i recently blew in my attic with cellulose and i noticed that my ridge vent had gotten plugged up from all the dust is it better for me to remove the ridge vent and try to match up the shingles or is it better for me to put a few box vents in???
I think it would be a better idea to clean out the ridge vent with a vacuum cleaner or possibly a leaf blower from outside.
This is assuming that their are any soffit vents that are still clear. Without the soffit vents the ridge vent can't work well.
