exiting your
OUTGO vents is being pulled directly from the warm air inside your
house, regardless of the insulation. That outgoing air has got to come
from somewhere and if it's not coming into the attic from the outside
via adequate intake vents, it's coming from the interior of your house.

could you put a bigger pipe around the outside of the vent pipe? or
maybe a smaller one inside of it? that would provide an air space around
the 'hot air'
