We have a two story house (Ontario Canada). We bought this nice
house, newly re shingled. For some reason our roof vents let in snow
into the attic, it does not happen all the time. They are typical
rubber vents, 4 inch high or so. 12inch square. I see how this can
happen, the wind blow the snow in, even though it is installed
properly. It only happens when we have a heavy snow fall. Does
everyone have this problem or am I missing something? thanks.
