I'd like to add ridge vents. With a pitch of 6 in 12, I want to be able
to throw a rope across the ridge for safety if I work up there in the
future.
Will a rope crush a ridge vent? The metal ridge vents in my
neighborhood look bent.
I see three kinds for sale:
Air Vent Multi-Pitch Filter (aluminum)
Air Vent Shinge Vent II
Dow Corning Vent-Sure Rigid Roll
What's best?
Not sure. Mine are vinyl and have been doing a good job for almost 15
years. The installation is more important than the brand--you don't
want them to leak.
I've read that Shingle Vent II is the least likely to leak in various
weather conditions, such as blowing snow. I chose Vent-Sure Rigid Roll
because it has no external baffle for a rope to damage.
