After reading the previous posts about snow getting in I am not sure. Although I do believe that if snow can get in a ridge vent then it can get in a regular vent cap.
My builder has never used them and said he won't guarantee against water or snow damage.
What do you recommend? I hate the sight of all the vent caps along the side of a roof. Is snow really a problem, aside from the once every 3 year snow storm like that which hit the country a few weeks ago.
And are there better types than others to consider? I can't remember exactly what was in my previous house. Some have clear openings that I could see driving rain and snow getting in, but others are like a coarse 3M scrubbing pad that block bugs and possibly snow.
What is preferred?
